- GNU GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
- 59 Temple Place - Suite 330, Boston, MA
- 02111-1307, USA.
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-
- GNU GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term "modification".) Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
- 1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
- 2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) You must cause the modified files to carry prominent notices
- stating that you changed the files and the date of any change.
-
- b) You must cause any work that you distribute or publish, that in
- whole or in part contains or is derived from the Program or any
- part thereof, to be licensed as a whole at no charge to all third
- parties under the terms of this License.
-
- c) If the modified program normally reads commands interactively
- when run, you must cause it, when started running for such
- interactive use in the most ordinary way, to print or display an
- announcement including an appropriate copyright notice and a
- notice that there is no warranty (or else, saying that you provide
- a warranty) and that users may redistribute the program under
- these conditions, and telling the user how to view a copy of this
- License. (Exception: if the Program itself is interactive but
- does not normally print such an announcement, your work based on
- the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
- a) Accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of Sections
- 1 and 2 above on a medium customarily used for software interchange; or,
-
- b) Accompany it with a written offer, valid for at least three
- years, to give any third party, for a charge no more than your
- cost of physically performing source distribution, a complete
- machine-readable copy of the corresponding source code, to be
- distributed under the terms of Sections 1 and 2 above on a medium
- customarily used for software interchange; or,
-
- c) Accompany it with the information you received as to the offer
- to distribute corresponding source code. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form with such
- an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
- 5. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
- 6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
- 7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
- 8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
- 9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
- 10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
- NO WARRANTY
-
- 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
- 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
- END OF TERMS AND CONDITIONS
-
- Appendix: How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- <one line to give the program's name and a brief idea of what it does.>
- Copyright (C) 19yy <name of author>
-
- This program is free software; you can redistribute it and/or modify
- it under the terms of the GNU General Public License as published by
- the Free Software Foundation; either version 2 of the License, or
- (at your option) any later version.
-
- This program is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
- GNU General Public License for more details.
-
- You should have received a copy of the GNU General Public License
- along with this program; if not, write to the Free Software
- Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
- Gnomovision version 69, Copyright (C) 19yy name of author
- Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License. Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary. Here is a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the program
- `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
- <signature of Ty Coon>, 1 April 1989
- Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs. If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library. If this is what you want to do, use the GNU Library General
-Public License instead of this License.

- * acgeneral.m4 (AC_IDENTITY): New function.
- (AC_DEFINE_UNQUOTED): Use it to fix this; due to a
- misunderstanding of m4, this was using its first argument as
- the definition.
-
-Thu May 20 09:21:55 1993 Jim Meyering (meyering@comco.com)
-
- * acspecific.m4 (AC_ALLOCA) [find_stack_direction]: Return the
- value from the recursive call. If it worked before, it was by luck.
- From Bruno Haible <haible@ma2s2.mathematik.uni-karlsruhe.de>.

-
- * acgeneral.m4 (AC_FUNC_CHECK): Include ctype.h instead of stdio.h.

- prototypes.
-
- * acconfig.h: Add GETGROUPS_T.
-
- * acspecific.m4 (AC_PROG_RANLIB): Use : instead of @: for no-op.

- && !CRAY2], instead of AC_TEST_PROGRAM. No need to run a program
- for this.

- code for AC_COMPILE_CHECK. Otherwise it got spurious failures.
-
- * acspecific.m4 (TIME_WITH_SYS_TIME): New macro.

- * Makefile.in (dist): Depend on Makefile. Use gzip instead
- of compress. Link files individually instead of en masse;
- if a link fails, use `cp -f' on the losing file.

- name of a function used in alloca.c) for CRAY-1, CRAY X-MP,
- and CRAY Y-MP.

-
- * acgeneral.m4: Undefine the `shift' builtin.
-
- * acspecific.m4 (AC_PROG_YACC): Use AC_PROGRAMS_CHECK to check for

-
- * acspecific.m4 (AC_STRCOLL): Rewritten to use a test program that
- verifies that `strcoll' does vaguely reasonable ordering.

- --config-cache/-C option, and recommend instead of --cache-file.
- Indent example AC_CACHE_VAL macros for clarity. Add new

- and/or grammar.
-
-2001-04-09 Steven G. Johnson <stevenj@alum.mit.edu>

-
- * AUTHORS: Fix grammar.
-
-2001-04-09 Lars J. Aas <larsa@sim.no>

- In order to check that all the CPP symbols which are AC_DEFINE'd
- are properly templated, autoheader traces
- AC_DEFINE/AC_DEFINE_UNQUOTED. Only literals can be traced, and
- actually tracing non literals produces invalid autoheader input.
- Hence, provide a means to trace calls to
- AC_DEFINE/AC_DEFINE_UNQUOTED with literals.
-
- * acgeneral.m4 (AC_DEFINE_TRACE, AC_DEFINE_TRACE_LITERAL): New
- macros.
- (AC_DEFINE, AC_DEFINE_UNQUOTED): Use AC_DEFINE_TRACE.
- * autoheader.sh: Trace AC_DEFINE_TRACE_LITERAL, not
- AC_DEFINE/AC_DEFINE_UNQUOTED.

- (_AC_PROG_CXX_G): Likewise.
- (AC_PROG_CC): As _AC_PROG_CC_G depends on $ac_objext and

-
- * acgeneral.m4 (AC_CHECK_TOOL): As AC_CHECK_PROG first tests the

-2000-06-16 Akim Demaille <akim@epita.fr>
-
- * acspecific.m4 (AC_EXEEXT, AC_OBJEXT): Don't obsolete them, let

-
- * autoreconf.sh (autoconf, autoheader): Be more conscientious when
- looking for the executable.
- * autoupdate.sh: Likewise.
- * autoheader.sh: Likewise.
- Suggested by Alexandre Oliva.
-
-2000-05-26 Akim Demaille <akim@epita.fr>
-
- Thanks to --program-transform-name, `autoconf' might be install as
- `yo-man-i-am-the-all-mighty-AVt0c0nF-eh-eh'. But when
- `yo-man-i-am-the-all-mighty-AVt0h3Ad3R-eh-eh' and the other tools
- want to trace, they might stupidly invoke the program named
- `autoconf' instead. Pfff, stupid scripts :)
-
- * Makefile.am (editsh): Transfer the names of the install
- `autoconf' and `autoheader'.
- * autoconf.sh: Add a missing period at the end of the comment

- cannot produce object code.
-
- * aclang.m4 (AC_PROG_F77): Remove f2c from the search list.
- * doc/autoconf.texi: Excise mentions of f2c in AC_PROG_F77 docs.
-
-2000-05-26 Mark Elbrecht <snowball3@bigfoot.com>
-
- Currently, AC_PROG_LN_S incorrectly reports yes with DJGPP. This
- is because the DJGPP `ln' emulates soft links for executables by
- generating a stub that in turn calls the real program. This
- feature also works with nonexistent files like in the Unix
- spec. So `ln -s X conftestdata' will generate `conftestdata.exe'
- which will attempt to call 'X.exe'. But this feature only works
- for executables. Fix it.
-
- * acspecific.m4 (AC_PROG_LN_S): Create a sample file and use it to
- test `ln -s'.

-2000-05-26 Akim Demaille <akim@epita.fr>

- The options --build etc. used to set `$build'. *If*
- AC_CANONICAL_SYSTEM was run, then the value of `$build' given by
- the user was saved into `$build_alias', and `$build' was
- normalized using `config.sub'.
-
- Now, let `--build' set `$build_alias' so that scripts with or
- without `AC_CANONICAL_BUILD' have the same semantics. This allows
- to use `AC_CHECK_TOOL' without requiring `config.guess' and
- `config.sub' (which was bizarre anyway).
-
- * acgeneral.m4 (_AC_INIT_PARSE_ARGS): --build, --host and --target

- Do not assign any value to `build_alias', just compute `build', and
- `build_{cpy, vendor, os}'.

- * acgeneral.m4 (_AC_INIT_PARSE_ARGS): Do that.
- (_AC_CANONICAL_THING): Drop the support of `$nonopt'.
-
-
- Documenting --build, --host and --target when configure does not
- handle them causes confusion.
- Suggested by Pavel Roskin.
- Nevertheless configure must not die on such an `unsupported'
- option: it does happen that people build an entire tree of
- packages, some of them expecting `--host' etc. some others not.
- Stressed by Tom Tromey and Ian Lance Taylor.
-
- * acgeneral.m4 (HELP_CANON): New diversion.
- (_AC_INIT_PARSE_ARGS): Don't document these options.
- (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):

-
- * acgeneral.m4 (AH_VERBATIM): Just pass two arguments to AH_OUTPUT
- instead of trying to build what `autoheader' needs: let it handle
- the format by itself.
- * autoheader.m4: Adjust.
- s,tmp/config.h,tmp/config.hin.
-
- The adjustment revealed that `autoconf --trace' is not robust to
- single quotes in its argument.
-
- * autoconf.sh: Fix this issue.
- Rename the escape `$*' as `$%'. Implement `$@'.
- * doc/autoconf.texi: Adjust.
-

-
- mawk suffers a severe performance loss when using `sub' with a
- changing value. On the `configure' script of the fileutils:
- mawk '{ sub (/foo/, foo++) }' -> 14s.
- mawk '{ if ($0 ~ /foo/) sub (/foo/, foo++) }' -> 0.03s.
- mawk '{ sub (/foo/, foo) }' -> 0.03s.
-
- * autoconf.sh (task script, AWK script): Run `sub (__oline__,
- oline)' only in the lines that match `__oline__'.
- Suggested by Paul Eggert.

-
-2000-04-12 Akim Demaille <akim@epita.fr>
-
- * acgeneral.m4 (_AC_INIT_HELP): Move --srcdir in the first
- section.
- Document --help=short and recursive.
- Split the `Directory' section into `Installation directories' for
- --prefix and --exec-prefix, and all the others into `Fine tuning
- of the installation directories'.
- In the latter, don't repeat `in DIR', the user understands, and it
- comes out better.
- Default for --exec-prefix is PREFIX.
- Reported by Kathryn Hargreaves.
- Move --host before --build.
- Fix a test on `$ac_init_help' which was not updated.

-
- Speed ups.
-
- * libm4.m4 (m4_append, m4_list_append): Use m4_define, not define.
- On my machine the former implementation takes 4mn 40s to run the
- test suite. Using m4_define leads to 4mn 15s.
- * acgeneral.m4 (_AC_SUBST): Use AC_EXPAND_ONCE (which uses
- m4_define, not define). 4mn.
- (_AC_DIVERT): Don't use m4_case. Starting from those 4mn, if you
- just move NORMAL* first in m4_case, the test suite is run in 3mn.

-
- * tests/tools.m4 (autoconf --trace): New test.
-
-2000-03-21 Akim Demaille <akim@epita.fr>
-
- * autoconf.sh (task trace): Pipe the output of the first m4 into

- trace endless configure.in expansion.
-
-2000-03-21 Akim Demaille <akim@epita.fr>
-
- Uniform idioms.
-
- * acgeneral.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,

-2000-03-20 Jim Meyering <meyering@lucent.com>
-
- * acspecific.m4 (AC_SYS_LONG_FILE_NAMES): Don't test for existence
- of $ac_xdir. Not only is `test -e' not portable, but the test isn't
- necessary at all; the following mkdir ends up accomplishing the
- same goal. Suggestion from Alexandre Oliva.
-
- * acgeneral.m4 (_AC_INIT_PREPARE_ENVIRONMENT) [setting IFS]: Be careful

-
-2000-03-20 Akim Demaille <akim@epita.fr>

-
- * acgeneral.m4: Formatting changes.
-
-2000-03-20 Akim Demaille <akim@epita.fr>
-
- Don't rely on RS = "\0" to swallow the whole input as a single

- "". gawk understands it as expected.
-
- * autoconf.sh (translate_awk::BEGIN): No longer change RS.

- Instead, accumulate the input in `request'.

-
- Use a single tool to reformat the raw `configure' script output by
- m4.
- Suggested by Paul Eggert.
-
- * autoconf.sh: Stop playing with 2 seds and an AWK to finalize
- `configure', a single AWK program is enough.
-
-2000-03-17 Akim Demaille <akim@epita.fr>
-
- In Autoconf 2.13, although AC_OUTPUT_COMMANDS did double quote its
- arguments, AC_OUTPUT arguments 2 and 3 were not! Currently,
- AC_OUTPUT over quotes too: stop that.
- Reported by Martin Buchholz.
-
- * doc/autoconf.texi (Output): Don't expand on the ternary
- AC_OUTPUT.

- * acspecific.m4 (AC_SYS_LONG_FILE_NAMES): Security fixes: create
- the temp files in a private temporary directory, not directly in
- TMPDIR.
-
-2000-03-17 Akim Demaille <akim@epita.fr>
-
- Install the IFS we need once for all.
-
- * acgeneral.m4 (_AC_INIT_PREPARE_ENVIRONMENT): New macro.

- (_AC_INIT_PREPARE): Use it, no longer set the NLS envvars.
- (_AC_WHICH_A, AC_PATH_PROG): Rely on the default IFS.
- * acspecific.m4 (AC_PROG_INSTALL, AC_FUNC_SELECT_ARGTYPES):
- Likewise.
-
-2000-03-17 Akim Demaille <akim@epita.fr>
-
- * acgeneral.m4 (AC_TRY_CPP, AC_EGREP_CPP, AC_TRY_COMPILE,
- AC_TRY_LINK, AC_TRY_RUN_NATIVE): Simplify the removal of the
- contest files: don't remove them before running the actions, just
- remove them at the end of the macro.
-
-2000-03-16 Akim Demaille <akim@epita.fr>
-
- * acspecific.m4 (AC_FUNC_SELECT_ARGTYPES): Use
- : ${foo='some words'}
- not
- : ${foo=some words}
- since this is not portable: Digital Unix v5.0: `bad substitution'.
- From Nicolas Joly.
-
-2000-03-16 Lars J. Aas <larsa@sim.no>
-
- * libm4.m4 (m4_assert, m4_shiftn): New macros.
- (m4_case,m4_match): Rewrite to use m4_shiftn (for readability reasons).

-2000-03-15 Akim Demaille <akim@epita.fr>
-
- Revamp AC_FUNC_SELECT_ARGTYPES.
-
- * acspecific.m4 (AC_FUNC_SELECT_ARGTYPES): Use a single cache
- variable instead of three.
- Use AC_CACHE_CHECK.
- Shorten the name of the var loops, they are no longer cached.
- Include sys/types.h unconditionally.
- `select' returns an int, fixes Autoconf/46.
- Don't display parens in the user messages.
-
-2000-03-14 Akim Demaille <akim@epita.fr>
-
- * autoheader.sh: Use run_m4f, not run_m4.
-
-2000-03-14 John David Anglin <dave@hiauly1.hia.nrc.ca>
-
- * tests/actest.m4 (AC_ENV_SAVE): Don't consider RANDOM and LINENO
- which some shells update. At least ksh on HP-UX 10.20 and sh on
- IRIX 6.5 do change their `RANDOM' even if `read' via `set'.
-
-2000-03-14 Akim Demaille <akim@epita.fr>
-
- * acgeneral.m4 (AC_ARG_ENABLE, AC_ARG_WITH): No use for @%:@ here,
- no need to over quote $1 in the comments.
-
-2000-03-14 Akim Demaille <akim@epita.fr>
-
- * acgeneral.m4: Replace some ifelse with ifval or m4_default, or
- even nothing when not needed.
- * acspecific.m4: Likewise.
-
-2000-03-14 Akim Demaille <akim@epita.fr>
-
- * acgeneral.m4 (_AC_INIT_PREPARE): Insert the Autoconf version in
- config.log, and the command line which ran configure.
- Kill a couple of useless quote around dollars.
-
-2000-03-14 Akim Demaille <akim@epita.fr>
-

-
- * acgeneral.m4 (AC_DIVERT): Rename _AC_DIVERT.
- (AC_DIVERT): New macro.
- Spread its use where better than a pair of AC_DIVERT_PUSH/POP.
-
-2000-03-14 Akim Demaille <akim@epita.fr>
-
- * acgeneral.m4 (_AC_INIT_BINSH): Remove, useless now that...
- (AC_REVISION): Require AC_INIT, not _AC_INIT_BINSH.
- (AC_INIT): Do what _AC_INIT_BINSH used to.
- Don't require _AC_INIT_VERSION, just call it.
- Rename as _AC_INIT.
- (AC_INIT): New macro, single expansion wrapper around _AC_INIT.
- (_AC_COPYRIGHT_SEPARATOR): New.
- (AC_COPYRIGHT): Use it.
- Require AC_INIT, not _AC_INIT_VERSION.
- * doc/autoconf.texi (Versions): Promote as first section of
- `Setup'.
- Rename as `Notices'.
- Document AC_COPYRIGHT.
- Don't give false reasons for placing AC_REVISION before AC_INIT,
- the place no longer matters.
-
-2000-03-14 Akim Demaille <akim@epita.fr>
-
- * autoconf.sh (trace_m4::smash): Double quote, we don't want the
- result to be evaluated.
-
-2000-03-14 Akim Demaille <akim@epita.fr>
-
- * acgeneral.m4: s/@%:@line __oline__/#line __oline__/g. __oline__
- is not a macro, so there is just no use in avoiding `#'.
-
-2000-03-14 Akim Demaille <akim@epita.fr>
-
- * acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS): When there were no
- CONFIG_FILES, we had to expand _AC_OUTPUT_FILES into the KILL
- diversion, because it is AC_OUTPUT_FILES which undiverted the
- AC_SUBST sed script at its proper place, otherwise it would have
- been undiverted at the end of `configure', leading to an sh syntax
- error.
- Now that we no longer use a diversion, we don't need to call
- AC_OUTPUT_FILES if useless.
- (AC_OUTPUT_FILES): Rename as _AC_OUTPUT_FILES.
- (AC_OUTPUT_LINKS): Rename as _AC_OUTPUT_LINKS.
-
-2000-03-14 Akim Demaille <akim@epita.fr>
-
- AC_ARG_PROGRAM must not be expanded twice, which is likely since
- Automake calls it, and usually users do too. If it happens,
- `--program-prefix=g' actually prepend two (or more) `g'.
-
- * acgeneral.m4 (AC_DEFUN_ONCE): New macro.
- (AC_ARG_PROGRAM): AC_DEFUNed_ONCE. Or is it AC_DEFUN_ONCE'd? :).
- No longer AC_EXPAND_ONCE the help string, the macro itself is
- expanded at most once.
- Rename the here-doc tag EOF_SED as EOF.
-
-2000-03-14 Akim Demaille <akim@epita.fr>
-
- Get rid of the ICMDS diversion.

- (_AC_OUTPUT_COMMANDS_INIT): New growing string.
- (_AC_CONFIG_COMMANDS_INIT, _AC_OUTPUT_CONFIG_STATUS): Adjust.
-
-2000-03-14 Akim Demaille <akim@epita.fr>

-
- * acgeneral.m4 (_AC_INIT_PARSE_ARGS): Stop global double quoting,
- failed experiment.
- Merge all the var=val AC_SUBST(var) into AC_SUBST(var, val).
- (AC_SUBST): Implement support for 2nd arg.
- * doc/autoconf.texi (Setting Output Variables): Adjust.
-
-2000-03-13 Akim Demaille <akim@epita.fr>
-
- Simplify the diversions naming system.
- Suggested by Alexandre Oliva and Lars J. Aas
-
- * libm4.m4 (ifndef): New macro.
- * acgeneral.m4 (AC_DIVERT): New macro, maps a diversion name to
- its value. The diversions now have a short name, e.g., `NOTICE',
- instead of the former macros which had long names, e.g.,
- `AC_DIVERSION_NOTICE'.
- (AC_DIVERT_PUSH): Adjust.
- (AC_DIVERT_POP): Use ifndef.
- (AC_DIVERSION_CURRENT): Rename as `AC_DIVERT_DIVERSION' to stay
- within the `AC_DIVERT' name domain.
- Adjust all callers.
- * acspecific.m4: Adjust all callers.
-
-2000-03-13 Akim Demaille <akim@epita.fr>

-
- * autoconf.sh (tmpbase): New var. Adjust trap code and other tmp
- file names.
- (translate_awk::BEGIN): Set RS to "\0" so that the whole file be a
- single record.
- (translate_awk::trans): Convert from array to function.
- (translate_awk::error): New function.
- (translate_awk::main action): Implement support for ${sep}@ and
- ${sep}*. Use trans() and error().
- (translate_awk): Don't put space before user functions call, it is
- not portable.
- Remove trailing `;', this is not C :).
- (task trace): Quote `$traces' when you eval it, to protect the
- white spaces.
- Propagate `translate_awk' failures to `autoconf.sh'.
- Translate the quadrigraphs.
-
-2000-03-13 Akim Demaille <akim@epita.fr>
-
- Trap on 0 is not executed when `exit' is called without argument.
-
- * autoheader.sh (trap 1 2 13 15): s/exit/exit $?/.
- * autoconf.sh: Likewise.
- Remove translate_awk too.
- * autoupdate.sh: Likewise.
- Handle `--debug'.
-
-2000-03-13 Akim Demaille <akim@epita.fr>
-
- More uniform style in scripts.
-
- * autoheader.sh: s/-eq/=/.
- Uniform ordering of variable initializations, option handling.
- Don't use quotes where useless (foo=$1, not foo="$1").
- Propagate `run_m4' and `run_m4f'.
- Use `$0' in --help.
- * autoconf.sh: Likewise.
- * autoreconf.sh: Likewise.
- * autoupdate.sh: Likewise.
- * ifnames.sh: Likewise.
- * autoupdate.m4: Small bug: at the end `dnl' is disabled, so use
- `m4_dnl'.
-
-2000-03-13 Akim Demaille <akim@epita.fr>
-
- `autoconf --trace': faster.
-
- * autoconf.sh (initialization): New var, new option.
- (option loop): When you need an arg, make sure there is one.
- (run_m4f): New var, which content is that of the former...
- (run_m4): Don't use m4 frozen state files.
- Change all callers.
- Don't pass AC_LOCALDIR, not documented, and unused.
- (task trace): Honor `--verbose' and `--initialization'.
- (globally): Send `--verbose' messages in stderr.
- Fix random typos.
-
-2000-03-13 Akim Demaille <akim@epita.fr>
-
- * acspecific.m4 (AC_PROG_BINSH): Removed.
-
-2000-03-13 Akim Demaille <akim@epita.fr>
-
- Start revamping `autoconf --trace'.
-
- * autoconf.sh (debug): New var, new option.
- Adjust the trap code.
- (task trace): Instead of decoding `m4 --trace' with sed, decode it
- with m4 itself.
- ($silent_m4): New file, which disables m4's `errprint'.
- ($trace_m4): New file. Logistic for the m4 which is in charge of
- decoding the traces of the first.
- ($translate_awk): Transform a user trace request into $trace_m4
- code.

-2000-03-10 Akim Demaille <akim@epita.fr>
-
- Multiple `-e' to egrep are not portable. On IRIX 6.5 and Solaris
- 2.5.1 only the last one is honored:
- > printf "foo\nbar\n" | egrep -e 'foo' -e 'bar'
- bar
- > printf "foo\nbar\n" | egrep -e 'bar' -e 'foo'
- foo
- Reported by Nicolas Joly.
- An alternative would have been to use `sed', unfortunately
- alternation is not portable.
-
- * tests/actest.m4 (join): New macro.
- (AC_ENV_SAVE): Join the egrep patterns into a single big one.
- * tests/Makefile.am (EGREP_EXCLUDE): Rename as FILTER_MACROS.
- Join the egrep patterns into a single big one.
-
-2000-03-10 Jim Meyering <meyering@lucent.com>
-
- * acgeneral.m4 (_AC_CHECK_TOOL_PREFIX): Correct typos in definition:
- add `_' prefix to make the function name match comments and existing
- uses. Remove leading prefix from _AC_CANONICAL_HOST.
-
-2000-03-09 Ossama Othman <ossama@debian.org>
-
- * acspecific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Added some missing
- headers if they exist (needed for some missing prototypes) and
- corrects the signal handler prototype/definition. The signal
- handler prototype is now prepended with an `extern "C"' for C++
- compilers since some platforms explicitly require an `extern "C"'
- signal handler.
-
-2000-03-08 Akim Demaille <akim@epita.fr>
-
- * autoheader.m4 (autoheader::AC_CHECK_HEADERS_DIRENT): Rename as
- (autoheader::_AC_CHECK_HEADERS_DIRENT): to cope with the new name
- of the autoconf:: macro.
- Fixes autoconf/119, reported by Raja R Harinath.
-
-2000-03-08 Akim Demaille <akim@epita.fr>
-

-
- * acspecific.m4 (AC_FUNC_MMAP, AC_FUNC_ALLOCA): Make them C++
- safe: include the right headers, cast the allocations etc.
-
-2000-03-08 Akim Demaille <akim@epita.fr>
-
- The argument of AC_COPYRIGHT should be plain text, not an sh
- comment.
-
- * libm4.m4 (m4_quote): s/$@/$*/.
- * acgeneral.m4 (AC_COPYRIGHT): Prepend `# ' to the lines that go
- on the top of `configure'. Actually, prepend `@%:@ ' so that
- there are as many evaluations on both sides.
- (_AC_INIT_VERSION): No longer strip `# '.
-
-2000-03-08 Akim Demaille <akim@epita.fr>
-
- * tests/Makefile.am (all-local): Remove. It wastes time to have
- testsuite rebuilt each time an ac*.m4 file changes. It is enough
- to build it for each `make check'.
-
-2000-03-08 Akim Demaille <akim@epita.fr>
-
- Leave a diversion exclusively for Copyright notices.
-
- * acgeneral.m4 (AC_DIVERSION_DEFAULTS): New diversion number.

- (_AC_INIT_DEFAULTS): New macro.
- (AC_INIT): Use it.
-
-2000-03-08 Akim Demaille <akim@epita.fr>
-
- Provide a means to specify more Copyright information in
- `configure'. And after all, it suits to `configure --version' too.
-
- * acgeneral.m4 (AC_DIVERSION_DEFAULTS, AC_DIVERSION_INIT_PREPARE):
- New diversion numbers.
- (AC_DIVERSION_INIT): Rename as...

- here...
- (_AC_INIT_PREPARE): to here.
- (_AC_INIT_NOTICE): Remove.

- there is no AC_DEFUN associated with the text to expand.
- (_AC_ARG_ENABLE_HELP_PROLOGUE, _AC_ARG_WITH_HELP_PROLOGUE,
- _AC_ARG_VAR_HELP_PROLOGUE): Remove, instead...

-2000-03-08 Akim Demaille <akim@epita.fr>
-
- * acgeneral.m4 (_AC_INIT_PARSE_ARGS): Fix copy n' paste typos in
- `--with-*', `--without-*' and `*' decoding.
- Reported by Raja R Harinath.
- Fixes autoconf/118.
-
-2000-03-08 Akim Demaille <akim@epita.fr>
-
- Don't dump AC_ARG_PROGRAM help messages if not used.
-
- * acgeneral.m4 (_AC_INIT_HELP): Don't.
- (AC_ARG_PROGRAM): Do.
-
-2000-03-08 Akim Demaille <akim@epita.fr>
-
- Don't dump X help messages when `configure' does not check for X.
-
- * acgeneral.m4 (_AC_INIT_HELP): Don't dump X help messages.
- * acspecific.m4 (AC_PATH_X): Do it.
-
-2000-03-08 Akim Demaille <akim@epita.fr>
-
- No longer rely on /bin/sh to compose the optional parts of
- `configure --help'.

- * acgeneral.m4 (AC_DIVERSION_HELP_BEGIN, AC_DIVERSION_HELP_ENABLE,
- AC_DIVERSION_HELP_WITH, AC_DIVERSION_HELP_VAR,

- (AC_ARG_ENABLE, AC_ARG_WITH, AC_ARG_VAR): Expand once the
- _HELP_PROLOGUE macro which corresponds.
- (_AC_INIT_HELP): Adjust to AC_DIVERSION_HELP_BEGIN and
- AC_DIVERSION_HELP_END.
- (_AC_INIT_NOTICE, _AC_INIT_HELP): Remove the sh code which handled
- the optional help strings.
-
-2000-03-08 Akim Demaille <akim@epita.fr>
-
- AC_OUTPUT_COMMANDS no longer uses a diversion.
-
- * acgeneral.m4 (AC_DIVERSION_CMDS): Removed.
- (_AC_OUTPUT_CONFIG_STATUS): Don't undivert it.
-
-2000-03-08 Akim Demaille <akim@epita.fr>

- find config.guess, install-sh etc.
- Reported by Erez Zadok.

- Use ifval instead of ifelse.
-
-2000-03-07 Mark Elbrecht <snowball3@bigfoot.com>
-
- Support absolute DOS-style paths.
-
- Any character before the colon is accepted because network drives
- can be assigned characters outside the [a-zA-Z] range. DOS-style
- relative paths (?:foo/bar) are also considered absolute for
- Autoconf's purposes since the path '../?:foo/bar' is invalid.
-
- * acgeneral.m4 (AC_OUTPUT_FILES): Treat DOS-style paths (?:*') as
- absolute.
- (AC_OUTPUT_SUBDIRS): Likewise.
- (AC_PATH_PROG): Make pattern for matching DOS-style paths the same
- as that used in AC_OUTPUT_FILES and AC_OUTPUT_SUBDIRS.

- Based on suggestions from Paul Eggert.
-
-2000-03-03 Paul Eggert <eggert@twinsun.com>
-
- Move the quadrigraphs out of the user name space.

-
- * acspecific.m4: Move some macros to a better place.
-
-2000-03-02 Akim Demaille <akim@epita.fr>
-
- Internal macros are named `_AC_'.
-
- * acgeneral.m4 (AC_CANONICAL_TARGET, AC_CANONICAL_BUILD,

-
- * tests/torture.m4 (config.status under extreme conditions):
- Reorganized. Because files required by this test were created
- outside the pair AT_SETUP/AT_CLEANUP, when the test fails and
- autotest extracts this test, the `debug' script does not contain

-2000-02-10 Akim Demaille <akim@epita.fr>
-
- * acgeneral.m4 (AC_OUTPUT_MAKE_DEFS): This is a routine of

- Double quoting the whole body is nicer than just the part that

- Changequote-busters!
- From Dan Ackroyd.
-
- * acgeneral.m4 (AC_INIT_PARSE_ARGS, AC_INIT_PREPARE,
- AC_CACHE_SAVE, AC_PREFIX_PROGRAM, AC_OUTPUT,
- _AC_OUTPUT_CONFIG_STATUS, AC_OUTPUT_MAKE_DEFS, AC_OUTPUT_FILES,
- _AC_OUTPUT_HEADERS, AC_OUTPUT_LINKS, AC_OUTPUT_SUBDIRS): Quit
- playing with changequotes, @BKL@ and Co.! Just quote properly.
-
-2000-02-10 Akim Demaille <akim@epita.fr>
-
- Honor properly the `#define' config.h.in templates.
- Test it.
-
- * acgeneral.m4 (AC_OUTPUT_HEADERS): Rename as...
- (_AC_OUTPUT_HEADERS): this. All callers changed.
- Don't mess with changequote, just quote properly.
- Bug 1. Because of the `#' in `ac_dA', the quotes <<>> were not
- removed, and therefore the sed script contained `<<define>>'
- instead of `define'. Now that the block is properly quoted, there
- is no need to quote `define'.
- Bug 2. Once a `#define' substitution performed, we were branching
- to the top of the sed script (`t top'). This resulted in an
- endless substitution of `#define foo 1' to `#define foo 1'.
- Branching is not enough: you also have to fetch the next input
- line, i.e., use `t' instead of `t t' in ac_dD, and don't output
- `: top' in `config.defines'.
- Though it was correct for `#undef' templates, just apply the same
- transformation to `ac_uD' and `config.undefs'.
- Bug 3. Don't try to preserve what was behind the value in the
- template, since on
- #define NAME "bar baz"
- it leads to
- #define NAME 1 baz"
- Now `ac_dB' catches everything behind the NAME (making sure there
- is at least a space) and `ac_dC' only outputs a space.
- * tests/torture.m4: Check that various forms of `#define' header
- templates are properly handled.
-
-2000-02-10 Akim Demaille <akim@epita.fr>
-
- Avoid calling `rm' without arguments.
-
- * acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS): It is smarter to use a
- quoted here doc to output the section providing defaults for
- CONFIG_*.
- Don't rm the CONFIG_FILES here but in..
- (AC_OUTPUT_FILES) [test -n "$CONFIG_FILES"]: here.
- Hm, actually, no, just don't remove them at all, let the newly
- created files replace the old ones, exactly as in
- AC_OUTPUT_HEADERS.

- Quote properly `m4_split' when registering it.
-
-2000-02-10 Akim Demaille <akim@epita.fr>
-
- The AU-glue code for AC_LINK_FILES was not fully compatible: in

- is wrong.

-
- Fix the handling of `./configure foo=bar' and test it.
-
- * acgeneral.m4 (AC_INIT_PARSE_ARGS, getopt loop): Always define

-
-2000-02-08 Akim Demaille <akim@epita.fr>

- (Invoking autoconf): A better help on --trace.

- $2.
- (Using System Type): Watch out TeX wrapping.
- (Pretty Help Strings): Don't give too long a snippet of --help.

-
-2000-02-08 Akim Demaille <akim@epita.fr>
-
- * acgeneral.m4 (AC_PRO): Use AC_PROVIDE instead of defining
- yourself. This allows to see everything that is AC_PROVIDEd via
- autoconf --trace.
- (AC_SPECIALIZE): define'd, not AC_DEFUN'd.

-
- Arrange that config.status creates the file with the AC_SUBSTing
- engine only if needed.
-
- * acgeneral.m4 (AC_OUTPUT_FILES): Create the sed code only if test

- first argument of AC_SHELL_IFELSE.
-
-2000-02-08 Akim Demaille <akim@epita.fr>
-
- It seems quite delicate to have AC_INCLUDES_DEFAULT insert the
- default headers in the INIT section of configure: the reason is
- that AC_INCLUDES_DEFAULT is called unquoted, and this results in
- an un expected behavior. Thanks to Roman V. Shaposhnick for the
- details.
-
- The current implementation is not satisfying: the default headers
- are defined in the INIT section even if they are not used.
-
- * acgeneral.m4 (Prologue of AC_INCLUDES_DEFAULTS): Dump the
- definition of ac_includes_default in the INIT section of
- configure.

- Don't document the autoheader template twice, one is enough.
- * autoheader.m4 (AC_CONFIG_HEADER): don't hook on this guy, but

-
- * acgeneral.m4 (AC_CANONICAL_THING): Quote the

- * acgeneral.m4 (AC_MSG_ERROR, AC_MSG_ERROR_UNQUOTED): Allow an
- optional $2: exit status.
-
-1999-11-13 Akim Demaille <akim@epita.fr>
-
- Check that the AC_DEFINEs from acspecific.m4 do have a template.
- Fix the discovered bugs.
-
- * tests/atgeneral.m4 (AT_CHECK): Don't just exit 1 when you want
- to propagate the failure of a test: exit with the same exit
- status, at least to preserve 77 (=ignore).
- * tests/syntax.m4 (TEST_MACRO): Run also autoheader. Don't run
- this test on all the macros, some just cannot run without
- arguments.
- * acgeneral.m4 (AC_OUTPUT_CONFIG_STATUS): In the if egrep/fi for
- #define templates, add a `:' to prevent syntax errors in
- config.status when there are no AC_DEFINE performed.
- * autoheader.m4 (AH_TEMPLATE): Don't use _AC_SH_QUOTE here, use it
- in...
- (AH_VERBATIM): here. Now AH_C_UNSIGNED_CHAR is no longer failing
- (formerly it would produce a non backslashed backquote, which
- made sh choke).
-
-1999-11-13 Akim Demaille <akim@epita.fr>
-
- Introduce a means to distinguish failures of `configure' due to
- extern software (so that the test suite doesn't fail on them).
-
- * acgeneral.m4 (AC_MSG_ERROR, AC_MSG_ERROR_UNQUOTED): Allow an
- optional $2: exit status.
- * doc/autoconf.texi: Document.
- * acspecific.m4 (AC_PROG_CC_WORKS, PROG_CXX_WORKS,
- AC_PROG_F77_WORKS): Exit 77 if the compiler does not work.
-
-1999-11-13 Akim Demaille <akim@epita.fr>

- Clean up a bit the handling of the LANG stack. More is needed.
-
- * acgeneral.m4 (AC_LANG_CASE): New macro.
- (AC_LANG_RESTORE): Use m4_case.
- (AC_LINKER_OPTION): Use AC_LANG_CASE.
-
-1999-11-11 Akim Demaille <akim@epita.fr>
-
- * autoconf.texi (Generic Declarations): Fixed a typo which
- prevented `make distcheck' from succeeding.
- * texinfo.tex: Updated for the same reasons.
-
-1999-11-11 Akim Demaille <akim@epita.fr>
-
- Introduce a new style of testing, independent from DejaGNU.
-
-

- * tests/atgeneral.m4: Likewise.
- * tests/atconfig.in: Likewise.
-
-
- Write tests.
-
- * tests/syntax.m4: New file, in charge of checking the validity of
- the sh code produced by the macros defined in acspecific.m4.
- acgeneral.m4 is not checked here, because these macros require
- arguments.
- * tests/suite.m4: New file. Run syntax.m4.
-
-1999-11-10 Akim Demaille <akim@epita.fr>
-
- A test suite will be introduced which tries to run all the
- specific macros, but hasbeen'd macro make configure die with bad
- exit status. So we wish to distinguish live macros from defunct
- macros at the moment they are AC_DEFUN'd, not in their body. Hm,
- defunct, defunct... Hey! That's a good name!
-
- * acgeneral.m4 (AC_DEFUNCT): New macro, comparable to AC_DEFUN,
- but for macros which are no longer defined. Replaces AC_HASBEEN.
- (AC_HASBEEN): Defunct. Well, removed in fact.
- (AC_HAVE_LIBRARY): Don't use AC_DEFUN and AC_HASBEEN, just
- AC_DEFUNCT.
- * acspecific.m4 (AC_UNISTD_H, AC_USG, AC_MEMORY_H, AC_DIR_HEADER,
- AC_INT_16_BITS, AC_LONG_64_BITS): Likewise.
- (AC_XENIX_DIR): It was defunct even before I declared it was: was
- depending upon AC_DIR_HEADER which is defunct. So AC_DEFUNCT'ed
- now.
- (AC_DYNIX_SEQ, AC_IRIX_SUN, AC_SCO_INTL): While we're here, you
- too are defunct now.
- * autoconf.texi (Obsolete Macros): Replace the documentation of
- AC_HASBEEN with that of AC_DEFUNCT.
-

-
- Let Autoconf use autoconf's `--install'.
-
- * m4/Makefile.am: New file.

- * m4/missing.am: Likewise.
- * m4/sanity.am: Likewise.
- * aclocal.m4: Include them.

-
-1999-11-10 Akim Demaille <akim@epita.fr>
-
- Make autoconf support --install.
-
- * autoconf.sh (task install): New task. Extract the set of
- auxiliary m4 files a configure.in depends upon. Install links
- from library files to the local dir so that the packages depends
- only on local extensions. Check that the user includes exactly
- the files she needs.
-
-1999-11-10 Akim Demaille <akim@epita.fr>
-
- Require GNU m4 1.4 (well 1.3 in fact).
-
- Because we are ready to handle the case where there are no frozen
- files, we *have* to pass a -I, which is dangerous in conjunction
- with the silent including of `aclocal.m4': you may include things
- that were not expected. Since anyway handling pre 1.3 complicates
- the task, just require an m4 which supports reloading of frozen
- files.
-
- * acspecific.m4 (AC_PROG_GNU_M4): Check for --reload.
- * autoconf.sh: Likewise
- * autoheader.sh: Likewise.
- * configure.in: Explicitly state the m4 version you want.
-
-1999-11-10 Akim Demaille <akim@epita.fr>
-
- No need for foo="`bar`", foo=`bar` is fine.
- Simplify ${foo} and ${1} into $foo and $1.
-
- * acgeneral.m4 (ac_LF_and_DOT): Remove the double quotes.
- * acspecific.m4 (AC_PROG_CC_C_O, AC_PROG_F77_C_O): Likewise.

- * autoheader.sh: Likewise.
- * autoreconf.sh: Likewise.
- * autoupdate.sh: Likewise.
- * ifnames.sh: Remove all the code and messages related to
- AC_MACRODIR, since ifnames is not related to macros in anyway.
-
-1999-11-10 Akim Demaille <akim@epita.fr>
-
- New version of AC_INCLUDE, which does not glob, nor rely upon the
- shell. Add AC_INCLUDES too. Help tracking multiple inclusions.
-
- * acgeneral.m4 (m4_errprint, m4_warn, m4_fatal): New macros,
- variations around errprint.
- (m4_include_unique): New macro which registers what are the files
- already included, and warns if some are included several times.
- (m4_include, m4_sinclude): New macro, using m4_include_unique.
- (AC_INCLUDE): Is now just a wrapper of m4_include.
- (AC_INIT): Use m4_sinclude, not sinclude.
- (_AC_ERRPRINT): Removed, m4_errprint is here!
- (AC_WARNING, AC_FATAL): Wrappers of m4_warn and m4_fatal.
-
-1999-11-01 Akim Demaille <akim@epita.fr>
-
- * autoheader.sh: No longer rely on a system acconfig.h.
-
-1999-11-01 Akim Demaille <akim@epita.fr>
-
- Be kind to Automake: list the arguments of selected macros
- (for instance AC_SUBST will list each variable which may be
- substitued).
-
- * autoconf.sh (--trace, --output): New options.
- Implement tracing of macros.
- trap also on 0, so that there is no need to rm here and there.
- * autoconf.texi (Output): Document --trace and --output.
-
-1999-11-01 Akim Demaille <akim@epita.fr>
-
- Clean up the macros for testing members of aggregates.
-
- * acgeneral.m4 (AC_CHECK_MEMBER): FATAL if $1 has no dot in it.
- Use AC_INCLUDE_DEFAULTS.
- (AC_C_STRUCT_MEMBER): Removed.
- * acspecific.m4 (AC_STRUCT_TIMEZONE): Adapted to AC_CHECK_MEMBERS.
- (AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Adapted to
- AC_CHECK_MEMBERS and obsoleted.
- (AC_STRUCT_ST_BLOCKS): Adapted to AC_CHECK_MEMBERS.
- * autoconf.texi (AC_STRUCT_ST_BLKSIZE, HAVE_STRUCT_STAT_ST_RDEV):
- Explain they are obsoleted, and how to migrate.
- (AC_STRUCT_ST_BLOCKS, AC_STRUCT_TIMEZONE): Explain that the
- AC_DEFINE changed (but the former #defines remain defined
- currently).
- (AC_C_STRUCT_MEMBER): Removed, replaced by the definitions of
- AC_CHECK_MEMBER and AC_CHECK_MEMBERS.
-
-1999-11-01 Akim Demaille <akim@epita.fr>
-
- Install a uniform set of default includes.

- * autoconf.texi: Adjusted.
-
-1999-11-01 Akim Demaille <akim@epita.fr>
-
- * autoheader.m4 (AH_FUNC_ALLOCA, AH_C_CHAR_UNSIGNED, AH_AIX):
- Don't leave `[]dnl' in pseudo #-comment (actually CPP directives).
-
-1999-11-01 Akim Demaille <akim@epita.fr>
-
- Fix a bit of the brokenness of AC_CHECK_TYPE.
-
- * acgeneral.m4 (AC_CHECK_TYPE_INTERNAL): New macro, inspired from
- the former AC_CHECK_TYPE. This macro is exactly the one that
- ought to be named AC_CHECK_TYPE: it just checks, and executes user
- actions. In the future, this macro ought to be renamed
- AC_CHECK_TYPE.
- There is a big difference with the former AC_CHECK_TYPE: instead
- of grepping in the headers, it tries to compile a variable
- declaration. This is both safer, slower, and better, since now we
- can check for compiler types (e.g., unsigned long long).
- (AC_CHECK_TYPES): The looping and AC_DEFINEing version of the
- previous macro. Uses m4 loops.
- (AC_CHECK_TYPE): Reimplemented on top of AC_CHECK_TYPE_INTERNAL.
- * autoheader.m4 (AH_CHECK_TYPE, AH_CHECK_TYPES): New macros,
- hooked.
- * autoconf.texi (@ovar): New macro, for optional variables.
- (Generic Typedefs): Document AC_CHECK_TYPES.

-
-1999-10-31 Akim Demaille <akim@epita.fr>
-
- Provide a means to specify commands to run before config.status is
- created (and, for symmetry, after it is created).
-
- This is typically needed by Automake so that AC_REPLACEd functions
- go through deansification via
-
- LIBOBJS=`echo $LIBOBJS | sed 's/\.o /\$U.o /g;s/\.o$/\$U.o/'`
-
- and/or by Libtool which needs to define LTLIBOBJS and others:
-
- LTLIBOBJS=`echo $LIBOBJS | sed 's/\.o/\.lo/g'`

-
-1999-10-31 Akim Demaille <akim@epita.fr>
-

- (AC_OUTPUT_HEADERS): Run the AC_LIST_HEADERS_COMMANDS.
-
- * acgeneral.m4 (AC_OUTPUT): Once config.status created, before
- running it, trap to `exit 1' so that config.status is not removed
- if configure is interrupted when config.status is complete.
-
- * acgeneral.m4 (AC_OUTPUT_CONFIG_STATUS): When recognizing
- arguments, accept only foo, and no longer foo:foo.in etc.

-
- config.status: Speed up the creation of config headers (about four
- times faster on Linux).
-
- The previous scheme had three sed commands for each AC_DEFINE: one
- for #define templates, and two for #undef templates (with or
- without trailing spaces). Divide this in three sed scripts
- instead: a one liner that removes the trailing spaces, one for
- #defines, and then the last for #undef.
-
- The real speed up comes from the fact that the #define script
- starts by checkin if the current input line has a #define, and if
- not the script immediately goes to the next line, without running
- the rest of the script as was the case before. Equally for the
- #undef script.
-
- Note that this way, users that don't use #define templates don't
- pay too much the overhead, since the sed script `realizes' quickly
- there are no #define lines. My test case runs in 0.32s with
- #define templates, and 0.24s without. To improve this common
- case, the whole code for #define templates is conditionalized by a
- proper egrep call. The result runs is 0.24s, i.e., almost no cost
- at all.
-
- I made one dangerous change that I carefully evaluated before
- commiting: the sed scripts are cut at 48 lines instead of 12 as
- before. This produces here docs of about 4Kb. I checked many
- `configure's and they all have big here documents, much bigger
- than the 12 lines (for instance AC_FUNC_MMAP produces a 150 lines
- long, 3800+ character here document). So I moved to the well
- known HP UX sed limitations: no more than 100 commands, and there
- are two commands per line now, plus a two command preamble. The
- speed up is noticeable.
-
- * acgeneral.m4 (AC_OUTPUT_HEADERS): Remove the ac_e
- family.
- Changed ac_uD and ac_dD to `...;t t', instead of `...g'.
- Instead of creating `conftest.vals' with both ac_e, ac_d,
- and ac_u family, preprocess to strip the trailing spaces, and
- create `conftest.defines' with the ac_d family, and then
- `conftest.undefs' for the ac_e family.
- Break up both `conftest.defines' and `conftest.undefs'. Insert a
- top label and a global test for `#defines' and `#undef' before.
- Call `conftest.defines' if there are #define in the input.
- Call `conftest.undefs'.
-
-1999-10-31 Akim Demaille <akim@epita.fr>

- * acgeneral.m4: Prefer `>file' over `> file' etc.
- * acspecific.m4: Likewise.
-
-1999-10-31 Akim Demaille <akim@epita.fr>
-
- Rename the family AC_NEED_DECL as AC_CHECK: it is more uniform,
- but keep defining NEED_FOO_DECL when `foo' is not declared. Files
- not using Autoconf behave better when declarations lacks than when
- they are wrong. So the unset position should off, hence #if NEEDS
- instead of #if !HAVE (which is triggered when HAVE is not set).
-
- * acgeneral.m4 (AC_NEED_DECL): Rename as...
- (AC_CHECK_DECL): This. Make sure the arguments are the usual
- IF-FOUND, IF-NOT-FOUND.
- (AC_NEED_DECLS, AC_CHECK_DECLS): Likewise.
- * autoconf.texi (Generic Declarations): Document the changes
- aforementioned.
- * autoheader.m4 (AH_NEED_DECLS): Rename as
- (AH_CHECK_DECLS): This.
- (AH_HOOKS): Hook AH_CHECK_DECLS on AC_CHECK_DECLS instead of
- _NEED_.
-
-1999-10-31 Akim Demaille <akim@epita.fr>
-
- Revamp the handling of the arguments of config.status: instead of
- looping over config_files etc. to recognize the file names, use

- (AC_OUTPUT_COMMANDS): Fix the missing fi;done.
-
-1999-10-31 Akim Demaille <akim@epita.fr>
-
- Add a means to specify commands to be run by config.status. At
- the difference of AC_OUTPUT_COMMANDS, require that the set of
- commands be named, so that both

- (AC_LIST_FILES): New list, which stores arguments of
- AC_CONFIG_LISTS the same as AC_LIST_LINKS stores AC_CONFIG_LINKS
- etc.
- (AC_OUTPUT): No longer rely on $1 to designate the config files:
- register them via AC_CONFIG_FILES. All uses of $1 replaced by
- uses of AC_LIST_FILES.
- (AC_OUTPUT_FILES): Run the commands associated to the
- CONFIG_FILES.

-
-1999-10-05 Akim Demaille <akim@epita.fr>

-1999-10-01 Akim Demaille <akim@epita.fr>
-
- Make the handling of the configuration links (AC_LINK_FILES)
- exactly the same as that of configurations files (AC_OUTPUT_FILES)
- and headers (AC_CONFIG_HEADERS). As a result, it is sane to run
- ./config.status src/libmy_lib
- or
- CONFIG_LINKS=src/lib_mylib:lib/lib_mylib ./config.status
-
- * acgeneral.m4 (AC_LINK_FILES): Use AC_FATAL to diagnose bad
- number of argument.
- Obsoleted (but implemented) in favor of AC_CONFIG_LINKS.
-
- * acgeneral.m4 (AC_CONFIG_LINKS): New macro. Takes space
- separated list of DEST:SOURCES arguments.
-
- * acgeneral.m4: Rename each occurence of AC_LIST_HEADER as
- AC_LIST_HEADERS for consistency.
-
- * acgeneral.m4 (AC_OUTPUT, config.status prologue): Move the
- definition of config_files and config_headers to the top.
- Add the definition of config_links.

-
-1999-10-01 Akim Demaille <akim@epita.fr>
-
- Moving most of the task of creating config.h.in from sh to m4.
- Getting rid of acconfig.h by supply a major new family of macros:
- AH_* which make it possible to insert arbitrary text into
- config.h.in.
-
- * autoheader.m4: Major rewrite: introduction of a set of macros
- AH_ that produce code into config.h.in. There are two sets of
- macros: generic macros, or specialized, documented below. The
- basic idea is that an AC_FOO macro which needs an entry in
- config.h.in should have a sibling AH_FOO which expands into that
- entry. In a near future, these macros will be moved next to their
- siblings.
-
- * autoheader.m4 (AH_VERBATIM, AH_DEFINE, AH_DEFINE, AH_NEED_DECLS,
- AH_CHECK_SIZEOF, AH_CHECK_FUNCS, AH_CHECK_HEADERS,
- AH_CHECK_HEADERS, AH_CHECK_LIB, AH_PROG_LEX, AH_FUNC_ALLOCA,
- AH_C_CHAR_UNSIGNED, AH_AIX, AH_F77_WRAPPERS): New macros.
-
- * autoheader.m4 (End section): Bind AC_ macros to their
- AH_siblings.
-
- * autoheader.sh: Remove the sections in charge of SYMS, TYPES,
- FUNCS, HEADERS, LIBS and DECLS: autoheader.m4 is now in charge of
- these.
-
- * autoheader.sh (options): Added -d, --debug, which does not
- remove the temporary files.
-
- * autoheader.sh: Instead of redirecting stdout to the output
- stream, always output to a temporary file. This allows to change
- slightly the consistency check: before autoheader would check that
- each non documented AC_DEFINE is templated in an acconfig. Now it
- just checks whether the template is in the output file.
-
- * acconfig.h: Completely emptied, the remaining templates
- (_ALL_SOURCE, __CHAR_UNSIGNED__, F77_FUNC, F77_FUNC_,
- HAVE_STRINGIZE, and STACK_DIRECTION) are now either associated to
- their AC_DEFINE, or to one of the new AH_ macros.
-
- * acgeneral.m4: Reordering of the m4 macros which are not specific
- to Autoconf.
-
- * acgeneral.m4 (AC_HAVE_LIB): Promoted from obsolete to hasbeen.

- * acspecific.m4 (AC_FUNC_GETLOADAVG): Check for the kstat_open()
- function in libkstat (on systems such as Solaris). This family of
- functions is preferred since they don't require setgid permissions

- * acspecific.m4 (AC_UNISTD_H, AC_USG, AC_MEMORY_H, AC_INT_16_BITS,
- AC_LONG_64_BITS): Promoted from obsolete to hasbeen.
-
- * autoheader.m4 (AC_DEFINE_UNQUOTED): Define via AC_DEFINE, so
- that we program things only once.
- (AC_DEFINE): Use AC_WRAP and _AC_SH_QUOTE. It is now safe to have
- backquotes and extra spaces in the third argument, without
- yielding a bad result.
-
- * autoheader.m4: Instead of a huge `eval', use a temporary file.
- (option handling): Added --debug, to keep the temporary files.
- Fixed a couple of missing quotes.

- * acgeneral.m4 (AC_INIT_PARSE_ARGS): Improve configure's --help.
-
- * acgeneral.m4 (AC_OUTPUT): Change the root of filenames of
- config.status from $conftest to $confstat.
- The previous patch to make config.status reentrant was wrong,
- because it changed some `conftest' that are used by configure into
- `$conftest', while it was for config.status only. To avoid
- another confusion like this, all the filenames of config.status
- should be `$confstat*', and those of configure should be
- `conftest*'.

- `ac_sed_frag'.
-
- * acgeneral.m4 (AC_OUTPUT): This macro used to open the here

-
- * acgeneral.m4 (AC_HELP_STRING): Rewrite in m4. Have m4 work, and
- give a break to sh.
- (_AC_FOREACH): Be careful not to evaluate the arguments. A loop
- over *quoted* macro names should loop over the macro names, not

-
- * autoconf.texi: Update the direntry for more modern Texinfos.

-
-1999-09-07 Gary V. Vaughan <gvaughan@oranda.demon.co.uk>
-
- * Makefile.in (INSTALL, standards.info, autoconf.info): MiKTeX

- filename.
-
-1999-09-07 Steven G. Johnson <stevenj@alum.mit.edu>

- as first argument.
-
- * acgeneral.m4 (AC_CHECK_FILES): Use AC_FOREACH for looping,
- instead of the shell's loop.
-
- * acgeneral.m4 (AC_TR): In addition to transliteration, provide a

-
- * acgeneral.m4 (AC_TRY_COMPILE, AC_TRY_LINK): Deal with smart

-Basic Installation
-==================
-
- These are generic installation instructions.
-
- The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation. It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions. Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
- It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring. (Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.)
-
- If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release. If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
- The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'. You only need
-`configure.ac' if you want to change it or regenerate `configure' using
-a newer version of `autoconf'.
-
-The simplest way to compile this package is:
-
- 1. `cd' to the directory containing the package's source code and type
- `./configure' to configure the package for your system. If you're
- using `csh' on an old version of System V, you might need to type
- `sh ./configure' instead to prevent `csh' from trying to execute
- `configure' itself.
-
- Running `configure' takes awhile. While running, it prints some
- messages telling which features it is checking for.
-
- 2. Type `make' to compile the package.
-
- 3. Optionally, type `make check' to run any self-tests that come with
- the package.
-
- 4. Type `make install' to install the programs and any data files and
- documentation.
-
- 5. You can remove the program binaries and object files from the
- source code directory by typing `make clean'. To also remove the
- files that `configure' created (so you can compile the package for
- a different kind of computer), type `make distclean'. There is
- also a `make maintainer-clean' target, but that is intended mainly
- for the package's developers. If you use it, you may have to get
- all sorts of other programs in order to regenerate files that came
- with the distribution.
-
-Compilers and Options
-=====================
-
- Some systems require unusual options for compilation or linking that
-the `configure' script does not know about. Run `./configure --help'
-for details on some of the pertinent environment variables.
-
- You can give `configure' initial values for variables by setting
-them in the environment. You can do that on the command line like this:
-
- ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
-
- *Note Environment Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
- You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory. To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'. `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script. `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
- If you have to use a `make' that does not support the `VPATH'
-variable, you have to compile the package for one architecture at a time
-in the source code directory. After you have installed the package for
-one architecture, use `make distclean' before reconfiguring for another
-architecture.
-
-Installation Names
-==================
-
- By default, `make install' will install the package's files in
-`/usr/local/bin', `/usr/local/man', etc. You can specify an
-installation prefix other than `/usr/local' by giving `configure' the
-option `--prefix=PATH'.
-
- You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files. If you
-give `configure' the option `--exec-prefix=PATH', the package will use
-PATH as the prefix for installing programs and libraries.
-Documentation and other data files will still use the regular prefix.
-
- In addition, if you use an unusual directory layout you can give
-options like `--bindir=PATH' to specify different values for particular
-kinds of files. Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
- If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
- Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System). The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
- For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Specifying the System Type
-==========================
-
- There may be some features `configure' cannot figure out
-automatically, but needs to determine by the type of host the package
-will run on. Usually `configure' can figure that out, but if it prints
-a message saying it cannot guess the host type, give it the
-`--build=TYPE' option. TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
- CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
- OS
- KERNEL-OS
-
- See the file `config.sub' for the possible values of each field. If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the host type.
-
- If you are _building_ compiler tools for cross-compiling, you should
-use the `--target=TYPE' option to select the type of system they will
-produce code for.
-
- If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the host
-platform (i.e., that on which the generated programs will eventually be
-run) with `--host=TYPE'. In this case, you should also specify the
-build platform with `--build=TYPE', because, in this case, it may not
-be possible to guess the build platform (it sometimes involves
-compiling and running simple test programs, and this can't be done if
-the compiler is a cross compiler).
-
-Sharing Defaults
-================
-
- If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists. Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Environment Variables
-=====================
-
- Variables not defined in a site shell script can be set in the
-environment passed to configure. However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost. In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'. For example:
-
- ./configure CC=/usr/local2/bin/gcc
-
-will cause the specified gcc to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-`configure' Invocation
-======================
-
- `configure' recognizes the following options to control how it
-operates.
-
-`--help'
-`-h'
- Print a summary of the options to `configure', and exit.
-
-`--version'
-`-V'
- Print the version of Autoconf used to generate the `configure'
- script, and exit.
-
-`--cache-file=FILE'
- Enable the cache: use and save the results of the tests in FILE,
- traditionally `config.cache'. FILE defaults to `/dev/null' to
- disable caching.
-
-`--config-cache'
-`-C'
- Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
- Do not print messages saying which checks are being made. To
- suppress all normal output, redirect it to `/dev/null' (any error
- messages will still be shown).
-
-`--srcdir=DIR'
- Look for the package's source code in directory DIR. Usually
- `configure' can determine that directory automatically.
-
-`configure' also accepts some other, not widely useful, options. Run
-`configure --help' for more details.

-* Major changes in Autoconf 2.52 -*- outline -*-
-** Documentation
-- AC_ARG_VAR
-- Quadrigraphs
- This feature was present in autoconf 2.50 but was not documented.
- For example, `@<:@' is translated to `[' just before output. This
- is useful when writing strings that contain unbalanced quotes, or
- other hard-to-quote constructs.
-- m4_pattern_forbid, m4_pattern_allow
-- Tips for upgrading from 2.13.
-- Using autoscan to maintain a configure.ac.
-
-** Default includes
-- Now include stdint.h.
-- sys/types.h and sys/stat.h are guarded.
-- strings.h is included if available, and not conflicting with string.h.
-
-** Bug fixes
-- The test suite is more robust and presents less false failures.
-- Invocation of GNU M4 now robust to POSIXLY_CORRECT.
-- configure accepts --prefix='' again.
-- AC_CHECK_LIB works properly when its first argument is not a
- literal.
-- HAVE_INTTYPES_H is defined only if not conflicting with sys/types.h.
-- build_, host_, and target_alias are AC_SUBST as in 2.13.
-- AC_ARG_VAR properly propagates precious variables inherited from the
- environment to ./config.status.
-- Using --program-suffix/--program-prefix is portable.
-- Failures to detect the default compiler's output extension are less
- likely.
-- `config.status foo' works properly when `foo' depends on variables
- set in an AC_CONFIG_THING INIT-CMD.
-- autoheader is more robust to broken input.
-- Fixed Fortran name-mangling and link tests on a number of systems,
- e.g. NetBSD; see AC_F77_DUMMY_MAIN, below.
-
-** Generic macros
-- AC_CHECK_HEADER and AC_CHECK_HEADERS support a fourth argument to
- specify pre-includes. In this case, the headers are compiled with
- cc, not merely preprocessed by cpp. Therefore it is the _usability_
- of a header which is checked for, not just its availability.
-- AC_ARG_VAR refuses to run configure when precious variables have
- changed.
-- Versions of compilers are dumped in the logs.
-- AC_CHECK_TYPE recognizes use of `foo_t' as a replacement type.
-
-** Specific Macros
-- AC_PATH_XTRA only adds -ldnet to $LIBS if it's needed to link.
-- AC_FUNC_WAIT3 and AC_SYS_RESTARTABLE_SYSCALLS are obsoleted.
-- AM_FUNC_ERROR_AT_LINE, AM_FUNC_FNMATCH, AM_FUNC_MKTIME,
- AM_FUNC_OBSTACK, and AM_FUNC_STRTOD are now activated.
- Be sure to read `Upgrading from Version 2.13' to understand why
- running `autoupdate' is needed.
-- AC_F77_DUMMY_MAIN, AC_F77_MAIN: new macros to detect whether
- a main-like routine is required/possible when linking C/C++ with
- Fortran. Users of e.g. AC_F77_WRAPPERS should be aware of these.
-- AC_FUNC_GETPGRG behaves better when cross-compiling.
-
-* Major changes in Autoconf 2.50
-
-** Lots of bug fixes
-There have been far too many to enumerate them here. Check out
-ChangeLog if you really want to know more.
-
-** Improved documentation
-In particular, portability issues are better covered.
-
-** Use of Automake
-All the standard GNU Makefile targets are supported. The layout has
-changed: m4/ holds the m4 extensions Autoconf needs for its
-configuration, doc/ contains the documentation, and tests/ contains
-the test suite.
-
-** Man pages are provided
-For autoconf, autoreconf, autoupdate, autoheader, autoscan, ifnames,
-config.guess, config.sub.
-
-** autoconf
-- --trace
- Provides a safe and powerful means to trace the macro uses. This
- provide the parsing layer for tools which need to `study'
- configure.in.
-
-- --warnings
- Specify what category of warnings should be enabled.
-
-- When recursing into subdirectories, try for configure.gnu before
- configure to adapt for packages not using autoconf on case-insensitive
- filesystems.
-
-- Diagnostics
- More errors are now caught (circular AC_REQUIRE dependencies,
- AC_DEFINE in the action part of an AC_CACHE_CHECK, too many pops
- etc.). In addition, their location and call stack are given.
-
-** autoupdate
-autoupdate is much more powerful, and is able to provide the glue code
-which might be needed to move from an old macro to its newer
-equivalent.
-
-You are strongly encouraged to use it to modernize both your
-`configure.in' and your .m4 extension files.
-
-** autoheader
-The internal machinery of autoheader has completely changed. As a
-result, using `acconfig.h' should be considered to be obsoleted, and
-you are encouraged to get rid of it using the AH macros.
-
-** autoreconf
-Extensive overhaul.
-
-** Fortran 77 compilers
-Globally, the support for Fortran 77 is considerably improved.
-
-Support for automatically determining a Fortran 77 compiler's
-name-mangling scheme. New CPP macros F77_FUNC and F77_FUNC_ are
-provided to wrap C/C++ identifiers, thus making it easier and more
-transparent for C/C++ to call Fortran 77 routines, and Fortran 77 to
-call C/C++ routines. See the Texinfo documentation for details.
-
-** Test suite
-The test suite no longer uses DejaGNU. It should be easy to submit
-test cases in this new framework.
-
-** configure
-- --help, --help=long, -hl
- no longer dumps useless items.
-- --help=short, -hs
- lists only specific options.
-- --help=recursive, -hr
- displays the help of all the embedded packages.
-- Remembers environment variables when reconfiguring.
- The previous scheme to set envvar before running configure was
- ENV=VAL ./configure
- what prevented configure from remembering the environment in which
- it was run, therefore --recheck was run in an inconsistent
- environment. Now, one should run
- ./configure ENV=VAR
- and then --recheck will work properly. Variables declared with
- AC_ARG_VAR are also preserved.
-- cross-compilation
- $build defaults to `config.guess`, $host to $build, and then $target
- to $host.
- Cross-compilation is a global status of the package, it no longer
- depends upon the current language.
- Cross compilation is enabled iff the user specified `--host'.
- `configure' now fails if it can't run the executables it compiles,
- unless cross-compilation is enabled.
-- Cache file
- The cache file is disabled by default. The new options
- `--config-cache', `-C' set the cache to `config.cache'.
-
-** config.status
-- faster
- Much faster on most architectures.
-- concurrent executions
- It is safe to use `make -j' with config.status.
-- human interface improved
- It is possible to invoke
- ./config.status foobar
- instead of the former form (still valid)
- CONFIG_COMMANDS= CONFIG_HEADERS= CONFIG_LINKS= \
- CONFIG_FILES=foobar:foo.in:bar.in \
- ./config.status
- The same holds for configuration headers and links.
- You can instantiate unknown files and headers:
- ./config.status --header foo.h:foo.h.in --file bar:baz
-- has a useful --help
-- accepts special file name "-" for stdin/stdout
-
-
-** Identity Macros
-- AC_COPYRIGHT
- Specify additional copyright information.
-
-- AC_INIT
- Now expects the identity of the package as argument.
-
-** General changes.
-- Uniform quotation
- Most macros, if not all, now strictly follow the `one quotation
- level' rule. This results in a more predictable expansion.
-
-- AC_REQUIRE
- A sly bug in the AC_REQUIRE machinery, which could produce incorrect
- configure scripts, was fixed by Axel Thimm.
-
-** Setup Macros
-- AC_ARG_VAR
- Document and ask for the registration of an envvar.
-
-- AC_CONFIG_SRCDIR
- Specifies the file which `configure' should look for when trying to
- find the source tree (used to be handled by AC_INIT).
-
-- AC_CONFIG_COMMANDS
- To add new actions to config.status. Should be used instead of
- AC_OUTPUT_COMMANDS.
-
-- AC_CONFIG_LINKS
- Replaces AC_LINK_FILES.
-
-- AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS, AC_CONFIG_SUBDIRS,
- AC_CONFIG_LINKS, and AC_CONFIG_FILES
- They now obey sh: you should no longer use shell variables as
- argument. Instead of
-
- test "$package_foo_enabled" = yes && $my_subdirs="$my_subdirs foo"
- AC_CONFIG_SUBDIRS($my_subdirs)
-
- write
-
- if test "$package_foo_enabled" = yes; then
- AC_CONFIG_SUBDIRS(foo)
- fi
-
-- AC_HELP_STRING
- To format an Autoconf macro's help string so that it looks pretty
- when the user executes `configure --help'.
-
-
-** Generic Test Macros
-- AC_CHECK families
- The interface of the AC_CHECK families of macros (decl, header,
- type, member, func) is now uniform. They support the same set of
- default includes.
-
-- AC_CHECK_DECL, AC_CHECK_DECLS
- To check whether a symbol is declared.
-
-- AC_CHECK_SIZEOF, AC_C_CHAR_UNSIGNED.
- No longer need a cross-compilation default.
-
-- AC_CHECK_TYPE
- The test it performs is much more robust than previously, and makes
- it possible to test builtin types in addition to typedefs.
- It is now schizophrenic:
- - AC_CHECK_TYPE(TYPE, REPLACEMENT)
- remains for backward compatibility, but its use is discouraged.
- - AC_CHECK_TYPE(TYPE, IF-FOUND, IF-NOT-FOUND, INCLUDES)
- behaves exactly like the other AC_CHECK macros.
-
-- AC_CHECK_TYPES
- Checks whether given types are supported by the system.
-
-- AC_CHECK_MEMBER, AC_CHECK_MEMBERS
- Check for given members in aggregates (e.g., pw_gecos in struct
- passwd).
-
-- AC_PROG_CC_STDC
- Checks if the compiler supports ISO C, included when needs special
- options.
-
-- AC_PROG_CPP
- Checking whether the preprocessor indicates missing includes by the
- error code. stderr is checked by AC_TRY_CPP only as a fallback.
-
-- AC_LANG
- Takes a language as argument and replaces AC_LANG_C,
- AC_LANG_CPLUSPLUS and AC_LANG_FORTRAN77.
-
-- AC_LANG_PUSH, AC_LANG_POP
- Are preferred to AC_LANG_SAVE, AC_LANG_RESTORE.
-
-** Specific Macros
-- AC_FUNC_CHOWN, AC_FUNC_MALLOC, AC_FUNC_STRERROR_R,
- AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK, AC_FUNC_STAT, AC_FUNC_LSTAT,
- AC_FUNC_ERROR_AT_LINE, AC_FUNC_OBSTACK, AC_FUNC_STRTOD, AC_FUNC_FSEEKO.
- New.
-
-- AC_FUNC_GETGROUPS
- Sets GETGROUPS_LIBS.
-
-- AC_FUNC_GETLOADAVG
- Defines `HAVE_STRUCT_NLIST_N_UN_N_NAME' instead of `NLIST_NAME_UNION'.
-
-- AC_PROG_LEX
- Now integrates `AC_DECL_YYTEXT' which is obsoleted.
-
-- AC_SYS_LARGEFILE
- Arrange for large-file support.
-
-- AC_EXEEXT, AC_OBJEXT
- You are no longer expected to use them: their computation is
- performed by default.
-
-** C++ compatibility
- Every macro has been revisited in order to support at best CC=c++.
-
-Major changes in Autoconf 2.14:
- There was no release of GNU Autoconf 2.14.
-
-Major changes in Autoconf 2.13:
-
-* Support for building on Win32 systems where the only available C or
- C++ compiler is the Microsoft Visual C++ command line compiler
- (`cl'). Additional support for building on Win32 systems which are
- using the Cygwin or Mingw32 environments.
-* Support for alternative object file and executable file extensions.
- On Win32, for example, these are .obj and .exe. These are discovered
- using AC_OBJEXT and AC_EXEEXT, which substitute @OBJEXT@ and
- @EXEEXT@ in the output, respectively.
-* New macros: AC_CACHE_LOAD, AC_CACHE_SAVE, AC_FUNC_SELECT_ARGTYPES,
- AC_VALIDATE_CACHED_SYSTEM_TUPLE, AC_SEARCH_LIBS, AC_TRY_LINK_FUNC,
- AC_C_STRINGIZE, AC_CHECK_FILE(S), AC_PROG_F77 (and friends).
-* AC_DEFINE now has an optional third argument for a description to be
- placed in the config header input file (e.g. config.h.in).
-* The C++ code fragment compiled for the C++ compiler test had to be
- improved to include an explicit return type for main(). This was
- causing failures on systems using recent versions of the EGCS C++
- compiler.
-* Fixed an important bug in AC_CHECK_TYPE that would cause a configure
- script to report that `sometype_t' was present when only `type_t'
- was defined.
-* Merge of the FSF version of config.guess and config.sub to modernise
- these scripts. Add support for a few new hosts in config.guess.
- Incorporate latest versions of install-sh, mkinstalldirs and
- texinfo.tex from the FSF.
-* autoreconf is capable of running automake if necessary (and
- applicable).
-* Support for Fortran 77. See the Texinfo documentation for details.
-* Bug fixes and workarounds for quirky bugs in vendor utilities.
-
-Major changes in Autoconf 2.12:
-
-* AC_OUTPUT and AC_CONFIG_HEADER can create output files by
- concatenating multiple input files separated by colons, like so:
- AC_CONFIG_HEADER(config.h:conf.pre:config.h.in:conf.post)
- AC_OUTPUT(Makefile:Makefile.in:Makefile.rules)
- The arguments may be shell variables, to compute the lists on the fly.
-* AC_LINK_FILES and AC_CONFIG_SUBDIRS may be called multiple times.
-* New macro AC_OUTPUT_COMMANDS adds more commands to run in config.status.
-* Bug fixes.
-
-Major changes in Autoconf 2.11:
-
-* AC_PROG_CC and AC_PROG_CXX check whether the compiler works.
- They also default CFLAGS/CXXFLAGS to "-g -O2" for gcc, instead of "-g -O".
-* AC_REPLACE_FUNCS defines HAVE_foo if the system has the function `foo'.
-* AC_CONFIG_HEADER expands shell variables in its argument.
-* New macros: AC_FUNC_FNMATCH, AC_FUNC_SETPGRP.
-* The "checking..." messages and the source code for test programs that
- fail are saved in config.log.
-* Another workaround has been added for seds with small command length limits.
-* config.sub and config.guess recognize more system types.
-* Bug fixes.
-
-Major changes in Autoconf 2.10:
-
-* Bug fixes.
-* The cache variable names used by `AC_CHECK_LIB(LIB, FUNC, ...)' has
- changed: now $ac_cv_lib_LIB_FUNC, previously $ac_cv_lib_LIB.
-
-Major changes in Autoconfs 2.6 through 2.9:
-
-* Bug fixes.
-
-Major changes in Autoconf 2.5:
-
-* New configure options --bindir, --libdir, --datadir, etc., with
- corresponding output variables.
-* New macro: AC_CACHE_CHECK, to make using the cache easier.
-* config.log contains the command being run as well as any output from it.
-* AC_CHECK_LIB can check for libraries with "." or "/" or "+" in their name.
-* AC_PROG_INSTALL doesn't cache a path to install-sh, for sharing caches.
-* AC_CHECK_PROG, AC_PATH_PROG, AC_CHECK_PROGS, AC_PATH_PROGS, and
- AC_CHECK_TOOL can search a path other than $PATH.
-* AC_CHECK_SIZEOF takes an optional size to use when cross-compiling.
-
-Major changes in Autoconf 2.4:
-
-* Fix a few bugs found by Emacs testers.
-
-Major changes in Autoconf 2.3:
-
-* Fix the cleanup trap in several ways.
-* Handle C compilers that are picky about option placement.
-* ifnames gets the version number from the right directory.
-
-Major changes in Autoconf 2.2:
-
-* The ifnames utility is much faster but requires a "new awk" interpreter.
-* AC_CHECK_LIB and AC_HAVE_LIBRARY check and add the new
- library before existing libs, not after, in case it uses them.
-* New macros: AC_FUNC_GETPGRP, AC_CHECK_TOOL.
-* Lots of bug fixes.
-* Many additions to the TODO file :-)
-
-Major changes in Autoconf 2.1:
-
-* Fix C++ problems.
-* More explanations in the manual.
-* Fix a spurious failure in the testsuite.
-* Clarify some warning messages.
-* autoreconf by default only rebuilds configure and config.h.in files
- that are older than any of their particular input files; there is a
- --force option to use after installing a new version of Autoconf.
-
-Thanks to everybody who's submitted changes and additions to Autoconf!
-I've incorporated many of them, and am still considering others for
-future releases -- but I didn't want to postpone this release indefinitely.
-
-Caution: don't indiscriminately rebuild configure scripts with
-Autoconf version 2. Some configure.in files need minor adjustments to
-work with it; the documentation has a chapter on upgrading. A few
-configure.in files, including those for GNU Emacs and the GNU C
-Library, need major changes because they relied on undocumented
-internals of version 1. Future releases of those packages will have
-updated configure.in files.
-
-It's best to use GNU m4 1.3 (or later) with Autoconf version 2.
-Autoconf now makes heavy use of m4 diversions, which were implemented
-inefficiently in GNU m4 releases before 1.3.
-
-Major changes in Autoconf 2.0:
-
-** New copyright terms:
-* There are no restrictions on distribution or use of configure scripts.
-
-** Documentation:
-* Autoconf manual is reorganized to make information easier to find
- and has several new indexes.
-* INSTALL is reorganized and clearer and is now made from Texinfo source.
-
-** New utilities:
-* autoscan to generate a preliminary configure.in for a package by
- scanning its source code for commonly used nonportable functions,
- programs, and header files.
-* ifnames to list the symbols used in #if and #ifdef directives in a
- source tree.
-* autoupdate to update a configure.in to use the version 2 macro names.
-* autoreconf to recursively remake configure and configuration header
- files in a source tree.
-
-** Changed utilities:
-* autoheader can take pieces of acconfig.h to replace config.h.{top,bot}.
-* autoconf and autoheader can look for package-local definition files
- in an alternate directory.
-
-** New macros:
-* AC_CACHE_VAL to share results of tests between configure runs.
-* AC_DEFUN to define macros, automatically AC_PROVIDE them, and ensure
- that macros invoked with AC_REQUIRE don't interrupt other macros.
-* AC_CONFIG_AUX_DIR, AC_CANONICAL_SYSTEM, AC_CANONICAL_HOST, AC_LINK_FILES to
- support deciding unguessable features based on the host and target types.
-* AC_CONFIG_SUBDIRS to recursively configure a source tree.
-* AC_ARG_PROGRAM to use the options --program-prefix,
- --program-suffix, and --program-transform-name to change the names
- of programs being installed.
-* AC_PREFIX_DEFAULT to change the default installation prefix.
-* AC_TRY_COMPILE to compile a test program without linking it.
-* AC_CHECK_TYPE to check whether sys/types.h or stdlib.h defines a given type.
-* AC_CHECK_LIB to check for a particular function and library.
-* AC_MSG_CHECKING and AC_MSG_RESULT to print test results, on a single line,
- whether or not the test succeeds. They obsolete AC_CHECKING and AC_VERBOSE.
-* AC_SUBST_FILE to insert one file into another.
-* AC_FUNC_MEMCMP to check whether memcmp is 8-bit clean.
-* AC_FUNC_STRFTIME to find strftime even if it's in -lintl.
-* AC_FUNC_GETMNTENT to find getmntent even if it's in -lsun or -lseq.
-* AC_HEADER_SYS_WAIT to check whether sys/wait.h is POSIX.1 compatible.
-
-** Changed macros:
-* Many macros renamed systematically, but old names are accepted for
- backward compatibility.
-* AC_OUTPUT adds the "automatically generated" comment to
- non-Makefiles where it finds @configure_input@ in an input file, to
- support files with various comment syntaxes.
-* AC_OUTPUT does not replace "prefix" and "exec_prefix" in generated
- files when they are not enclosed in @ signs.
-* AC_OUTPUT allows the optional environment variable CONFIG_STATUS to
- override the file name "config.status".
-* AC_OUTPUT takes an optional argument for passing variables from
- configure to config.status.
-* AC_OUTPUT and AC_CONFIG_HEADER allow you to override the input-file names.
-* AC_OUTPUT automatically substitutes the values of CFLAGS, CXXFLAGS,
- CPPFLAGS, and LDFLAGS from the environment.
-* AC_PROG_CC and AC_PROG_CXX now set CFLAGS and CXXFLAGS, respectively.
-* AC_PROG_INSTALL looks for install-sh or install.sh in the directory
- specified by AC_CONFIG_AUXDIR, or srcdir or srcdir/.. or
- srcdir/../.. by default.
-* AC_DEFINE, AC_DEFINE_UNQUOTED, and AC_SUBST are more robust and smaller.
-* AC_DEFINE no longer prints anything, because of the new result reporting
- mechanism (AC_MSG_CHECKING and AC_MSG_RESULT).
-* AC_VERBOSE pays attention to --quiet/--silent, not --verbose.
-* AC_ARG_ENABLE and AC_ARG_WITH support whitespace in the arguments to
- --enable- and --with- options.
-* AC_CHECK_FUNCS and AC_CHECK_HEADERS take optional shell commands to
- execute on success or failure.
-* Checking for C functions in C++ works.
-
-** Removed macros:
-* AC_REMOTE_TAPE and AC_RSH removed; too specific to tar and cpio, and
- better maintained with them.
-* AC_ARG_ARRAY removed because no one was likely using it.
-* AC_HAVE_POUNDBANG replaced with AC_SYS_INTERPRETER, which doesn't
- take arguments, for consistency with all of the other specific checks.
-
-** New files:
-* Comes with config.sub and config.guess, and uses them optionally.
-* Uses config.cache to cache test results. An alternate cache file
- can be selected with the --cache-file=FILE option.
-* Uses optional shell scripts $prefix/share/config.site and
- $prefix/etc/config.site to perform site or system specific initializations.
-* configure saves compiler output to ./config.log for debugging.
-* New files autoconf.m4 and autoheader.m4 load the other Autoconf macros.
-* acsite.m4 is the new name for the system-wide aclocal.m4.
-* Has a DejaGnu test suite.
-
-Major changes in Autoconf 1.11:
-
-* AC_PROG_INSTALL calls install.sh with the -c option.
-* AC_SET_MAKE cleans up after itself.
-* AC_OUTPUT sets prefix and exec_prefix if they weren't set already.
-* AC_OUTPUT prevents shells from looking in PATH for config.status.
-
-Plus a few other bug fixes.
-
-Major changes in Autoconf 1.10:
-
-* autoheader uses config.h.bot if present, analogous to config.h.top.
-* AC_PROG_INSTALL looks for install.sh in srcdir or srcdir/.. and
- never uses cp.
-* AC_PROG_CXX looks for cxx as a C++ compiler.
-
-Plus several bugs fixed.
-
-Major changes in Autoconf 1.9:
-
-* AC_YYTEXT_POINTER replaces AC_DECLARE_YYTEXT.
-* AC_SIZEOF_TYPE generates the cpp symbol name automatically,
- and autoheader generates entries for those names automatically.
-* AC_FIND_X gets the result from xmkmf correctly.
-* AC_FIND_X assumes no X if --without-x was given.
-* AC_FIND_XTRA adds libraries to the variable X_EXTRA_LIBS.
-* AC_PROG_INSTALL finds OSF/1 installbsd.
-
-Major changes in Autoconf 1.8:
-
-** New macros:
-* New macros AC_LANG_C, AC_LANG_CPLUSPLUS, AC_LANG_SAVE, AC_LANG_RESTORE,
- AC_PROG_CXX, AC_PROG_CXXCPP, AC_REQUIRE_CPP
- for checking both C++ and C features in one configure script.
-* New macros AC_CHECKING, AC_VERBOSE, AC_WARN, AC_ERROR for printing messages.
-* New macros AC_FIND_XTRA, AC_MMAP, AC_SIZEOF_TYPE, AC_PREREQ,
- AC_SET_MAKE, AC_ENABLE.
-
-** Changed macros:
-* AC_FIND_X looks for X in more places.
-* AC_PROG_INSTALL defaults to install.sh instead of cp, if it's in srcdir.
- install.sh is distributed with Autoconf.
-* AC_DECLARE_YYTEXT has been removed because it can't work, pending
- a rewrite of quoting in AC_DEFINE.
-* AC_OUTPUT adds its comments in C format when substituting in C files.
-* AC_COMPILE_CHECK protects its ECHO-TEXT argument with double quotes.
-
-** New or changed command line options:
-* configure accepts --enable-FEATURE[=ARG] and --disable-FEATURE options.
-* configure accepts --without-PACKAGE, which sets withval=no.
-* configure accepts --x-includes=DIR and --x-libraries=DIR.
-* Giving --with-PACKAGE no argument sets withval=yes instead of withval=1.
-* configure accepts --help, --version, --silent/--quiet, --no-create options.
-* configure accepts and ignores most other Cygnus configure options, and
- warns about unknown options.
-* config.status accepts --help, --version options.
-
-** Paths and other changes:
-* Relative srcdir values are not made absolute.
-* The values of @prefix@ and @exec_prefix@ and @top_srcdir@ get substituted.
-* Autoconf library files are installed in ${datadir}/autoconf, not ${datadir}.
-* autoheader optionally copies config.h.top to the beginning of config.h.in.
-* The example Makefile dependencies for configure et al. work better.
-* Namespace cleanup: all shell variables used internally by Autoconf
- have names beginning with `ac_'.
-
-More big improvements are in process for future releases, but have not
-yet been (variously) finished, integrated, tested, or documented enough
-to release yet.
-
-Major changes in Autoconf 1.7:
-
-* New macro AC_OBSOLETE.
-* Bugs in Makefile.in fixed.

-
-Major changes in Autoconf 1.6:

-* New macro AC_LONG_64_BITS.
-* Multiple .h files can be created.
-* AC_FIND_X looks for X files directly if it doesn't find xmkmf.
-* AC_ALLOCA defines C_ALLOCA if using alloca.c.
-* --with-NAME can take a value, e.g., --with-targets=sun4,hp300bsd.
-* Unused --no-create option to configure removed.
-* autoheader doesn't change the timestamp of its output file if
- the file didn't change.
-* All macros that look for libraries now use AC_HAVE_LIBRARY.
-* config.status checks three optional environment variables to
- modify its behavior.
-* The usual bug fixes.
-
-Major changes in Autoconf 1.5:
-
-* New macros AC_FIND_X, AC_OFF_T, AC_STAT_MACROS_BROKEN, AC_REVISION.
-* autoconf and autoheader scripts have GNU standards conforming
- --version and --help options (they print their message and exit).
-* Many bug fixes.
-
-Major changes in Autoconf 1.4:
-
-* New macros AC_HAVE_POUNDBANG, AC_TIME_WITH_SYS_TIME, AC_LONG_DOUBLE,
- AC_GETGROUPS_T, AC_DEFINE_UNQUOTED.
-* autoconf and autoheader use the M4 environment variable to determine the
- path of the m4 program to use.
-* The --macrodir option to autoconf and autoheader specifies the directory
- in which acspecific.m4, acgeneral.m4, etc. reside if not the default.
-* autoconf and autoheader can take `-' as their file names, which means to
- read stdin as input.
-* Resulting configure scripts can take a --verbose option which causes them
- to print the results of their tests.
-* AC_DEFINE quotes its second argument in such a way that spaces, magic
- shell characters, etc. will be preserved during various stages of
- expansion done by the shell. If you don't want this, use
- AC_DEFINE_UNQUOTED instead.
-* Much textual processing done with external calls to tr and sed have been
- internalized with builtin m4 `patsubst' and `translit' calls.
-* AC_OUTPUT doesn't hardwire the filenames it outputs. Instead, you can
- set the shell variables `gen_files' and `gen_config' to the list of
- filenames to output.
-* AC_DECLARE_YYTEXT does an AC_SUBST of `LEX_OUTPUT_ROOT', which may be
- "lex.yy" or "lexyy", depending on the system.
-* AC_PROGRAMS_CHECK takes an optional third arg. If given, it is used as
- the default value.
-* If AC_ALLOCA chooses alloca.c, it also defines STACK_DIRECTION.
-* AC_CONST works much more reliably on more systems.
-* Many bug fixes.
-
-Major changes in Autoconf 1.3:
-
-configure no longer requires awk for packages that use a config.h.
-Support handling --with-PACKAGE options.
-New `autoheader' script to create `config.h.in' from `configure.in'.
-Ignore troublesome -lucb and -lPW when searching for alloca.
-Rename --exec_prefix to --exec-prefix for GNU standards conformance.
-Improve detection of STDC library.
-Add AC_HAVE_LIBRARY to check for non-default libraries.
-Function checking should work with future GNU libc releases.
-
-Major changes in Autoconf 1.2:
-
-The --srcdir option is now usually unnecessary.
-Add a file containing sample comments describing CPP macros.
-A comment in config.status tells which host it was configured on.
-Substituted variable values can now contain commas.
-Fix bugs in various feature checks.
-
-Major changes in Autoconf 1.1:
-
-Added AC_STRCOLL macro.
-Made AC_GETLOADAVG check for more things.
-AC_OUTPUT argument is now optional.
-Various bug fixes.

-Autoconf
-
-Autoconf is an extensible package of M4 macros that produce shell
-scripts to automatically configure software source code packages.
-These scripts can adapt the packages to many kinds of UNIX-like
-systems without manual user intervention. Autoconf creates a
-configuration script for a package from a template file that lists the
-operating system features that the package can use, in the form of M4
-macro calls.
-
-Producing configuration scripts using Autoconf requires GNU M4. You
-must install GNU M4 (version 1.4 or later) before configuring
-Autoconf, so that Autoconf's configure script can find it. The
-configuration scripts produced by Autoconf are self-contained, so
-their users do not need to have Autoconf (or GNU M4).
-
-Some optional utilities that come with Autoconf, autoscan and
-autoupdate, use Perl 5.5. However, it is not required in order to use
-the main Autoconf programs. If it is not present, the affected
-Autoconf utilities will not be installed.
-
-The file INSTALL should be distributed with packages that use
-Autoconf-generated configure scripts and Makefiles that conform to the
-GNU coding standards. The package's README can just give an overview
-of the package, where to report bugs, and a pointer to INSTALL for
-instructions on compilation and installation. This removes the need
-to maintain many similar sets of installation instructions.
-
-Be sure to read BUGS (especially if this Autoconf is not an official
-release) and INSTALL.
-
-This version of the package Autoconf uses a fixed version of Automake
-1.4. If ever you alter some Makefile.am (i.e., if you hack Autoconf
-itself), you'll have to use either a more recent release of Automake,
-or download the patch from
-
- http://packages.debian.org/stable/devel/automake.html
-
-Mail suggestions to autoconf@gnu.org, bug reports to
-autoconf-bugs@gnu.org, and patches to autoconf-patches@gnu.org.
-Please include the Autoconf version number, which you can get by
-running `autoconf --version'.

--*- outline -*-
-
-Things it might be nice to do someday. I haven't evaluated all of
-these suggestions... their presence here doesn't imply my endorsement.
--djm & his successors.
-
-
-------------------------------------------------------------------------------
-
-* Soon
-
-** --target & AC_ARG_PROGRAM
-Shouldn't *any* `program' be installed as `$target_alias-program' even
-if AC_ARG_PROGRAM is not called? That would be much more predictable.
-Ian?
-
-** RedHat's Autoconf page
-should be removed.
-
-** AC_CHECK_TOOL...
-Write a test that checks that it honors the values set by the user.
-
-* Autoconf 2.52 or later
-
-** Languages
-Integrate other Fortrans etc.
-
-** AC_CHECK_FUNCS and AC_TRY_LINK_FUNC
-I have still not understood what's the difference between the two
-which requires to have two different sources: AC_LANG_CALL and
-AC_LANG_FUNC_LINK_TRY (which names seem to be inappropriate).
-Wouldn't one be enough?
-
-** autom4te
-Eve it out of autoconf. Install support for Autotest, M4sugar, and
-M4sh. Give a means to trace at the same time as we produce the
-output. autoconf shall use this feature to make autoheader obsolete,
-and to produce some kind of input file for automake which should no
-longer *ever* try to parse Autoconf files.
-
-** Autotest
-Document it.
-
-** Document AC_COMPILE_IFELSE, AC_LANG_PROGRAM etc.
-And make AC_TRY_COMPILE etc. obsolete.
-
-** Autoscan macros
-Can be introduced even before specializing macros. It just means that
-specializing macros will call them. OTOH, this doubles our work,
-since specializing macros will save us from additional typing. But
-the more powerful autoscan is, the better...
-
-** Libtool
-Define once for all the hooks they need, any redefinition of
-AC_PROG_CC etc. is way too dangerous and too limiting. The GCC team
-certainly has requirements too.
-
-** Pentateuch
-Heck, there is nothing after `Deuteronomy'! We're stuck, but we
-_must_ update the `history' section. Can't go to `New testament', we
-might hurt feelings? In addition, it means that the Messiah has come,
-which might be slightly presumptuous :). Still, someone fluent in
-English should write it.
-
-** AC_FUNC_GETLOADAVG
-We must find a solution for this macro which needs to find
-`getloadavg.c'.
-
-** Revamp the language support
-We should probably have a language for C89, and C99. We must give the
-means to the users to specify some needs over the compilers, and
-actually look for a good compiler, instead of stopping at the first
-compiler we find.
-
-In fact, the AC_CHECK_PROG macro and variations have proved their
-limitation: we really need something more powerful and simpler too.
-
-We must take into account the specific problems of the GCC team. We
-must extend AC_CHECK_FUNCS in order to use the headers instead of fake
-declarations as we currently do. Default headers could be triggered
-on when C99, but not with the other languages?
-
-At the end, we should have a simple macro, such as AC_LANG_COMPILER
-for instance, which is built over simpler macros. Each language
-support should come with these simpler macros, but each language
-should follow the same process.
-
-We also need to check the srcext which are supported by the compiler.
-In fact, this macro is also probably the right place to check for
-objext and exeext.
-
-** AC_PROG_CC_STDC
-Should be: AC_PROG_CC_ISO? Or even more specific for the ISO version?
-Should include more tests (e.g., AC_C_CONST etc.)?
-
-** AC_SYS_INTERPRETER
-Defines $interpval. This is not a standard name. Do we want to keep
-this? Clarify our policy on those names.
-
-** autoupdate
-We should probably install the files which do not depend upon the
-user, just the Autoconf library files. But conversely autoupdate must
-be opened to user macros, i.e., for instance libtool itself must be
-able to say that AM_PROG_LIBTOOL is now AC_PROG_LIBTOOL, and have
-autoupdate do its job on old configure.in.
-
-** AC_LIBOBJ_DECL
-Decide with the Automake team whether this macro should list only `.c'
-files, or it should include the `.h' too. For instance the
-AC_FUNC_GNU_GETOPT macro could provide the three files, likewise for
-the macro which allows to choose a regex engine.
-
-** Allow --recursive to config.status
-So that --recheck does not pass --no-recursive to configure.
-
-** AC_PROG_CC_STDC
-Well, back onto this one :( See Peter for very useful comments on the
-technology. Should we make this a new language? AC_LANG(ISO C). It
-would be great to introduce AC_LANG_COMPILER in this release too.
-
-* autoconf.texi
-Move the specific macro documentation blocks into the source files,
-and use a doc-block extraction/merge technique to get docuemntation
-into texi-file. This should help avoid bit-rot in the doc, and make
-the doc easier to update when people add/change macros. The name
-"autodoc" is probably already taken so we probably need another one.
-
-------------------------------------------------------------------------------
-
-* Automake
-
-** missing.m4
-The test for a recent missing doesn't hide the error messages from the
-old missing.
-
-** AU_DEFUN
-The section for old macros is not completely up to date. For
-instance, there is still AM_PROG_LIBTOOL. Anyway, since autoupdate
-takes care of them, it is no longer the role of Automake to handle
-this. Most should be removed.
-
-** AC_EXEXT, AC_OBJEXT
-Support should be enabled by default.
-
-** Macros now swallowed by Autoconf.
-error.m4, obstack.m4, ptrdiff.m4, strtod.m4, termios.m4, winsz.m4.
-
-------------------------------------------------------------------------------
-
-* m4
-
-** I18n
-The error messages for indir and dumpdef are uselessly different. Fix
-this for translators.
-
-** Tracing `builtin'
-F**k! --trace FOO does not catch indir([FOO], $@)!
-
-** Tracing builtins
-GNU M4 1.4's tracing of builtins is buggy. When run on this input:
-
-| divert(-1)
-| changequote([, ])
-| define([m4_eval], defn([eval]))
-| eval(1)
-| m4_eval(2)
-| undefine([eval])
-| m4_eval(3)
-
-it behaves this way:
-
-| % m4 input.m4 -da -t eval
-| m4trace: -1- eval(1)
-| m4trace: -1- m4_eval(2)
-| m4trace: -1- m4_eval(3)
-| %
-
-Conversely:
-
-| % m4 input.m4 -da -t m4_eval
-| %
-
-------------------------------------------------------------------------------
-
-* Autoconf 3
-
-** Cache name spaces.
-Cf the discussion with Kaveh. One would like to
-AC_CHECK_FUNCS(bar)
-# Do something that changes the environment
-AC_CACHE_PUSH(foo)
-AC_CHECK_FUNCS(bar)
-AC_CACHE_POP
-in order not to erase the results of a check with another.
-
-** Cache var names
-should depend upon the current language.
-
-** Use m4 lists?
-I think one sad decision in Autoconf was to use white space separated
-lists for some arguments. For instance AC_CHECK_FUNCS(foo bar). I
-tend to think that, even if it is not as nice, we should use m4 lists,
-i.e., AC_CHECK_FUNCS((foo, bar)) in this case. This would ease
-specializing loops, and more importantly, make them much more robust.
-
-A typical example of things that can be performed if we use m4 lists
-instead of white space separated lists is the case of things that have
-a space in their names, eg, structures.
-
-With the current scheme it would be extremely difficult to loop over
-AC_CHECK_STRUCTS(struct foo struct bar), while it natural and well
-defined for m4 lists: AC_CHECK_STRUCTS((struct foo, struct bar)).
-
-I know that makes a huge difference in syntax, but a major release
-should be ready to settle a new world. We *can* provide helping tools
-for the transition. Considering the benefits, I really think it is
-worth thinking. --akim
-
-** Forbid shell variables as main arguments
-The fact that we have to support shell variables as main argument
-forbids many interesting constructions (specialization are not always
-possible, equally for AC_REQUIRE'ing macros *with their arguments*).
-Any loop should be handled by m4 itself, and nothing should be hidden
-to it. As a consequence, shell variables on the main arguments become
-useless (the main reason we support shell variables is to allow the
-loop versions of single argument macros, eg, to go from AC_CHECK_FUNC
-to AC_CHECK_FUNCS). --akim
-
-** Use the @SUBST@ technology also for headers instead of #undef.
-This requires that acconfig.h becomes completely obsolete: autoheader
-should generate all the templates.
-
-** Specializing loops.
-For instance, make AC_CHECK_FUNC[S] automatically use any particular
-macros for the listed functions.
-This requires to obsolete the feature `break' in ACTION-IF, since all
-the loops are to be handled by m4, not sh.
-
-** Faces of a test
-Each macro can potentially come with several faces: of course the
-configure snippet (AC_foo), a config.h snippet (AH_foo), a system.h
-snippet (AS_foo), documentation (AD_foo) and, why not, the some C code
-for instance to replace a function.
-
-The motivation for the `faces' is to encapsulate. It is abnormal that
-once one has a configure macro, then she has to read somewhere to find
-the piece of system.h to use etc. The macros should come in a
-self-contained way, or, said it another way, PnP.
-
-A major issue is that of specialization. AC_CHECK_HEADER (or another
-name) for instance, will have as an effect, via system.h to include
-the header. But if the test for the header is specific, the generic
-AS_CHECK_HEADER will still be used. Conversely, some headers may not
-require a specific AC_ tests, but a specialized AS_ macro.
-
-------------------------------------------------------------------------------
-
-* Make AC_CHECK_LIB check whether the function is already available
- before checking for the library. This might involve adding another
- kind of cache variable to indicate whether a given function needs a
- given library. The current ac_cv_func_ variables are intended to
- indicate whether the function is in the default libraries, but
- actually also take into account whatever value LIBS had when they
- were checked for.
-
- Isn't this the issue of AC_SEARCH_LIB? --akim
- How come the list of libraries to browse not an additional parameter
- of AC_CHECK_FUNC, exactly like for the headers? --akim
-
-------------------------------------------------------------------------------
-
-* Add AC_PROG_CC_POSIX to replace the current ad-hoc macros for AIX,
- Minix, ISC, etc.
-
-------------------------------------------------------------------------------
-
-* Support creating both config.h and DEFS in the same configure.
-
-------------------------------------------------------------------------------
-
-* Select the right CONFIG_SHELL automatically (for Ultrix, Lynx especially.)
-
-------------------------------------------------------------------------------
-
-* Doc: Centralize information on POSIX, MS-DOS, cross-compiling, and
- other important topics.
-
-------------------------------------------------------------------------------
-
-* Mike Haertel's suggestions:
-
-** Provide header files containing decls for alloca, strings, etc.
-
-** Cross compiling:
-
-*** Error messages include instructions for overriding defaults using
-config.site.
-
-*** Distribute a config.site corresponding to a hypothetical bare POSIX system with c89.
-
-** Site defaults:
-
-*** Convention for consistency checking of env vars and options in config.site so config.site can print obnoxious messages if it doesn't like options or env vars that users use.
-
-------------------------------------------------------------------------------
-
-* Look at user contributed macros:
- IEEE double precision math
- more
-
-------------------------------------------------------------------------------
-
-For AC_TYPE_SIGNAL signal handlers, provide a way for code to know
-whether to do "return 0" or "return" (int vs void) to avoid compiler
-warnings. (Roland McGrath)
-
-------------------------------------------------------------------------------
-
-In config.status comment, put the host/target/build types, if used.
-
-------------------------------------------------------------------------------
-
-on hal.gnu.ai.mit.edu, configure is getting the wrong answer for
-AC_CHECK_FUNCS(select).
-
-The problem here is that there's severe name space pollution: when
-conftest.c includes <ctype.h> to pick up any __stub macro definitions,
-it's getting a prototype declaration for select(), which collides
-with the dummy declaration in conftest.c. (The chain of includes
-is conftest.c -> <ctype.h> -> <sys/localedef.h> -> <sys/lc_core.h>
--> <sys/types.h> -> <sys/select.h>.)
-
- #define $ac_func __dummy_$ac_func
- #include <ctype.h>
- #undef $ac_func
-From: kwzh@gnu.ai.mit.edu (Karl Heuer)
-
-The test for the isascii function was failing because that function is
-also a macro. He proposed that the test file look like this:
-
-/* Remove any macro definition. */
-#undef isascii
-/* Override any gcc2 internal prototype to avoid an error. */
-char isascii(); isascii();
-
-Andreas Schwab
-
-------------------------------------------------------------------------------
-
-It would be nice if I could (in the Makefile.in files) set
-the path to config.h. You have config.h ../config.h ../../config.h's all
-over the place, in the findutils-4.1 directory.
-From: "Randall S. Winchester" <rsw@eng.umd.edu>
-
-------------------------------------------------------------------------------
-
-In a future version (after 2.2), make AC_PROG_{CC,RANLIB,anything else}
-use AC_CHECK_TOOL.
-From Roland McGrath.
-
-------------------------------------------------------------------------------
-
- ls -lt configure configure.in | sort
-doesn't work right if configure.in is from a symlink farm, where the
-symlink has either a timestamp of its own, or under BSD 4.4, it has
-the timestamp of the current directory, neither of which
-helps. Changing it to
- ls -Llt configure configure.in | sort
-works for me, though I don't know how portable that is
-_Mark_ <eichin@cygnus.com>

-------------------------------------------------------------------------------
-
-Here is the thing I would like the most;
-AC_PKG_WITH(PACKAGE, HELP_STRING, PACKAGE-ROOT, PACKAGE-LIBS, PACKAGE-DEFS,
- PACKAGE-CCPFLAGS)
-like
-
-AC_PKG_WITH(kerberos,,/usr/local/athena,-lkrb -ldes,[KERBEROS KRB4
-CRYPT],include)
-AC_PKG_WITH(hesiod,
-[if hesiod is not in kerberos-root add --with-hesiod-root=somewhere]
-,,-lhesiod,HESIOD,,)
-AC_PKG_WITH(glue,,,-lglue,GLUE,,)
-AC_PKG_WITH(bind,,/usr/local/bind, [lib/resolv.a lib/lib44bsd.a], ,include)
-After the apropriate checks, the existance of the paths, and libs and such
-LIBS=$LIBS $PKG-LIBS
-DEFS=$DEFS $PKG-DEFS
-CPPFLAGS=$PKG-CPPFLAGS $CPPFLAGS
-$PKG-ROOT=$PKG-ROOT
-The cppflags should reverse the order so that you can have;
--I/usr/local/bind/include -I/usr/local/athena/include
-and
--L/usr/local/athena/lib -lkrb -ldes /usr/local/bind/lib/libresolv.a
-as order matters.
-
-also an AC_PKG_CHK_HEADER
-and an AC_PKG_CHK_FUNCTION
-so one can give alternate paths to check for stuff ($PKG-ROOT/lib for
-example)
-From: Randall Winchester
-
-------------------------------------------------------------------------------
-
-AC_C_CROSS assumes that configure was called like 'CC=target-gcc;
-./configure'. I want to write a package that has target dependent
-libraries and host dependent tools. So I don't like to lose the
-distinction between CC and [G]CC_FOR_TARGET. AC_C_CROSS should check
-for equality of target and host.
-
-It would be great if
-
-GCC_FOR_TARGET
-AR_FOR_TARGET
-RANLIB_FOR_TARGET
-
-would be set automatically if host != target.
-AC_LANG_CROSS_C would be nice too, to check header files
-etc. with GCC_FOR_TARGET instead of CC
-
-Here is one simple test
-
-if test "x$host" != "x$target"; then
-AC_PROGRAMS_CHECK(AR_FOR_TARGET, $target-ar, $target-ar, ar)
-AC_PROGRAMS_CHECK(RANLIB_FOR_TARGET, $target-ranlib, $target-ranlib, ranlib)
-AC_PROGRAMS_CHECK(GCC_FOR_TARGET, $target-gcc, $target-gcc, gcc)
-fi
-
-This could be improved to also look for gcc in PATH, but require the
-prefix to contain the target e.g.:
-
-target=m68k-coff -->GCC_FOR_TARGET = /usr/gnu/m68k-coff/bin/gcc
-
-From: nennker@cs.tu-berlin.DE (Axel Nennker)
-
-------------------------------------------------------------------------------
-
-The problem occurs with the following libc functions in SunOS 5.4:
-
- fnmatch glob globfree regcomp regexec regerror regfree wordexp wordfree
-
-It also occurs with a bunch more libposix4 functions that most people
-probably aren't worried about yet, e.g. shm_open.
-
-All these functions fail with errno set to ENOSYS (89)
-``Operation not applicable''.
-
-Perhaps Autoconf should have a specific macro for fnmatch, another for
-glob+globfree, another for regcomp+regexec+regerror+regfree, and
-another for wordexp+wordfree. This wouldn't solve the problem in
-general, but it should work for Solaris 2.4. Or Autoconf could limit
-itself to fnmatch and regcomp, the only two functions that I know have
-been a problem so far.
-
-From Paul Eggert.
-
-------------------------------------------------------------------------------
-
-Make easy macros for checking for X functions and libraries, such as Motif.
-
-------------------------------------------------------------------------------
-
-There are basically three ways to lock files
- lockf, fnctl, flock
-I'd be interested in adding a macro to pick the "right one" if you're
-interested.
-
-From: Rich Salz <rsalz@osf.org>
-
-------------------------------------------------------------------------------
-
-Timezone calculations checks.
-
-------------------------------------------------------------------------------
-
-Support different default filesystem layouts, e.g. SVR4, Linux.
-Of course, this can be done locally with config.site.
-
-------------------------------------------------------------------------------
-
-I wonder if it is possible to get the path for X11's app-defaults
-directory by autoconf. Moreover, I'd like to have a general way of
-accessing imake variables by autoconf, something like
-
-AC_DEFINE(WINE_APP_DEFAULTS, AC_IMAKE_VAR(XAPPLOADDIR))
-

-
-Cache consistency checking: ignore cache if environment
-(CC or PATH) differs.
-From Mike Haertel
-
-So we need a general mechanism for storing variables' values in the cache,
-and checking if they are the same after reading the cache. Then we can add
-to the list of variables as we come across the need. So far we want
-LD_LIBRARY_PATH and the internal variables for some of (all?) the args.
-From: roland@gnu.ai.mit.edu (Roland McGrath)
-
-Hmm. That list might include LD_LIBRARY_PATH, LD_RUN_PATH (for solaris),
-and PATH. I can't think of any others so far.
-From: friedman@splode.com (Noah Friedman)
-
-------------------------------------------------------------------------------
-
-Every user running X11 usually has a directory like *X11* in his PATH
-variable. By replacing bin by include, you can find good places to
-look for the include files or libraries.
-
-From: rcb5@win.tue.nl (Richard Verhoeven)
-
-------------------------------------------------------------------------------
-
-In most cases, when autoscan suggests something, using the search or
-index command into the Info reader for autoconf manual quickly
-explains me what the test is about. However, for header files and
-functions, the search might fail, because the test is not of the
-specific kind. The Autoconf manual should reflect somewhere all
-header files or functions (non-specific features, generally)
-triggering autoscan to generate tests, and tell in a few words what is
-the problem, and the suggested approach for a solution; that is, how
-one should use the result of testing the feature.
-
-From: pinard@iro.umontreal.ca
-
-------------------------------------------------------------------------------
-
-It would be nice if the configure script would handle an option such as
---x-libraries="/usr/openwin/lib /usr/dt/lib".
-
-Rick Boykin <rboykin@cscsun3.larc.nasa.gov>
-
-Under Solaris 2.4, the regular X includes and libs and the Motif
-includes and libs are in different places. The Emacs configure script
-actually allows dir1:dir2:dir3 --
-
- if test "${x_libraries}" != NONE && test -n "${x_libraries}"; then
- LD_SWITCH_X_SITE=-L`echo ${x_libraries} | sed -e "s/:/ -L/g"`
- LD_SWITCH_X_SITE_AUX=-R`echo ${x_libraries} | sed -e "s/:/ -R/g"`
- fi
- if test "${x_includes}" != NONE && test -n "${x_includes}"; then
- C_SWITCH_X_SITE=-I`echo ${x_includes} | sed -e "s/:/ -I/g"`
- fi
-
-------------------------------------------------------------------------------
-
- What messages should be produced by default, if any?
-
-Probably only the few most important ones, like which configuration
-name was used, whether X or Xt are in use, etc. The specific
-decisions, and progress messages, should be recorded on the terminal
-only if --verbose is used.
-
- --silent just supresses the "checking for...result"
- messages, not the "creating FOO" messages.
-
-I think the default should be to suppress both.
-From: Richard Stallman <rms@gnu.ai.mit.edu>
-
-There is no distinction now between
-important decisions (we have X) vs minor decisions (we have lstat).
-However, there are probably only a few things you deem important enough to
-announce and only those few things will need to be changed.
-Perhaps config.status could be written with comments saying what was
-decided.
-From: Roland McGrath <roland@gnu.ai.mit.edu>
-
-------------------------------------------------------------------------------
-
-Another thing I wish for is a macro which figures out which libraries are
-needed for BSD-sytle sockets. AC_PATH_X already detects this
-correctly...so it's just a matter of seperating out the socket-related code.
-From: "Joel N. Weber II" <nemo@koa.iolani.honolulu.hi.us>
-
-------------------------------------------------------------------------------
-
-in order to use the AC_CANONICAL_SYSTEM macro, I have to have
-install-sh somewhere nearby --- why is this? I have no real reason to
-distribute install-sh, other than that its absence breaks this code.
-
-Shouldn't the above loop be looking for config.sub and config.guess?
-From: jimb@totoro.bio.indiana.edu (Jim Blandy)
-
-adding AC_CANONICAL_HOST to my configure.in script caused
-all sorts of odd/unexplained errors. Obviously, I had to go
-get copies of config.guess, config.sub and install-sh from the
-autoconf distribution, but the error messages and autoconf docs
-didn't explain that very well.
-From: bostic@bsdi.com (Keith Bostic)
-
-------------------------------------------------------------------------------
-
-Perhaps also have AC_TRY_COMPILER try to link an invalid program, and
-die if the compiler seemed to succeed--in which case it's not usable
-with autoconf scripts.
-
-------------------------------------------------------------------------------
-
-autoreconf doesn't support having (in the same tree) both directories
-that are parts of a larger package (sharing aclocal.m4 and
-acconfig.h), and directories that are independent packages (each with
-their own ac*). It assumes that they are all part of the same
-package, if you use --localdir, or that each directory is a separate
-package, if you don't use it.
-
-autoreconf should automatically figure out which ac* files to use--the
-closest ones up the tree from each directory, probably, unless
-overridden by --localdir.
-
-Also, autoreconf recurses on all subdirectories containing a
-configure.in, not just those given by an AC_CONFIG_SUBDIRS directive.
-This may not be a problem in practice.

-# AC_HELP_STRING(LHS, RHS, [COLUMN])
-# ----------------------------------
-#
-# Format an Autoconf macro's help string so that it looks pretty when
-# the user executes "configure --help". This macro takes three
-# arguments, a "left hand side" (LHS), a "right hand side" (RHS), and
-# the COLUMN which is a string of white spaces which leads to the
-# the RHS column (default: 26 white spaces).
-#
-# The resulting string is suitable for use in other macros that require
-# a help string (e.g. AC_ARG_WITH).
-#
-# Here is the sample string from the Autoconf manual (Node: External
-# Software) which shows the proper spacing for help strings.
-#
-# --with-readline support fancy command line editing
-# ^ ^ ^
-# | | |
-# | column 2 column 26
-# |
-# column 0
-#
-# A help string is made up of a "left hand side" (LHS) and a "right
-# hand side" (RHS). In the example above, the LHS is
-# "--with-readline", while the RHS is "support fancy command line
-# editing".
-#
-# If the LHS extends past column 24, then the LHS is terminated with a
-# newline so that the RHS is on a line of its own beginning in column
-# 26.
-#
-# Therefore, if the LHS were instead "--with-readline-blah-blah-blah",
-# then the AC_HELP_STRING macro would expand into:
-#
-#
-# --with-readline-blah-blah-blah
-# ^ ^ support fancy command line editing
-# | | ^
-# | column 2 |
-# column 0 column 26

-
-
-# This section handles about all the preparation aspects for
-# `config.status': registering the configuration files, the headers,
-# the links, and the commands `config.status' will run. There is a
-# little mixture though of things actually handled by `configure',
-# such as running the `configure' in the sub directories. Minor
-# detail.
-#
-# There are two kinds of commands:
-#
-# COMMANDS:
-#
-# They are output into `config.status' via a quoted here doc. These
-# commands are always associated to a tag which the user can use to
-# tell `config.status' what are the commands she wants to run.
-#
-# INIT-CMDS:
-#
-# They are output via an *unquoted* here-doc. As a consequence $var
-# will be output as the value of VAR. This is typically used by
-# `configure' to give `config,.status' some variables it needs to run
-# the COMMANDS. At the difference of `COMMANDS', the INIT-CMDS are
-# always run.
-#
-#
-# Some uniformity exists around here, please respect it!
-#
-# A macro named AC_CONFIG_FOOS has three args: the `TAG...' (or
-# `FILE...' when it applies), the `COMMANDS' and the `INIT-CMDS'. It
-# first checks that TAG was not registered elsewhere thanks to
-# AC_CONFIG_UNIQUE. Then it registers `TAG...' in AC_LIST_FOOS, and for
-# each `TAG', a special line in AC_LIST_FOOS_COMMANDS which is used in
-# `config.status' like this:
-#
-# case $ac_tag in
-# AC_LIST_FOOS_COMMANDS
-# esac
-#
-# Finally, the `INIT-CMDS' are dumped into a special diversion, via
-# `_AC_CONFIG_COMMANDS_INIT'. While `COMMANDS' are output once per TAG,
-# `INIT-CMDS' are dumped only once per call to AC_CONFIG_FOOS.
-#
-# It also leave the TAG in the shell variable ac_config_foo which contains
-# those which will actually be executed. In other words:
-#
-# if false; then
-# AC_CONFIG_FOOS(bar, [touch bar])
-# fi
-#
-# will not create bar.
-#
-# AC_CONFIG_FOOS can be called several times (with different TAGs of
-# course).
-#
-# Because these macros should not output anything, there should be `dnl'
-# everywhere. A pain my friend, a pain. So instead in each macro we
-# divert(-1) and restore the diversion at the end.
-#
-#
-# Honorable members of this family are AC_CONFIG_FILES,
-# AC_CONFIG_HEADERS, AC_CONFIG_LINKS and AC_CONFIG_COMMANDS. Bad boys
-# are AC_LINK_FILES, AC_OUTPUT_COMMANDS and AC_OUTPUT when used with
-# arguments. False members are AC_CONFIG_SRCDIR, AC_CONFIG_SUBDIRS

-# The code produced used to be extremely costly: there are was a

-# `#undef' templates with trailing space, and `#undef' templates
-# without trailing spaces. The full script was run on each of the m
-# lines of `config.h.in', i.e., about n x m.
-#
-# Now there are two scripts: `conftest.defines' for the `#define'
-# templates, and `conftest.undef' for the `#undef' templates.
-#
-# Optimization 1. It is incredibly costly to run two `#undef'
-# scripts, so just remove trailing spaces first. Removes about a
-# third of the cost.
-#
-# Optimization 2. Since `#define' are rare and obsoleted,
-# `conftest.defines' is built and run only if grep says there are
-# `#define'. Improves by at least a factor 2, since in addition we
-# avoid the cost of *producing* the sed script.
-#
-# Optimization 3. In each script, first check that the current input
-# line is a template. This avoids running the full sed script on
-# empty lines and comments (divides the cost by about 3 since each
-# template chunk is typically a comment, a template, an empty line).
-#
-# Optimization 4. Once a substitution performed, since there can be
-# only one per line, immediately restart the script on the next input
-# line (using the `t' sed instruction). Divides by about 2.
-# *Note:* In the case of the AC_SUBST sed script (_AC_OUTPUT_FILES)
-# this optimization cannot be applied as is, because there can be

-#
-# This macro is intended to be used in those situations when it is
-# necessary to mix, e.g. C++ and Fortran 77, source code into a single
-# program or shared library.
-#
-# For example, if object files from a C++ and Fortran 77 compiler must
-# be linked together, then the C++ compiler/linker must be used for
-# linking (since special C++-ish things need to happen at link time
-# like calling global constructors, instantiating templates, enabling
-# exception support, etc.).
-#
-# However, the Fortran 77 intrinsic and run-time libraries must be
-# linked in as well, but the C++ compiler/linker doesn't know how to
-# add these Fortran 77 libraries. Hence, the macro
-# "AC_F77_LIBRARY_LDFLAGS" was created to determine these Fortran 77
-# libraries.
-#
-# This macro was packaged in its current form by Matthew D. Langston.
-# However, nearly all of this macro came from the "OCTAVE_FLIBS" macro
-# in "octave-2.0.13/aclocal.m4", and full credit should go to John

-# General checks. #
-# ---------------- #
-
-# Up to 2.13 included, Autoconf used to provide the macro
-#
-# AC_CHECK_TYPE(TYPE, DEFAULT)
-#
-# Since, it provides another version which fits better with the other
-# AC_CHECK_ families:
-#
-# AC_CHECK_TYPE(TYPE,
-# [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND],
-# [INCLUDES])
-#
-# In order to provide backward compatibility, the new scheme is
-# implemented as _AC_CHECK_TYPE_NEW, the old scheme as _AC_CHECK_TYPE_OLD,
-# and AC_CHECK_TYPE branches to one or the other, depending upon its
-# arguments.
-
-
-
-# _AC_CHECK_TYPE_NEW(TYPE,
-# [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND],
-# [INCLUDES])
-# ------------------------------------------------------------
-# Check whether the type TYPE is supported by the system, maybe via the
-# the provided includes. This macro implements the former task of
-# AC_CHECK_TYPE, with one big difference though: AC_CHECK_TYPE was
-# grepping in the headers, which, BTW, led to many problems until
-# the egrep expression was correct and did not given false positives.
-# It turned out there are even portability issues with egrep...
-#
-# The most obvious way to check for a TYPE is just to compile a variable
-# definition:
-#
-# TYPE my_var;
-#
-# Unfortunately this does not work for const qualified types in C++,
-# where you need an initializer. So you think of
-#
-# TYPE my_var = (TYPE) 0;
-#
-# Unfortunately, again, this is not valid for some C++ classes.
-#
-# Then you look for another scheme. For instance you think of declaring
-# a function which uses a parameter of type TYPE:
-#
-# int foo (TYPE param);
-#
-# but of course you soon realize this does not make it with K&R
-# compilers. And by no ways you want to
-#
-# int foo (param)
-# TYPE param
-# { ; }
-#
-# since this time it's C++ who is not happy.
-#
-# Don't even think of the return type of a function, since K&R cries
-# there too. So you start thinking of declaring a *pointer* to this TYPE:
-#
-# TYPE *p;
-#
-# but you know fairly well that this is legal in C for aggregates which
-# are unknown (TYPE = struct does-not-exist).
-#
-# Then you think of using sizeof to make sure the TYPE is really
-# defined:
-#
-# sizeof (TYPE);
-#
-# But this succeeds if TYPE is a variable: you get the size of the
-# variable's type!!!
-#
-# This time you tell yourself the last two options *together* will make
-# it. And indeed this is the solution invented by Alexandre Oliva.
-#
-# Also note that we use
-#
-# if (sizeof (TYPE))
-#
-# to `read' sizeof (to avoid warnings), while not depending on its type
-# (not necessarily size_t etc.). Equally, instead of defining an unused
-# variable, we just use a cast to avoid warnings from the compiler.
-# Suggested by Paul Eggert.

-Usage: $0 [OPTION] ... [TEMPLATE-FILE]
-
-Generate a configuration script from a TEMPLATE-FILE if given, or
-\`configure.ac' if present, or else \`configure.in'. Output is sent
-to the standard output if TEMPLATE-FILE is given, else into
-\`configure'.
-
-Operation modes:
- -h, --help print this help, then exit
- -V, --version print version number, then exit
- -v, --verbose verbosely report processing
- -d, --debug don't remove temporary files
- -o, --output=FILE save output in FILE (stdout is the default)
- -W, --warnings=CATEGORY report the warnings falling in CATEGORY [syntax]
-
-Warning categories include:
- \`cross' cross compilation issues
- \`obsolete' obsolete constructs
- \`syntax' dubious syntactic constructs
- \`all' all the warnings
- \`no-CATEGORY' turn off the warnings on CATEGORY
- \`none' turn off all the warnings
- \`error' warnings are error
-
-The environment variable \`WARNINGS' is honored.
-
-Library directories:
- -A, --autoconf-dir=ACDIR Autoconf's macro files location (rarely needed)
- -l, --localdir=DIR location of the \`aclocal.m4' file
-
-Tracing:
- -t, --trace=MACRO report the list of calls to MACRO
- -i, --initialization also trace Autoconf's initialization process
-
-In tracing mode, no configuration script is created.
-
-Report bugs to <bug-autoconf@gnu.org>."

-# ## ---------------------------- ##
-# ## How `autoupdate' functions. ##
-# ## ---------------------------- ##
-#
-# The task of `autoupdate' is not trivial: the biggest difficulty being
-# that you must limit the changes to the parts that really need to be
-# updated. Finding a satisfying implementation proved to be quite hard,
-# as this is the fourth implementation of `autoupdate'.
-#
-# Below, we will use a simple example of obsolete macro:
-#
-# AU_DEFUN([OLD], [NEW([$1, $2], m4_eval([$1 + $2]))])
-# AC_DEFUN([NEW], [echo "sum($1) = $2"])
-#
-# the input file contains
-#
-# dnl The Unbelievable Truth
-# OLD(1, 2)
-# NEW([0, 0], [0])
-#
-# Of course the expected output is
-#
-# dnl The Unbelievable Truth
-# NEW([1, 2], [3])
-# NEW([0, 0], [0])
-#
-#
-# # First implementation: sed
-# # =========================
-#
-# The first implementation was only able to change the name of obsolete
-# macros.
-#
-# The file `acoldnames.m4' defined the old names based on the new names.
-# It was simple then to produce a sed script such as:
-#
-# s/OLD/NEW/g
-#
-# Updating merely consisted in running this script on the file to
-# update.
-#
-# This scheme suffers an obvious limitation: that `autoupdate' was
-# unable to cope with new macros that just swap some of its arguments
-# compared to the old macro. Fortunately, that was enough to upgrade
-# from Autoconf 1 to Autoconf 2. (But I have no idea whether the
-# changes in Autoconf 2 were precisely limited by this constraint.)
-#
-#
-# # Second implementation: hooks
-# # ============================
-#
-# The version 2.15 of Autoconf brought a vast number of changes compared
-# to 2.13, so a solution was needed. One could think to extend the
-# `sed' scripts with specialized code for complex macros. But this
-# approach is of course full of flaws:
-#
-# a. the Autoconf maintainers have to write these snippets, which we
-# just don't want to,
-#
-# b. I really don't think you'll ever manage to handle the quoting of
-# m4 from sed.
-#
-# To satisfy a., let's remark that the code which implements the old
-# features in term of the new feature is exactly the code which should
-# replace the old code.
-#
-# To answer point b, as usual in the history of Autoconf, the answer, at
-# least on the paper, is simple: m4 is the best tool to parse m4, so
-# let's use m4.
-#
-# Therefore the specification is:
-#
-# I want to be able to tell Autoconf, well, m4, that the macro I
-# am currently defining is an obsolete macro (so that the user is
-# warned), which code is the code to use when running autoconf,
-# but that the very same code has to be used when running
-# autoupdate. To summarize, the interface I want is
-# `AU_DEFUN(OLD-NAME, NEW-CODE)'.
-#
-#
-# Now for the technical details.
-#
-# When running autoconf, except for the warning, AU_DEFUN is basically
-# AC_DEFUN.
-#
-# When running autoupdate, we want *only* OLD-NAMEs to be expanded.
-# This obviously means that acgeneral.m4 and acspecific.m4 must not be
-# loaded. Nonetheless, because we want to use a rich set of m4
-# features, m4sugar.m4 is needed. Please note that the fact that
-# Autoconf's macros are not loaded is positive on two points:
-#
-# - we do get an updated `configure.ac', not a `configure'!
-#
-# - the old macros are replaced by *calls* to the new-macros, not the
-# body of the new macros, since their body is not defined!!!
-# (Whoa, that's really beautiful!).
-#
-# Additionally we need to disable the quotes when reading the input for
-# two reasons: first because otherwise `m4' will swallow the quotes of
-# other macros:
-#
-# NEW([1, 2], 3)
-# => NEW(1, 2, 3)
-#
-# and second, because we want to update the macro calls which are
-# quoted, i.e., we want
-#
-# FOO([OLD(1, 2)])
-# => FOO([NEW([1, 2], [3])])
-#
-# If we don't disable the quotes, only the macros called at the top
-# level would be updated.
-#
-# So, let's disable the quotes.
-#
-# Well, not quite: m4sugar.m4 still needs to use quotes for some macros.
-# Well, in this case, when running in autoupdate code, each macro first
-# reestablishes the quotes, expands itself, and disables the quotes.
-#
-# Thinking a bit more, you realize that in fact, people may use `define'
-# `ifelse' etc. in their files, and you certainly don't want to process
-# them. Another example is `dnl': you don't want to remove the
-# comments. You then realize you don't want exactly to import m4sugar:
-# you want to specify when it is enabled (macros active), and disabled.
-# m4sugar provides m4_disable/m4_enable to this end.
-#
-# You're getting close to it. Now remains one task: how to handle
-# twofold definitions?
-#
-# Remember that the same AU_DEFUN must be understood in two different
-# ways, the AC way, and the AU way.
-#
-# One first solution is to check whether acgeneral.m4 was loaded. But
-# that's definitely not cute. Another is simply to install `hooks',
-# that is to say, to keep in some place m4 knows, late `define' to be
-# triggered *only* in AU mode.
-#
-# You first think to design AU_DEFUN like this:
-#
-# 1. AC_DEFUN(OLD-NAME,
-# [Warn the user OLD-NAME is obsolete.
-# NEW-CODE])
-#
-# 2. Store for late AU binding([define(OLD_NAME,
-# [Reestablish the quotes.
-# NEW-CODE
-# Disable the quotes.])])
-#
-# but this will not work: NEW-CODE has probably $1, $2 etc. and these
-# guys will be replaced with the argument of `Store for late AU binding'
-# when you call it.
-#
-# I don't think there is a means to avoid this using this technology
-# (remember that $1 etc. are *always* expanded in m4). You may also try
-# to replace them with $[1] to preserve them for a later evaluation, but
-# if `Store for late AU binding' is properly written, it will remain
-# quoted till the end...
-#
-# You have to change technology. Since the problem is that `$1'
-# etc. should be `consumed' right away, one solution is to define now a
-# second macro, `AU_OLD-NAME', and to install a hook than binds OLD-NAME
-# to AU_OLD-NAME. Then, autoupdate.m4 just need to run the hooks. By
-# the way, the same method was used in autoheader.
-#
-#
-# # Third implementation: m4 namespaces by m4sugar
-# # ==============================================
-#
-# Actually, this implementation was just a clean up of the previous
-# implementation: instead of defining hooks by hand, m4sugar was equipped
-# with `namespaces'. What are they?
-#
-# Sometimes we want to disable some *set* of macros, and restore them
-# later. We provide support for this via namespaces.
-#
-# There are basically three characters playing this scene: defining a
-# macro in a namespace, disabling a namespace, and restoring a namespace
-# (i.e., all the definitions it holds).
-#
-# Technically, to define a MACRO in NAMESPACE means to define the macro
-# named `NAMESPACE::MACRO' to the VALUE. At the same time, we append
-# `undefine(NAME)' in the macro named `m4_disable(NAMESPACE)', and
-# similarly a binding of NAME to the value of `NAMESPACE::MACRO' in
-# `m4_enable(NAMESPACE)'. These mechanisms allow to bind the macro of
-# NAMESPACE and to unbind them at will.
-#
-# Of course this implementation is really inefficient: m4 has to grow
-# strings which can become quickly huge, which slows it significantly.
-#
-# In particular one should avoid as much as possible to use `define' for
-# temporaries. Now that `define' as quite a complex meaning, it is an
-# expensive operations that should be limited to macros. Use
-# `m4_define' for temporaries.
-#
-# Private copies of the macros we used in entering / exiting the m4sugar
-# namespace. It is much more convenient than fighting with the renamed
-# version of define etc.
-#
-#
-#
-# Those two implementations suffered from serious problems:
-#
-# - namespaces were really expensive, and incurred a major performance
-# loss on `autoconf' itself, not only `autoupdate'. One solution
-# would have been the limit the use of namespaces to `autoupdate', but
-# that's again some complications on m4sugar, which really doesn't need
-# this. So we wanted to get rid of the namespaces.
-#
-# - since the quotes were disabled, autoupdate was sometimes making
-# wrong guesses, for instance on:
-#
-# foo([1, 2])
-#
-# m4 saw 2 arguments: `[1'and `2]'. A simple solution, somewhat
-# fragile, is to reestablish the quotes right before all the obsolete
-# macros, i.e., to use sed so that the previous text becomes
-#
-# changequote([, ])foo([1, 2])
-#
-# To this end, one wants to trace the definition of obsolete macros.
-#
-# It was there that the limitations of the namespace approach became
-# painful: because it was a complex machinery playing a lot with the
-# builtins of m4 (hence, quite fragile), tracing was almost impossible.
-#
-#
-# So this approach was dropped.
-#
-#
-# # The fourth implementation: two steps
-# # ====================================
-#
-# If you drop the uses of namespaces, you no longer can compute the
-# updated value, and replace the old call with it simultaneously.
-#
-# Obviously you will use m4 to compute the updated values, but you may
-# use some other tool to achieve the replacement. Personally, I trust
-# nobody but m4 to parse m4, so below, m4 will perform the two tasks.
-#
-# How can m4 be used to replace *some* macros calls with newer values.
-# Well, that's dead simple: m4 should learn the definitions of obsolete
-# macros, forget its builtins, disable the quotes, and then run on the
-# input file, which amounts to doing this:
-#
-# divert(-1)dnl
-# changequote([, ])
-# define([OLD], [NEW([$1, $2], m4_eval([$1 + $2]))changequote()])
-# undefine([dnl])
-# undefine([m4_eval])
-# # Some more undefines...
-# changequote()
-# divert(0)dnl
-# dnl The Unbelievable Truth
-# changequote([, ])OLD(1, 2)
-# NEW([0, 0],
-# 0)
-#
-# which will result in
-#
-# dnl The Unbelievable Truth
-# NEW(1, 2, m4_eval(1 + 2))
-# NEW([0, 0],
-# 0)
-#
-# Grpmh. Two problems. A minor problem: it would have been much better
-# to have the `m4_eval' computed, and a major problem: you lost the
-# quotation in the result.
-#
-# Let's address the big problem first. One solution is to define any
-# modern macro to rewrite its calls with the proper quotation, thanks to
-# `$@'. Again, tracing the `define's makes it possible to know which
-# are these macros, so you input is:
-#
-# divert(-1)dnl
-# changequote([, ])
-# define([OLD], [NEW([$1, $2], m4_eval([$1 + $2]))changequote()])
-# define([NEW], [[NEW($@)]changequote()])
-# undefine([dnl])
-# undefine([m4_eval])
-# # Some more undefines...
-# changequote()
-# divert(0)dnl
-# dnl The Unbelievable Truth
-# changequote([, ])OLD(1, 2)
-# changequote([, ])NEW([0, 0],
-# 0)
-#
-# which results in
-#
-# dnl The Unbelievable Truth
-# NEW([1, 2],[m4_eval(1 + 2)])
-# NEW([0, 0],[0])
-#
-# Our problem is solved, i.e., the first call to `NEW' is properly
-# quoted, but introduced another problem: we changed the layout of the
-# second calls, which can be a drama in the case of huge macro calls
-# (think of `AC_TRY_RUN' for instance). This example didn't show it,
-# but we also introduced parens to macros which did not have some:
-#
-# AC_INIT
-# => AC_INIT()
-#
-# No big deal for the semantics (unless the macro depends upon $#, which
-# is bad), but the users would not be happy.
-#
-# Additionally, we introduced quotes that we not there before, which is
-# OK in most cases, but could change the semantics of the file.
-#
-# Cruel dilemma: we do want the auto-quoting definition of `NEW' when
-# evaluating `OLD', but we don't when we evaluate the second `NEW'.
-# Back to namespaces?
-#
-# No.
-#
-#
-# # Second step: replacement
-# # ------------------------
-#
-# No, as announced above, we will work in two steps: in a first step we
-# compute the updated values, and in a second step we replace them. Our
-# goal is something like this:
-#
-# divert(-1)dnl
-# changequote([, ])
-# define([OLD], [NEW([1, 2], [3])changequote()])
-# undefine([dnl])
-# undefine([m4_eval])
-# # Some more undefines...
-# changequote()
-# divert(0)dnl
-# dnl The Unbelievable Truth
-# changequote([, ])OLD(1, 2)
-# NEW([0, 0],
-# 0)
-#
-# i.e., the new value of `OLD' is precomputed using the auto-quoting
-# definition of `NEW' and the m4 builtins. We'll see how afterwards,
-# let's finish with the replacement.
-#
-# Of course the solution above is wrong: if there were other calls to
-# `OLD' with different values, we would smash them to the same value.
-# But it is quite easy to generalize the scheme above:
-#
-# divert(-1)dnl
-# changequote([, ])
-# define([OLD([1],[2])], [NEW([1, 2], [3])])
-# define([OLD], [defn([OLD($@)])changequote()])
-# undefine([dnl])
-# undefine([m4_eval])
-# # Some more undefines...
-# changequote()
-# divert(0)dnl
-# dnl The Unbelievable Truth
-# changequote([, ])OLD(1, 2)
-# NEW([0, 0],
-# 0)
-#
-# i.e., for each call to obsolete macros, we build an array `call =>
-# value', and use a macro to dispatch these values. This results in:
-#
-# dnl The Unbelievable Truth
-# NEW([1, 2], [3])
-# NEW([0, 0],
-# 0)
-#
-# In French, we say `Youpi !', which you might roughly translate as
-# `yipeee!'.
-#
-#
-# # First step: computation
-# # -----------------------
-#
-# Let's study the anatomy of the file, and name its sections:
-#
-# prologue
-# divert(-1)dnl
-# changequote([, ])
-# values
-# define([OLD([1],[2])], [NEW([1, 2], [3])])
-# dispatcher
-# define([OLD], [defn([OLD($@)])changequote()])
-# disabler
-# undefine([dnl])
-# undefine([m4_eval])
-# # Some more undefines...
-# changequote()
-# divert(0)dnl
-# input
-# dnl The Unbelievable Truth
-# changequote([, ])OLD(1, 2)
-# NEW([0, 0],
-# 0)
-#
-#
-# # Computing the `values' section
-# # ..............................
-#
-# First we need to get the list of all the AU macro uses. To this end,
-# first get the list of all the AU macros names by tracing `AU_DEFUN' in
-# the initialization of autoconf. This list is computed in the file
-# `au.txt' below.
-#
-# Then use this list to trace all the AU macro uses in the input. The
-# goal is obtain in the case of our example:
-#
-# [define([OLD([1],[2])],]@<<@OLD([1],[2])@>>@[)]
-#
-# This is the file `values.in' below.
-#
-# We want to evaluate this with only the builtins (in fact m4sugar), the
-# auto-quoting definitions of the new macros (`new.m4'), and the
-# definition of the old macros (`old.m4'). Computing these last two
-# files is easy: it's just a matter of using the right `--trace' option.
-#
-# So the content of `values.in' is:
-#
-# include($autoconf_dir/m4sugar.m4)
-# m4_include(new.m4)
-# m4_include(old.m4)
-# divert(0)dnl
-# [define([OLD([1],[2])],]@<<@OLD([1],[2])@>>@[)]
-#
-# We run m4 on it, which yields:
-#
-# define([OLD([1],[2])],@<<@NEW([1, 2], [3])@>>@)
-#
-# Transform `@<<@' and `@>>@' into quotes and we get
-#
-# define([OLD([1],[2])],[NEW([1, 2], [3])])
-#
-# This is `values.m4'.
-#
-#
-# # Computing the `dispatcher' section
-# # ..................................
-#
-# The `prologue', and the `disabler' are simple and need no commenting.
-#
-# To compute the `dispatcher' (`dispatch.m4'), again, it is a simple
-# matter of using the right `--trace'.
-#
-# Finally, the input is not exactly the input file, rather it is the
-# input file with the added `changequote'. To this end, we build
-# `quote.sed'.
-#
-#
-# # Putting it all together
-# # .......................
-#
-# We build the file `input.m4' which contains:
-#
-# divert(-1)dnl
-# changequote([, ])
-# include(values.m4)
-# include(dispatch.m4)
-# undefine([dnl])
-# undefine([eval])
-# # Some more undefines...
-# changequote()
-# divert(0)dnl
-# dnl The Unbelievable Truth
-# changequote([, ])OLD(1, 2)
-# NEW([0, 0],
-# 0)
-#
-# And we just run m4 on it. Et voila`, Monsieur ! Mais oui, mais oui.
-#
-# Well, there are a few additional technicalities. For instance, we
-# rely on `changequote', `ifelse' and `defn', but we don't want to
-# interpret the changequotes of the user, so we simply use another name:
-# `_au_changequote' etc.
-#
-#
-# # Failure of the fourth approach
-# # ------------------------------
-#
-# This approach is heavily based on traces, but then there is an obvious
-# problem: non expanded code will never be seen/ In particular, the body
-# of a `define' definition is not seen, so on the input
-#
-# define([idem], [OLD(0, [$1])])
-#
-# autoupdate would never see the `OLD', and wouldn't have updated it.
-# Worse yet, if `idem(0)' was used later, then autoupdate sees that
-# `OLD' is used, computes the result for `OLD(0, 0)' and sets up a
-# dispatcher for `OLD'. Since there was no computed value for `OLD(0,
-# [$1])', the dispatcher would have replaced with... nothinhg, leading
-# to
-#
-# define([idem], [])
-#
-# With some more thinking, you see that the two step approach is wrong,
-# the namespace approach was much saner.
-#
-# But you learned a lot, in particular you realized that using traces
-# can make it possible to simulate namespaces!
-#
-#
-#
-# # The fifth implementation: m4 namespaces by files
-# # ================================================
-#
-# The fourth implementation demonstrated something unsurprising: you
-# cannot precompute, i.e., the namespace approach was the right one.
-# Still, we no longer want them, they're too expensive. Let's have a
-# look at the way it worked.
-#
-# When updating
-#
-# dnl The Unbelievable Truth
-# OLD(1, 2)
-# NEW([0, 0], [0])
-#
-# you evaluate `input.m4':
-#
-# divert(-1)
-# changequote([, ])
-# define([OLD],
-# [m4_enable()NEW([$1, $2], m4_eval([$1 + $2]))m4_disable()])
-# ...
-# m4_disable()
-# dnl The Unbelievable Truth
-# OLD(1, 2)
-# NEW([0, 0], [0])
-#
-# where `m4_disable' undefines the m4 and m4sugar, and disables the quotes
-# and comments:
-#
-# define([m4_disable],
-# [undefine([__file__])
-# ...
-# changecom(#)
-# changequote()])
-#
-# `m4_enable' does the converse: reestablish quotes and comments
-# --easy--, reestablish m4sugar --easy: just load `m4sugar.m4' again-- and
-# reenable the builtins. This later task requires that you first save
-# the builtins. And BTW, the definition above of `m4_disable' cannot
-# work: you undefined `changequote' before using it! So you need to use
-# your privates copies of the builtins. Let's introduce three files for
-# this:
-#
-# `m4save.m4'
-# moves the m4 builtins into the `_au_' pseudo namespace
-# `unm4.m4'
-# undefines the builtins
-# `m4.m4'
-# restores them
-#
-# So `input.m4' is:
-#
-# divert(-1)
-# changequote([, ])
-#
-# include([m4save.m4])
-#
-# # Import AU.
-# define([OLD],
-# [m4_enable()NEW([$1, $2], m4_eval([$1 + $2]))m4_disable()])
-#
-# define([_au_enable],
-# [_au_changecom([#])
-# _au_include([m4.m4])
-# _au_include(m4sugar.m4)])
-#
-# define([_au_disable],
-# [# Disable m4sugar.
-# # Disable the m4 builtins.
-# _au_include([unm4.m4])
-# # 1. Disable special characters.
-# _au_changequote()
-# _au_changecom()])
-#
-# m4_disable()
-# dnl The Unbelievable Truth
-# OLD(1, 2)
-# NEW([0, 0], [0])
-#
-# Based on what we learned in the fourth implementation we know that we
-# have to enable the quotes *before* any AU macro, and we know we need
-# to build autoquoting versions of the AC macros. But the autoquoting
-# AC definitions must be disabled in the rest of the file, and enabled
-# inside AU macros.
-#
-# Using `autoconf --trace' it is easy to build the files
-#
-# `ac.m4'
-# define the autoquoting AC fake macros
-# `disable.m4'
-# undefine the m4sugar and AC autoquoting macros.
-# `au.m4'
-# definitions of the AU macros (such as `OLD' above).
-#
-# Now, `input.m4' is:
-#
-# divert(-1)
-# changequote([, ])
-#
-# include([m4save.m4])
-# # Import AU.
-# include([au.m4])
-#
-# define([_au_enable],
-# [_au_changecom([#])
-# _au_include([m4.m4])
-# _au_include(m4sugar.m4)
-# _au_include(ac.m4)])
-#
-# define([_au_disable],
-# [_au_include([disable.m4])
-# _au_include([unm4.m4])
-# # 1. Disable special characters.
-# _au_changequote()
-# _au_changecom()])
-#
-# m4_disable()
-# dnl The Unbelievable Truth
-# _au_changequote([, ])OLD(1, 2)
-# NEW([0, 0], [0])
-#
-# Finally, version V is ready.
-#
-# Well... almost.
-#
-# There is a slight problem that remains: if an AU macro OUTTER includes
-# an AU macro INNER, then _au_enable will be run when entering OUTTER
-# and when entering INNER (not good, but not too bad yet). But when
-# getting out of INNER, _au_disable will disable everything while we
-# were still in OUTTER. Badaboom.
-#
-# Therefore _au_enable and _au_disable have to be written to work by
-# pairs: each _au_enable pushdef's _au_enabled, and each _au_disable
-# popdef's _au_enabled. And of course _au_enable and _au_disable are
-# effective when _au_enabled is *not* defined.
-#
-# Finally, version V' is ready. And there is much rejoicing. (And I
-# have free time again. I think. Yeah, right.)

-% @multitable macros
-% Amy Hendrickson, 8/18/94, 3/6/96
-%
-% @multitable ... @end multitable will make as many columns as desired.
-% Contents of each column will wrap at width given in preamble. Width
-% can be specified either with sample text given in a template line,
-% or in percent of \hsize, the current width of text on page.
-
-% Table can continue over pages but will only break between lines.
-
-% To make preamble:
-%
-% Either define widths of columns in terms of percent of \hsize:
-% @multitable @columnfractions .25 .3 .45
-% @item ...
-%
-% Numbers following @columnfractions are the percent of the total
-% current hsize to be used for each column. You may use as many
-% columns as desired.
-
-
-% Or use a template:
-% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-% @item ...
-% using the widest term desired in each column.
-%
-% For those who want to use more than one line's worth of words in
-% the preamble, break the line within one argument and it
-% will parse correctly, i.e.,
-%
-% @multitable {Column 1 template} {Column 2 template} {Column 3
-% template}
-% Not:
-% @multitable {Column 1 template} {Column 2 template}
-% {Column 3 template}
-
-% Each new table line starts with @item, each subsequent new column
-% starts with @tab. Empty columns may be produced by supplying @tab's
-% with nothing between them for as many times as empty columns are needed,
-% ie, @tab@tab@tab will produce two empty columns.
-
-% @item, @tab, @multitable or @end multitable do not need to be on their
-% own lines, but it will not hurt if they are.
-
-% Sample multitable:
-
-% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-% @item first col stuff @tab second col stuff @tab third col
-% @item
-% first col stuff
-% @tab
-% second col stuff
-% @tab
-% third col
-% @item first col stuff @tab second col stuff
-% @tab Many paragraphs of text may be used in any column.
-%
-% They will wrap at the width determined by the template.
-% @item@tab@tab This will be in third column.
-% @end multitable
-
-% Default dimensions may be reset by user.
-% @multitableparskip is vertical space between paragraphs in table.
-% @multitableparindent is paragraph indent in table.
-% @multitablecolmargin is horizontal space to be left between columns.
-% @multitablelinespace is space to leave between table items, baseline
-% to baseline.
-% 0pt means it depends on current normal line spacing.

-
- Autoconf is a tool for producing shell scripts that automatically
-configure software source code packages to adapt to many kinds of
-UNIX-like systems. The configuration scripts produced by Autoconf are
-independent of Autoconf when they are run, so their users do not need
-to have Autoconf.
-
- The configuration scripts produced by Autoconf require no manual user
-intervention when run; they do not normally even need an argument
-specifying the system type. Instead, they individually test for the
-presence of each feature that the software package they are for might
-need. (Before each check, they print a one-line message stating what
-they are checking for, so the user doesn't get too bored while waiting
-for the script to finish.) As a result, they deal well with systems
-that are hybrids or customized from the more common UNIX variants.
-There is no need to maintain files that list the features supported by
-each release of each variant of UNIX.
-
- For each software package that Autoconf is used with, it creates a
-configuration script from a template file that lists the system features
-that the package needs or can use. After the shell code to recognize
-and respond to a system feature has been written, Autoconf allows it to
-be shared by many software packages that can use (or need) that feature.
-If it later turns out that the shell code needs adjustment for some
-reason, it needs to be changed in only one place; all of the
-configuration scripts can be regenerated automatically to take advantage
-of the updated code.
-
- The Metaconfig package is similar in purpose to Autoconf, but the
-scripts it produces require manual user intervention, which is quite
-inconvenient when configuring large source trees. Unlike Metaconfig
-scripts, Autoconf scripts can support cross-compiling, if some care is
-taken in writing them.
-
- Autoconf does not solve all problems related to making portable
-software packages--for a more complete solution, it should be used in
-concert with other GNU build tools like Automake and Libtool. These
-other tools take on jobs like the creation of a portable, recursive
-`Makefile' with all of the standard targets, linking of shared
-libraries, and so on. *Note The GNU build system::, for more
-information.
-
- Autoconf imposes some restrictions on the names of macros used with
-`#if' in C programs (*note Preprocessor Symbol Index::).
-
- Autoconf requires GNU M4 in order to generate the scripts. It uses
-features that some UNIX versions of M4, including GNU M4 1.3, do not
-have. You must use version 1.4 or later of GNU M4.
-
- *Note Autoconf 1::, for information about upgrading from version 1.
-*Note History::, for the story of Autoconf's development. *Note
-Questions::, for answers to some common questions about Autoconf.
-
- See the Autoconf web page(1) for up-to-date information, details on
-the mailing lists, pointers to a list of known bugs, etc.
-
- Mail suggestions to the Autoconf mailing list <autoconf@gnu.org>.
-
- Bug reports should be preferably submitted to the Autoconf Gnats
-database(2), or sent to the Autoconf Bugs mailing list
-<bug-autoconf@gnu.org>. If possible, first check that your bug is not
-already solved in current development versions, and that it has not
-been reported yet. Be sure to include all the needed information and a
-short `configure.ac' that demonstrates the problem.
-
- Autoconf's development tree is accessible via CVS; see the Autoconf
-web page for details. There is also a CVSweb interface to the Autoconf
-development tree(3). Patches relative to the current CVS version can
-be sent for review to the Autoconf Patches mailing list
-<autoconf-patches@gnu.org>.
-
- Because of its mission, Autoconf includes only a set of often-used
-macros that have already demonstrated their usefulness. Nevertheless,
-if you wish to share your macros, or find existing ones, see the
-Autoconf Macro Archive(4), which is kindly run by Peter Simons
-<simons@computer.org>.

-The GNU build system
-********************
-
- Autoconf solves an important problem--reliable discovery of
-system-specific build and runtime information--but this is only one
-piece of the puzzle for the development of portable software. To this
-end, the GNU project has developed a suite of integrated utilities to
-finish the job Autoconf started: the GNU build system, whose most
-important components are Autoconf, Automake, and Libtool. In this
-chapter, we introduce you to those tools, point you to sources of more
-information, and try to convince you to use the entire GNU build system
-for your software.

-
-Automake
-========
-
- The ubiquity of `make' means that a `Makefile' is almost the only
-viable way to distribute automatic build rules for software, but one
-quickly runs into `make''s numerous limitations. Its lack of support
-for automatic dependency tracking, recursive builds in subdirectories,
-reliable timestamps (e.g. for network filesystems), and so on, mean
-that developers must painfully (and often incorrectly) reinvent the
-wheel for each project. Portability is non-trivial, thanks to the
-quirks of `make' on many systems. On top of all this is the manual
-labor required to implement the many standard targets that users have
-come to expect (`make install', `make distclean', `make uninstall',
-etc.). Since you are, of course, using Autoconf, you also have to
-insert repetitive code in your `Makefile.in' to recognize `@CC@',
-`@CFLAGS@', and other substitutions provided by `configure'. Into this
-mess steps "Automake".
-
- Automake allows you to specify your build needs in a `Makefile.am'
-file with a vastly simpler and more powerful syntax than that of a plain
-`Makefile', and then generates a portable `Makefile.in' for use with
-Autoconf. For example, the `Makefile.am' to build and install a simple
-"Hello world" program might look like:
-
- bin_PROGRAMS = hello
- hello_SOURCES = hello.c
-
-The resulting `Makefile.in' (~400 lines) automatically supports all the
-standard targets, the substitutions provided by Autoconf, automatic
-dependency tracking, `VPATH' building, and so on. `make' will build
-the `hello' program, and `make install' will install it in
-`/usr/local/bin' (or whatever prefix was given to `configure', if not
-`/usr/local').
-
- Automake may require that additional tools be present on the
-_developer's_ machine. For example, the `Makefile.in' that the
-developer works with may not be portable (e.g. it might use special
-features of your compiler to automatically generate dependency
-information). Running `make dist', however, produces a
-`hello-1.0.tar.gz' package (or whatever the program/version is) with a
-`Makefile.in' that will work on any system.
-
- The benefits of Automake increase for larger packages (especially
-ones with subdirectories), but even for small programs the added
-convenience and portability can be substantial. And that's not all...
-
-
-File: autoconf.info, Node: Libtool, Next: Pointers, Prev: Automake, Up: The GNU build system
-
-Libtool
-=======
-
- Very often, one wants to build not only programs, but libraries, so
-that other programs can benefit from the fruits of your labor.
-Ideally, one would like to produce _shared_ (dynamically-linked)
-libraries, which can be used by multiple programs without duplication
-on disk or in memory and can be updated independently of the linked
-programs. Producing shared libraries portably, however, is the stuff of
-nightmares--each system has its own incompatible tools, compiler flags,
-and magic incantations. Fortunately, GNU provides a solution:
-"Libtool".
-
- Libtool handles all the requirements of building shared libraries for
-you, and at this time seems to be the _only_ way to do so with any
-portability. It also handles many other headaches, such as: the
-interaction of `Makefile' rules with the variable suffixes of shared
-libraries, linking reliably to shared libraries before they are
-installed by the superuser, and supplying a consistent versioning system
-(so that different versions of a library can be installed or upgraded
-without breaking binary compatibility). Although Libtool, like
-Autoconf, can be used on its own, it is most simply utilized in
-conjunction with Automake--there, Libtool is used automatically
-whenever shared libraries are needed, and you need not know its syntax.

-
-Pointers
-========
-
- Developers who are used to the simplicity of `make' for small
-projects on a single system might be daunted at the prospect of learning
-to use Automake and Autoconf. As your software is distributed to more
-and more users, however, you will otherwise quickly find yourself
-putting lots of effort into reinventing the services that the GNU build
-tools provide, and making the same mistakes that they once made and
-overcame. (Besides, since you're already learning Autoconf, Automake
-will be a piece of cake.)

-
-Making `configure' Scripts
-**************************
-
- The configuration scripts that Autoconf produces are by convention
-called `configure'. When run, `configure' creates several files,
-replacing configuration parameters in them with appropriate values.
-The files that `configure' creates are:
-
- - one or more `Makefile' files, one in each subdirectory of the
- package (*note Makefile Substitutions::);
-
- - optionally, a C header file, the name of which is configurable,
- containing `#define' directives (*note Configuration Headers::);
-
- - a shell script called `config.status' that, when run, will recreate
- the files listed above (*note config.status Invocation::);
-
- - an optional shell script normally called `config.cache' (created
- when using `configure --config-cache') that saves the results of
- running many of the tests (*note Cache Files::);
-
- - a file called `config.log' containing any messages produced by
- compilers, to help debugging if `configure' makes a mistake.
-
- To create a `configure' script with Autoconf, you need to write an
-Autoconf input file `configure.ac' (or `configure.in') and run
-`autoconf' on it. If you write your own feature tests to supplement
-those that come with Autoconf, you might also write files called
-`aclocal.m4' and `acsite.m4'. If you use a C header file to contain
-`#define' directives, you might also run `autoheader', and you will
-distribute the generated file `config.h.in' with the package.
-
- Here is a diagram showing how the files that can be used in
-configuration are produced. Programs that are executed are suffixed by
-`*'. Optional files are enclosed in square brackets (`[]').
-`autoconf' and `autoheader' also read the installed Autoconf macro
-files (by reading `autoconf.m4').

-
-Writing `configure.ac'
-======================
-
- To produce a `configure' script for a software package, create a
-file called `configure.ac' that contains invocations of the Autoconf
-macros that test the system features your package needs or can use.
-Autoconf macros already exist to check for many features; see *Note
-Existing Tests::, for their descriptions. For most other features, you
-can use Autoconf template macros to produce custom checks; see *Note
-Writing Tests::, for information about them. For especially tricky or
-specialized features, `configure.ac' might need to contain some
-hand-crafted shell commands; see *Note Portable Shell::. The
-`autoscan' program can give you a good start in writing `configure.ac'
-(*note autoscan Invocation::, for more information).
-
- Previous versions of Autoconf promoted the name `configure.in',
-which is somewhat ambiguous (the tool needed to produce this file is not
-described by its extension), and introduces a slight confusion with
-`config.h.in' and so on (for which `.in' means "to be processed by
-`configure'"). Using `configure.ac' is now preferred.

-
-A Shell Script Compiler
------------------------
-
- Just as for any other computer language, in order to properly program
-`configure.ac' in Autoconf you must understand _what_ problem the
-language tries to address and _how_ it does so.
-
- The problem Autoconf addresses is that the world is a mess. After
-all, you are using Autoconf in order to have your package compile
-easily on all sorts of different systems, some of them being extremely
-hostile. Autoconf itself bears the price for these differences:
-`configure' must run on all those systems, and thus `configure' must
-limit itself to their lowest common denominator of features.
-
- Naturally, you might then think of shell scripts; who needs
-`autoconf'? A set of properly written shell functions is enough to
-make it easy to write `configure' scripts by hand. Sigh!
-Unfortunately, shell functions do not belong to the least common
-denominator; therefore, where you would like to define a function and
-use it ten times, you would instead need to copy its body ten times.
-
- So, what is really needed is some kind of compiler, `autoconf', that
-takes an Autoconf program, `configure.ac', and transforms it into a
-portable shell script, `configure'.
-
- How does `autoconf' perform this task?
-
- There are two obvious possibilities: creating a brand new language or
-extending an existing one. The former option is very attractive: all
-sorts of optimizations could easily be implemented in the compiler and
-many rigorous checks could be performed on the Autoconf program (e.g.
-rejecting any non-portable construct). Alternatively, you can extend
-an existing language, such as the `sh' (Bourne shell) language.
-
- Autoconf does the latter: it is a layer on top of `sh'. It was
-therefore most convenient to implement `autoconf' as a macro expander:
-a program that repeatedly performs "macro expansions" on text input,
-replacing macro calls with macro bodies and producing a pure `sh'
-script in the end. Instead of implementing a dedicated Autoconf macro
-expander, it is natural to use an existing general-purpose macro
-language, such as M4, and implement the extensions as a set of M4
-macros.

-
-The Autoconf Language
----------------------
-
- The Autoconf language is very different from many other computer
-languages because it treats actual code the same as plain text. Whereas
-in C, for instance, data and instructions have very different syntactic
-status, in Autoconf their status is rigorously the same. Therefore, we
-need a means to distinguish literal strings from text to be expanded:
-quotation.
-
- When calling macros that take arguments, there must not be any blank
-space between the macro name and the open parenthesis. Arguments should
-be enclosed within the M4 quote characters `[' and `]', and be
-separated by commas. Any leading spaces in arguments are ignored,
-unless they are quoted. You may safely leave out the quotes when the
-argument is simple text, but _always_ quote complex arguments such as
-other macro calls. This rule applies recursively for every macro call,
-including macros called from other macros.
-
- For instance:
-
- AC_CHECK_HEADER([stdio.h],
- [AC_DEFINE([HAVE_STDIO_H])],
- [AC_MSG_ERROR([Sorry, can't do anything for you])])
-
-is quoted properly. You may safely simplify its quotation to:
-
- AC_CHECK_HEADER(stdio.h,
- [AC_DEFINE(HAVE_STDIO_H)],
- [AC_MSG_ERROR([Sorry, can't do anything for you])])
-
-Notice that the argument of `AC_MSG_ERROR' is still quoted; otherwise,
-its comma would have been interpreted as an argument separator.
-
- The following example is wrong and dangerous, as it is underquoted:
-
- AC_CHECK_HEADER(stdio.h,
- AC_DEFINE(HAVE_STDIO_H),
- AC_MSG_ERROR([Sorry, can't do anything for you]))
-
- In other cases, you may have to use text that also resembles a macro
-call. You must quote that text even when it is not passed as a macro
-argument:
-
- echo "Hard rock was here! --[AC_DC]"
-
-which will result in
-
- echo "Hard rock was here! --AC_DC"
-
-When you use the same text in a macro argument, you must therefore have
-an extra quotation level (since one is stripped away by the macro
-substitution). In general, then, it is a good idea to _use double
-quoting for all literal string arguments_:
-
- AC_MSG_WARN([[AC_DC stinks --Iron Maiden]])
-
- You are now able to understand one of the constructs of Autoconf that
-has been continually misunderstood... The rule of thumb is that
-_whenever you expect macro expansion, expect quote expansion_; i.e.,
-expect one level of quotes to be lost. For instance:
-
- AC_COMPILE_IFELSE([char b[10];],, [AC_MSG_ERROR([you lose])])
-
-is incorrect: here, the first argument of `AC_COMPILE_IFELSE' is `char
-b[10];' and will be expanded once, which results in `char b10;'.
-(There was an idiom common in Autoconf's past to address this issue via
-the M4 `changequote' primitive, but do not use it!) Let's take a
-closer look: the author meant the first argument to be understood as a
-literal, and therefore it must be quoted twice:
-
- AC_COMPILE_IFELSE([[char b[10];]],, [AC_MSG_ERROR([you lose])])
-
-Voila`, you actually produce `char b[10];' this time!
-
- The careful reader will notice that, according to these guidelines,
-the "properly" quoted `AC_CHECK_HEADER' example above is actually
-lacking three pairs of quotes! Nevertheless, for the sake of
-readability, double quotation of literals is used only where needed in
-this manual.
-
- Some macros take optional arguments, which this documentation
-represents as [ARG] (not to be confused with the quote characters).
-You may just leave them empty, or use `[]' to make the emptiness of the
-argument explicit, or you may simply omit the trailing commas. The
-three lines below are equivalent:
-
- AC_CHECK_HEADERS(stdio.h, [], [], [])
- AC_CHECK_HEADERS(stdio.h,,,)
- AC_CHECK_HEADERS(stdio.h)
-
- It is best to put each macro call on its own line in `configure.ac'.
-Most of the macros don't add extra newlines; they rely on the newline
-after the macro call to terminate the commands. This approach makes
-the generated `configure' script a little easier to read by not
-inserting lots of blank lines. It is generally safe to set shell
-variables on the same line as a macro call, because the shell allows
-assignments without intervening newlines.
-
- You can include comments in `configure.ac' files by starting them
-with the `#'. For example, it is helpful to begin `configure.ac' files
-with a line like this:
-
- # Process this file with autoconf to produce a configure script.
-
-
-File: autoconf.info, Node: configure.ac Layout, Prev: Autoconf Language, Up: Writing configure.ac
-
-Standard `configure.ac' Layout
-------------------------------
-
- The order in which `configure.ac' calls the Autoconf macros is not
-important, with a few exceptions. Every `configure.ac' must contain a
-call to `AC_INIT' before the checks, and a call to `AC_OUTPUT' at the
-end (*note Output::). Additionally, some macros rely on other macros
-having been called first, because they check previously set values of
-some variables to decide what to do. These macros are noted in the
-individual descriptions (*note Existing Tests::), and they also warn
-you when `configure' is created if they are called out of order.
-
- To encourage consistency, here is a suggested order for calling the
-Autoconf macros. Generally speaking, the things near the end of this
-list are those that could depend on things earlier in it. For example,
-library functions could be affected by types and libraries.
-
- Autoconf requirements
- `AC_INIT(PACKAGE, VERSION, BUG-REPORT-ADDRESS)'
- information on the package
- checks for programs
- checks for libraries
- checks for header files
- checks for types
- checks for structures
- checks for compiler characteristics
- checks for library functions
- checks for system services
- `AC_CONFIG_FILES([FILE...])'
- `AC_OUTPUT'
-

-
-Using `autoscan' to Create `configure.ac'
-=========================================
-
- The `autoscan' program can help you create and/or maintain a
-`configure.ac' file for a software package. `autoscan' examines source
-files in the directory tree rooted at a directory given as a command
-line argument, or the current directory if none is given. It searches
-the source files for common portability problems and creates a file
-`configure.scan' which is a preliminary `configure.ac' for that
-package, and checks a possibly existing `configure.ac' for completeness.
-
- When using `autoscan' to create a `configure.ac', you should
-manually examine `configure.scan' before renaming it to `configure.ac';
-it will probably need some adjustments. Occasionally, `autoscan'
-outputs a macro in the wrong order relative to another macro, so that
-`autoconf' produces a warning; you need to move such macros manually.
-Also, if you want the package to use a configuration header file, you
-must add a call to `AC_CONFIG_HEADERS' (*note Configuration Headers::).
-You might also have to change or add some `#if' directives to your
-program in order to make it work with Autoconf (*note ifnames
-Invocation::, for information about a program that can help with that
-job).
-
- When using `autoscan' to maintain a `configure.ac', simply consider
-adding its suggestions. The file `autoscan.log' will contain detailed
-information on why a macro is requested.
-
- `autoscan' uses several data files (installed along with Autoconf)
-to determine which macros to output when it finds particular symbols in
-a package's source files. These data files all have the same format:
-each line consists of a symbol, whitespace, and the Autoconf macro to
-output if that symbol is encountered. Lines starting with `#' are
-comments.
-
- `autoscan' is only installed if you already have Perl installed.
-`autoscan' accepts the following options:
-
-`--help'
-`-h'
- Print a summary of the command line options and exit.
-
-`--version'
-`-V'
- Print the version number of Autoconf and exit.
-
-`--verbose'
-`-v'
- Print the names of the files it examines and the potentially
- interesting symbols it finds in them. This output can be
- voluminous.
-
-`--autoconf-dir=DIR'
-`-A DIR'
- Override the location where the installed Autoconf data files are
- looked for. You can also set the `AC_MACRODIR' environment
- variable to a directory; this option overrides the environment
- variable.
-
- This option is rarely needed and dangerous; it is only used when
- one plays with different versions of Autoconf simultaneously.
-
-
-File: autoconf.info, Node: ifnames Invocation, Next: autoconf Invocation, Prev: autoscan Invocation, Up: Making configure Scripts
-
-Using `ifnames' to List Conditionals
-====================================
-
- `ifnames' can help you write `configure.ac' for a software package.
-It prints the identifiers that the package already uses in C
-preprocessor conditionals. If a package has already been set up to have
-some portability, `ifnames' can thus help you figure out what its
-`configure' needs to check for. It may help fill in some gaps in a
-`configure.ac' generated by `autoscan' (*note autoscan Invocation::).
-
- `ifnames' scans all of the C source files named on the command line
-(or the standard input, if none are given) and writes to the standard
-output a sorted list of all the identifiers that appear in those files
-in `#if', `#elif', `#ifdef', or `#ifndef' directives. It prints each
-identifier on a line, followed by a space-separated list of the files
-in which that identifier occurs.
-
-`ifnames' accepts the following options:
-
-`--help'
-`-h'
- Print a summary of the command line options and exit.
-
-`--version'
-`-V'
- Print the version number of Autoconf and exit.
-
-
-File: autoconf.info, Node: autoconf Invocation, Next: autoreconf Invocation, Prev: ifnames Invocation, Up: Making configure Scripts
-
-Using `autoconf' to Create `configure'
-======================================
-
- To create `configure' from `configure.ac', run the `autoconf'
-program with no arguments. `autoconf' processes `configure.ac' with
-the `m4' macro processor, using the Autoconf macros. If you give
-`autoconf' an argument, it reads that file instead of `configure.ac'
-and writes the configuration script to the standard output instead of
-to `configure'. If you give `autoconf' the argument `-', it reads from
-the standard input instead of `configure.ac' and writes the
-configuration script to the standard output.
-
- The Autoconf macros are defined in several files. Some of the files
-are distributed with Autoconf; `autoconf' reads them first. Then it
-looks for the optional file `acsite.m4' in the directory that contains
-the distributed Autoconf macro files, and for the optional file
-`aclocal.m4' in the current directory. Those files can contain your
-site's or the package's own Autoconf macro definitions (*note Writing
-Autoconf Macros::, for more information). If a macro is defined in
-more than one of the files that `autoconf' reads, the last definition
-it reads overrides the earlier ones.
-
- `autoconf' accepts the following options:
-
-`--help'
-`-h'
- Print a summary of the command line options and exit.
-
-`--version'
-`-V'
- Print the version number of Autoconf and exit.
-
-`--verbose'
-`-v'
- Report processing steps.
-
-`--debug'
-`-d'
- Don't remove the temporary files.
-
-`--autoconf-dir=DIR'
-`-A DIR'
- Override the location where the installed Autoconf data files are
- looked for. You can also set the `AC_MACRODIR' environment
- variable to a directory; this option overrides the environment
- variable.
-
- This option is rarely needed and dangerous; it is only used when
- one plays with different versions of Autoconf simultaneously.
-
-`--localdir=DIR'
-`-l DIR'
- Look for the package file `aclocal.m4' in directory DIR instead of
- in the current directory.
-
-`--output=FILE'
-`-o FILE'
- Save output (script or trace) to FILE. The file `-' stands for
- the standard output.
-
-`--warnings=CATEGORY'
-`-W CATEGORY'
- Report the warnings related to CATEGORY (which can actually be a
- comma separated list). *Note Reporting Messages::, macro
- `AC_DIAGNOSE', for a comprehensive list of categories. Special
- values include:
-
- `all'
- report all the warnings
-
- `none'
- report none
-
- `error'
- treats warnings as errors
-
- `no-CATEGORY'
- disable warnings falling into CATEGORY
-
- Warnings about `syntax' are enabled by default, and the environment
- variable `WARNINGS', a comma separated list of categories, is
- honored. `autoconf -W CATEGORY' will actually behave as if you had
- run:
-
- autoconf --warnings=syntax,$WARNINGS,CATEGORY
-
- If you want to disable `autoconf''s defaults and `WARNINGS', but
- (for example) enable the warnings about obsolete constructs, you
- would use `-W none,obsolete'.
-
- `autoconf' displays a back trace for errors, but not for warnings;
- if you want them, just pass `-W error'. For instance, on this
- `configure.ac':
-
- AC_DEFUN([INNER],
- [AC_TRY_RUN([true])])
-
- AC_DEFUN([OUTER],
- [INNER])
-
- AC_INIT
- OUTER
-
- you get:
-
- $ autoconf -Wcross
- configure.ac:8: warning: AC_TRY_RUN called without default \
- to allow cross compiling
- $ autoconf -Wcross,error
- configure.ac:8: error: AC_TRY_RUN called without default \
- to allow cross compiling
- acgeneral.m4:3044: AC_TRY_RUN is expanded from...
- configure.ac:2: INNER is expanded from...
- configure.ac:5: OUTER is expanded from...
- configure.ac:8: the top level
-
-`--trace=MACRO[:FORMAT]'
-`-t MACRO[:FORMAT]'
- Do not create the `configure' script, but list the calls to MACRO
- according to the FORMAT. Multiple `--trace' arguments can be used
- to list several macros. Multiple `--trace' arguments for a single
- macro are not cumulative; instead, you should just make FORMAT as
- long as needed.
-
- The FORMAT is a regular string, with newlines if desired, and
- several special escape codes. It defaults to `$f:$l:$n:$%'; see
- below for details on the FORMAT.
-
-`--initialization'
-`-i'
- By default, `--trace' does not trace the initialization of the
- Autoconf macros (typically the `AC_DEFUN' definitions). This
- results in a noticeable speedup, but can be disabled by this
- option.
-
- It is often necessary to check the content of a `configure.ac' file,
-but parsing it yourself is extremely fragile and error-prone. It is
-suggested that you rely upon `--trace' to scan `configure.ac'.
-
- The FORMAT of `--trace' can use the following special escapes:
-
-`$$'
- The character `$'.
-
-`$f'
- The filename from which MACRO is called.
-
-`$l'
- The line number from which MACRO is called.
-
-`$d'
- The depth of the MACRO call. This is an M4 technical detail that
- you probably don't want to know about.
-
-`$n'
- The name of the MACRO.
-
-`$NUM'
- The NUMth argument of the call to MACRO.
-
-`$@'
-`$SEP@'
-`${SEPARATOR}@'
- All the arguments passed to MACRO, separated by the character SEP
- or the string SEPARATOR (`,' by default). Each argument is
- quoted, i.e. enclosed in a pair of square brackets.
-
-`$*'
-`$SEP*'
-`${SEPARATOR}*'
- As above, but the arguments are not quoted.
-
-`$%'
-`$SEP%'
-`${SEPARATOR}%'
- As above, but the arguments are not quoted, all new line
- characters in the arguments are smashed, and the default separator
- is `:'.
-
- The escape `$%' produces single-line trace outputs (unless you put
- newlines in the `separator'), while `$@' and `$*' do not.
-
- For instance, to find the list of variables that are substituted,
-use:
-
- $ autoconf -t AC_SUBST
- configure.ac:2:AC_SUBST:ECHO_C
- configure.ac:2:AC_SUBST:ECHO_N
- configure.ac:2:AC_SUBST:ECHO_T
- More traces deleted
-
-The example below highlights the difference between `$@', `$*', and
-*$%*.
-
- $ cat configure.ac
- AC_DEFINE(This, is, [an
- [example]])
- $ autoconf -t 'AC_DEFINE:@: $@
- *: $*
- $: $%'
- @: [This],[is],[an
- [example]]
- *: This,is,an
- [example]
- $: This:is:an [example]
-
-The FORMAT gives you a lot of freedom:
-
- $ autoconf -t 'AC_SUBST:$$ac_subst{"$1"} = "$f:$l";'
- $ac_subst{"ECHO_C"} = "configure.ac:2";
- $ac_subst{"ECHO_N"} = "configure.ac:2";
- $ac_subst{"ECHO_T"} = "configure.ac:2";
- More traces deleted
-
-A long SEPARATOR can be used to improve the readability of complex
-structures, and to ease its parsing (for instance when no single
-character is suitable as a separator)):
-
- $ autoconf -t 'AM_MISSING_PROG:${|:::::|}*'
- ACLOCAL|:::::|aclocal|:::::|$missing_dir
- AUTOCONF|:::::|autoconf|:::::|$missing_dir
- AUTOMAKE|:::::|automake|:::::|$missing_dir
- More traces deleted

-
-Using `autoreconf' to Update `configure' Scripts
-================================================
-
- If you have a lot of Autoconf-generated `configure' scripts, the
-`autoreconf' program can save you some work. It runs `autoconf' (and
-`autoheader', where appropriate) repeatedly to remake the Autoconf
-`configure' scripts and configuration header templates in the directory
-tree rooted at the current directory. By default, it only remakes
-those files that are older than their `configure.ac' or (if present)
-`aclocal.m4'. Since `autoheader' does not change the timestamp of its
-output file if the file wouldn't be changing, this is not necessarily
-the minimum amount of work. If you install a new version of Autoconf,
-you can make `autoreconf' remake _all_ of the files by giving it the
-`--force' option.
-
- If you give `autoreconf' the `--autoconf-dir=DIR' or
-`--localdir=DIR' options, it passes them down to `autoconf' and
-`autoheader' (with relative paths adjusted properly).
-
- `autoreconf' does not support having, in the same directory tree,
-both directories that are parts of a larger package (sharing
-`aclocal.m4' and `acconfig.h') and directories that are independent
-packages (each with their own `aclocal.m4' and `acconfig.h'). It
-assumes that they are all part of the same package if you use
-`--localdir', or that each directory is a separate package if you don't
-use it. This restriction may be removed in the future.
-
- *Note Automatic Remaking::, for `Makefile' rules to automatically
-remake `configure' scripts when their source files change. That method
-handles the timestamps of configuration header templates properly, but
-does not pass `--autoconf-dir=DIR' or `--localdir=DIR'.
-
-`autoreconf' accepts the following options:
-
-`--help'
-`-h'
- Print a summary of the command line options and exit.
-
-`--version'
-`-V'
- Print the version number of Autoconf and exit.
-
-`--verbose'
- Print the name of each directory where `autoreconf' runs
- `autoconf' (and `autoheader', if appropriate).
-
-`--debug'
-`-d'
- Don't remove the temporary files.
-
-`--force'
-`-f'
- Remake even `configure' scripts and configuration headers that are
- newer than their input files (`configure.ac' and, if present,
- `aclocal.m4').
-
-`--install'
-`-i'
- Copy missing auxiliary files. This option is similar to the option
- `--add-missing' in `automake'.
-
-`--symlink'
-`-s'
- Instead of copying missing auxiliary files, install symbolic links.
-
-`--localdir=DIR'
-`-l DIR'
- Have `autoconf' and `autoheader' look for the package files
- `aclocal.m4' and (`autoheader' only) `acconfig.h' (but not
- `FILE.top' and `FILE.bot') in directory DIR instead of in the
- directory containing each `configure.ac'.
-
-`--autoconf-dir=DIR'
-`-A DIR'
- Override the location where the installed Autoconf data files are
- looked for. You can also set the `AC_MACRODIR' environment
- variable to a directory; this option overrides the environment
- variable.
-
- This option is rarely needed and dangerous; it is only used when
- one plays with different versions of Autoconf simultaneously.
-
-`--m4dir=DIR'
-`-M DIR'
- Specify location of additional macro files (`m4' by default).
-
- Additionally, the following options are recognized and passed to
-`automake':
-
-`--cygnus'
- Assume program is part of Cygnus-style tree.
-
-`--foreign'
- Set strictness to foreign.
-
-`--gnits'
- Set strictness to gnits.
-
-`--gnu'
- Set strictness to gnu.
-
-`--include-deps'
- Include generated dependencies in `Makefile.in'.

-
-Notices in `configure'
-======================
-
- The following macros manage version numbers for `configure' scripts.
-Using them is optional.
-
- - Macro: AC_PREREQ (VERSION)
- Ensure that a recent enough version of Autoconf is being used. If
- the version of Autoconf being used to create `configure' is earlier
- than VERSION, print an error message to the standard error output
- and do not create `configure'. For example:
-
- AC_PREREQ(2.52)
-
- This macro is the only macro that may be used before `AC_INIT', but
- for consistency, you are invited not to do so.
-
- - Macro: AC_COPYRIGHT (COPYRIGHT-NOTICE)
- State that, in addition to the Free Software Foundation's
- copyright on the Autoconf macros, parts of your `configure' are
- covered by the COPYRIGHT-NOTICE.
-
- The COPYRIGHT-NOTICE will show up in both the head of `configure'
- and in `configure --version'.
-
- - Macro: AC_REVISION (REVISION-INFO)
- Copy revision stamp REVISION-INFO into the `configure' script,
- with any dollar signs or double-quotes removed. This macro lets
- you put a revision stamp from `configure.ac' into `configure'
- without RCS or `cvs' changing it when you check in `configure'.
- That way, you can determine easily which revision of
- `configure.ac' a particular `configure' corresponds to.
-
- For example, this line in `configure.ac':
-
- AC_REVISION($Revision: 1.1.1.1 $)
-
- produces this in `configure':
-
- #! /bin/sh
- # From configure.ac Revision: 1.30
-
-
-File: autoconf.info, Node: Input, Next: Output, Prev: Notices, Up: Setup
-
-Finding `configure' Input
-=========================
-
- Every `configure' script must call `AC_INIT' before doing anything
-else. The only other required macro is `AC_OUTPUT' (*note Output::).
-
- - Macro: AC_INIT (PACKAGE, VERSION, [BUG-REPORT-ADDRESS])
- Process any command-line arguments and perform various
- initializations and verifications. Set the name of the PACKAGE
- and its VERSION. The optional argument BUG-REPORT-ADDRESS should
- be the email to which users should send bug reports.
-
- - Macro: AC_CONFIG_SRCDIR (UNIQUE-FILE-IN-SOURCE-DIR)
- UNIQUE-FILE-IN-SOURCE-DIR is some file that is in the package's
- source directory; `configure' checks for this file's existence to
- make sure that the directory that it is told contains the source
- code in fact does. Occasionally people accidentally specify the
- wrong directory with `--srcdir'; this is a safety check. *Note
- configure Invocation::, for more information.
-
- Packages that do manual configuration or use the `install' program
-might need to tell `configure' where to find some other shell scripts
-by calling `AC_CONFIG_AUX_DIR', though the default places it looks are
-correct for most cases.
-
- - Macro: AC_CONFIG_AUX_DIR (DIR)
- Use the auxiliary build tools (e.g., `install-sh', `config.sub',
- `config.guess', Cygnus `configure', Automake and Libtool scripts
- etc.) that are in directory DIR. These are auxiliary files used
- in configuration. DIR can be either absolute or relative to
- `SRCDIR'. The default is `SRCDIR' or `SRCDIR/..' or
- `SRCDIR/../..', whichever is the first that contains `install-sh'.
- The other files are not checked for, so that using
- `AC_PROG_INSTALL' does not automatically require distributing the
- other auxiliary files. It checks for `install.sh' also, but that
- name is obsolete because some `make' have a rule that creates
- `install' from it if there is no `Makefile'.
-
-
-File: autoconf.info, Node: Output, Next: Configuration Actions, Prev: Input, Up: Setup
-
-Outputting Files
-================
-
- Every Autoconf-generated `configure' script must finish by calling
-`AC_OUTPUT'. It is the macro that generates `config.status', which
-will create the `Makefile's and any other files resulting from
-configuration. The only other required macro is `AC_INIT' (*note
-Input::).
-
- - Macro: AC_OUTPUT
- Generate `config.status' and launch it. Call this macro once, at
- the end of `configure.ac'.
-
- `config.status' will take all the configuration actions: all the
- output files (see *Note Configuration Files::, macro
- `AC_CONFIG_FILES'), header files (see *Note Configuration
- Headers::, macro `AC_CONFIG_HEADERS'), commands (see *Note
- Configuration Commands::, macro `AC_CONFIG_COMMANDS'), links (see
- *Note Configuration Links::, macro `AC_CONFIG_LINKS'),
- subdirectories to configure (see *Note Subdirectories::, macro
- `AC_CONFIG_SUBDIRS') are honored.
-
- Historically, the usage of `AC_OUTPUT' was somewhat different.
-*Note Obsolete Macros::, for a description of the arguments that
-`AC_OUTPUT' used to support.
-
- If you run `make' on subdirectories, you should run it using the
-`make' variable `MAKE'. Most versions of `make' set `MAKE' to the name
-of the `make' program plus any options it was given. (But many do not
-include in it the values of any variables set on the command line, so
-those are not passed on automatically.) Some old versions of `make' do
-not set this variable. The following macro allows you to use it even
-with those versions.
-
- - Macro: AC_PROG_MAKE_SET
- If `make' predefines the variable `MAKE', define output variable
- `SET_MAKE' to be empty. Otherwise, define `SET_MAKE' to contain
- `MAKE=make'. Calls `AC_SUBST' for `SET_MAKE'.
-
- To use this macro, place a line like this in each `Makefile.in' that
-runs `MAKE' on other directories:
-
- @SET_MAKE@

-Taking Configuration Actions
-============================
-
- `configure' is designed so that it appears to do everything itself,
-but there is actually a hidden slave: `config.status'. `configure' is
-in charge of examining your system, but it is `config.status' that
-actually takes the proper actions based on the results of `configure'.
-The most typical task of `config.status' is to _instantiate_ files.
-
- This section describes the common behavior of the four standard
-instantiating macros: `AC_CONFIG_FILES', `AC_CONFIG_HEADERS',
-`AC_CONFIG_COMMANDS' and `AC_CONFIG_LINKS'. They all have this
-prototype:
-
- AC_CONFIG_FOOS(TAG..., [COMMANDS], [INIT-CMDS])
-
-where the arguments are:
-
-TAG...
- A whitespace-separated list of tags, which are typically the names
- of the files to instantiate.
-
-COMMANDS
- Shell commands output literally into `config.status', and
- associated with a tag that the user can use to tell `config.status'
- which the commands to run. The commands are run each time a TAG
- request is given to `config.status'; typically, each time the file
- `TAG' is created.
-
-INIT-CMDS
- Shell commands output _unquoted_ near the beginning of
- `config.status', and executed each time `config.status' runs
- (regardless of the tag). Because they are unquoted, for example,
- `$var' will be output as the value of `var'. INIT-CMDS is
- typically used by `configure' to give `config.status' some
- variables it needs to run the COMMANDS.
-
- All these macros can be called multiple times, with different TAGs,
-of course!
-
- You are encouraged to use literals as TAGS. In particular, you
-should avoid
-
- ... && my_foos="$my_foos fooo"
- ... && my_foos="$my_foos foooo"
- AC_CONFIG_FOOS($my_foos)
-
-and use this instead:
-
- ... && AC_CONFIG_FOOS(fooo)
- ... && AC_CONFIG_FOOS(foooo)
-
- The macro `AC_CONFIG_FILES' and `AC_CONFIG_HEADERS' use specials
-TAGs: they may have the form `OUTPUT' or `OUTPUT:INPUTS'. The file
-OUTPUT is instantiated from its templates, INPUTS if specified,
-defaulting to `OUTPUT.in'.
-
- For instance `AC_CONFIG_FILES(Makefile:boiler/top.mk:boiler/bot.mk)'
-asks for the creation of `Makefile' that will be the expansion of the
-output variables in the concatenation of `boiler/top.mk' and
-`boiler/bot.mk'.
-
- The special value `-' might be used to denote the standard output
-when used in OUTPUT, or the standard input when used in the INPUTS.
-You most probably don't need to use this in `configure.ac', but it is
-convenient when using the command line interface of `./config.status',
-see *Note config.status Invocation::, for more details.
-
- The INPUTS may be absolute or relative filenames. In the latter
-case they are first looked for in the build tree, and then in the source
-tree.

-
-Creating Configuration Files
-============================
-
- Be sure to read the previous section, *Note Configuration Actions::.
-
- - Macro: AC_CONFIG_FILES (FILE..., [CMDS], [INIT-CMDS])
- Make `AC_OUTPUT' create each `FILE' by copying an input file (by
- default `FILE.in'), substituting the output variable values. This
- macro is one of the instantiating macros, see *Note Configuration
- Actions::. *Note Makefile Substitutions::, for more information
- on using output variables. *Note Setting Output Variables::, for
- more information on creating them. This macro creates the
- directory that the file is in if it doesn't exist. Usually,
- `Makefile's are created this way, but other files, such as
- `.gdbinit', can be specified as well.
-
- Typical calls to `AC_CONFIG_FILES' look like this:
-
- AC_CONFIG_FILES(Makefile src/Makefile man/Makefile X/Imakefile)
- AC_CONFIG_FILES(autoconf, chmod +x autoconf)
-
- You can override an input file name by appending to FILE a
- colon-separated list of input files. Examples:
-
- AC_CONFIG_FILES(Makefile:boiler/top.mk:boiler/bot.mk
- lib/Makefile:boiler/lib.mk)
-
- Doing this allows you to keep your file names acceptable to
- MS-DOS, or to prepend and/or append boilerplate to the file.

-
-Substitutions in Makefiles
-==========================
-
- Each subdirectory in a distribution that contains something to be
-compiled or installed should come with a file `Makefile.in', from which
-`configure' will create a `Makefile' in that directory. To create a
-`Makefile', `configure' performs a simple variable substitution,
-replacing occurrences of `@VARIABLE@' in `Makefile.in' with the value
-that `configure' has determined for that variable. Variables that are
-substituted into output files in this way are called "output
-variables". They are ordinary shell variables that are set in
-`configure'. To make `configure' substitute a particular variable into
-the output files, the macro `AC_SUBST' must be called with that
-variable name as an argument. Any occurrences of `@VARIABLE@' for
-other variables are left unchanged. *Note Setting Output Variables::,
-for more information on creating output variables with `AC_SUBST'.
-
- A software package that uses a `configure' script should be
-distributed with a file `Makefile.in', but no `Makefile'; that way, the
-user has to properly configure the package for the local system before
-compiling it.
-
- *Note Makefile Conventions: (standards)Makefile Conventions, for
-more information on what to put in `Makefile's.

-Preset Output Variables
------------------------
-
- Some output variables are preset by the Autoconf macros. Some of the
-Autoconf macros set additional output variables, which are mentioned in
-the descriptions for those macros. *Note Output Variable Index::, for a
-complete list of output variables. *Note Installation Directory
-Variables::, for the list of the preset ones related to installation
-directories. Below are listed the other preset ones. They all are
-precious variables (*note Setting Output Variables::, `AC_ARG_VAR').
-
- - Variable: CFLAGS
- Debugging and optimization options for the C compiler. If it is
- not set in the environment when `configure' runs, the default
- value is set when you call `AC_PROG_CC' (or empty if you don't).
- `configure' uses this variable when compiling programs to test for
- C features.
-
- - Variable: configure_input
- A comment saying that the file was generated automatically by
- `configure' and giving the name of the input file. `AC_OUTPUT'
- adds a comment line containing this variable to the top of every
- `Makefile' it creates. For other files, you should reference this
- variable in a comment at the top of each input file. For example,
- an input shell script should begin like this:
-
- #! /bin/sh
- # @configure_input@
-
- The presence of that line also reminds people editing the file
- that it needs to be processed by `configure' in order to be used.
-
- - Variable: CPPFLAGS
- Header file search directory (`-IDIR') and any other miscellaneous
- options for the C and C++ preprocessors and compilers. If it is
- not set in the environment when `configure' runs, the default
- value is empty. `configure' uses this variable when compiling or
- preprocessing programs to test for C and C++ features.
-
- - Variable: CXXFLAGS
- Debugging and optimization options for the C++ compiler. If it is
- not set in the environment when `configure' runs, the default
- value is set when you call `AC_PROG_CXX' (or empty if you don't).
- `configure' uses this variable when compiling programs to test for
- C++ features.
-
- - Variable: DEFS
- `-D' options to pass to the C compiler. If `AC_CONFIG_HEADERS' is
- called, `configure' replaces `@DEFS@' with `-DHAVE_CONFIG_H'
- instead (*note Configuration Headers::). This variable is not
- defined while `configure' is performing its tests, only when
- creating the output files. *Note Setting Output Variables::, for
- how to check the results of previous tests.
-
- - Variable: ECHO_C
- - Variable: ECHO_N
- - Variable: ECHO_T
- How does one suppress the trailing newline from `echo' for
- question-answer message pairs? These variables provide a way:
-
- echo $ECHO_N "And the winner is... $ECHO_C"
- sleep 100000000000
- echo "${ECHO_T}dead."
-
- Some old and uncommon `echo' implementations offer no means to
- achieve this, in which case `ECHO_T' is set to tab. You might not
- want to use it.
-
- - Variable: FFLAGS
- Debugging and optimization options for the Fortran 77 compiler.
- If it is not set in the environment when `configure' runs, the
- default value is set when you call `AC_PROG_F77' (or empty if you
- don't). `configure' uses this variable when compiling programs to
- test for Fortran 77 features.
-
- - Variable: LDFLAGS
- Stripping (`-s'), path (`-L'), and any other miscellaneous options
- for the linker. Don't use this variable to pass library names
- (`-l') to the linker, use `LIBS' instead. If it is not set in the
- environment when `configure' runs, the default value is empty.
- `configure' uses this variable when linking programs to test for
- C, C++ and Fortran 77 features.
-
- - Variable: LIBS
- `-l' options to pass to the linker. The default value is empty,
- but some Autoconf macros may prepend extra libraries to this
- variable if those libraries are found and provide necessary
- functions, see *Note Libraries::. `configure' uses this variable
- when linking programs to test for C, C++ and Fortran 77 features.
-
- - Variable: srcdir
- The directory that contains the source code for that `Makefile'.
-
- - Variable: top_srcdir
- The top-level source code directory for the package. In the
- top-level directory, this is the same as `srcdir'.
-
-
-File: autoconf.info, Node: Installation Directory Variables, Next: Build Directories, Prev: Preset Output Variables, Up: Makefile Substitutions
-
-Installation Directory Variables
---------------------------------
-
- The following variables specify the directories where the package
-will be installed, see *Note Variables for Installation Directories:
-(standards)Directory Variables, for more information. See the end of
-this section for details on when and how to use these variables.
-
- - Variable: bindir
- The directory for installing executables that users run.
-
- - Variable: datadir
- The directory for installing read-only architecture-independent
- data.
-
- - Variable: exec_prefix
- The installation prefix for architecture-dependent files. By
- default it's the same as PREFIX. You should avoid installing
- anything directly to EXEC_PREFIX. However, the default value for
- directories containing architecture-dependent files should be
- relative to EXEC_PREFIX.
-
- - Variable: includedir
- The directory for installing C header files.
-
- - Variable: infodir
- The directory for installing documentation in Info format.
-
- - Variable: libdir
- The directory for installing object code libraries.
-
- - Variable: libexecdir
- The directory for installing executables that other programs run.
-
- - Variable: localstatedir
- The directory for installing modifiable single-machine data.
-
- - Variable: mandir
- The top-level directory for installing documentation in man format.
-
- - Variable: oldincludedir
- The directory for installing C header files for non-gcc compilers.
-
- - Variable: prefix
- The common installation prefix for all files. If EXEC_PREFIX is
- defined to a different value, PREFIX is used only for
- architecture-independent files.
-
- - Variable: sbindir
- The directory for installing executables that system
- administrators run.
-
- - Variable: sharedstatedir
- The directory for installing modifiable architecture-independent
- data.
-
- - Variable: sysconfdir
- The directory for installing read-only single-machine data.
-
- Most of these variables have values that rely on `prefix' or
-`exec_prefix'. It is on purpose that the directory output variables
-keep them unexpanded: typically `@datadir@' will be replaced by
-`${prefix}/share', not `/usr/local/share'.
-
- This behavior is mandated by the GNU coding standards, so that when
-the user runs:
-
-`make'
- she can still specify a different prefix from the one specified to
- `configure', in which case, if needed, the package shall hard code
- dependencies to her late desires.
-
-`make install'
- she can specify a different installation location, in which case
- the package _must_ still depend on the location which was compiled
- in (i.e., never recompile when `make install' is run). This is an
- extremely important feature, as many people may decide to install
- all the files of a package grouped together, and then install
- links from the final locations to there.
-
- In order to support these features, it is essential that `datadir'
-remains being defined as `${prefix}/share' to depend upon the current
-value of `prefix'.
-
- A corollary is that you should not use these variables but in
-Makefiles. For instance, instead of trying to evaluate `datadir' in
-`configure' and hardcoding it in Makefiles using e.g.
-`AC_DEFINE_UNQUOTED(DATADIR, "$datadir")', you should add
-`-DDATADIR="$(datadir)"' to your `CPPFLAGS'.
-
- Similarly you should not rely on `AC_OUTPUT_FILES' to replace
-`datadir' and friends in your shell scripts and other files, rather let
-`make' manage their replacement. For instance Autoconf ships templates
-of its shell scripts ending with `.sh', and uses this Makefile snippet:
-
- .sh:
- rm -f $@ $@.tmp
- sed 's,@datadir\@,$(pkgdatadir),g' $< >$@.tmp
- chmod +x $@.tmp
- mv $@.tmp $@
-
- Three things are noteworthy:
-
-`@datadir\@'
- The backslash prevents `configure' from replacing `@datadir@' in
- the sed expression itself.
-
-`$(pkgdatadir)'
- Don't use `@pkgdatadir@'! Use the matching makefile variable
- instead.
-
-`,'
- Don't use `/' in the sed expression(s) since most probably the
- variables you use, such as `$(pkgdatadir)', will contain some.

-
-Build Directories
------------------
-
- You can support compiling a software package for several
-architectures simultaneously from the same copy of the source code.
-The object files for each architecture are kept in their own directory.
-
- To support doing this, `make' uses the `VPATH' variable to find the
-files that are in the source directory. GNU `make' and most other
-recent `make' programs can do this. Older `make' programs do not
-support `VPATH'; when using them, the source code must be in the same
-directory as the object files.
-
- To support `VPATH', each `Makefile.in' should contain two lines that
-look like:
-
- srcdir = @srcdir@
- VPATH = @srcdir@
-
- Do not set `VPATH' to the value of another variable, for example
-`VPATH = $(srcdir)', because some versions of `make' do not do variable
-substitutions on the value of `VPATH'.
-
- `configure' substitutes in the correct value for `srcdir' when it
-produces `Makefile'.
-
- Do not use the `make' variable `$<', which expands to the file name
-of the file in the source directory (found with `VPATH'), except in
-implicit rules. (An implicit rule is one such as `.c.o', which tells
-how to create a `.o' file from a `.c' file.) Some versions of `make'
-do not set `$<' in explicit rules; they expand it to an empty value.
-
- Instead, `Makefile' command lines should always refer to source
-files by prefixing them with `$(srcdir)/'. For example:
-
- time.info: time.texinfo
- $(MAKEINFO) $(srcdir)/time.texinfo
-
-
-File: autoconf.info, Node: Automatic Remaking, Prev: Build Directories, Up: Makefile Substitutions
-
-Automatic Remaking
-------------------
-
- You can put rules like the following in the top-level `Makefile.in'
-for a package to automatically update the configuration information when
-you change the configuration files. This example includes all of the
-optional files, such as `aclocal.m4' and those related to configuration
-header files. Omit from the `Makefile.in' rules for any of these files
-that your package does not use.
-
- The `$(srcdir)/' prefix is included because of limitations in the
-`VPATH' mechanism.
-
- The `stamp-' files are necessary because the timestamps of
-`config.h.in' and `config.h' will not be changed if remaking them does
-not change their contents. This feature avoids unnecessary
-recompilation. You should include the file `stamp-h.in' your package's
-distribution, so `make' will consider `config.h.in' up to date. Don't
-use `touch' (*note Limitations of Usual Tools::), rather use `echo'
-(using `date' would cause needless differences, hence CVS conflicts
-etc.).
-
- $(srcdir)/configure: configure.ac aclocal.m4
- cd $(srcdir) && autoconf
-
- # autoheader might not change config.h.in, so touch a stamp file.
- $(srcdir)/config.h.in: stamp-h.in
- $(srcdir)/stamp-h.in: configure.ac aclocal.m4
- cd $(srcdir) && autoheader
- echo timestamp > $(srcdir)/stamp-h.in
-
- config.h: stamp-h
- stamp-h: config.h.in config.status
- ./config.status
-
- Makefile: Makefile.in config.status
- ./config.status
-
- config.status: configure
- ./config.status --recheck
-
-(Be careful if you copy these lines directly into your Makefile, as you
-will need to convert the indented lines to start with the tab
-character.)
-
- In addition, you should use `AC_CONFIG_FILES(stamp-h, echo timestamp
-> stamp-h)' so `config.status' will ensure that `config.h' is
-considered up to date. *Note Output::, for more information about
-`AC_OUTPUT'.
-
- *Note config.status Invocation::, for more examples of handling
-configuration-related dependencies.

-
-Configuration Header Files
-==========================
-
- When a package tests more than a few C preprocessor symbols, the
-command lines to pass `-D' options to the compiler can get quite long.
-This causes two problems. One is that the `make' output is hard to
-visually scan for errors. More seriously, the command lines can exceed
-the length limits of some operating systems. As an alternative to
-passing `-D' options to the compiler, `configure' scripts can create a
-C header file containing `#define' directives. The `AC_CONFIG_HEADERS'
-macro selects this kind of output. It should be called right after
-`AC_INIT'.
-
- The package should `#include' the configuration header file before
-any other header files, to prevent inconsistencies in declarations (for
-example, if it redefines `const'). Use `#include <config.h>' instead
-of `#include "config.h"', and pass the C compiler a `-I.' option (or
-`-I..'; whichever directory contains `config.h'). That way, even if
-the source directory is configured itself (perhaps to make a
-distribution), other build directories can also be configured without
-finding the `config.h' from the source directory.
-
- - Macro: AC_CONFIG_HEADERS (HEADER ..., [CMDS], [INIT-CMDS])
- This macro is one of the instantiating macros, see *Note
- Configuration Actions::. Make `AC_OUTPUT' create the file(s) in
- the whitespace-separated list HEADER containing C preprocessor
- `#define' statements, and replace `@DEFS@' in generated files with
- `-DHAVE_CONFIG_H' instead of the value of `DEFS'. The usual name
- for HEADER is `config.h'.
-
- If HEADER already exists and its contents are identical to what
- `AC_OUTPUT' would put in it, it is left alone. Doing this allows
- some changes in configuration without needlessly causing object
- files that depend on the header file to be recompiled.
-
- Usually the input file is named `HEADER.in'; however, you can
- override the input file name by appending to HEADER, a
- colon-separated list of input files. Examples:
-
- AC_CONFIG_HEADERS(config.h:config.hin)
- AC_CONFIG_HEADERS(defines.h:defs.pre:defines.h.in:defs.post)
-
- Doing this allows you to keep your file names acceptable to
- MS-DOS, or to prepend and/or append boilerplate to the file.

-
-Configuration Header Templates
-------------------------------
-
- Your distribution should contain a template file that looks as you
-want the final header file to look, including comments, with `#undef'
-statements which are used as hooks. For example, suppose your
-`configure.ac' makes these calls:
-
- AC_CONFIG_HEADERS(conf.h)
- AC_CHECK_HEADERS(unistd.h)
-
-Then you could have code like the following in `conf.h.in'. On systems
-that have `unistd.h', `configure' will `#define' `HAVE_UNISTD_H' to 1.
-On other systems, the whole line will be commented out (in case the
-system predefines that symbol).
-
- /* Define as 1 if you have unistd.h. */
- #undef HAVE_UNISTD_H
-
- You can then decode the configuration header using the preprocessor
-directives:
-
- #include <conf.h>
-
- #if HAVE_UNISTD_H
- # include <unistd.h>
- #else
- /* We are in trouble. */
- #endif
-
- The use of old form templates, with `#define' instead of `#undef' is
-strongly discouraged.
-
- Since it is a tedious task to keep a template header up to date, you
-may use `autoheader' to generate it, see *Note autoheader Invocation::.
-
-
-File: autoconf.info, Node: autoheader Invocation, Next: Autoheader Macros, Prev: Header Templates, Up: Configuration Headers
-
-Using `autoheader' to Create `config.h.in'
-------------------------------------------
-
- The `autoheader' program can create a template file of C `#define'
-statements for `configure' to use. If `configure.ac' invokes
-`AC_CONFIG_HEADERS(FILE)', `autoheader' creates `FILE.in'; if multiple
-file arguments are given, the first one is used. Otherwise,
-`autoheader' creates `config.h.in'.
-
- In order to do its job, `autoheader' needs you to document all of
-the symbols that you might use; i.e., there must be at least one
-`AC_DEFINE' or one `AC_DEFINE_UNQUOTED' using its third argument for
-each symbol (*note Defining Symbols::). An additional constraint is
-that the first argument of `AC_DEFINE' must be a literal. Note that
-all symbols defined by Autoconf's built-in tests are already documented
-properly; you only need to document those that you define yourself.
-
- You might wonder why `autoheader' is needed: after all, why would
-`configure' need to "patch" a `config.h.in' to produce a `config.h'
-instead of just creating `config.h' from scratch? Well, when
-everything rocks, the answer is just that we are wasting our time
-maintaining `autoheader': generating `config.h' directly is all that is
-needed. When things go wrong, however, you'll be thankful for the
-existence of `autoheader'.
-
- The fact that the symbols are documented is important in order to
-_check_ that `config.h' makes sense. The fact that there is a well
-defined list of symbols that should be `#define''d (or not) is also
-important for people who are porting packages to environments where
-`configure' cannot be run: they just have to _fill in the blanks_.
-
- But let's come back to the point: `autoheader''s invocation...
-
- If you give `autoheader' an argument, it uses that file instead of
-`configure.ac' and writes the header file to the standard output
-instead of to `config.h.in'. If you give `autoheader' an argument of
-`-', it reads the standard input instead of `configure.ac' and writes
-the header file to the standard output.
-
- `autoheader' accepts the following options:
-
-`--help'
-`-h'
- Print a summary of the command line options and exit.
-
-`--version'
-`-V'
- Print the version number of Autoconf and exit.
-
-`--debug'
-`-d'
- Don't remove the temporary files.
-
-`--verbose'
-`-v'
- Report processing steps.
-
-`--autoconf-dir=DIR'
-`-A DIR'
- Override the location where the installed Autoconf data files are
- looked for. You can also set the `AC_MACRODIR' environment
- variable to a directory; this option overrides the environment
- variable.
-
- This option is rarely needed and dangerous; it is only used when
- one plays with different versions of Autoconf simultaneously.
-
-`--localdir=DIR'
-`-l DIR'
- Look for the package files `aclocal.m4' and `acconfig.h' (but not
- `FILE.top' and `FILE.bot') in directory DIR instead of in the
- current directory.
-
-`--warnings=CATEGORY'
-`-W CATEGORY'
- Report the warnings related to CATEGORY (which can actually be a
- comma separated list). Current categories include:
-
- `obsolete'
- report the uses of obsolete constructs
-
- `all'
- report all the warnings
-
- `none'
- report none
-
- `error'
- treats warnings as errors
-
- `no-CATEGORY'
- disable warnings falling into CATEGORY

-Autoheader Macros
------------------
-
- `autoheader' scans `configure.ac' and figures out which C
-preprocessor symbols it might define. It knows how to generate
-templates for symbols defined by `AC_CHECK_HEADERS', `AC_CHECK_FUNCS'
-etc., but if you `AC_DEFINE' any additional symbol, you must define a
-template for it. If there are missing templates, `autoheader' fails
-with an error message.
-
- The simplest way to create a template for a SYMBOL is to supply the
-DESCRIPTION argument to an `AC_DEFINE(SYMBOL)'; see *Note Defining
-Symbols::. You may also use one of the following macros.
-
- - Macro: AH_VERBATIM (KEY, TEMPLATE)
- Tell `autoheader' to include the TEMPLATE as-is in the header
- template file. This TEMPLATE is associated with the KEY, which is
- used to sort all the different templates and guarantee their
- uniqueness. It should be the symbol that can be `AC_DEFINE''d.
-
- For example:

-Running Arbitrary Configuration Commands
-========================================
-
- You execute arbitrary commands either before, during and after
-`config.status' is run. The three following macros accumulate the
-commands to run when they are called multiple times.
-`AC_CONFIG_COMMANDS' replaces the obsolete macro `AC_OUTPUT_COMMANDS',
-see *Note Obsolete Macros::, for details.
-
- - Macro: AC_CONFIG_COMMANDS (TAG..., [CMDS], [INIT-CMDS])
- Specify additional shell commands to run at the end of
- `config.status', and shell commands to initialize any variables
- from `configure'. Associate the commands to the TAG. Since
- typically the CMDS create a file, TAG should naturally be the name
- of that file. This macro is one of the instantiating macros, see
- *Note Configuration Actions::.
-
- Here is an unrealistic example:
- fubar=42
- AC_CONFIG_COMMANDS(fubar,
- [echo this is extra $fubar, and so on.],
- [fubar=$fubar])
-
- Here is a better one:
- AC_CONFIG_COMMANDS(time-stamp, [date >time-stamp])
-
- - Macro: AC_CONFIG_COMMANDS_PRE (CMDS)
- Execute the CMDS right before creating `config.status'. A typical
- use is computing values derived from variables built during the
- execution of `configure':
-
- AC_CONFIG_COMMANDS_PRE(
- [LTLIBOBJS=`echo $LIBOBJS | sed 's/\.o/\.lo/g'`
- AC_SUBST(LTLIBOBJS)])
-
- - Macro: AC_CONFIG_COMMANDS_POST (CMDS)
- Execute the CMDS right after creating `config.status'.
-
-
-File: autoconf.info, Node: Configuration Links, Next: Subdirectories, Prev: Configuration Commands, Up: Setup
-
-Creating Configuration Links
-============================
-
- You may find it convenient to create links whose destinations depend
-upon results of tests. One can use `AC_CONFIG_COMMANDS' but the
-creation of relative symbolic links can be delicate when the package is
-built in another directory than its sources.
-
- - Macro: AC_CONFIG_LINKS (DEST:SOURCE..., [CMDS], [INIT-CMDS])
- Make `AC_OUTPUT' link each of the existing files SOURCE to the
- corresponding link name DEST. Makes a symbolic link if possible,
- otherwise a hard link. The DEST and SOURCE names should be
- relative to the top level source or build directory. This macro
- is one of the instantiating macros, see *Note Configuration
- Actions::.
-
- For example, this call:
-
- AC_CONFIG_LINKS(host.h:config/$machine.h
- object.h:config/$obj_format.h)
-
- creates in the current directory `host.h' as a link to
- `SRCDIR/config/$machine.h', and `object.h' as a link to
- `SRCDIR/config/$obj_format.h'.
-
- The tempting value `.' for DEST is invalid: it makes it impossible
- for `config.status' to guess the links to establish.
-
- One can then run:
- ./config.status host.h object.h
-
- to create the links.
-
-
-File: autoconf.info, Node: Subdirectories, Next: Default Prefix, Prev: Configuration Links, Up: Setup
-
-Configuring Other Packages in Subdirectories
-============================================
-
- In most situations, calling `AC_OUTPUT' is sufficient to produce
-`Makefile's in subdirectories. However, `configure' scripts that
-control more than one independent package can use `AC_CONFIG_SUBDIRS'
-to run `configure' scripts for other packages in subdirectories.
-
- - Macro: AC_CONFIG_SUBDIRS (DIR ...)
- Make `AC_OUTPUT' run `configure' in each subdirectory DIR in the
- given whitespace-separated list. Each DIR should be a literal,
- i.e., please do not use:
-
- if test "$package_foo_enabled" = yes; then
- $my_subdirs="$my_subdirs foo"
- fi
- AC_CONFIG_SUBDIRS($my_subdirs)
-
- because this prevents `./configure --help=recursive' from
- displaying the options of the package `foo'. Rather, you should
- write:
-
- if test "$package_foo_enabled" = yes then;
- AC_CONFIG_SUBDIRS(foo)
- fi
-
- If a given DIR is not found, no error is reported, so a
- `configure' script can configure whichever parts of a large source
- tree are present. If a given DIR contains `configure.gnu', it is
- run instead of `configure'. This is for packages that might use a
- non-autoconf script `Configure', which can't be called through a
- wrapper `configure' since it would be the same file on
- case-insensitive filesystems. Likewise, if a DIR contains
- `configure.ac' but no `configure', the Cygnus `configure' script
- found by `AC_CONFIG_AUX_DIR' is used.
-
- The subdirectory `configure' scripts are given the same command
- line options that were given to this `configure' script, with minor
- changes if needed (e.g., to adjust a relative path for the cache
- file or source directory). This macro also sets the output
- variable `subdirs' to the list of directories `DIR ...'.
- `Makefile' rules can use this variable to determine which
- subdirectories to recurse into. This macro may be called multiple
- times.
-
-
-File: autoconf.info, Node: Default Prefix, Prev: Subdirectories, Up: Setup
-
-Default Prefix
-==============
-
- By default, `configure' sets the prefix for files it installs to
-`/usr/local'. The user of `configure' can select a different prefix
-using the `--prefix' and `--exec-prefix' options. There are two ways
-to change the default: when creating `configure', and when running it.
-
- Some software packages might want to install in a directory besides
-`/usr/local' by default. To accomplish that, use the
-`AC_PREFIX_DEFAULT' macro.
-
- - Macro: AC_PREFIX_DEFAULT (PREFIX)
- Set the default installation prefix to PREFIX instead of
- `/usr/local'.
-
- It may be convenient for users to have `configure' guess the
-installation prefix from the location of a related program that they
-have already installed. If you wish to do that, you can call
-`AC_PREFIX_PROGRAM'.
-
- - Macro: AC_PREFIX_PROGRAM (PROGRAM)
- If the user did not specify an installation prefix (using the
- `--prefix' option), guess a value for it by looking for PROGRAM in
- `PATH', the way the shell does. If PROGRAM is found, set the
- prefix to the parent of the directory containing PROGRAM;
- otherwise leave the prefix specified in `Makefile.in' unchanged.
- For example, if PROGRAM is `gcc' and the `PATH' contains
- `/usr/local/gnu/bin/gcc', set the prefix to `/usr/local/gnu'.

-Existing Tests
-**************
-
- These macros test for particular system features that packages might
-need or want to use. If you need to test for a kind of feature that
-none of these macros check for, you can probably do it by calling
-primitive test macros with appropriate arguments (*note Writing
-Tests::).
-
- These tests print messages telling the user which feature they're
-checking for, and what they find. They cache their results for future
-`configure' runs (*note Caching Results::).
-
- Some of these macros set output variables. *Note Makefile
-Substitutions::, for how to get their values. The phrase "define NAME"
-is used below as a shorthand to mean "define C preprocessor symbol NAME
-to the value 1". *Note Defining Symbols::, for how to get those symbol
-definitions into your program.

-Common Behavior
-===============
-
- Much effort has been expended to make Autoconf easy to learn. The
-most obvious way to reach this goal is simply to enforce standard
-interfaces and behaviors, avoiding exceptions as much as possible.
-Because of history and inertia, unfortunately, there are still too many
-exceptions in Autoconf; nevertheless, this section describes some of
-the common rules.
-
-* Menu:
-
-* Standard Symbols:: Symbols defined by the macros
-* Default Includes:: Includes used by the generic macros
-
-
-File: autoconf.info, Node: Standard Symbols, Next: Default Includes, Prev: Common Behavior, Up: Common Behavior
-
-Standard Symbols
-----------------
-
- All the generic macros that `AC_DEFINE' a symbol as a result of
-their test transform their ARGUMENTs to a standard alphabet. First,
-ARGUMENT is converted to upper case and any asterisks (`*') are each
-converted to `P'. Any remaining characters that are not alphanumeric
-are converted to underscores.
-
- For instance,
-
- AC_CHECK_TYPES(struct $Expensive*)
-
-will define the symbol `HAVE_STRUCT__EXPENSIVEP' if the check succeeds.
-
-
-File: autoconf.info, Node: Default Includes, Prev: Standard Symbols, Up: Common Behavior
-
-Default Includes
-----------------
-
- Several tests depend upon a set of header files. Since these headers
-are not universally available, tests actually have to provide a set of
-protected includes, such as:
-
- #if TIME_WITH_SYS_TIME
- # include <sys/time.h>
- # include <time.h>
- #else
- # if HAVE_SYS_TIME_H
- # include <sys/time.h>
- # else
- # include <time.h>
- # endif
- #endif
-
-Unless you know exactly what you are doing, you should avoid using
-unconditional includes, and check the existence of the headers you
-include beforehand (*note Header Files::).
-
- Most generic macros provide the following default set of includes:
-
- #include <stdio.h>
- #if HAVE_SYS_TYPES_H
- # include <sys/types.h>
- #endif
- #if HAVE_SYS_STAT_H
- # include <sys/stat.h>
- #endif
- #if STDC_HEADERS
- # include <stdlib.h>
- # include <stddef.h>
- #else
- # if HAVE_STDLIB_H
- # include <stdlib.h>
- # endif
- #endif
- #if HAVE_STRING_H
- # if !STDC_HEADERS && HAVE_MEMORY_H
- # include <memory.h>
- # endif
- # include <string.h>
- #endif
- #if HAVE_STRINGS_H
- # include <strings.h>
- #endif
- #if HAVE_INTTYPES_H
- # include <inttypes.h>
- #else
- # if HAVE_STDINT_H
- # include <stdint.h>
- # endif
- #endif
- #if HAVE_UNISTD_H
- # include <unistd.h>
- #endif
-
- If the default includes are used, then Autoconf will automatically
-check for the presence of these headers and their compatibility, i.e.,
-you don't need to run `AC_HEADERS_STDC', nor check for `stdlib.h' etc.
-
- These headers are checked for in the same order as they are included.
-For instance, on some systems `string.h' and `strings.h' both exist,
-but conflict. Then `HAVE_STRING_H' will be defined, but
-`HAVE_STRINGS_H' won't.

-Alternative Programs
-====================
-
- These macros check for the presence or behavior of particular
-programs. They are used to choose between several alternative programs
-and to decide what to do once one has been chosen. If there is no macro
-specifically defined to check for a program you need, and you don't need
-to check for any special properties of it, then you can use one of the
-general program-check macros.

-
-Particular Program Checks
--------------------------
-
- These macros check for particular programs--whether they exist, and
-in some cases whether they support certain features.
-
- - Macro: AC_PROG_AWK
- Check for `mawk', `gawk', `nawk', and `awk', in that order, and
- set output variable `AWK' to the first one that is found. It
- tries `mawk' first because that is reported to be the fastest
- implementation.
-
- - Macro: AC_PROG_INSTALL
- Set output variable `INSTALL' to the path of a BSD compatible
- `install' program, if one is found in the current `PATH'.
- Otherwise, set `INSTALL' to `DIR/install-sh -c', checking the
- directories specified to `AC_CONFIG_AUX_DIR' (or its default
- directories) to determine DIR (*note Output::). Also set the
- variables `INSTALL_PROGRAM' and `INSTALL_SCRIPT' to `${INSTALL}'
- and `INSTALL_DATA' to `${INSTALL} -m 644'.
-
- This macro screens out various instances of `install' known not to
- work. It prefers to find a C program rather than a shell script,
- for speed. Instead of `install-sh', it can also use `install.sh',
- but that name is obsolete because some `make' programs have a rule
- that creates `install' from it if there is no `Makefile'.
-
- Autoconf comes with a copy of `install-sh' that you can use. If
- you use `AC_PROG_INSTALL', you must include either `install-sh' or
- `install.sh' in your distribution, or `configure' will produce an
- error message saying it can't find them--even if the system you're
- on has a good `install' program. This check is a safety measure
- to prevent you from accidentally leaving that file out, which
- would prevent your package from installing on systems that don't
- have a BSD-compatible `install' program.
-
- If you need to use your own installation program because it has
- features not found in standard `install' programs, there is no
- reason to use `AC_PROG_INSTALL'; just put the file name of your
- program into your `Makefile.in' files.
-
- - Macro: AC_PROG_LEX
- If `flex' is found, set output variable `LEX' to `flex' and
- `LEXLIB' to `-lfl', if that library is in a standard place.
- Otherwise set `LEX' to `lex' and `LEXLIB' to `-ll'.
-
- Define `YYTEXT_POINTER' if `yytext' is a `char *' instead of a
- `char []'. Also set output variable `LEX_OUTPUT_ROOT' to the base
- of the file name that the lexer generates; usually `lex.yy', but
- sometimes something else. These results vary according to whether
- `lex' or `flex' is being used.
-
- You are encouraged to use Flex in your sources, since it is both
- more pleasant to use than plain Lex and the C source it produces
- is portable. In order to ensure portability, however, you must
- either provide a function `yywrap' or, if you don't use it (e.g.,
- your scanner has no `#include'-like feature), simply include a
- `%noyywrap' statement in the scanner's source. Once this done,
- the scanner is portable (unless _you_ felt free to use nonportable
- constructs) and does not depend on any library. In this case, and
- in this case only, it is suggested that you use this Autoconf
- snippet:
-
- AC_PROG_LEX
- if test "$LEX" != flex; then
- LEX="$SHELL $missing_dir/missing flex"
- AC_SUBST(LEX_OUTPUT_ROOT, lex.yy)
- AC_SUBST(LEXLIB, '')
- fi
-
- The shell script `missing' can be found in the Automake
- distribution.
-
- To ensure backward compatibility, Automake's `AM_PROG_LEX' invokes
- (indirectly) this macro twice, which will cause an annoying but
- benign "`AC_PROG_LEX' invoked multiple times" warning. Future
- versions of Automake will fix this issue, meanwhile, just ignore
- this message.
-
- - Macro: AC_PROG_LN_S
- If `ln -s' works on the current file system (the operating system
- and file system support symbolic links), set the output variable
- `LN_S' to `ln -s'; otherwise, if `ln' works, set `LN_S' to `ln'
- and otherwise set it to `cp -p'.
-
- If you make a link a directory other than the current directory,
- its meaning depends on whether `ln' or `ln -s' is used. To safely
- create links using `$(LN_S)', either find out which form is used
- and adjust the arguments, or always invoke `ln' in the directory
- where the link is to be created.
-
- In other words, it does not work to do:
- $(LN_S) foo /x/bar
-
- Instead, do:
-
- (cd /x && $(LN_S) foo bar)
-
- - Macro: AC_PROG_RANLIB
- Set output variable `RANLIB' to `ranlib' if `ranlib' is found, and
- otherwise to `:' (do nothing).
-
- - Macro: AC_PROG_YACC
- If `bison' is found, set output variable `YACC' to `bison -y'.
- Otherwise, if `byacc' is found, set `YACC' to `byacc'. Otherwise
- set `YACC' to `yacc'.

-Generic Program and File Checks
--------------------------------
-
- These macros are used to find programs not covered by the
-"particular" test macros. If you need to check the behavior of a
-program as well as find out whether it is present, you have to write
-your own test for it (*note Writing Tests::). By default, these macros
-use the environment variable `PATH'. If you need to check for a
-program that might not be in the user's `PATH', you can pass a modified
-path to use instead, like this:
-
- AC_PATH_PROG(INETD, inetd, /usr/libexec/inetd,
- $PATH:/usr/libexec:/usr/sbin:/usr/etc:etc)
-
- You are strongly encouraged to declare the VARIABLE passed to
-`AC_CHECK_PROG' etc. as precious, *Note Setting Output Variables::,
-`AC_ARG_VAR', for more details.
-
- - Macro: AC_CHECK_PROG (VARIABLE, PROG-TO-CHECK-FOR, VALUE-IF-FOUND,
- [VALUE-IF-NOT-FOUND], [PATH], [REJECT])
- Check whether program PROG-TO-CHECK-FOR exists in `PATH'. If it
- is found, set VARIABLE to VALUE-IF-FOUND, otherwise to
- VALUE-IF-NOT-FOUND, if given. Always pass over REJECT (an
- absolute file name) even if it is the first found in the search
- path; in that case, set VARIABLE using the absolute file name of
- the PROG-TO-CHECK-FOR found that is not REJECT. If VARIABLE was
- already set, do nothing. Calls `AC_SUBST' for VARIABLE.
-
- - Macro: AC_CHECK_PROGS (VARIABLE, PROGS-TO-CHECK-FOR,
- [VALUE-IF-NOT-FOUND], [PATH])
- Check for each program in the whitespace-separated list
- PROGS-TO-CHECK-FOR exists on the `PATH'. If it is found, set
- VARIABLE to the name of that program. Otherwise, continue
- checking the next program in the list. If none of the programs in
- the list are found, set VARIABLE to VALUE-IF-NOT-FOUND; if
- VALUE-IF-NOT-FOUND is not specified, the value of VARIABLE is not
- changed. Calls `AC_SUBST' for VARIABLE.
-
- - Macro: AC_CHECK_TOOL (VARIABLE, PROG-TO-CHECK-FOR,
- [VALUE-IF-NOT-FOUND], [PATH])
- Like `AC_CHECK_PROG', but first looks for PROG-TO-CHECK-FOR with a
- prefix of the host type as determined by `AC_CANONICAL_HOST',
- followed by a dash (*note Canonicalizing::). For example, if the
- user runs `configure --host=i386-gnu', then this call:
- AC_CHECK_TOOL(RANLIB, ranlib, :)
-
- sets `RANLIB' to `i386-gnu-ranlib' if that program exists in
- `PATH', or otherwise to `ranlib' if that program exists in `PATH',
- or to `:' if neither program exists.
-
- - Macro: AC_CHECK_TOOLS (VARIABLE, PROGS-TO-CHECK-FOR,
- [VALUE-IF-NOT-FOUND], [PATH])
- Like `AC_CHECK_TOOL', each of the tools in the list
- PROGS-TO-CHECK-FOR are checked with a prefix of the host type as
- determined by `AC_CANONICAL_HOST', followed by a dash (*note
- Canonicalizing::). If none of the tools can be found with a
- prefix, then the first one without a prefix is used. If a tool is
- found, set VARIABLE to the name of that program. If none of the
- tools in the list are found, set VARIABLE to VALUE-IF-NOT-FOUND; if
- VALUE-IF-NOT-FOUND is not specified, the value of VARIABLE is not
- changed. Calls `AC_SUBST' for VARIABLE.
-
- - Macro: AC_PATH_PROG (VARIABLE, PROG-TO-CHECK-FOR,
- [VALUE-IF-NOT-FOUND], [PATH])
- Like `AC_CHECK_PROG', but set VARIABLE to the entire path of
- PROG-TO-CHECK-FOR if found.
-
- - Macro: AC_PATH_PROGS (VARIABLE, PROGS-TO-CHECK-FOR,
- [VALUE-IF-NOT-FOUND], [PATH])
- Like `AC_CHECK_PROGS', but if any of PROGS-TO-CHECK-FOR are found,
- set VARIABLE to the entire path of the program found.
-
- - Macro: AC_PATH_TOOL (VARIABLE, PROG-TO-CHECK-FOR,
- [VALUE-IF-NOT-FOUND], [PATH])
- Like `AC_CHECK_TOOL', but set VARIABLE to the entire path of the
- program if it is found.

-Files
-=====
-
- You might also need to check for the existence of files. Before
-using these macros, ask yourself whether a run time test might not be a
-better solution. Be aware that, like most Autoconf macros, they test a
-feature of the host machine, and therefore, they die when
-cross-compiling.
-
- - Macro: AC_CHECK_FILE (FILE, [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
- Check whether file FILE exists on the native system. If it is
- found, execute ACTION-IF-FOUND, otherwise do ACTION-IF-NOT-FOUND,
- if given.
-
- - Macro: AC_CHECK_FILES (FILES, [ACTION-IF-FOUND],
- [ACTION-IF-NOT-FOUND])
- Executes `AC_CHECK_FILE' once for each file listed in FILES.
- Additionally, defines `HAVE_FILE' (*note Standard Symbols::) for
- each file found.
-
-
-File: autoconf.info, Node: Libraries, Next: Library Functions, Prev: Files, Up: Existing Tests
-
-Library Files
-=============
-
- The following macros check for the presence of certain C, C++ or
-Fortran 77 library archive files.
-
- - Macro: AC_CHECK_LIB (LIBRARY, FUNCTION, [ACTION-IF-FOUND],
- [ACTION-IF-NOT-FOUND], [OTHER-LIBRARIES])
- Depending on the current language(*note Language Choice::), try to
- ensure that the C, C++, or Fortran 77 function FUNCTION is
- available by checking whether a test program can be linked with the
- library LIBRARY to get the function. LIBRARY is the base name of
- the library; e.g., to check for `-lmp', use `mp' as the LIBRARY
- argument.
-
- ACTION-IF-FOUND is a list of shell commands to run if the link
- with the library succeeds; ACTION-IF-NOT-FOUND is a list of shell
- commands to run if the link fails. If ACTION-IF-FOUND is not
- specified, the default action will prepend `-lLIBRARY' to `LIBS'
- and define `HAVE_LIBLIBRARY' (in all capitals). This macro is
- intended to support building of `LIBS' in a right-to-left
- (least-dependent to most-dependent) fashion such that library
- dependencies are satisfied as a natural side-effect of consecutive
- tests. Some linkers are very sensitive to library ordering so the
- order in which `LIBS' is generated is important to reliable
- detection of libraries.
-
- If linking with LIBRARY results in unresolved symbols that would
- be resolved by linking with additional libraries, give those
- libraries as the OTHER-LIBRARIES argument, separated by spaces:
- e.g. `-lXt -lX11'. Otherwise, this macro will fail to detect that
- LIBRARY is present, because linking the test program will always
- fail with unresolved symbols. The OTHER-LIBRARIES argument should
- be limited to cases where it is desirable to test for one library
- in the presence of another that is not already in `LIBS'.
-
- - Macro: AC_SEARCH_LIBS (FUNCTION, SEARCH-LIBS, [ACTION-IF-FOUND],
- [ACTION-IF-NOT-FOUND], [OTHER-LIBRARIES])
- Search for a library defining FUNCTION if it's not already
- available. This equates to calling `AC_TRY_LINK_FUNC' first with
- no libraries, then for each library listed in SEARCH-LIBS.
-
- Add `-lLIBRARY' to `LIBS' for the first library found to contain
- FUNCTION, and run ACTION-IF-FOUND. If the function is not found,
- run ACTION-IF-NOT-FOUND.
-
- If linking with LIBRARY results in unresolved symbols that would
- be resolved by linking with additional libraries, give those
- libraries as the OTHER-LIBRARIES argument, separated by spaces:
- e.g. `-lXt -lX11'. Otherwise, this macro will fail to detect that
- FUNCTION is present, because linking the test program will always
- fail with unresolved symbols.

-
- The following macros check for particular C library functions. If

-and you don't need to check for any special properties of it, then you
-can use one of the general function-check macros.

-Portability of Classical Functions
-----------------------------------
-
- Most usual functions can either be missing, or be buggy, or be
-limited on some architectures. This section tries to make an inventory
-of these portability issues. By definition, this list will always
-require additions, please help us keeping it as complete as possible
-
-`unlink'
- The POSIX spec says that `unlink' causes the given files to be
- removed only after there are no more open file handles for it.
- Not all OS's support this behaviour though. So even on systems
- that provide `unlink', you cannot portably assume it is OK to call
- it on files that are open. For example, on Windows 9x and ME,
- such a call would fail; on DOS it could even lead to file system
- corruption, as the file might end up being written to after the OS
- has removed it.

- Check how to get `alloca'. Tries to get a builtin version by
- checking for `alloca.h' or the predefined C preprocessor macros
- `__GNUC__' and `_AIX'. If this macro finds `alloca.h', it defines
- `HAVE_ALLOCA_H'.
-
- If those attempts fail, it looks for the function in the standard C
- library. If any of those methods succeed, it defines
- `HAVE_ALLOCA'. Otherwise, it sets the output variable `ALLOCA' to
- `alloca.o' and defines `C_ALLOCA' (so programs can periodically
- call `alloca(0)' to garbage collect). This variable is separate
- from `LIBOBJS' so multiple programs can share the value of
- `ALLOCA' without needing to create an actual library, in case only
- some of them use the code in `LIBOBJS'.
-
- This macro does not try to get `alloca' from the System V R3
- `libPW' or the System V R4 `libucb' because those libraries
- contain some incompatible functions that cause trouble. Some
- versions do not even contain `alloca' or contain a buggy version.
- If you still want to use their `alloca', use `ar' to extract
- `alloca.o' from them instead of compiling `alloca.c'.
-
- Source files that use `alloca' should start with a piece of code
- like the following, to declare it properly. In some versions of
- AIX, the declaration of `alloca' must precede everything else
- except for comments and preprocessor directives. The `#pragma'
- directive is indented so that pre-ANSI C compilers will ignore it,
- rather than choke on it.
-
- /* AIX requires this to be the first thing in the file. */
- #ifndef __GNUC__
- # if HAVE_ALLOCA_H
- # include <alloca.h>
- # else
- # ifdef _AIX
- #pragma alloca
- # else
- # ifndef alloca /* predefined by HP cc +Olibcalls */
- char *alloca ();
- # endif
- # endif
- # endif
- #endif
-
- - Macro: AC_FUNC_CHOWN
- If the `chown' function is available and works (in particular, it
- should accept `-1' for `uid' and `gid'), define `HAVE_CHOWN'.
-
- - Macro: AC_FUNC_CLOSEDIR_VOID
- If the `closedir' function does not return a meaningful value,
- define `CLOSEDIR_VOID'. Otherwise, callers ought to check its
- return value for an error indicator.
-
- - Macro: AC_FUNC_ERROR_AT_LINE
- If the `error_at_line' function is not found, require an
- `AC_LIBOBJ' replacement of `error'.
-
- - Macro: AC_FUNC_FNMATCH
- If the `fnmatch' function is available and works (unlike the one on
- Solaris 2.4), define `HAVE_FNMATCH'.
-
- - Macro: AC_FUNC_FORK
- This macro checks for the `fork' and `vfork' functions. If a
- working `fork' is found, define `HAVE_WORKING_FORK'. This macro
- checks whether `fork' is just a stub by trying to run it.
-
- If `vfork.h' is found, define `HAVE_VFORK_H'. If a working `vfork'
- is found, define `HAVE_WORKING_VFORK'. Otherwise, define `vfork'
- to be `fork' for backward compatibility with previous versions of
- `autoconf'. This macro checks for several known errors in
- implementations of `vfork' and considers the system to not have a
- working `vfork' if it detects any of them. It is not considered to
- be an implementation error if a child's invocation of `signal'
- modifies the parent's signal handler, since child processes rarely
- change their signal handlers.
-
- Since this macro defines `vfork' only for backward compatibility
- with previous versions of `autoconf' you're encouraged to define it
- yourself in new code:
- #if !HAVE_WORKING_VFORK
- # define vfork fork
- #endif
-
- - Macro: AC_FUNC_FSEEKO
- If the `fseeko' function is available, define `HAVE_FSEEKO'.
- Define `_LARGEFILE_SOURCE' if necessary.
-
- - Macro: AC_FUNC_GETGROUPS
- If the `getgroups' function is available and works (unlike on
- Ultrix 4.3, where `getgroups (0, 0)' always fails), define
- `HAVE_GETGROUPS'. Set `GETGROUPS_LIBS' to any libraries needed to
- get that function. This macro runs `AC_TYPE_GETGROUPS'.
-
- - Macro: AC_FUNC_GETLOADAVG
- Check how to get the system load averages. If the system has the
- `getloadavg' function, define `HAVE_GETLOADAVG', and set
- `GETLOADAVG_LIBS' to any libraries needed to get that function.
- Also add `GETLOADAVG_LIBS' to `LIBS'.
-
- Otherwise, require an `AC_LIBOBJ' replacement (`getloadavg.c') of
- `getloadavg', and possibly define several other C preprocessor
- macros and output variables:
-
- 1. Define `C_GETLOADAVG'.
-
- 2. Define `SVR4', `DGUX', `UMAX', or `UMAX4_3' if on those
- systems.
-
- 3. If `nlist.h' is found, define `NLIST_STRUCT'.
-
- 4. If `struct nlist' has an `n_un.n_name' member, define
- `HAVE_STRUCT_NLIST_N_UN_N_NAME'. The obsolete symbol
- `NLIST_NAME_UNION' is still defined, but do not depend upon
- it.
-
- 5. Programs may need to be installed setgid (or setuid) for
- `getloadavg' to work. In this case, define
- `GETLOADAVG_PRIVILEGED', set the output variable `NEED_SETGID'
- to `true' (and otherwise to `false'), and set `KMEM_GROUP' to
- the name of the group that should own the installed program.
-
- - Macro: AC_FUNC_GETMNTENT
- Check for `getmntent' in the `sun', `seq', and `gen' libraries,
- for Irix 4, PTX, and Unixware, respectively. Then, if `getmntent'
- is available, define `HAVE_GETMNTENT'.
-
- - Macro: AC_FUNC_GETPGRP
- If `getpgrp' takes no argument (the POSIX.1 version), define
- `GETPGRP_VOID'. Otherwise, it is the BSD version, which takes a
- process ID as an argument. This macro does not check whether
- `getpgrp' exists at all; if you need to work in that situation,
- first call `AC_CHECK_FUNC' for `getpgrp'.
-
- - Macro: AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK
- If `link' is a symbolic link, then `lstat' should treat `link/'
- the same as `link/.'. However, many older `lstat' implementations
- incorrectly ignore trailing slashes.
-
- It is safe to assume that if `lstat' incorrectly ignores trailing
- slashes, then other symbolic-link-aware functions like `unlink'
- and `unlink' also incorrectly ignore trailing slashes.
-
- If `lstat' behaves properly, define
- `LSTAT_FOLLOWS_SLASHED_SYMLINK', otherwise require an `AC_LIBOBJ'
- replacement of `lstat'.
-
- - Macro: AC_FUNC_MALLOC
- If the `malloc' works correctly (`malloc (0)' returns a valid
- pointer), define `HAVE_MALLOC'.
-
- - Macro: AC_FUNC_MEMCMP
- If the `memcmp' function is not available, or does not work on
- 8-bit data (like the one on SunOS 4.1.3), or fails when comparing
- 16 bytes or more and with at least one buffer not starting on a
- 4-byte boundary (such as the one on NeXT x86 OpenStep), require an
- `AC_LIBOBJ' replacement for `memcmp'.
-
- - Macro: AC_FUNC_MKTIME
- If the `mktime' function is not available, or does not work
- correctly, require an `AC_LIBOBJ' replacement for `mktime'.
-
- - Macro: AC_FUNC_MMAP
- If the `mmap' function exists and works correctly, define
- `HAVE_MMAP'. Only checks private fixed mapping of already-mapped
- memory.
-
- - Macro: AC_FUNC_OBSTACK
- If the obstacks are found, define `HAVE_OBSTACK', else require an
- `AC_LIBOBJ' replacement for `obstack'.
-
- - Macro: AC_FUNC_SELECT_ARGTYPES
- Determines the correct type to be passed for each of the `select'
- function's arguments, and defines those types in
- `SELECT_TYPE_ARG1', `SELECT_TYPE_ARG234', and `SELECT_TYPE_ARG5'
- respectively. `SELECT_TYPE_ARG1' defaults to `int',
- `SELECT_TYPE_ARG234' defaults to `int *', and `SELECT_TYPE_ARG5'
- defaults to `struct timeval *'.
-
- - Macro: AC_FUNC_SETPGRP
- If `setpgrp' takes no argument (the POSIX.1 version), define
- `SETPGRP_VOID'. Otherwise, it is the BSD version, which takes two
- process IDs as arguments. This macro does not check whether
- `setpgrp' exists at all; if you need to work in that situation,
- first call `AC_CHECK_FUNC' for `setpgrp'.
-
- - Macro: AC_FUNC_STAT
- - Macro: AC_FUNC_LSTAT
- Determine whether `stat' or `lstat' have the bug that it succeeds
- when given the zero-length file name argument. The `stat' and
- `lstat' from SunOS 4.1.4 and the Hurd (as of 1998-11-01) do this.
-
- If it does, then define `HAVE_STAT_EMPTY_STRING_BUG' (or
- `HAVE_LSTAT_EMPTY_STRING_BUG') and ask for an `AC_LIBOBJ'
- replacement of it.
-
- - Macro: AC_FUNC_SETVBUF_REVERSED
- If `setvbuf' takes the buffering type as its second argument and
- the buffer pointer as the third, instead of the other way around,
- define `SETVBUF_REVERSED'.
-
- - Macro: AC_FUNC_STRCOLL
- If the `strcoll' function exists and works correctly, define
- `HAVE_STRCOLL'. This does a bit more than
- `AC_CHECK_FUNCS(strcoll)', because some systems have incorrect
- definitions of `strcoll' that should not be used.
-
- - Macro: AC_FUNC_STRTOD
- If the `strtod' function does not exist or doesn't work correctly,
- ask for an `AC_LIBOBJ' replacement of `strtod'. In this case,
- because `strtod.c' is likely to need `pow', set the output
- variable `POW_LIB' to the extra library needed.
-
- - Macro: AC_FUNC_STRERROR_R
- If `strerror_r' is available, define `HAVE_STRERROR_R'. If its
- implementation correctly returns a `char *', define
- `HAVE_WORKING_STRERROR_R'. On at least DEC UNIX 4.0[A-D] and HP-UX
- B.10.20, `strerror_r' returns `int'. Actually, this tests only
- whether it returns a scalar or an array, but that should be enough.
- This is used by the common `error.c'.
-
- - Macro: AC_FUNC_STRFTIME
- Check for `strftime' in the `intl' library, for SCO UNIX. Then,
- if `strftime' is available, define `HAVE_STRFTIME'.
-
- - Macro: AC_FUNC_UTIME_NULL
- If `utime(FILE, NULL)' sets FILE's timestamp to the present,
- define `HAVE_UTIME_NULL'.
-
- - Macro: AC_FUNC_VPRINTF
- If `vprintf' is found, define `HAVE_VPRINTF'. Otherwise, if
- `_doprnt' is found, define `HAVE_DOPRNT'. (If `vprintf' is
- available, you may assume that `vfprintf' and `vsprintf' are also
- available.)

-Generic Function Checks
------------------------
-
- These macros are used to find functions not covered by the
-"particular" test macros. If the functions might be in libraries other
-than the default C library, first call `AC_CHECK_LIB' for those
-libraries. If you need to check the behavior of a function as well as
-find out whether it is present, you have to write your own test for it
-(*note Writing Tests::).
-
- - Macro: AC_CHECK_FUNC (FUNCTION, [ACTION-IF-FOUND],
- [ACTION-IF-NOT-FOUND])
- If C function FUNCTION is available, run shell commands
- ACTION-IF-FOUND, otherwise ACTION-IF-NOT-FOUND. If you just want
- to define a symbol if the function is available, consider using
- `AC_CHECK_FUNCS' instead. This macro checks for functions with C
- linkage even when `AC_LANG(C++)' has been called, since C is more
- standardized than C++. (*note Language Choice::, for more
- information about selecting the language for checks.)
-
- - Macro: AC_CHECK_FUNCS (FUNCTION..., [ACTION-IF-FOUND],
- [ACTION-IF-NOT-FOUND])
- For each FUNCTION in the whitespace-separated argument list,
- define `HAVE_FUNCTION' (in all capitals) if it is available. If
- ACTION-IF-FOUND is given, it is additional shell code to execute
- when one of the functions is found. You can give it a value of
- `break' to break out of the loop on the first match. If
- ACTION-IF-NOT-FOUND is given, it is executed when one of the
- functions is not found.
-
- Autoconf follows a philosophy that was formed over the years by those
-who have struggled for portability: isolate the portability issues in
-specific files, and then program as if you were in a POSIX environment.
-Some functions may be missing or unfixable, and your package must be
-ready to replace them.
-
- Use the first three of the following macros to specify a function to
-be replaced, and the last one (`AC_REPLACE_FUNCS') to check for and
-replace the function if needed.
-
- - Macro: AC_LIBOBJ (FUNCTION)
- Specify that `FUNCTION.c' must be included in the executables to
- replace a missing or broken implementation of FUNCTION.
-
- Technically, it adds `FUNCTION.$ac_objext' to the output variable
- `LIBOBJS' and calls `AC_LIBSOURCE' for `FUNCTION.c'. You should
- not directly change `LIBOBJS', since this is not traceable.
-
- - Macro: AC_LIBSOURCE (FILE)
- Specify that FILE might be needed to compile the project. If you
- need to know what files might be needed by a `configure.ac', you
- should trace `AC_LIBSOURCE'. FILE must be a literal.
-
- This macro is called automatically from `AC_LIBOBJ', but you must
- call it explicitly if you pass a shell variable to `AC_LIBOBJ'. In
- that case, since shell variables cannot be traced statically, you
- must pass to `AC_LIBSOURCE' any possible files that the shell
- variable might cause `AC_LIBOBJ' to need. For example, if you
- want to pass a variable `$foo_or_bar' to `AC_LIBOBJ' that holds
- either `"foo"' or `"bar"', you should do:
-
- AC_LIBSOURCE(foo.c)
- AC_LIBSOURCE(bar.c)
- AC_LIBOBJ($foo_or_bar)
-
- There is usually a way to avoid this, however, and you are
- encouraged to simply call `AC_LIBOBJ' with literal arguments.
-
- Note that this macro replaces the obsolete `AC_LIBOBJ_DECL', with
- slightly different semantics: the old macro took the function name,
- e.g. `foo', as its argument rather than the file name.
-
- - Macro: AC_LIBSOURCES (FILES)
- Like `AC_LIBSOURCE', but accepts one or more FILES in a
- comma-separated M4 list. Thus, the above example might be
- rewritten:
-
- AC_LIBSOURCES([foo.c, bar.c])
- AC_LIBOBJ($foo_or_bar)
-
- - Macro: AC_REPLACE_FUNCS (FUNCTION...)
- Like `AC_CHECK_FUNCS', but uses `AC_LIBOBJ(FUNCTION)' as
- ACTION-IF-NOT-FOUND. You can declare your replacement function by
- enclosing the prototype in `#if !HAVE_FUNCTION'. If the system
- has the function, it probably declares it in a header file you
- should be including, so you shouldn't redeclare it lest your
- declaration conflict.

-Header Files
-============
-
- The following macros check for the presence of certain C header
-files. If there is no macro specifically defined to check for a header
-file you need, and you don't need to check for any special properties of
-it, then you can use one of the general header-file check macros.

-* Generic Headers:: How to find other headers
-
-
-File: autoconf.info, Node: Particular Headers, Next: Generic Headers, Prev: Header Files, Up: Header Files
-
-Particular Header Checks
-------------------------
-
- These macros check for particular system header files--whether they
-exist, and in some cases whether they declare certain symbols.
-
- - Macro: AC_HEADER_DIRENT
- Check for the following header files. For the first one that is
- found and defines `DIR', define the listed C preprocessor macro:
-
- `dirent.h' `HAVE_DIRENT_H'
- `sys/ndir.h' `HAVE_SYS_NDIR_H'
- `sys/dir.h' `HAVE_SYS_DIR_H'
- `ndir.h' `HAVE_NDIR_H'
-
- The directory-library declarations in your source code should look
- something like the following:
-
- #if HAVE_DIRENT_H
- # include <dirent.h>
- # define NAMLEN(dirent) strlen((dirent)->d_name)
- #else
- # define dirent direct
- # define NAMLEN(dirent) (dirent)->d_namlen
- # if HAVE_SYS_NDIR_H
- # include <sys/ndir.h>
- # endif
- # if HAVE_SYS_DIR_H
- # include <sys/dir.h>
- # endif
- # if HAVE_NDIR_H
- # include <ndir.h>
- # endif
- #endif
-
- Using the above declarations, the program would declare variables
- to be of type `struct dirent', not `struct direct', and would
- access the length of a directory entry name by passing a pointer
- to a `struct dirent' to the `NAMLEN' macro.
-
- This macro also checks for the SCO Xenix `dir' and `x' libraries.
-
- - Macro: AC_HEADER_MAJOR
- If `sys/types.h' does not define `major', `minor', and `makedev',
- but `sys/mkdev.h' does, define `MAJOR_IN_MKDEV'; otherwise, if
- `sys/sysmacros.h' does, define `MAJOR_IN_SYSMACROS'.
-
- - Macro: AC_HEADER_STAT
- If the macros `S_ISDIR', `S_ISREG' et al. defined in `sys/stat.h'
- do not work properly (returning false positives), define
- `STAT_MACROS_BROKEN'. This is the case on Tektronix UTekV, Amdahl
- UTS and Motorola System V/88.
-
- - Macro: AC_HEADER_STDC
- Define `STDC_HEADERS' if the system has ANSI C header files.
- Specifically, this macro checks for `stdlib.h', `stdarg.h',
- `string.h', and `float.h'; if the system has those, it probably
- has the rest of the ANSI C header files. This macro also checks
- whether `string.h' declares `memchr' (and thus presumably the
- other `mem' functions), whether `stdlib.h' declare `free' (and
- thus presumably `malloc' and other related functions), and whether
- the `ctype.h' macros work on characters with the high bit set, as
- ANSI C requires.
-
- Use `STDC_HEADERS' instead of `__STDC__' to determine whether the
- system has ANSI-compliant header files (and probably C library
- functions) because many systems that have GCC do not have ANSI C
- header files.
-
- On systems without ANSI C headers, there is so much variation that
- it is probably easier to declare the functions you use than to
- figure out exactly what the system header files declare. Some
- systems contain a mix of functions ANSI and BSD; some are mostly
- ANSI but lack `memmove'; some define the BSD functions as macros in
- `string.h' or `strings.h'; some have only the BSD functions but
- `string.h'; some declare the memory functions in `memory.h', some
- in `string.h'; etc. It is probably sufficient to check for one
- string function and one memory function; if the library has the
- ANSI versions of those then it probably has most of the others.
- If you put the following in `configure.ac':
-
- AC_HEADER_STDC
- AC_CHECK_FUNCS(strchr memcpy)
-
- then, in your code, you can put declarations like this:
-
- #if STDC_HEADERS
- # include <string.h>
- #else
- # if !HAVE_STRCHR
- # define strchr index
- # define strrchr rindex
- # endif
- char *strchr (), *strrchr ();
- # if !HAVE_MEMCPY
- # define memcpy(d, s, n) bcopy ((s), (d), (n))
- # define memmove(d, s, n) bcopy ((s), (d), (n))
- # endif
- #endif
-
- If you use a function like `memchr', `memset', `strtok', or
- `strspn', which have no BSD equivalent, then macros won't suffice;
- you must provide an implementation of each function. An easy way
- to incorporate your implementations only when needed (since the
- ones in system C libraries may be hand optimized) is to, taking
- `memchr' for example, put it in `memchr.c' and use
- `AC_REPLACE_FUNCS(memchr)'.
-
- - Macro: AC_HEADER_SYS_WAIT
- If `sys/wait.h' exists and is compatible with POSIX.1, define
- `HAVE_SYS_WAIT_H'. Incompatibility can occur if `sys/wait.h' does
- not exist, or if it uses the old BSD `union wait' instead of `int'
- to store a status value. If `sys/wait.h' is not POSIX.1
- compatible, then instead of including it, define the POSIX.1
- macros with their usual interpretations. Here is an example:
-
- #include <sys/types.h>
- #if HAVE_SYS_WAIT_H
- # include <sys/wait.h>
- #endif
- #ifndef WEXITSTATUS
- # define WEXITSTATUS(stat_val) ((unsigned)(stat_val) >> 8)
- #endif
- #ifndef WIFEXITED
- # define WIFEXITED(stat_val) (((stat_val) & 255) == 0)
- #endif
-
- `_POSIX_VERSION' is defined when `unistd.h' is included on POSIX.1
-systems. If there is no `unistd.h', it is definitely not a POSIX.1
-system. However, some non-POSIX.1 systems do have `unistd.h'.
-
- The way to check if the system supports POSIX.1 is:
-
- #if HAVE_UNISTD_H
- # include <sys/types.h>
- # include <unistd.h>
- #endif
-
- #ifdef _POSIX_VERSION
- /* Code for POSIX.1 systems. */
- #endif
-
- - Macro: AC_HEADER_TIME
- If a program may include both `time.h' and `sys/time.h', define
- `TIME_WITH_SYS_TIME'. On some older systems, `sys/time.h'
- includes `time.h', but `time.h' is not protected against multiple
- inclusion, so programs should not explicitly include both files.
- This macro is useful in programs that use, for example, `struct
- timeval' or `struct timezone' as well as `struct tm'. It is best
- used in conjunction with `HAVE_SYS_TIME_H', which can be checked
- for using `AC_CHECK_HEADERS(sys/time.h)'.
-
- #if TIME_WITH_SYS_TIME
- # include <sys/time.h>
- # include <time.h>
- #else
- # if HAVE_SYS_TIME_H
- # include <sys/time.h>
- # else
- # include <time.h>
- # endif
- #endif
-
- - Macro: AC_HEADER_TIOCGWINSZ
- If the use of `TIOCGWINSZ' requires `<sys/ioctl.h>', then define
- `GWINSZ_IN_SYS_IOCTL'. Otherwise `TIOCGWINSZ' can be found in
- `<termios.h>'.
-
- Use:
-
- #if HAVE_TERMIOS_H
- # include <termios.h>
- #endif
-
- #if GWINSZ_IN_SYS_IOCTL
- # include <sys/ioctl.h>
- #endif

-Generic Header Checks
----------------------
-
- These macros are used to find system header files not covered by the
-"particular" test macros. If you need to check the contents of a header
-as well as find out whether it is present, you have to write your own
-test for it (*note Writing Tests::).
-
- - Macro: AC_CHECK_HEADER (HEADER-FILE, [ACTION-IF-FOUND],
- [ACTION-IF-NOT-FOUND], [INCLUDES])
- If the system header file HEADER-FILE is usable, execute shell
- commands ACTION-IF-FOUND, otherwise execute ACTION-IF-NOT-FOUND.
- If you just want to define a symbol if the header file is
- available, consider using `AC_CHECK_HEADERS' instead.
-
- The meaning of "usable" depends upon the content of INCLUDES:
-
- if INCLUDES is empty
- check whether
-
- HEADER-FILE
-
- can be _preprocessed_ without error.
-
- if INCLUDE is set
- Check whether
-
- INCLUDES
- #include <HEADER-FILE>
-
- can be _compiled_ without error. You may use
- `AC_CHECK_HEADER' (and `AC_CHECK_HEADERS') to check whether
- two headers are compatible.
-
- You may pass any kind of dummy content for INCLUDES, such as a
- single space, a comment, to check whether HEADER-FILE compiles
- with success.
-
- - Macro: AC_CHECK_HEADERS (HEADER-FILE..., [ACTION-IF-FOUND],
- [ACTION-IF-NOT-FOUND], [INCLUDES])
- For each given system header file HEADER-FILE in the
- whitespace-separated argument list that exists, define
- `HAVE_HEADER-FILE' (in all capitals). If ACTION-IF-FOUND is
- given, it is additional shell code to execute when one of the
- header files is found. You can give it a value of `break' to
- break out of the loop on the first match. If ACTION-IF-NOT-FOUND
- is given, it is executed when one of the header files is not found.
-
- Be sure to read the documentation of `AC_CHECK_HEADER' to
- understand the influence of INCLUDES.

-Declarations
-============
-
- The following macros check for the declaration of variables and
-functions. If there is no macro specifically defined to check for a
-symbol you need, then you can use the general macros (*note Generic
-Declarations::) or, for more complex tests, you may use
-`AC_TRY_COMPILE' (*note Examining Syntax::).

-Particular Declaration Checks
------------------------------
-
- The following macros check for certain declarations.
-
- - Macro: AC_DECL_SYS_SIGLIST
- Define `SYS_SIGLIST_DECLARED' if the variable `sys_siglist' is
- declared in a system header file, either `signal.h' or `unistd.h'.

-
-File: autoconf.info, Node: Generic Declarations, Prev: Particular Declarations, Up: Declarations
-
-Generic Declaration Checks
---------------------------
-
- These macros are used to find declarations not covered by the
-"particular" test macros.
-
- - Macro: AC_CHECK_DECL (SYMBOL, [ACTION-IF-FOUND],
- [ACTION-IF-NOT-FOUND], [INCLUDES])
- If SYMBOL (a function or a variable) is not declared in INCLUDES
- and a declaration is needed, run the shell commands
- ACTION-IF-NOT-FOUND, otherwise ACTION-IF-FOUND. If no INCLUDES
- are specified, the default includes are used (*note Default
- Includes::).
-
- This macro actually tests whether it is valid to use SYMBOL as an
- r-value, not if it is really declared, because it is much safer to
- avoid introducing extra declarations when they are not needed.
-
- - Macro: AC_CHECK_DECLS (SYMBOLS, [ACTION-IF-FOUND],
- [ACTION-IF-NOT-FOUND], [INCLUDES])
- For each of the SYMBOLS (_comma_-separated list), define
- `HAVE_DECL_SYMBOL' (in all capitals) to `1' if SYMBOL is declared,
- otherwise to `0'. If ACTION-IF-NOT-FOUND is given, it is
- additional shell code to execute when one of the function
- declarations is needed, otherwise ACTION-IF-FOUND is executed.
-
- This macro uses an m4 list as first argument:
- AC_CHECK_DECLS(strdup)
- AC_CHECK_DECLS([strlen])
- AC_CHECK_DECLS([malloc, realloc, calloc, free])
-
- Unlike the other `AC_CHECK_*S' macros, when a SYMBOL is not
- declared, `HAVE_DECL_SYMBOL' is defined to `0' instead of leaving
- `HAVE_DECL_SYMBOL' undeclared. When you are _sure_ that the check
- was performed, use `HAVE_DECL_SYMBOL' just like any other result
- of Autoconf:
-
- #if !HAVE_DECL_SYMBOL
- extern char *symbol;
- #endif
-
- If the test may have not been performed, however, because it is
- safer _not_ to declare a symbol than to use a declaration that
- conflicts with the system's one, you should use:
-
- #if defined HAVE_DECL_MALLOC && !HAVE_DECL_MALLOC
- char *malloc (size_t *s);
- #endif
-
- You fall into the second category only in extreme situations:
- either your files may be used without being configured, or they
- are used during the configuration. In most cases the traditional
- approach is enough.

-==========
-
- The following macros check for the presence of certain members in C
-structures. If there is no macro specifically defined to check for a
-member you need, then you can use the general structure-member macro
-(*note Generic Structures::) or, for more complex tests, you may use
-`AC_TRY_COMPILE' (*note Examining Syntax::).

-Particular Structure Checks
----------------------------
-
- The following macros check for certain structures or structure
-members.
-
- - Macro: AC_STRUCT_ST_BLKSIZE
- If `struct stat' contains an `st_blksize' member, define
- `HAVE_STRUCT_STAT_ST_BLKSIZE'. The former name, `HAVE_ST_BLKSIZE'
- is to be avoided, as its support will cease in the future. This
- macro is obsoleted, and should be replaced by
-
- AC_CHECK_MEMBERS([struct stat.st_blksize])
-
- - Macro: AC_STRUCT_ST_BLOCKS
- If `struct stat' contains an `st_blocks' member, define
- `HAVE_STRUCT STAT_ST_BLOCKS'. Otherwise, require an `AC_LIBOBJ'
- replacement of `fileblocks'. The former name, `HAVE_ST_BLOCKS' is
- to be avoided, as its support will cease in the future.
-
- - Macro: AC_STRUCT_ST_RDEV
- If `struct stat' contains an `st_rdev' member, define
- `HAVE_STRUCT_STAT_ST_RDEV'. The former name for this macro,
- `HAVE_ST_RDEV', is to be avoided as it will cease to be supported
- in the future. Actually, even the new macro is obsolete, and
- should be replaced by:
- AC_CHECK_MEMBERS([struct stat.st_rdev])
-
- - Macro: AC_STRUCT_TM
- If `time.h' does not define `struct tm', define `TM_IN_SYS_TIME',
- which means that including `sys/time.h' had better define `struct
- tm'.
-
- - Macro: AC_STRUCT_TIMEZONE
- Figure out how to get the current timezone. If `struct tm' has a
- `tm_zone' member, define `HAVE_STRUCT_TM_TM_ZONE' (and the
- obsoleted `HAVE_TM_ZONE'). Otherwise, if the external array
- `tzname' is found, define `HAVE_TZNAME'.

-Generic Structure Checks
-------------------------
-
- These macros are used to find structure members not covered by the
-"particular" test macros.
-
- - Macro: AC_CHECK_MEMBER (AGGREGATE.MEMBER, [ACTION-IF-FOUND],
- [ACTION-IF-NOT-FOUND], [INCLUDES])
- Check whether MEMBER is a member of the aggregate AGGREGATE. If
- no INCLUDES are specified, the default includes are used (*note
- Default Includes::).
-
- AC_CHECK_MEMBER(struct passwd.pw_gecos,,
- [AC_MSG_ERROR([We need `passwd.pw_gecos'!])],
- [#include <pwd.h>])
-
- You can use this macro for sub-members:
-
- AC_CHECK_MEMBER(struct top.middle.bot)
-
- - Macro: AC_CHECK_MEMBERS (MEMBERS, [ACTION-IF-FOUND],
- [ACTION-IF-NOT-FOUND], [INCLUDES])
- Check for the existence of each `AGGREGATE.MEMBER' of MEMBERS
- using the previous macro. When MEMBER belongs to AGGREGATE,
- define `HAVE_AGGREGATE_MEMBER' (in all capitals, with spaces and
- dots replaced by underscores).
-
- This macro uses m4 lists:
- AC_CHECK_MEMBERS([struct stat.st_rdev, struct stat.st_blksize])

-Types
-=====
-
- The following macros check for C types, either builtin or typedefs.

-Particular Type Checks
-----------------------
-
- These macros check for particular C types in `sys/types.h',
-`stdlib.h' and others, if they exist.
-
- - Macro: AC_TYPE_GETGROUPS
- Define `GETGROUPS_T' to be whichever of `gid_t' or `int' is the
- base type of the array argument to `getgroups'.
-
- - Macro: AC_TYPE_MODE_T
- Equivalent to `AC_CHECK_TYPE(mode_t, int)'.

-
- - Macro: AC_TYPE_PID_T
- Equivalent to `AC_CHECK_TYPE(pid_t, int)'.
-
- - Macro: AC_TYPE_SIGNAL
- If `signal.h' declares `signal' as returning a pointer to a
- function returning `void', define `RETSIGTYPE' to be `void';
- otherwise, define it to be `int'.
-
- Define signal handlers as returning type `RETSIGTYPE':
-
- RETSIGTYPE
- hup_handler ()
- {
- ...
- }
-
- - Macro: AC_TYPE_SIZE_T
- Equivalent to `AC_CHECK_TYPE(size_t, unsigned)'.

- to be `int'.

-Generic Type Checks
--------------------
-
- These macros are used to check for types not covered by the
-"particular" test macros.
-
- - Macro: AC_CHECK_TYPE (TYPE, [ACTION-IF-FOUND],
- [ACTION-IF-NOT-FOUND], [INCLUDES])
- Check whether TYPE is defined. It may be a compiler builtin type
- or defined by the [INCLUDES] (*note Default Includes::).
-
- - Macro: AC_CHECK_TYPES (TYPES, [ACTION-IF-FOUND],
- [ACTION-IF-NOT-FOUND], [INCLUDES])
- For each TYPE of the TYPES that is defined, define `HAVE_TYPE' (in
- all capitals). If no INCLUDES are specified, the default includes
- are used (*note Default Includes::). If ACTION-IF-FOUND is given,
- it is additional shell code to execute when one of the types is
- found. If ACTION-IF-NOT-FOUND is given, it is executed when one
- of the types is not found.
-
- This macro uses m4 lists:
- AC_CHECK_TYPES(ptrdiff_t)
- AC_CHECK_TYPES([unsigned long long, uintmax_t])
-
-
- Autoconf, up to 2.13, used to provide to another version of
-`AC_CHECK_TYPE', broken by design. In order to keep backward
-compatibility, a simple heuristics, quite safe but not totally, is
-implemented. In case of doubt, read the documentation of the former
-`AC_CHECK_TYPE', see *Note Obsolete Macros::.

-Compilers and Preprocessors
-===========================
-
- All the tests for compilers (`AC_PROG_CC', `AC_PROG_CXX',
-`AC_PROG_F77') define the output variable `EXEEXT' based on the output
-of the compiler, typically to the empty string if Unix and `.exe' if
-Win32 or OS/2.
-
- They also define the output variable `OBJEXT' based on the output of
-the compiler, after .c files have been excluded, typically to `o' if
-Unix, `obj' if Win32.
-
- If the compiler being used does not produce executables, they fail.
-If the executables can't be run, and cross-compilation is not enabled,
-they fail too. *Note Manual Configuration::, for more on support for
-cross compiling.

-Generic Compiler Characteristics
---------------------------------
-
- - Macro: AC_CHECK_SIZEOF (TYPE, [UNUSED], [INCLUDES])
- Define `SIZEOF_TYPE' (*note Standard Symbols::) to be the size in
- bytes of TYPE. If `type' is unknown, it gets a size of 0. If no
- INCLUDES are specified, the default includes are used (*note
- Default Includes::). If you provide INCLUDE, make sure to include
- `stdio.h' which is required for this macro to run.
-
- This macro now works even when cross-compiling. The UNUSED
- argument was used when cross-compiling.
-
- For example, the call
-
- AC_CHECK_SIZEOF(int *)
-
- defines `SIZEOF_INT_P' to be 8 on DEC Alpha AXP systems.

-
-C Compiler Characteristics
---------------------------
-
- - Macro: AC_PROG_CC ([COMPILER-SEARCH-LIST])
- Determine a C compiler to use. If `CC' is not already set in the
- environment, check for `gcc' and `cc', then for other C compilers.
- Set output variable `CC' to the name of the compiler found.
-
- This macro may, however, be invoked with an optional first argument
- which, if specified, must be a space separated list of C compilers
- to search for. This just gives the user an opportunity to specify
- an alternative search list for the C compiler. For example, if
- you didn't like the default order, then you could invoke
- `AC_PROG_CC' like this:
-
- AC_PROG_CC(cl egcs gcc cc)
-
- If using the GNU C compiler, set shell variable `GCC' to `yes'.
- If output variable `CFLAGS' was not already set, set it to `-g
- -O2' for the GNU C compiler (`-O2' on systems where GCC does not
- accept `-g'), or `-g' for other compilers.
-
- - Macro: AC_PROG_CC_C_O
- If the C compiler does not accept the `-c' and `-o' options
- simultaneously, define `NO_MINUS_C_MINUS_O'. This macro actually
- tests both the compiler found by `AC_PROG_CC', and, if different,
- the first `cc' in the path. The test fails if one fails. This
- macro was created for GNU Make to choose the default C compilation
- rule.
-
- - Macro: AC_PROG_CC_STDC
- If the C compiler is not in ANSI C mode by default, try to add an
- option to output variable `CC' to make it so. This macro tries
- various options that select ANSI C on some system or another. It
- considers the compiler to be in ANSI C mode if it handles function
- prototypes correctly.
-
- If you use this macro, you should check after calling it whether
- the C compiler has been set to accept ANSI C; if not, the shell
- variable `ac_cv_prog_cc_stdc' is set to `no'. If you wrote your
- source code in ANSI C, you can make an un-ANSIfied copy of it by
- using the program `ansi2knr', which comes with Automake.
-
- - Macro: AC_PROG_CPP
- Set output variable `CPP' to a command that runs the C
- preprocessor. If `$CC -E' doesn't work, `/lib/cpp' is used. It
- is only portable to run `CPP' on files with a `.c' extension.
-
- If the current language is C (*note Language Choice::), many of the
- specific test macros use the value of `CPP' indirectly by calling
- `AC_TRY_CPP', `AC_CHECK_HEADER', `AC_EGREP_HEADER', or
- `AC_EGREP_CPP'.
-
- Some preprocessors don't indicate missing include files by the
- error status. For such preprocessors an internal variable is set
- that causes other macros to check the standard error from the
- preprocessor and consider the test failed if any warnings have
- been reported.
-
- The following macros check for C compiler or machine architecture
-features. To check for characteristics not listed here, use
-`AC_TRY_COMPILE' (*note Examining Syntax::) or `AC_TRY_RUN' (*note Run
-Time::)
-
- - Macro: AC_C_BIGENDIAN
- If words are stored with the most significant byte first (like
- Motorola and SPARC, but not Intel and VAX, CPUs), define
- `WORDS_BIGENDIAN'.
-
- - Macro: AC_C_CONST
- If the C compiler does not fully support the ANSI C qualifier
- `const', define `const' to be empty. Some C compilers that do not
- define `__STDC__' do support `const'; some compilers that define
- `__STDC__' do not completely support `const'. Programs can simply
- use `const' as if every C compiler supported it; for those that
- don't, the `Makefile' or configuration header file will define it
- as empty.
-
- Occasionally installers use a C++ compiler to compile C code,
- typically because they lack a C compiler. This causes problems
- with `const', because C and C++ treat `const' differently. For
- example:
-
- const int foo;
-
- is valid in C but not in C++. These differences unfortunately
- cannot be papered over by defining `const' to be empty.
-
- If `autoconf' detects this situation, it leaves `const' alone, as
- this generally yields better results in practice. However, using a
- C++ compiler to compile C code is not recommended or supported, and
- installers who run into trouble in this area should get a C
- compiler like GCC to compile their C code.
-
- - Macro: AC_C_VOLATILE
- If the C compiler does not understand the keyword `volatile',
- define `volatile' to be empty. Programs can simply use `volatile'
- as if every C compiler supported it; for those that do not, the
- `Makefile' or configuration header will define it as empty.
-
- If the correctness of your program depends on the semantics of
- `volatile', simply defining it to be empty does, in a sense, break
- your code. However, given that the compiler does not support
- `volatile', you are at its mercy anyway. At least your program
- will compile, when it wouldn't before.
-
- In general, the `volatile' keyword is a feature of ANSI C, so you
- might expect that `volatile' is available only when `__STDC__' is
- defined. However, Ultrix 4.3's native compiler does support
- volatile, but does not defined `__STDC__'.
-
- - Macro: AC_C_INLINE
- If the C compiler supports the keyword `inline', do nothing.
- Otherwise define `inline' to `__inline__' or `__inline' if it
- accepts one of those, otherwise define `inline' to be empty.
-
- - Macro: AC_C_CHAR_UNSIGNED
- If the C type `char' is unsigned, define `__CHAR_UNSIGNED__',
- unless the C compiler predefines it.
-
- - Macro: AC_C_LONG_DOUBLE
- If the C compiler supports the `long double' type, define
- `HAVE_LONG_DOUBLE'. Some C compilers that do not define
- `__STDC__' do support the `long double' type; some compilers that
- define `__STDC__' do not support `long double'.
-
- - Macro: AC_C_STRINGIZE
- If the C preprocessor supports the stringizing operator, define
- `HAVE_STRINGIZE'. The stringizing operator is `#' and is found in
- macros such as this:
-
- #define x(y) #y
-
- - Macro: AC_C_PROTOTYPES
- Check to see if function prototypes are understood by the
- compiler. If so, define `PROTOTYPES'. In the case the compiler
- does not handle prototypes, you should use `ansi2knr', which comes
- with the Automake distribution, to unprotoize function
- definitions. For function prototypes, you should first define
- `PARAMS':
-
- #ifndef PARAMS
- # if PROTOTYPES
- # define PARAMS(protos) protos
- # else /* no PROTOTYPES */
- # define PARAMS(protos) ()
- # endif /* no PROTOTYPES */
- #endif
-
- then use it this way:
-
- size_t my_strlen PARAMS ((const char *));
-
- - Macro: AC_PROG_GCC_TRADITIONAL
- Add `-traditional' to output variable `CC' if using the GNU C
- compiler and `ioctl' does not work properly without
- `-traditional'. That usually happens when the fixed header files
- have not been installed on an old system. Since recent versions
- of the GNU C compiler fix the header files automatically when
- installed, this is becoming a less prevalent problem.

-C++ Compiler Characteristics
-----------------------------
-
- - Macro: AC_PROG_CXX ([COMPILER-SEARCH-LIST])
- Determine a C++ compiler to use. Check if the environment variable
- `CXX' or `CCC' (in that order) is set; if so, then set output
- variable `CXX' to its value.
-
- Otherwise, if the macro is invoked without an argument, then
- search for a C++ compiler under the likely names (first `g++' and
- `c++' then other names). If none of those checks succeed, then as
- a last resort set `CXX' to `g++'.
-
- This macro may, however, be invoked with an optional first argument
- which, if specified, must be a space separated list of C++
- compilers to search for. This just gives the user an opportunity
- to specify an alternative search list for the C++ compiler. For
- example, if you didn't like the default order, then you could
- invoke `AC_PROG_CXX' like this:
-
- AC_PROG_CXX(cl KCC CC cxx cc++ xlC aCC c++ g++ egcs gcc)
-
- If using the GNU C++ compiler, set shell variable `GXX' to `yes'.
- If output variable `CXXFLAGS' was not already set, set it to `-g
- -O2' for the GNU C++ compiler (`-O2' on systems where G++ does not
- accept `-g'), or `-g' for other compilers.
-
- - Macro: AC_PROG_CXXCPP
- Set output variable `CXXCPP' to a command that runs the C++
- preprocessor. If `$CXX -E' doesn't work, `/lib/cpp' is used. It
- is only portable to run `CXXCPP' on files with a `.c', `.C', or
- `.cc' extension.
-
- If the current language is C++ (*note Language Choice::), many of
- the specific test macros use the value of `CXXCPP' indirectly by
- calling `AC_TRY_CPP', `AC_CHECK_HEADER', `AC_EGREP_HEADER', or
- `AC_EGREP_CPP'.
-
- Some preprocessors don't indicate missing include files by the
- error status. For such preprocessors an internal variable is set
- that causes other macros to check the standard error from the
- preprocessor and consider the test failed if any warnings have
- been reported. However, it is not known whether such broken
- preprocessors exist for C++.

-
-Fortran 77 Compiler Characteristics
------------------------------------
-
- - Macro: AC_PROG_F77 ([COMPILER-SEARCH-LIST])
- Determine a Fortran 77 compiler to use. If `F77' is not already
- set in the environment, then check for `g77' and `f77', and then
- some other names. Set the output variable `F77' to the name of
- the compiler found.
-
- This macro may, however, be invoked with an optional first argument
- which, if specified, must be a space separated list of Fortran 77
- compilers to search for. This just gives the user an opportunity
- to specify an alternative search list for the Fortran 77 compiler.
- For example, if you didn't like the default order, then you could
- invoke `AC_PROG_F77' like this:
-
- AC_PROG_F77(fl32 f77 fort77 xlf cf77 g77 f90 xlf90)
-
- If using `g77' (the GNU Fortran 77 compiler), then `AC_PROG_F77'
- will set the shell variable `G77' to `yes'. If the output
- variable `FFLAGS' was not already set in the environment, then set
- it to `-g -02' for `g77' (or `-O2' where `g77' does not accept
- `-g'). Otherwise, set `FFLAGS' to `-g' for all other Fortran 77
- compilers.
-
- - Macro: AC_PROG_F77_C_O
- Test if the Fortran 77 compiler accepts the options `-c' and `-o'
- simultaneously, and define `F77_NO_MINUS_C_MINUS_O' if it does not.
-
- The following macros check for Fortran 77 compiler characteristics.
-To check for characteristics not listed here, use `AC_TRY_COMPILE'
-(*note Examining Syntax::) or `AC_TRY_RUN' (*note Run Time::), making
-sure to first set the current language to Fortran 77 `AC_LANG(Fortran
-77)' (*note Language Choice::).
-
- - Macro: AC_F77_LIBRARY_LDFLAGS
- Determine the linker flags (e.g. `-L' and `-l') for the "Fortran
- 77 intrinsic and run-time libraries" that are required to
- successfully link a Fortran 77 program or shared library. The
- output variable `FLIBS' is set to these flags.
-
- This macro is intended to be used in those situations when it is
- necessary to mix, e.g. C++ and Fortran 77 source code into a single
- program or shared library (*note Mixing Fortran 77 With C and C++:
- (automake)Mixing Fortran 77 With C and C++.).
-
- For example, if object files from a C++ and Fortran 77 compiler
- must be linked together, then the C++ compiler/linker must be used
- for linking (since special C++-ish things need to happen at link
- time like calling global constructors, instantiating templates,
- enabling exception support, etc.).
-
- However, the Fortran 77 intrinsic and run-time libraries must be
- linked in as well, but the C++ compiler/linker doesn't know by
- default how to add these Fortran 77 libraries. Hence, the macro
- `AC_F77_LIBRARY_LDFLAGS' was created to determine these Fortran 77
- libraries.
-
- The macro `AC_F77_DUMMY_MAIN' or `AC_F77_MAIN' will probably also
- be necessary to link C/C++ with Fortran; see below.
-
- - Macro: AC_F77_DUMMY_MAIN ([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
- With many compilers, the Fortran libraries detected by
- `AC_F77_LIBRARY_LDFLAGS' provide their own `main' entry function
- that initializes things like Fortran I/O, and which then calls a
- user-provided entry function named e.g. `MAIN__' to run the user's
- program. The `AC_F77_DUMMY_MAIN' or `AC_F77_MAIN' macro figures
- out how to deal with this interaction.
-
- When using Fortran for purely numerical functions (no I/O,
- etcetera), users often prefer to provide their own `main' and skip
- the Fortran library initializations. In this case, however, one
- may still need to provide a dummy `MAIN__' routine in order to
- prevent linking errors on some systems. `AC_F77_DUMMY_MAIN'
- detects whether any such routine is _required_ for linking, and
- what its name is; the shell variable `F77_DUMMY_MAIN' holds this
- name, `unknown' when no solution was found, and `none' when no
- such dummy main is needed.
-
- By default, ACTION-IF-FOUND defines `F77_DUMMY_MAIN' to the name
- of this routine (e.g. `MAIN__') _if_ it is required.
- [ACTION-IF-NOT-FOUND] defaults to exiting with an error.
-
- In order to link with Fortran routines, the user's C/C++ program
- should then include the following code to define the dummy main if
- it is needed:
-
- #ifdef F77_DUMMY_MAIN
- # ifdef __cplusplus
- extern "C"
- # endif
- int F77_DUMMY_MAIN() { return 1; }
- #endif
-
- Note that `AC_F77_DUMMY_MAIN' is called automatically from
- `AC_F77_WRAPPERS'; there is generally no need to call it explicitly
- unless one wants to change the default actions.
-
- - Macro: AC_F77_MAIN
- As discussed above for `AC_F77_DUMMY_MAIN', many Fortran libraries
- allow you to provide an entry point called e.g. `MAIN__' instead of
- the usual `main', which is then called by a `main' function in the
- Fortran libraries that initializes things like Fortran I/O. The
- `AC_F77_MAIN' macro detects whether it is _possible_ to utilize
- such an alternate main function, and defines `F77_MAIN' to the
- name of the function. (If no alternate main function name is
- found, `F77_MAIN' is simply defined to `main'.)
-
- Thus, when calling Fortran routines from C that perform things
- like I/O, one should use this macro and name the "main" function
- `F77_MAIN' instead of `main'.
-
- - Macro: AC_F77_WRAPPERS
- Defines C macros `F77_FUNC(name,NAME)' and `F77_FUNC_(name,NAME)'
- to properly mangle the names of C/C++ identifiers, and identifiers
- with underscores, respectively, so that they match the
- name-mangling scheme used by the Fortran 77 compiler.
-
- Fortran 77 is case-insensitive, and in order to achieve this the
- Fortran 77 compiler converts all identifiers into a canonical case
- and format. To call a Fortran 77 subroutine from C or to write a
- C function that is callable from Fortran 77, the C program must
- explicitly use identifiers in the format expected by the Fortran
- 77 compiler. In order to do this, one simply wraps all C
- identifiers in one of the macros provided by `AC_F77_WRAPPERS'.
- For example, suppose you have the following Fortran 77 subroutine:
-
- subroutine foobar(x,y)
- double precision x, y
- y = 3.14159 * x
- return
- end
-
- You would then declare its prototype in C or C++ as:
-
- #define FOOBAR_F77 F77_FUNC(foobar,FOOBAR)
- #ifdef __cplusplus
- extern "C" /* prevent C++ name mangling */
- #endif
- void FOOBAR_F77(double *x, double *y);
-
- Note that we pass both the lowercase and uppercase versions of the
- function name to `F77_FUNC' so that it can select the right one.
- Note also that all parameters to Fortran 77 routines are passed as
- pointers (*note Mixing Fortran 77 With C and C++: (automake)Mixing
- Fortran 77 With C and C++.).
-
- Although Autoconf tries to be intelligent about detecting the
- name-mangling scheme of the Fortran 77 compiler, there may be
- Fortran 77 compilers that it doesn't support yet. In this case,
- the above code will generate a compile-time error, but some other
- behavior (e.g. disabling Fortran-related features) can be induced
- by checking whether the `F77_FUNC' macro is defined.
-
- Now, to call that routine from a C program, we would do something
- like:
-
- {
- double x = 2.7183, y;
- FOOBAR_F77(&x, &y);
- }
-
- If the Fortran 77 identifier contains an underscore (e.g.
- `foo_bar'), you should use `F77_FUNC_' instead of `F77_FUNC' (with
- the same arguments). This is because some Fortran 77 compilers
- mangle names differently if they contain an underscore.
-
- - Macro: AC_F77_FUNC (NAME, [SHELLVAR])
- Given an identifier NAME, set the shell variable SHELLVAR to hold
- the mangled version NAME according to the rules of the Fortran 77
- linker (see also `AC_F77_WRAPPERS'). SHELLVAR is optional; if it
- is not supplied, the shell variable will be simply NAME. The
- purpose of this macro is to give the caller a way to access the
- name-mangling information other than through the C preprocessor as
- above; for example, to call Fortran routines from some language
- other than C/C++.

-System Services
-===============
-
- The following macros check for operating system services or
-capabilities.
-
- - Macro: AC_PATH_X
- Try to locate the X Window System include files and libraries. If
- the user gave the command line options `--x-includes=DIR' and
- `--x-libraries=DIR', use those directories. If either or both
- were not given, get the missing values by running `xmkmf' on a
- trivial `Imakefile' and examining the `Makefile' that it produces.
- If that fails (such as if `xmkmf' is not present), look for them
- in several directories where they often reside. If either method
- is successful, set the shell variables `x_includes' and
- `x_libraries' to their locations, unless they are in directories
- the compiler searches by default.
-
- If both methods fail, or the user gave the command line option
- `--without-x', set the shell variable `no_x' to `yes'; otherwise
- set it to the empty string.
-
- - Macro: AC_PATH_XTRA
- An enhanced version of `AC_PATH_X'. It adds the C compiler flags
- that X needs to output variable `X_CFLAGS', and the X linker flags
- to `X_LIBS'. Define `X_DISPLAY_MISSING' if X is not available.
-
- This macro also checks for special libraries that some systems
- need in order to compile X programs. It adds any that the system
- needs to output variable `X_EXTRA_LIBS'. And it checks for
- special X11R6 libraries that need to be linked with before
- `-lX11', and adds any found to the output variable `X_PRE_LIBS'.
-
-
- - Macro: AC_SYS_INTERPRETER
- Check whether the system supports starting scripts with a line of
- the form `#! /bin/csh' to select the interpreter to use for the
- script. After running this macro, shell code in `configure.ac'
- can check the shell variable `interpval'; it will be set to `yes'
- if the system supports `#!', `no' if not.
-
- - Macro: AC_SYS_LARGEFILE
- Arrange for large-file support(1). On some hosts, one must use
- special compiler options to build programs that can access large
- files. Append any such options to the output variable `CC'.
- Define `_FILE_OFFSET_BITS' and `_LARGE_FILES' if necessary.
-
- Large-file support can be disabled by configuring with the
- `--disable-largefile' option.
-
- If you use this macro, check that your program works even when
- `off_t' is longer than `long', since this is common when
- large-file support is enabled. For example, it is not correct to
- print an arbitrary `off_t' value `X' with `printf ("%ld", (long)
- X)'.
-
- - Macro: AC_SYS_LONG_FILE_NAMES
- If the system supports file names longer than 14 characters, define
- `HAVE_LONG_FILE_NAMES'.
-
- - Macro: AC_SYS_POSIX_TERMIOS
- Check to see if POSIX termios headers and functions are available
- on the system. If so, set the shell variable
- `am_cv_sys_posix_termios' to `yes'. If not, set the variable to
- `no'.

-
- - Macro: AC_AIX
- If on AIX, define `_ALL_SOURCE'. Allows the use of some BSD

- If on a POSIXized ISC UNIX, define `_POSIX_SOURCE' and add
- `-posix' (for the GNU C compiler) or `-Xp' (for other C compilers)
- to output variable `CC'. This allows the use of POSIX facilities.
- Must be called after `AC_PROG_CC' and before any other macros
- that run the C compiler.
-
- - Macro: AC_MINIX
- If on Minix, define `_MINIX' and `_POSIX_SOURCE' and define

-Writing Tests
-*************
-
- If the existing feature tests don't do something you need, you have
-to write new ones. These macros are the building blocks. They provide
-ways for other macros to check whether various kinds of features are
-available and report the results.
-
- This chapter contains some suggestions and some of the reasons why
-the existing tests are written the way they are. You can also learn a
-lot about how to write Autoconf tests by looking at the existing ones.
-If something goes wrong in one or more of the Autoconf tests, this
-information can help you understand the assumptions behind them, which
-might help you figure out how to best solve the problem.
-
- These macros check the output of the C compiler system. They do not
-cache the results of their tests for future use (*note Caching
-Results::), because they don't know enough about the information they
-are checking for to generate a cache variable name. They also do not
-print any messages, for the same reason. The checks for particular
-kinds of C features call these macros and do cache their results and
-print messages about what they're checking for.
-
- When you write a feature test that could be applicable to more than
-one software package, the best thing to do is encapsulate it in a new
-macro. *Note Writing Autoconf Macros::, for how to do that.

-Examining Declarations
-======================
-
- The macro `AC_TRY_CPP' is used to check whether particular header
-files exist. You can check for one at a time, or more than one if you
-need several header files to all exist for some purpose.
-
- - Macro: AC_TRY_CPP (INCLUDES, [ACTION-IF-TRUE], [ACTION-IF-FALSE])
- INCLUDES is C or C++ `#include' statements and declarations, on
- which shell variable, back quote, and backslash substitutions are
- performed. (Actually, it can be any C program, but other
- statements are probably not useful.) If the preprocessor produces
- no error messages while processing it, run shell commands
- ACTION-IF-TRUE. Otherwise run shell commands ACTION-IF-FALSE.
-
- This macro uses `CPPFLAGS', but not `CFLAGS', because `-g', `-O',
- etc. are not valid options to many C preprocessors.
-
- Here is how to find out whether a header file contains a particular
-declaration, such as a typedef, a structure, a structure member, or a
-function. Use `AC_EGREP_HEADER' instead of running `grep' directly on
-the header file; on some systems the symbol might be defined in another
-header file that the file you are checking `#include's.
-
- - Macro: AC_EGREP_HEADER (PATTERN, HEADER-FILE, ACTION-IF-FOUND,
- [ACTION-IF-NOT-FOUND])
- If the output of running the preprocessor on the system header file
- HEADER-FILE matches the `egrep' regular expression PATTERN,
- execute shell commands ACTION-IF-FOUND, otherwise execute
- ACTION-IF-NOT-FOUND.
-
- To check for C preprocessor symbols, either defined by header files
-or predefined by the C preprocessor, use `AC_EGREP_CPP'. Here is an
-example of the latter:
-
- AC_EGREP_CPP(yes,
- [#ifdef _AIX
- yes
- #endif
- ], is_aix=yes, is_aix=no)
-
- - Macro: AC_EGREP_CPP (PATTERN, PROGRAM, [ACTION-IF-FOUND],
- [ACTION-IF-NOT-FOUND])
- PROGRAM is the text of a C or C++ program, on which shell
- variable, back quote, and backslash substitutions are performed.
- If the output of running the preprocessor on PROGRAM matches the
- `egrep' regular expression PATTERN, execute shell commands
- ACTION-IF-FOUND, otherwise execute ACTION-IF-NOT-FOUND.
-
- This macro calls `AC_PROG_CPP' or `AC_PROG_CXXCPP' (depending on
- which language is current, *note Language Choice::), if it hasn't
- been called already.

-
-Examining Syntax
-================
-
- To check for a syntax feature of the C, C++ or Fortran 77 compiler,
-such as whether it recognizes a certain keyword, use `AC_TRY_COMPILE' to
-try to compile a small program that uses that feature. You can also use
-it to check for structures and structure members that are not present on
-all systems.
-
- - Macro: AC_TRY_COMPILE (INCLUDES, FUNCTION-BODY, [ACTION-IF-FOUND],
- [ACTION-IF-NOT-FOUND])
- Create a C, C++ or Fortran 77 test program (depending on which
- language is current, *note Language Choice::), to see whether a
- function whose body consists of FUNCTION-BODY can be compiled.
-
- For C and C++, INCLUDES is any `#include' statements needed by the
- code in FUNCTION-BODY (INCLUDES will be ignored if the currently
- selected language is Fortran 77). This macro also uses `CFLAGS'
- or `CXXFLAGS' if either C or C++ is the currently selected
- language, as well as `CPPFLAGS', when compiling. If Fortran 77 is
- the currently selected language then `FFLAGS' will be used when
- compiling.
-
- If the file compiles successfully, run shell commands
- ACTION-IF-FOUND, otherwise run ACTION-IF-NOT-FOUND.
-
- This macro does not try to link; use `AC_TRY_LINK' if you need to
- do that (*note Examining Libraries::).
-
-
-File: autoconf.info, Node: Examining Libraries, Next: Run Time, Prev: Examining Syntax, Up: Writing Tests
-
-Examining Libraries
-===================
-
- To check for a library, a function, or a global variable, Autoconf
-`configure' scripts try to compile and link a small program that uses
-it. This is unlike Metaconfig, which by default uses `nm' or `ar' on
-the C library to try to figure out which functions are available.
-Trying to link with the function is usually a more reliable approach
-because it avoids dealing with the variations in the options and output
-formats of `nm' and `ar' and in the location of the standard libraries.
-It also allows configuring for cross-compilation or checking a
-function's runtime behavior if needed. On the other hand, it can be
-slower than scanning the libraries once.
-
- A few systems have linkers that do not return a failure exit status
-when there are unresolved functions in the link. This bug makes the
-configuration scripts produced by Autoconf unusable on those systems.
-However, some of them can be given options that make the exit status
-correct. This is a problem that Autoconf does not currently handle
-automatically. If users encounter this problem, they might be able to
-solve it by setting `LDFLAGS' in the environment to pass whatever
-options the linker needs (for example, `-Wl,-dn' on MIPS RISC/OS).
-
- `AC_TRY_LINK' is used to compile test programs to test for functions
-and global variables. It is also used by `AC_CHECK_LIB' to check for
-libraries (*note Libraries::), by adding the library being checked for
-to `LIBS' temporarily and trying to link a small program.
-
- - Macro: AC_TRY_LINK (INCLUDES, FUNCTION-BODY, [ACTION-IF-FOUND],
- [ACTION-IF-NOT-FOUND])
- Depending on the current language (*note Language Choice::),
- create a test program to see whether a function whose body
- consists of FUNCTION-BODY can be compiled and linked.
-
- For C and C++, INCLUDES is any `#include' statements needed by the
- code in FUNCTION-BODY (INCLUDES will be ignored if the currently
- selected language is Fortran 77). This macro also uses `CFLAGS'
- or `CXXFLAGS' if either C or C++ is the currently selected
- language, as well as `CPPFLAGS', when compiling. If Fortran 77 is
- the currently selected language then `FFLAGS' will be used when
- compiling. However, both `LDFLAGS' and `LIBS' will be used during
- linking in all cases.
-
- If the file compiles and links successfully, run shell commands
- ACTION-IF-FOUND, otherwise run ACTION-IF-NOT-FOUND.
-
- - Macro: AC_TRY_LINK_FUNC (FUNCTION, [ACTION-IF-FOUND],
- [ACTION-IF-NOT-FOUND])
- Depending on the current language (*note Language Choice::),
- create a test program to see whether a program whose body consists
- of a prototype of and a call to FUNCTION can be compiled and
- linked.
-
- If the file compiles and links successfully, run shell commands
- ACTION-IF-FOUND, otherwise run ACTION-IF-NOT-FOUND.

-Checking Run Time Behavior
-==========================
-
- Sometimes you need to find out how a system performs at run time,
-such as whether a given function has a certain capability or bug. If
-you can, make such checks when your program runs instead of when it is
-configured. You can check for things like the machine's endianness when
-your program initializes itself.
-
- If you really need to test for a run-time behavior while configuring,
-you can write a test program to determine the result, and compile and
-run it using `AC_TRY_RUN'. Avoid running test programs if possible,
-because this prevents people from configuring your package for
-cross-compiling.

-
-Running Test Programs
----------------------
-
- Use the following macro if you need to test run-time behavior of the
-system while configuring.
-
- - Macro: AC_TRY_RUN (PROGRAM, [ACTION-IF-TRUE], [ACTION-IF-FALSE],
- [ACTION-IF-CROSS-COMPILING])
- PROGRAM is the text of a C program, on which shell variable and
- back quote substitutions are performed. If it compiles and links
- successfully and returns an exit status of 0 when executed, run
- shell commands ACTION-IF-TRUE. Otherwise, run shell commands
- ACTION-IF-FALSE; the exit status of the program is available in
- the shell variable `$?'. This macro uses `CFLAGS' or `CXXFLAGS',
- `CPPFLAGS', `LDFLAGS', and `LIBS' when compiling.
-
- If the C compiler being used does not produce executables that run
- on the system where `configure' is being run, then the test
- program is not run. If the optional shell commands
- ACTION-IF-CROSS-COMPILING are given, they are run instead.
- Otherwise, `configure' prints an error message and exits.
-
- Try to provide a pessimistic default value to use when
-cross-compiling makes run-time tests impossible. You do this by
-passing the optional last argument to `AC_TRY_RUN'. `autoconf' prints
-a warning message when creating `configure' each time it encounters a
-call to `AC_TRY_RUN' with no ACTION-IF-CROSS-COMPILING argument given.
-You may ignore the warning, though users will not be able to configure
-your package for cross-compiling. A few of the macros distributed with
-Autoconf produce this warning message.
-
- To configure for cross-compiling you can also choose a value for
-those parameters based on the canonical system name (*note Manual
-Configuration::). Alternatively, set up a test results cache file with
-the correct values for the host system (*note Caching Results::).
-
- To provide a default for calls of `AC_TRY_RUN' that are embedded in
-other macros, including a few of the ones that come with Autoconf, you
-can call `AC_PROG_CC' before running them. Then, if the shell variable
-`cross_compiling' is set to `yes', use an alternate method to get the
-results instead of calling the macros.
-
-
-File: autoconf.info, Node: Guidelines, Next: Test Functions, Prev: Test Programs, Up: Run Time
-
-Guidelines for Test Programs
-----------------------------
-
- Test programs should not write anything to the standard output. They
-should return 0 if the test succeeds, nonzero otherwise, so that success
-can be distinguished easily from a core dump or other failure;
-segmentation violations and other failures produce a nonzero exit
-status. Test programs should `exit', not `return', from `main',
-because on some systems (old Suns, at least) the argument to `return'
-in `main' is ignored.
-
- Test programs can use `#if' or `#ifdef' to check the values of
-preprocessor macros defined by tests that have already run. For
-example, if you call `AC_HEADER_STDC', then later on in `configure.ac'
-you can have a test program that includes an ANSI C header file
-conditionally:
-
- #if STDC_HEADERS
- # include <stdlib.h>
- #endif
-
- If a test program needs to use or create a data file, give it a name
-that starts with `conftest', such as `conftest.data'. The `configure'
-script cleans up by running `rm -rf conftest*' after running test
-programs and if the script is interrupted.
-
-
-File: autoconf.info, Node: Test Functions, Prev: Guidelines, Up: Run Time
-
-Test Functions
---------------
-
- Function declarations in test programs should have a prototype
-conditionalized for C++. In practice, though, test programs rarely need
-functions that take arguments.
-
- #ifdef __cplusplus
- foo (int i)
- #else
- foo (i) int i;
- #endif
-
- Functions that test programs declare should also be conditionalized
-for C++, which requires `extern "C"' prototypes. Make sure to not
-include any header files containing clashing prototypes.
-
- #ifdef __cplusplus
- extern "C" void *malloc (size_t);
- #else
- char *malloc ();
- #endif
-
- If a test program calls a function with invalid parameters (just to
-see whether it exists), organize the program to ensure that it never
-invokes that function. You can do this by calling it in another
-function that is never invoked. You can't do it by putting it after a
-call to `exit', because GCC version 2 knows that `exit' never returns
-and optimizes out any code that follows it in the same block.
-
- If you include any header files, make sure to call the functions
-relevant to them with the correct number of arguments, even if they are
-just 0, to avoid compilation errors due to prototypes. GCC version 2
-has internal prototypes for several functions that it automatically
-inlines; for example, `memcpy'. To avoid errors when checking for
-them, either pass them the correct number of arguments or redeclare them
-with a different return type (such as `char').

-Multiple Cases
-==============
-
- Some operations are accomplished in several possible ways, depending

-statement". Autoconf does not directly provide one; however, it is
-easy to simulate by using a shell variable to keep track of whether a
-way to perform the operation has been found yet.
-
- Here is an example that uses the shell variable `fstype' to keep

-
-Language Choice
-===============
-
- Autoconf-generated `configure' scripts check for the C compiler and
-its features by default. Packages that use other programming languages
-(maybe more than one, e.g. C and C++) need to test features of the
-compilers for the respective languages. The following macros determine
-which programming language is used in the subsequent tests in
-`configure.ac'.
-
- - Macro: AC_LANG (LANGUAGE)
- Do compilation tests using the compiler, preprocessor and file
- extensions for the specified LANGUAGE.
-
- Supported languages are:
-
- `C'
- Do compilation tests using `CC' and `CPP' and use extension
- `.c' for test programs.
-
- `C++'
- Do compilation tests using `CXX' and `CXXCPP' and use
- extension `.C' for test programs.
-
- `Fortran 77'
- Do compilation tests using `F77' and use extension `.f' for
- test programs.
-
- - Macro: AC_LANG_PUSH (LANGUAGE)
- Remember the current language (as set by `AC_LANG') on a stack, and
- then select the LANGUAGE. Use this macro and `AC_LANG_POP' in
- macros that need to temporarily switch to a particular language.
-
- - Macro: AC_LANG_POP ([LANGUAGE])
- Select the language that is saved on the top of the stack, as set
- by `AC_LANG_PUSH', and remove it from the stack.
-
- If given, LANGUAGE specifies the language we just _quit_. It is a
- good idea to specify it when it's known (which should be the
- case...), since Autoconf will detect inconsistencies.
-
- AC_LANG_PUSH(Fortran 77)
- # Perform some tests on Fortran 77.
- # ...
- AC_LANG_POP(Fortran 77)
-
- - Macro: AC_REQUIRE_CPP
- Ensure that whichever preprocessor would currently be used for
- tests has been found. Calls `AC_REQUIRE' (*note Prerequisite
- Macros::) with an argument of either `AC_PROG_CPP' or
- `AC_PROG_CXXCPP', depending on which language is current.

-
-Results of Tests
-****************
-
- Once `configure' has determined whether a feature exists, what can
-it do to record that information? There are four sorts of things it can
-do: define a C preprocessor symbol, set a variable in the output files,
-save the result in a cache file for future `configure' runs, and print
-a message letting the user know the result of the test.
-

-* Printing Messages:: Notifying `configure' users
-
-
-File: autoconf.info, Node: Defining Symbols, Next: Setting Output Variables, Prev: Results, Up: Results
-
-Defining C Preprocessor Symbols
-===============================
-
- A common action to take in response to a feature test is to define a
-C preprocessor symbol indicating the results of the test. That is done
-by calling `AC_DEFINE' or `AC_DEFINE_UNQUOTED'.
-
- By default, `AC_OUTPUT' places the symbols defined by these macros
-into the output variable `DEFS', which contains an option
-`-DSYMBOL=VALUE' for each symbol defined. Unlike in Autoconf version
-1, there is no variable `DEFS' defined while `configure' is running.
-To check whether Autoconf macros have already defined a certain C
-preprocessor symbol, test the value of the appropriate cache variable,
-as in this example:
-
- AC_CHECK_FUNC(vprintf, [AC_DEFINE(HAVE_VPRINTF)])
- if test "$ac_cv_func_vprintf" != yes; then
- AC_CHECK_FUNC(_doprnt, [AC_DEFINE(HAVE_DOPRNT)])
- fi
-
- If `AC_CONFIG_HEADERS' has been called, then instead of creating
-`DEFS', `AC_OUTPUT' creates a header file by substituting the correct
-values into `#define' statements in a template file. *Note
-Configuration Headers::, for more information about this kind of output.
-
- - Macro: AC_DEFINE (VARIABLE, [VALUE], [DESCRIPTION])
- Define C preprocessor variable VARIABLE. If VALUE is given, set
- VARIABLE to that value (verbatim), otherwise set it to 1. VALUE
- should not contain literal newlines, and if you are not using
- `AC_CONFIG_HEADERS' it should not contain any `#' characters, as
- `make' tends to eat them. To use a shell variable (which you need
- to do in order to define a value containing the M4 quote
- characters `[' or `]'), use `AC_DEFINE_UNQUOTED' instead.
- DESCRIPTION is only useful if you are using `AC_CONFIG_HEADERS'.
- In this case, DESCRIPTION is put into the generated `config.h.in'
- as the comment before the macro define. The following example
- defines the C preprocessor variable `EQUATION' to be the string
- constant `"$a > $b"':
-
- AC_DEFINE(EQUATION, "$a > $b")
-
- - Macro: AC_DEFINE_UNQUOTED (VARIABLE, [VALUE], [DESCRIPTION])
- Like `AC_DEFINE', but three shell expansions are
- performed--once--on VARIABLE and VALUE: variable expansion (`$'),
- command substitution (``'), and backslash escaping (`\'). Single
- and double quote characters in the value have no special meaning.
- Use this macro instead of `AC_DEFINE' when VARIABLE or VALUE is a
- shell variable. Examples:
-
- AC_DEFINE_UNQUOTED(config_machfile, "$machfile")
- AC_DEFINE_UNQUOTED(GETGROUPS_T, $ac_cv_type_getgroups)
- AC_DEFINE_UNQUOTED($ac_tr_hdr)
-
- Due to the syntactical bizarreness of the Bourne shell, do not use
-semicolons to separate `AC_DEFINE' or `AC_DEFINE_UNQUOTED' calls from
-other macro calls or shell code; that can cause syntax errors in the
-resulting `configure' script. Use either spaces or newlines. That is,
-do this:
-
- AC_CHECK_HEADER(elf.h, [AC_DEFINE(SVR4) LIBS="$LIBS -lelf"])
-
-or this:
-
- AC_CHECK_HEADER(elf.h,
- [AC_DEFINE(SVR4)
- LIBS="$LIBS -lelf"])
-
-instead of this:
-
- AC_CHECK_HEADER(elf.h, [AC_DEFINE(SVR4); LIBS="$LIBS -lelf"])

-Setting Output Variables
-========================
-
- Another way to record the results of tests is to set "output
-variables", which are shell variables whose values are substituted into
-files that `configure' outputs. The two macros below create new output
-variables. *Note Preset Output Variables::, for a list of output
-variables that are always available.
-
- - Macro: AC_SUBST (VARIABLE, [VALUE])
- Create an output variable from a shell variable. Make `AC_OUTPUT'
- substitute the variable VARIABLE into output files (typically one
- or more `Makefile's). This means that `AC_OUTPUT' will replace
- instances of `@VARIABLE@' in input files with the value that the
- shell variable VARIABLE has when `AC_OUTPUT' is called. This
- value of VARIABLE should not contain literal newlines.
-
- If VALUE is given, in addition assign it to `variable'.
-
- - Macro: AC_SUBST_FILE (VARIABLE)
- Another way to create an output variable from a shell variable.
- Make `AC_OUTPUT' insert (without substitutions) the contents of
- the file named by shell variable VARIABLE into output files. This
- means that `AC_OUTPUT' will replace instances of `@VARIABLE@' in
- output files (such as `Makefile.in') with the contents of the file
- that the shell variable VARIABLE names when `AC_OUTPUT' is called.
- Set the variable to `/dev/null' for cases that do not have a file
- to insert.
-
- This macro is useful for inserting `Makefile' fragments containing
- special dependencies or other `make' directives for particular host
- or target types into `Makefile's. For example, `configure.ac'
- could contain:
-
- AC_SUBST_FILE(host_frag)
- host_frag=$srcdir/conf/sun4.mh
-
- and then a `Makefile.in' could contain:
-
- @host_frag@
-
- Running `configure' in different environments can be extremely
-dangerous. If for instance the user runs `CC=bizarre-cc ./configure',
-then the cache, `config.h' and many other output files will depend upon
-`bizarre-cc' being the C compiler. If for some reason the user runs
-`/configure' again, or if it is run via `./config.status --recheck',
-(*Note Automatic Remaking::, and *note config.status Invocation::),
-then the configuration can be inconsistent, composed of results
-depending upon two different compilers.
-
- Such variables are named "precious variables", and can be declared
-as such by `AC_ARG_VAR'.
-
- - Macro: AC_ARG_VAR (VARIABLE, DESCRIPTION)
- Declare VARIABLE is a precious variable, and include its
- DESCRIPTION in the variable section of `./configure --help'.
-
- Being precious means that
- - VARIABLE is `AC_SUBST''d.
-
- - VARIABLE is kept in the cache including if it was not
- specified on the `./configure' command line. Indeed, while
- `configure' can notice the definition of `CC' in `./configure
- CC=bizarre-cc', it is impossible to notice it in
- `CC=bizarre-cc ./configure', which, unfortunately, is what
- most users do.
-
- - VARIABLE is checked for consistency between two `configure'
- runs. For instance:
-
- $ ./configure --silent --config-cache
- $ CC=cc ./configure --silent --config-cache
- configure: error: `CC' was not set in the previous run
- configure: error: changes in the environment can compromise \
- the build
- configure: error: run `make distclean' and/or \
- `rm config.cache' and start over
-
- and similarly if the variable is unset, or if its content is
- changed.
-
- - VARIABLE is kept during automatic reconfiguration (*note
- config.status Invocation::) as if it had been passed as a
- command line argument, including when no cache is used:
-
- $ CC=/usr/bin/cc ./configure undeclared_var=raboof --silent
- $ ./config.status --recheck
- running /bin/sh ./configure undeclared_var=raboof --silent \
- CC=/usr/bin/cc --no-create --no-recursion

-Caching Results
-===============
-
- To avoid checking for the same features repeatedly in various
-`configure' scripts (or in repeated runs of one script), `configure'
-can optionally save the results of many checks in a "cache file" (*note
-Cache Files::). If a `configure' script runs with caching enabled and
-finds a cache file, it reads the results of previous runs from the
-cache and avoids rerunning those checks. As a result, `configure' can
-then run much faster than if it had to perform all of the checks every
-time.
-
- - Macro: AC_CACHE_VAL (CACHE-ID, COMMANDS-TO-SET-IT)
- Ensure that the results of the check identified by CACHE-ID are
- available. If the results of the check were in the cache file
- that was read, and `configure' was not given the `--quiet' or
- `--silent' option, print a message saying that the result was
- cached; otherwise, run the shell commands COMMANDS-TO-SET-IT. If
- the shell commands are run to determine the value, the value will
- be saved in the cache file just before `configure' creates its
- output files. *Note Cache Variable Names::, for how to choose the
- name of the CACHE-ID variable.
-
- The COMMANDS-TO-SET-IT _must have no side effects_ except for
- setting the variable CACHE-ID, see below.
-
- - Macro: AC_CACHE_CHECK (MESSAGE, CACHE-ID, COMMANDS-TO-SET-IT)
- A wrapper for `AC_CACHE_VAL' that takes care of printing the
- messages. This macro provides a convenient shorthand for the most
- common way to use these macros. It calls `AC_MSG_CHECKING' for
- MESSAGE, then `AC_CACHE_VAL' with the CACHE-ID and COMMANDS
- arguments, and `AC_MSG_RESULT' with CACHE-ID.
-
- The COMMANDS-TO-SET-IT _must have no side effects_ except for
- setting the variable CACHE-ID, see below.
-
- It is very common to find buggy macros using `AC_CACHE_VAL' or
-`AC_CACHE_CHECK', because people are tempted to call `AC_DEFINE' in the
-COMMANDS-TO-SET-IT. Instead, the code that _follows_ the call to
-`AC_CACHE_VAL' should call `AC_DEFINE', by examining the value of the
-cache variable. For instance, the following macro is broken:
-
- AC_DEFUN([AC_SHELL_TRUE],
- [AC_CACHE_CHECK([whether true(1) works], [ac_cv_shell_true_works],
- [ac_cv_shell_true_works=no
- true && ac_cv_shell_true_works=yes
- if test $ac_cv_shell_true_works = yes; then
- AC_DEFINE([TRUE_WORKS], 1
- [Define if `true(1)' works properly.])
- fi])
- ])
-
-This fails if the cache is enabled: the second time this macro is run,
-`TRUE_WORKS' _will not be defined_. The proper implementation is:
-
- AC_DEFUN([AC_SHELL_TRUE],
- [AC_CACHE_CHECK([whether true(1) works], [ac_cv_shell_true_works],
- [ac_cv_shell_true_works=no
- true && ac_cv_shell_true_works=yes])
- if test $ac_cv_shell_true_works = yes; then
- AC_DEFINE([TRUE_WORKS], 1
- [Define if `true(1)' works properly.])
- fi
- ])
-
- Also, COMMANDS-TO-SET-IT should not print any messages, for example
-with `AC_MSG_CHECKING'; do that before calling `AC_CACHE_VAL', so the
-messages are printed regardless of whether the results of the check are
-retrieved from the cache or determined by running the shell commands.

-Cache Variable Names
---------------------
-
- The names of cache variables should have the following format:
-
- PACKAGE-PREFIX_cv_VALUE-TYPE_SPECIFIC-VALUE_[ADDITIONAL-OPTIONS]
-
-for example, `ac_cv_header_stat_broken' or
-`ac_cv_prog_gcc_traditional'. The parts of the variable name are:
-
-PACKAGE-PREFIX
- An abbreviation for your package or organization; the same prefix
- you begin local Autoconf macros with, except lowercase by
- convention. For cache values used by the distributed Autoconf
- macros, this value is `ac'.
-
-`_cv_'
- Indicates that this shell variable is a cache value. This string
- _must_ be present in the variable name, including the leading
- underscore.
-
-VALUE-TYPE
- A convention for classifying cache values, to produce a rational
- naming system. The values used in Autoconf are listed in *Note
- Macro Names::.
-
-SPECIFIC-VALUE
- Which member of the class of cache values this test applies to.
- For example, which function (`alloca'), program (`gcc'), or output
- variable (`INSTALL').
-
-ADDITIONAL-OPTIONS
- Any particular behavior of the specific member that this test
- applies to. For example, `broken' or `set'. This part of the
- name may be omitted if it does not apply.
-
- The values assigned to cache variables may not contain newlines.
-Usually, their values will be boolean (`yes' or `no') or the names of
-files or functions; so this is not an important restriction.
-
-
-File: autoconf.info, Node: Cache Files, Next: Cache Checkpointing, Prev: Cache Variable Names, Up: Caching Results
-
-Cache Files
------------
-
- A cache file is a shell script that caches the results of configure
-tests run on one system so they can be shared between configure scripts
-and configure runs. It is not useful on other systems. If its contents
-are invalid for some reason, the user may delete or edit it.
-
- By default, `configure' uses no cache file (technically, it uses
-`--cache-file=/dev/null'), to avoid problems caused by accidental use
-of stale cache files.
-
- To enable caching, `configure' accepts `--config-cache' (or `-C') to
-cache results in the file `config.cache'. Alternatively,
-`--cache-file=FILE' specifies that FILE be the cache file. The cache
-file is created if it does not exist already. When `configure' calls
-`configure' scripts in subdirectories, it uses the `--cache-file'
-argument so that they share the same cache. *Note Subdirectories::,
-for information on configuring subdirectories with the
-`AC_CONFIG_SUBDIRS' macro.
-
- `config.status' only pays attention to the cache file if it is given
-the `--recheck' option, which makes it rerun `configure'.
-
- It is wrong to try to distribute cache files for particular system
-types. There is too much room for error in doing that, and too much
-administrative overhead in maintaining them. For any features that
-can't be guessed automatically, use the standard method of the canonical
-system type and linking files (*note Manual Configuration::).
-
- The site initialization script can specify a site-wide cache file to
-use, instead of the usual per-program cache. In this case, the cache
-file will gradually accumulate information whenever someone runs a new
-`configure' script. (Running `configure' merges the new cache results
-with the existing cache file.) This may cause problems, however, if
-the system configuration (e.g. the installed libraries or compilers)
-changes and the stale cache file is not deleted.
-
-
-File: autoconf.info, Node: Cache Checkpointing, Prev: Cache Files, Up: Caching Results
-
-Cache Checkpointing
--------------------
-
- If your configure script, or a macro called from configure.ac,
-happens to abort the configure process, it may be useful to checkpoint
-the cache a few times at key points using `AC_CACHE_SAVE'. Doing so
-will reduce the amount of time it takes to re-run the configure script
-with (hopefully) the error that caused the previous abort corrected.
-
- - Macro: AC_CACHE_LOAD
- Loads values from existing cache file, or creates a new cache file
- if a cache file is not found. Called automatically from `AC_INIT'.
-
- - Macro: AC_CACHE_SAVE
- Flushes all cached values to the cache file. Called automatically
- from `AC_OUTPUT', but it can be quite useful to call
- `AC_CACHE_SAVE' at key points in configure.ac.
-
- For instance:
-
- ... AC_INIT, etc. ...
- # Checks for programs.
- AC_PROG_CC
- AC_PROG_GCC_TRADITIONAL
- ... more program checks ...
- AC_CACHE_SAVE
-
- # Checks for libraries.
- AC_CHECK_LIB(nsl, gethostbyname)
- AC_CHECK_LIB(socket, connect)
- ... more lib checks ...
- AC_CACHE_SAVE
-
- # Might abort...
- AM_PATH_GTK(1.0.2,, (exit 1); exit)
- AM_PATH_GTKMM(0.9.5,, (exit 1); exit)
- ... AC_OUTPUT, etc. ...

-Printing Messages
-=================
-
- `configure' scripts need to give users running them several kinds of
-information. The following macros print messages in ways appropriate
-for each kind. The arguments to all of them get enclosed in shell
-double quotes, so the shell performs variable and back-quote
-substitution on them.
-
- These macros are all wrappers around the `echo' shell command.
-`configure' scripts should rarely need to run `echo' directly to print
-messages for the user. Using these macros makes it easy to change how
-and when each kind of message is printed; such changes need only be
-made to the macro definitions and all of the callers will change
-automatically.
-
- To diagnose static issues, i.e., when `autoconf' is run, see *Note
-Reporting Messages::.
-
- - Macro: AC_MSG_CHECKING (FEATURE-DESCRIPTION)
- Notify the user that `configure' is checking for a particular
- feature. This macro prints a message that starts with `checking '
- and ends with `...' and no newline. It must be followed by a call
- to `AC_MSG_RESULT' to print the result of the check and the
- newline. The FEATURE-DESCRIPTION should be something like
- `whether the Fortran compiler accepts C++ comments' or `for c89'.
-
- This macro prints nothing if `configure' is run with the `--quiet'
- or `--silent' option.
-
- - Macro: AC_MSG_RESULT (RESULT-DESCRIPTION)
- Notify the user of the results of a check. RESULT-DESCRIPTION is
- almost always the value of the cache variable for the check,
- typically `yes', `no', or a file name. This macro should follow a
- call to `AC_MSG_CHECKING', and the RESULT-DESCRIPTION should be
- the completion of the message printed by the call to
- `AC_MSG_CHECKING'.
-
- This macro prints nothing if `configure' is run with the `--quiet'
- or `--silent' option.
-
- - Macro: AC_MSG_NOTICE (MESSAGE)
- Deliver the MESSAGE to the user. It is useful mainly to print a
- general description of the overall purpose of a group of feature
- checks, e.g.,
-
- AC_MSG_NOTICE([checking if stack overflow is detectable])
-
- This macro prints nothing if `configure' is run with the `--quiet'
- or `--silent' option.
-
- - Macro: AC_MSG_ERROR (ERROR-DESCRIPTION, [EXIT-STATUS])
- Notify the user of an error that prevents `configure' from
- completing. This macro prints an error message to the standard
- error output and exits `configure' with EXIT-STATUS (1 by default).
- ERROR-DESCRIPTION should be something like `invalid value $HOME
- for \$HOME'.
-
- The ERROR-DESCRIPTION should start with a lower-case letter, and
- "cannot" is preferred to "can't".
-
- - Macro: AC_MSG_WARN (PROBLEM-DESCRIPTION)
- Notify the `configure' user of a possible problem. This macro
- prints the message to the standard error output; `configure'
- continues running afterward, so macros that call `AC_MSG_WARN'
- should provide a default (back-up) behavior for the situations
- they warn about. PROBLEM-DESCRIPTION should be something like `ln
- -s seems to make hard links'.

-Programming in M4
-*****************
-
- Autoconf is written on top of two layers: "M4sugar", which provides
-convenient macros for pure M4 programming, and "M4sh", which provides
-macros dedicated to shell script generation.
-
- As of this version of Autoconf, these two layers are still
-experimental, and their interface might change in the future. As a
-matter of fact, _anything that is not documented must not be used_.

-============
-
- The most common brokenness of existing macros is an improper

-
-Active Characters
------------------
-
- To fully understand where proper quotation is important, you first
-need to know what are the special characters in Autoconf: `#' introduces
-a comment inside which no macro expansion is performed, `,' separates
-arguments, `[' and `]' are the quotes themselves, and finally `(' and
-`)' (which `m4' tries to match by pairs).
-
- In order to understand the delicate case of macro calls, we first
-have to present some obvious failures. Below they are "obvious-ified",
-although you find them in real life, they are usually in disguise.
-
- Comments, introduced by a hash and running up to the newline, are
-opaque tokens to the top level: active characters are turned off, and
-there is no macro expansion:
-
- # define([def], ine)
- =># define([def], ine)
-
- Each time there can be a macro expansion, there is a quotation
-expansion; i.e., one level of quotes is stripped:
-
- int tab[10];
- =>int tab10;
- [int tab[10];]
- =>int tab[10];
-
- Without this in mind, the reader will try hopelessly to use her macro
-`array':
-
- define([array], [int tab[10];])
- array
- =>int tab10;
- [array]
- =>array
-
-How can you correctly output the intended results(1)?

-File: autoconf.info, Node: One Macro Call, Next: Quotation and Nested Macros, Prev: Active Characters, Up: M4 Quotation
-
-One Macro Call
---------------
-
- Let's proceed on the interaction between active characters and macros
-with this small macro, which just returns its first argument:
-
- define([car], [$1])
-
-The two pairs of quotes above are not part of the arguments of
-`define'; rather, they are understood by the top level when it tries to
-find the arguments of `define'. Therefore, it is equivalent to write:
-
- define(car, $1)
-
-But, while it is acceptable for a `configure.ac' to avoid unneeded
-quotes, it is bad practice for Autoconf macros which must both be more
-robust and also advocate perfect style.
-
- At the top level, there are only two possible quotings: either you
-quote or you don't:
-
- car(foo, bar, baz)
- =>foo
- [car(foo, bar, baz)]
- =>car(foo, bar, baz)
-
- Let's pay attention to the special characters:
-
- car(#)
- error-->EOF in argument list
-
- The closing parenthesis is hidden in the comment; with a hypothetical
-quoting, the top level understood it this way:
-
- car([#)]
-
-Proper quotation, of course, fixes the problem:
-
- car([#])
- =>#
-
- The reader will easily understand the following examples:
-
- car(foo, bar)
- =>foo
- car([foo, bar])
- =>foo, bar
- car((foo, bar))
- =>(foo, bar)
- car([(foo], [bar)])
- =>(foo
- car([], [])
- =>
- car([[]], [[]])
- =>[]
-
- With this in mind, we can explore the cases where macros invoke
-macros...
-
-
-File: autoconf.info, Node: Quotation and Nested Macros, Next: Quadrigraphs, Prev: One Macro Call, Up: M4 Quotation
-
-Quotation and Nested Macros
----------------------------
-
- The examples below use the following macros:
-
- define([car], [$1])
- define([active], [ACT, IVE])
- define([array], [int tab[10]])
-
- Each additional embedded macro call introduces other possible
-interesting quotations:
-
- car(active)
- =>ACT
- car([active])
- =>ACT, IVE
- car([[active]])
- =>active
-
- In the first case, the top level looks for the arguments of `car',
-and finds `active'. Because `m4' evaluates its arguments before
-applying the macro, `active' is expanded, which results in:
-
- car(ACT, IVE)
- =>ACT
-
-In the second case, the top level gives `active' as first and only
-argument of `car', which results in:
-
- active
- =>ACT, IVE
-
-i.e., the argument is evaluated _after_ the macro that invokes it. In
-the third case, `car' receives `[active]', which results in:
-
- [active]
- =>active
-
-exactly as we already saw above.
-
- The example above, applied to a more realistic example, gives:
-
- car(int tab[10];)
- =>int tab10;
- car([int tab[10];])
- =>int tab10;
- car([[int tab[10];]])
- =>int tab[10];
-
-Huh? The first case is easily understood, but why is the second wrong,
-and the third right? To understand that, you must know that after `m4'
-expands a macro, the resulting text is immediately subjected to macro
-expansion and quote removal. This means that the quote removal occurs
-twice--first before the argument is passed to the `car' macro, and
-second after the `car' macro expands to the first argument.
-
- As the author of the Autoconf macro `car', you then consider it to
-be incorrect that your users have to double-quote the arguments of
-`car', so you "fix" your macro. Let's call it `qar' for quoted car:
-
- define([qar], [[$1]])
-
-and check that `qar' is properly fixed:
-
- qar([int tab[10];])
- =>int tab[10];
-
-Ahhh! That's much better.
-
- But note what you've done: now that the arguments are literal
-strings, if the user wants to use the results of expansions as
-arguments, she has to use an _unquoted_ macro call:
-
- qar(active)
- =>ACT
-
-where she wanted to reproduce what she used to do with `car':
-
- car([active])
- =>ACT, IVE
-
-Worse yet: she wants to use a macro that produces a set of `cpp' macros:
-
- define([my_includes], [#include <stdio.h>])
- car([my_includes])
- =>#include <stdio.h>
- qar(my_includes)
- error-->EOF in argument list
-
- This macro, `qar', because it double quotes its arguments, forces
-its users to leave their macro calls unquoted, which is dangerous.
-Commas and other active symbols are interpreted by `m4' before they are
-given to the macro, often not in the way the users expect. Also,
-because `qar' behaves differently from the other macros, it's an
-exception that should be avoided in Autoconf.
-

-
-Quadrigraphs
-------------
-
- When writing an autoconf macro you may occasionally need to generate
-special characters that are difficult to express with the standard
-autoconf quoting rules. For example, you may need to output the regular
-expression `[^[]', which matches any character other than `['. This
-expression contains unbalanced brackets so it cannot be put easily into
-an M4 macro.
-
- You can work around this problem by using one of the following
-"quadrigraphs":
-
-`@<:@'
- `['
-
-`@:>@'
- `]'
-
-`@S|@'
- `$'
-
-`@%:@'
- `#'
-
- Quadrigraphs are replaced at a late stage of the translation process,
-after `m4' is run, so they do not get in the way of M4 quoting. For
-example, the string `[^@<:@]', if properly quoted, will appear as
-`[^[]' in the `configure' script.
-
-
-File: autoconf.info, Node: Quotation Rule Of Thumb, Prev: Quadrigraphs, Up: M4 Quotation
-
-Quotation Rule Of Thumb
------------------------
-
- To conclude, the quotation rule of thumb is:
-
- _One pair of quotes per pair of parentheses._
-
- Never over-quote, never under-quote, in particular in the definition
-of macros. In the few places where the macros need to use brackets
-(usually in C program text or regular expressions), properly quote _the
-arguments_!
-
- It is common to read Autoconf programs with snippets like:
-
- AC_TRY_LINK(
- changequote(<<, >>)dnl
- <<#include <time.h>
- #ifndef tzname /* For SGI. */
- extern char *tzname[]; /* RS6000 and others reject char **tzname. */
- #endif>>,
- changequote([, ])dnl
- [atoi (*tzname);], ac_cv_var_tzname=yes, ac_cv_var_tzname=no)
-
-which is incredibly useless since `AC_TRY_LINK' is _already_ double
-quoting, so you just need:
-
- AC_TRY_LINK(
- [#include <time.h>
- #ifndef tzname /* For SGI. */
- extern char *tzname[]; /* RS6000 and others reject char **tzname. */
- #endif],
- [atoi (*tzname);],
- [ac_cv_var_tzname=yes],
- [ac_cv_var_tzname=no])
-
-The M4-fluent reader will note that these two examples are rigorously
-equivalent, since `m4' swallows both the `changequote(<<, >>)' and `<<'
-`>>' when it "collects" the arguments: these quotes are not part of the
-arguments!
-
- Simplified, the example above is just doing this:
-
- changequote(<<, >>)dnl
- <<[]>>
- changequote([, ])dnl
-
-instead of simply:
-
- [[]]
-
- With macros that do not double quote their arguments (which is the
-rule), double-quote the (risky) literals:
-
- AC_LINK_IFELSE([AC_LANG_PROGRAM(
- [[#include <time.h>
- #ifndef tzname /* For SGI. */
- extern char *tzname[]; /* RS6000 and others reject char **tzname. */
- #endif]],
- [atoi (*tzname);])],
- [ac_cv_var_tzname=yes],
- [ac_cv_var_tzname=no])
-
- See *Note Quadrigraphs::, for what to do if you run into a hopeless
-case where quoting does not suffice.
-
- When you create a `configure' script using newly written macros,
-examine it carefully to check whether you need to add more quotes in
-your macros. If one or more words have disappeared in the `m4' output,
-you need more quotes. When in doubt, quote.
-
- However, it's also possible to put on too many layers of quotes. If
-this happens, the resulting `configure' script will contain unexpanded
-macros. The `autoconf' program checks for this problem by doing `grep
-AC_ configure'.

-======================
-
- M4 by itself provides only a small, but sufficient, set of
-all-purpose macros. M4sugar introduces additional generic macros. Its
-name was coined by Lars J. Aas: "Readability And Greater Understanding
-Stands 4 M4sugar".

-
-Redefined M4 Macros
--------------------
-
- All the M4 native macros are moved in the `m4_' pseudo-namespace,
-e.g., M4sugar renames `define' as `m4_define' etc. There is one
-exception: `dnl' kept its original name, and no `m4_dnl' is defined.
-
- M4sugar redefines some M4 macros, and made them slightly incompatible
-with their native equivalent.
-
- - Macro: m4_defn (MACRO)
- Contrary to the M4 builtin, this macro fails if MACRO is not
- defined. See `m4_undefine'.
-
- - Macro: m4_undefine (MACRO)
- Contrary to the M4 builtin, this macro fails if MACRO is not
- defined. Use
-
- m4_ifdef([MACRO], [m4_undefine([MACRO])])
-
- to recover the behavior of the builtin.
-
- - Macro: m4_popdef (MACRO)
- Contrary to the M4 builtin, this macro fails if MACRO is not
- defined. See `m4_undefine'.

-
-Forbidden Patterns
-------------------
-
- M4sugar provides a means to define suspicious patterns, patterns
-describing tokens which should not be found in the output. For
-instance, if an Autoconf `configure' script includes tokens such as
-`AC_DEFINE', or `dnl', then most probably something went wrong
-(typically a macro was not evaluated because of over quotation).
-
- M4sugar forbids all the tokens matching `^m4_' and `^dnl$'.
-
- - Macro: m4_pattern_forbid (PATTERN)
- Declare no token matching PATTERN must be found in the output.
- Comments are not checked; this can be a problem if, for instance,
- you have some macro left unexpanded after an `#include'. No
- consensus is currently found in the Autoconf community, as some
- people consider it should be valid to name macros in comments
- (which doesn't makes sense to the author of this documentation, as
- `#'-comments should document the output, not the input, documented
- vy `dnl'-comments).
-
- Of course, you might encounter exceptions to these generic rules, for
-instance you might have to refer to `$m4_flags'.
-
- - Macro: m4_pattern_allow (PATTERN)
- Any token matching PATTERN is allowed, including if it matches an
- `m4_pattern_forbid' pattern.

-Writing Autoconf Macros
-***********************
-
- When you write a feature test that could be applicable to more than
-one software package, the best thing to do is encapsulate it in a new
-macro. Here are some instructions and guidelines for writing Autoconf
-macros.

-
-Macro Definitions
-=================
-
- Autoconf macros are defined using the `AC_DEFUN' macro, which is
-similar to the M4 builtin `define' macro. In addition to defining a
-macro, `AC_DEFUN' adds to it some code that is used to constrain the
-order in which macros are called (*note Prerequisite Macros::).
-
- An Autoconf macro definition looks like this:
-
- AC_DEFUN(MACRO-NAME, MACRO-BODY)
-
- You can refer to any arguments passed to the macro as `$1', `$2',
-etc. *Note How to define new macros: (m4.info)Definitions, for more
-complete information on writing M4 macros.
-
- Be sure to properly quote both the MACRO-BODY _and_ the MACRO-NAME
-to avoid any problems if the macro happens to have been previously
-defined.
-
- Each macro should have a header comment that gives its prototype,
-and a brief description. When arguments have default values, display
-them in the prototype. For example:
-
- # AC_MSG_ERROR(ERROR, [EXIT-STATUS = 1])
- # --------------------------------------
- define([AC_MSG_ERROR],
- [{ _AC_ECHO([configure: error: $1], 2); exit m4_default([$2], 1); }])
-
- Comments about the macro should be left in the header comment. Most
-other comments will make their way into `configure', so just keep using
-`#' to introduce comments.
-
- If you have some very special comments about pure M4 code, comments
-that make no sense in `configure' and in the header comment, then use
-the builtin `dnl': it causes `m4' to discard the text through the next
-newline.
-
- Keep in mind that `dnl' is rarely needed to introduce comments;
-`dnl' is more useful to get rid of the newlines following macros that
-produce no output, such as `AC_REQUIRE'.
-

-
-Macro Names
-===========
-
- All of the Autoconf macros have all-uppercase names starting with
-`AC_' to prevent them from accidentally conflicting with other text.
-All shell variables that they use for internal purposes have
-mostly-lowercase names starting with `ac_'. To ensure that your macros
-don't conflict with present or future Autoconf macros, you should
-prefix your own macro names and any shell variables they use with some
-other sequence. Possibilities include your initials, or an abbreviation
-for the name of your organization or software package.
-
- Most of the Autoconf macros' names follow a structured naming
-convention that indicates the kind of feature check by the name. The
-macro names consist of several words, separated by underscores, going
-from most general to most specific. The names of their cache variables
-use the same convention (*note Cache Variable Names::, for more
-information on them).
-
- The first word of the name after `AC_' usually tells the category of
-feature being tested. Here are the categories used in Autoconf for
-specific test macros, the kind of macro that you are more likely to
-write. They are also used for cache variables, in all-lowercase. Use
-them where applicable; where they're not, invent your own categories.
-
-`C'
- C language builtin features.
-
-`DECL'
- Declarations of C variables in header files.
-
-`FUNC'
- Functions in libraries.
-
-`GROUP'
- UNIX group owners of files.
-
-`HEADER'
- Header files.
-
-`LIB'
- C libraries.
-
-`PATH'
- The full path names to files, including programs.
-
-`PROG'
- The base names of programs.
-
-`MEMBER'
- Members of aggregates.
-
-`SYS'
- Operating system features.
-
-`TYPE'
- C builtin or declared types.
-
-`VAR'
- C variables in libraries.
-
- After the category comes the name of the particular feature being
-tested. Any further words in the macro name indicate particular aspects
-of the feature. For example, `AC_FUNC_UTIME_NULL' checks the behavior
-of the `utime' function when called with a `NULL' pointer.
-
- An internal macro should have a name that starts with an underscore;
-Autoconf internals should therefore start with `_AC_'. Additionally, a
-macro that is an internal subroutine of another macro should have a
-name that starts with an underscore and the name of that other macro,
-followed by one or more words saying what the internal macro does. For
-example, `AC_PATH_X' has internal macros `_AC_PATH_X_XMKMF' and
-`_AC_PATH_X_DIRECT'.

-
-Reporting Messages
-==================
-
- When macros statically diagnose abnormal situations, benign or fatal,
-they should report them using these macros. For dynamic issues, i.e.,
-when `configure' is run, see *Note Printing Messages::.
-
- - Macro: AC_DIAGNOSE (CATEGORY, MESSAGE)
- Report MESSAGE as a warning (or as an error if requested by the
- user) if it falls into the CATEGORY. You are encouraged to use
- standard categories, which currently include:
-
- `all'
- messages that don't fall into one of the following category.
- Use of an empty CATEGORY is equivalent.
-
- `cross'
- related to cross compilation issues.
-
- `obsolete'
- use of an obsolete construct.
-
- `syntax'
- dubious syntactic constructs, incorrectly ordered macro calls.
-
- - Macro: AC_WARNING (MESSAGE)
- Equivalent to `AC_DIAGNOSE([syntax], MESSAGE)', but you are
- strongly encouraged to use a finer grained category.
-
- - Macro: AC_FATAL (MESSAGE)
- Report a severe error MESSAGE, and have `autoconf' die.
-
- When the user runs `autoconf -W error', warnings from `AC_DIAGNOSE'
-and `AC_WARNING' are reported as error, see *Note autoconf Invocation::.

-
-Dependencies Between Macros
-===========================
-
- Some Autoconf macros depend on other macros having been called first
-in order to work correctly. Autoconf provides a way to ensure that
-certain macros are called if needed and a way to warn the user if
-macros are called in an order that might cause incorrect operation.
-
-* Menu:
-
-* Prerequisite Macros:: Ensuring required information
-* Suggested Ordering:: Warning about possible ordering problems
-
-
-File: autoconf.info, Node: Prerequisite Macros, Next: Suggested Ordering, Prev: Dependencies Between Macros, Up: Dependencies Between Macros
-
-Prerequisite Macros
--------------------
-
- A macro that you write might need to use values that have previously
-been computed by other macros. For example, `AC_DECL_YYTEXT' examines
-the output of `flex' or `lex', so it depends on `AC_PROG_LEX' having
-been called first to set the shell variable `LEX'.
-
- Rather than forcing the user of the macros to keep track of the
-dependencies between them, you can use the `AC_REQUIRE' macro to do it
-automatically. `AC_REQUIRE' can ensure that a macro is only called if
-it is needed, and only called once.
-
- - Macro: AC_REQUIRE (MACRO-NAME)
- If the M4 macro MACRO-NAME has not already been called, call it
- (without any arguments). Make sure to quote MACRO-NAME with
- square brackets. MACRO-NAME must have been defined using
- `AC_DEFUN' or else contain a call to `AC_PROVIDE' to indicate that
- it has been called.
-
- `AC_REQUIRE' must be used inside an `AC_DEFUN''d macro; it must
- not be called from the top level.
-
- `AC_REQUIRE' is often misunderstood. It really implements
-dependencies between macros in the sense that if one macro depends upon
-another, the latter will be expanded _before_ the body of the former.
-In particular, `AC_REQUIRE(FOO)' is not replaced with the body of
-`FOO'. For instance, this definition of macros:
-
- AC_DEFUN([TRAVOLTA],
- [test "$body_temparature_in_celsius" -gt "38" &&
- dance_floor=occupied])
- AC_DEFUN([NEWTON_JOHN],
- [test "$hair_style" = "curly" &&
- dance_floor=occupied])
-
- AC_DEFUN([RESERVE_DANCE_FLOOR],
- [if date | grep '^Sat.*pm' >/dev/null 2>&1; then
- AC_REQUIRE([TRAVOLTA])
- AC_REQUIRE([NEWTON_JOHN])
- fi])
-
-with this `configure.ac'
-
- AC_INIT
- RESERVE_DANCE_FLOOR
- if test "$dance_floor" = occupied; then
- AC_MSG_ERROR([cannot pick up here, let's move])
- fi
-
-will not leave you with a better chance to meet a kindred soul at other
-times than Saturday night since it expands into:
-
- test "$body_temperature_in_Celsius" -gt "38" &&
- dance_floor=occupied
- test "$hair_style" = "curly" &&
- dance_floor=occupied
- fi
- if date | grep '^Sat.*pm' >/dev/null 2>&1; then
-
-
- fi
-
- This behavior was chosen on purpose: (i) it prevents messages in
-required macros from interrupting the messages in the requiring macros;
-(ii) it avoids bad surprises when shell conditionals are used, as in:
-
- if ...; then
- AC_REQUIRE([SOME_CHECK])
- fi
- ...
- SOME_CHECK
-
- You are encouraged to put all `AC_REQUIRE's at the beginning of a
-macro. You can use `dnl' to avoid the empty lines they leave.
-
-
-File: autoconf.info, Node: Suggested Ordering, Prev: Prerequisite Macros, Up: Dependencies Between Macros
-
-Suggested Ordering
-------------------
-
- Some macros should be run before another macro if both are called,
-but neither _requires_ that the other be called. For example, a macro
-that changes the behavior of the C compiler should be called before any
-macros that run the C compiler. Many of these dependencies are noted in
-the documentation.
-
- Autoconf provides the `AC_BEFORE' macro to warn users when macros
-with this kind of dependency appear out of order in a `configure.ac'
-file. The warning occurs when creating `configure' from
-`configure.ac', not when running `configure'.
-
- For example, `AC_PROG_CPP' checks whether the C compiler can run the
-C preprocessor when given the `-E' option. It should therefore be
-called after any macros that change which C compiler is being used,
-such as `AC_PROG_CC'. So `AC_PROG_CC' contains:
-
- AC_BEFORE([$0], [AC_PROG_CPP])dnl
-
-This warns the user if a call to `AC_PROG_CPP' has already occurred
-when `AC_PROG_CC' is called.
-
- - Macro: AC_BEFORE (THIS-MACRO-NAME, CALLED-MACRO-NAME)
- Make `m4' print a warning message to the standard error output if
- CALLED-MACRO-NAME has already been called. THIS-MACRO-NAME should
- be the name of the macro that is calling `AC_BEFORE'. The macro
- CALLED-MACRO-NAME must have been defined using `AC_DEFUN' or else
- contain a call to `AC_PROVIDE' to indicate that it has been called.

-Obsoleting Macros
-=================
-
- Configuration and portability technology has evolved over the years.
-Often better ways of solving a particular problem are developed, or
-ad-hoc approaches are systematized. This process has occurred in many
-parts of Autoconf. One result is that some of the macros are now
-considered "obsolete"; they still work, but are no longer considered
-the best thing to do, hence they should be replaced with more modern
-macros. Ideally, `autoupdate' should substitute the old macro calls
-with their modern implementation.
-
- Autoconf provides a simple means to obsolete a macro.
-
- - Macro: AU_DEFUN (OLD-MACRO, IMPLEMENTATION, [MESSAGE])
- Define OLD-MACRO as IMPLEMENTATION. The only difference with
- `AC_DEFUN' is that the user will be warned that OLD-MACRO is now
- obsolete.
-
- If she then uses `autoupdate', the call to OLD-MACRO will be
- replaced by the modern IMPLEMENTATION. The additional MESSAGE is
- then printed.
-
-
-File: autoconf.info, Node: Coding Style, Prev: Obsoleting Macros, Up: Writing Autoconf Macros
-
-Coding Style
-============
-
- The Autoconf macros follow a strict coding style. You are
-encouraged to follow this style, especially if you intend to distribute
-your macro, either by contributing it to Autoconf itself, or via other
-means.
-
- The first requirement is to pay great attention to the quotation, for
-more details, see *Note Autoconf Language::, and *Note M4 Quotation::.
-
- Do not try to invent new interfaces. It is likely that there is a
-macro in Autoconf that resembles the macro you are defining: try to
-stick to this existing interface (order of arguments, default values,
-etc.). We _are_ conscious that some of these interfaces are not
-perfect; nevertheless, when harmless, homogeneity should be preferred
-over creativity.
-
- Be careful about clashes both between M4 symbols and between shell
-variables.
-
- If you stick to the suggested M4 naming scheme (*note Macro Names::),
-you are unlikely to generate conflicts. Nevertheless, when you need to
-set a special value, _avoid using a regular macro name_; rather, use an
-"impossible" name. For instance, up to version 2.13, the macro
-`AC_SUBST' used to remember what SYMBOLs were already defined by
-setting `AC_SUBST_SYMBOL', which is a regular macro name. But since
-there is a macro named `AC_SUBST_FILE', it was just impossible to
-`AC_SUBST(FILE)'! In this case, `AC_SUBST(SYMBOL)' or
-`_AC_SUBST(SYMBOL)' should have been used (yes, with the
-parentheses)...or better yet, high-level macros such as
-`AC_EXPAND_ONCE'.
-
- No Autoconf macro should ever enter the user-variable name space;
-i.e., except for the variables that are the actual result of running the
-macro, all shell variables should start with `ac_'. In addition, small
-macros or any macro that is likely to be embedded in other macros
-should be careful not to use obvious names.
-
- Do not use `dnl' to introduce comments: most of the comments you are
-likely to write are either header comments which are not output anyway,
-or comments that should make their way into `configure'. There are
-exceptional cases where you do want to comment special M4 constructs,
-in which case `dnl' is right, but keep in mind that it is unlikely.
-
- M4 ignores the leading spaces before each argument, use this feature
-to indent in such a way that arguments are (more or less) aligned with
-the opening parenthesis of the macro being called. For instance,
-instead of
-
- AC_CACHE_CHECK(for EMX OS/2 environment,
- ac_cv_emxos2,
- [AC_COMPILE_IFELSE([AC_LANG_PROGRAM(, [return __EMX__;])],
- [ac_cv_emxos2=yes], [ac_cv_emxos2=no])])
-
-write
-
- AC_CACHE_CHECK([for EMX OS/2 environment], [ac_cv_emxos2],
- [AC_COMPILE_IFELSE([AC_LANG_PROGRAM([], [return __EMX__;])],
- [ac_cv_emxos2=yes],
- [ac_cv_emxos2=no])])
-
-or even
-
- AC_CACHE_CHECK([for EMX OS/2 environment],
- [ac_cv_emxos2],
- [AC_COMPILE_IFELSE([AC_LANG_PROGRAM([],
- [return __EMX__;])],
- [ac_cv_emxos2=yes],
- [ac_cv_emxos2=no])])
-
- When using `AC_TRY_RUN' or any macro that cannot work when
-cross-compiling, provide a pessimistic value (typically `no').
-
- Feel free to use various tricks to prevent auxiliary tools, such as
-syntax-highlighting editors, from behaving improperly. For instance,
-instead of:
-
- patsubst([$1], [$"])
-
-use
-
- patsubst([$1], [$""])
-
-so that Emacsen do not open a endless "string" at the first quote. For
-the same reasons, avoid:
-
- test $[#] != 0
-
-and use:
-
- test $[@%:@] != 0
-
-Otherwise, the closing bracket would be hidden inside a `#'-comment,
-breaking the bracket-matching highlighting from Emacsen. Note the
-preferred style to escape from M4: `$[1]', `$[@]', etc. Do not escape
-when it is unneeded. Common examples of useless quotation are `[$]$1'
-(write `$$1'), `[$]var' (use `$var'), etc. If you add portability
-issues to the picture, you'll prefer `${1+"$[@]"}' to `"[$]@"', and
-you'll prefer do something better than hacking Autoconf `:-)'.
-
- When using `sed', don't use `-e' except for indenting purpose. With
-the `s' command, the preferred separator is `/' unless `/' itself is
-used in the command, in which case you should use `,'.
-
- *Note Macro Definitions::, for details on how to define a macro. If
-a macro doesn't use `AC_REQUIRE' and it is expected to never be the
-object of an `AC_REQUIRE' directive, then use `define'. In case of
-doubt, use `AC_DEFUN'. All the `AC_REQUIRE' statements should be at
-the beginning of the macro, `dnl''ed.
-
- You should not rely on the number of arguments: instead of checking
-whether an argument is missing, test that it is not empty. It provides
-both a simpler and a more predictable interface to the user, and saves
-room for further arguments.
-
- Unless the macro is short, try to leave the closing `])' at the
-beginning of a line, followed by a comment that repeats the name of the
-macro being defined. This introduces an additional newline in
-`configure'; normally, that is not a problem, but if you want to remove
-it you can use `[]dnl' on the last line. You can similarly use `[]dnl'
-after a macro call to remove its newline. `[]dnl' is recommended
-instead of `dnl' to ensure that M4 does not interpret the `dnl' as
-being attached to the preceding text or macro output. For example,
-instead of:
-
- AC_DEFUN([AC_PATH_X],
- [AC_MSG_CHECKING([for X])
- AC_REQUIRE_CPP()
- # ...omitted...
- AC_MSG_RESULT([libraries $x_libraries, headers $x_includes])
- fi])
-
-you would write:
-
- AC_DEFUN([AC_PATH_X],
- [AC_REQUIRE_CPP()[]dnl
- AC_MSG_CHECKING([for X])
- # ...omitted...
- AC_MSG_RESULT([libraries $x_libraries, headers $x_includes])
- fi[]dnl
- ])# AC_PATH_X
-
- If the macro is long, try to split it into logical chunks.
-Typically, macros that check for a bug in a function and prepare its
-`AC_LIBOBJ' replacement should have an auxiliary macro to perform this
-setup. Do not hesitate to introduce auxiliary macros to factor your
-code.
-
- In order to highlight the recommended coding style, here is a macro
-written the old way:
-
- dnl Check for EMX on OS/2.
- dnl _AC_EMXOS2
- AC_DEFUN(_AC_EMXOS2,
- [AC_CACHE_CHECK(for EMX OS/2 environment, ac_cv_emxos2,
- [AC_COMPILE_IFELSE([AC_LANG_PROGRAM(, return __EMX__;)],
- ac_cv_emxos2=yes, ac_cv_emxos2=no)])
- test "$ac_cv_emxos2" = yes && EMXOS2=yes])
-
-and the new way:
-
- # _AC_EMXOS2
- # ----------
- # Check for EMX on OS/2.
- define([_AC_EMXOS2],
- [AC_CACHE_CHECK([for EMX OS/2 environment], [ac_cv_emxos2],
- [AC_COMPILE_IFELSE([AC_LANG_PROGRAM([], [return __EMX__;])],
- [ac_cv_emxos2=yes],
- [ac_cv_emxos2=no])])
- test "$ac_cv_emxos2" = yes && EMXOS2=yes[]dnl
- ])# _AC_EMXOS2

-Portable Shell Programming
-**************************
-
- When writing your own checks, there are some shell-script programming
-techniques you should avoid in order to make your code portable. The
-Bourne shell and upward-compatible shells like the Korn shell and Bash
-have evolved over the years, but to prevent trouble, do not take
-advantage of features that were added after UNIX version 7, circa 1977.
-You should not use shell functions, aliases, negated character
-classes, or other features that are not found in all Bourne-compatible
-shells; restrict yourself to the lowest common denominator. Even
-`unset' is not supported by all shells! Also, include a space after
-the exclamation point in interpreter specifications, like this:
-
- #! /usr/bin/perl
-
-If you omit the space before the path, then 4.2BSD based systems (such
-as Sequent DYNIX) will ignore the line, because they interpret `#! /'
-as a 4-byte magic number.
-
- The set of external programs you should run in a `configure' script
-is fairly small. *Note Utilities in Makefiles: (standards)Utilities in
-Makefiles, for the list. This restriction allows users to start out
-with a fairly small set of programs and build the rest, avoiding too
-many interdependencies between packages.
-
- Some of these external utilities have a portable subset of features;
-see *Note Limitations of Usual Tools::.

-Shellology
-==========
-
- There are several families of shells, most prominently the Bourne
-family and the C shell family which are deeply incompatible. If you
-want to write portable shell scripts, avoid members of the C shell
-family.
-
- Below we describe some of the members of the Bourne shell family.
-
-Ash
- `ash' is often used on GNU/Linux and BSD systems as a light-weight
- Bourne-compatible shell. Ash 0.2 has some bugs that are fixed in
- the 0.3.x series, but portable shell scripts should workaround
- them, since version 0.2 is still shipped with many GNU/Linux
- distributions.
-
- To be compatible with Ash 0.2:
-
- - don't use `$?' after expanding empty or unset variables:
-
- foo=
- false
- $foo
- echo "Don't use it: $?"
-
- - don't use command substitution within variable expansion:
-
- cat ${FOO=`bar`}
-
- - beware that single builtin substitutions are not performed by
- a sub shell, hence their effect applies to the current shell!
- *Note Shell Substitutions::, item "Command Substitution".
-
-Bash
- To detect whether you are running `bash', test if `BASH_VERSION'
- is set. To disable its extensions and require POSIX
- compatibility, run `set -o posix'. *Note Bash POSIX Mode:
- (bash)Bash POSIX Mode, for details.
-
-`/usr/xpg4/bin/sh' on Solaris
- The POSIX-compliant Bourne shell on a Solaris system is
- `/usr/xpg4/bin/sh' and is part of an extra optional package.
- There is no extra charge for this package, but it is also not part
- of a minimal OS install and therefore some folks may not have it.
-
-Zsh
- To detect whether you are running `zsh', test if `ZSH_VERSION' is
- set. By default `zsh' is _not_ compatible with the Bourne shell:
- you have to run `emulate sh' and set `NULLCMD' to `:'. *Note
- Compatibility: (zsh)Compatibility, for details.
-
- Zsh 3.0.8 is the native `/bin/sh' on Mac OS X 10.0.3.
-
- The following discussion between Russ Allbery and Robert Lipe is
-worth reading:
-
-Russ Allbery:
-
- The GNU assumption that `/bin/sh' is the one and only shell leads
- to a permanent deadlock. Vendors don't want to break user's
- existant shell scripts, and there are some corner cases in the
- Bourne shell that are not completely compatible with a POSIX
- shell. Thus, vendors who have taken this route will _never_
- (OK..."never say never") replace the Bourne shell (as `/bin/sh')
- with a POSIX shell.
-
-Robert Lipe:
-
- This is exactly the problem. While most (at least most System
- V's) do have a bourne shell that accepts shell functions most
- vendor `/bin/sh' programs are not the POSIX shell.
-
- So while most modern systems do have a shell _somewhere_ that
- meets the POSIX standard, the challenge is to find it.

-Here-Documents
-==============
-
- Don't rely on `\' being preserved just because it has no special
-meaning together with the next symbol. in the native `/bin/sh' on
-OpenBSD 2.7 `\"' expands to `"' in here-documents with unquoted
-delimiter. As a general rule, if `\\' expands to `\' use `\\' to get
-`\'.
-
- With OpenBSD 2.7's `/bin/sh'
-
- $ cat <<EOF
- > \" \\
- > EOF
- " \
-
-and with Bash:
-
- bash-2.04$ cat <<EOF
- > \" \\
- > EOF
- \" \
-
- Many older shells (including the Bourne shell) implement
-here-documents inefficiently. Users can generally speed things up by
-using a faster shell, e.g., by using the command `bash ./configure'
-rather than plain `./configure'.
-
- Some shells can be extremely inefficient when there are a lot of
-here-documents inside a single statement. For instance if your
-`configure.ac' includes something like:
-
- if <cross_compiling>; then
- assume this and that
- else
- check this
- check that
- check something else
- ...
- on and on forever
- ...
- fi
-
- A shell parses the whole `if'/`fi' construct, creating temporary
-files for each here document in it. Some shells create links for such
-here-documents on every `fork', so that the clean-up code they had
-installed correctly removes them. It is creating the links that the
-shell can take forever.
-
- Moving the tests out of the `if'/`fi', or creating multiple
-`if'/`fi' constructs, would improve the performance significantly.
-Anyway, this kind of construct is not exactly the typical use of
-Autoconf. In fact, it's even not recommended, because M4 macros can't
-look into shell conditionals, so we may fail to expand a macro when it
-was expanded before in a conditional path, and the condition turned out
-to be false at run-time, and we end up not executing the macro at all.

-================

- some systems may open it to `/dev/tty'.

- used on the Kubota Titan.

- Don't redirect several times the same file descriptor, as you are

- $ eval '(echo matter >fullness)' >void

- Ambiguous output redirect.
-
-In each case the expected result is of course `fullness' containing
-`matter' and `void' being empty.
-
- Don't try to redirect the standard error of a command substitution:
-it must be done _inside_ the command substitution: when running `: `cd
-/zorglub` 2>/dev/null' expect the error message to escape, while `: `cd
-/zorglub 2>/dev/null`' works properly.
-
- It is worth noting that Zsh (but not Ash nor Bash) makes it possible
-in assignments though: `foo=`cd /zorglub` 2>/dev/null'.
-
- Most shells, if not all (including Bash, Zsh, Ash), output traces on
-stderr, even for sub-shells. This might result in undesired content if
-you meant to capture the standard-error output of the inner command:
-
- $ ash -x -c '(eval "echo foo >&2") 2>stderr'
- $ cat stderr

- + echo foo

- $ bash -x -c '(eval "echo foo >&2") 2>stderr'

-
-File System Conventions
-=======================
-
- While `autoconf' and friends will usually be run on some Unix
-variety, it can and will be used on other systems, most notably DOS
-variants. This impacts several assumptions regarding file and path
-names.
-
-For example, the following code:
-
- case $foo_dir in
- /*) # Absolute
- ;;
- *)
- foo_dir=$dots$foo_dir ;;
- esac
-
-will fail to properly detect absolute paths on those systems, because
-they can use a drivespec, and will usually use a backslash as directory
-separator. The canonical way to check for absolute paths is:
-
- case $foo_dir in
- [\\/]* | ?:[\\/]* ) # Absolute
- ;;
- *)
- foo_dir=$dots$foo_dir ;;
- esac
-
-Make sure you quote the brackets if appropriate and keep the backslash
-as first character (*note Limitations of Builtins::).
-
- Also, because the colon is used as part of a drivespec, these
-systems don't use it as path separator. When creating or accessing
-paths, use `$ac_path_separator' instead (or the `PATH_SEPARATOR' output
-variable). `autoconf' sets this to the appropriate value (`:' or `;')
-when it starts up.
-
- File names need extra care as well. While DOS-based environments
-that are Unixy enough to run `autoconf' (such as DJGPP) will usually be
-able to handle long file names properly, there are still limitations
-that can seriously break packages. Several of these issues can be
-easily detected by the doschk(1) package.
-
- A short overview follows; problems are marked with SFN/LFN to
-indicate where they apply: SFN means the issues are only relevant to
-plain DOS, not to DOS boxes under Windows, while LFN identifies
-problems that exist even under Windows.
-
-No multiple dots (SFN)
- DOS cannot handle multiple dots in filenames. This is an
- especially important thing to remember when building a portable
- configure script, as `autoconf' uses a .in suffix for template
- files.
-
- This is perfectly OK on Unices:
-
- AC_CONFIG_HEADER(config.h)
- AC_CONFIG_FILES([source.c foo.bar])
- AC_OUTPUT
-
- but it causes problems on DOS, as it requires `config.h.in',
- `source.c.in' and `foo.bar.in'. To make your package more portable
- to DOS-based environments, you should use this instead:
-
- AC_CONFIG_HEADER(config.h:config.hin)
- AC_CONFIG_FILES([source.c:source.cin foo.bar:foobar.in])
- AC_OUTPUT
-
-No leading dot (SFN)
- DOS cannot handle filenames that start with a dot. This is usually
- not a very important issue for `autoconf'.
-
-Case insensitivity (LFN)
- DOS is case insensitive, so you cannot, for example, have both a
- file called `INSTALL' and a directory called `install'. This also
- affects `make'; if there's a file called `INSTALL' in the
- directory, `make install' will do nothing (unless the `install'
- target is marked as PHONY).
-
-The 8+3 limit (SFN)
- Because the DOS file system only stores the first 8 characters of
- the filename and the first 3 of the extension, those must be
- unique. That means that `foobar-part1.c', `foobar-part2.c' and
- `foobar-prettybird.c' all resolve to the same filename
- (`FOOBAR-P.C'). The same goes for `foo.bar' and `foo.bartender'.
-
- Note: This is not usually a problem under Windows, as it uses
- numeric tails in the short version of filenames to make them
- unique. However, a registry setting can turn this behaviour off.
- While this makes it possible to share file trees containing long
- file names between SFN and LFN environments, it also means the
- above problem applies there as well.
-
-Invalid characters
- Some characters are invalid in DOS filenames, and should therefore
- be avoided. In a LFN environment, these are `/', `\', `?', `*',
- `:', `<', `>', `|' and `"'. In a SFN environment, other
- characters are also invalid. These include `+', `,', `[' and `]'.

-
-Shell Substitutions
-===================
-
- Contrary to a persistent urban legend, the Bourne shell does not
-systematically split variables and backquoted expressions, in particular
-on the right-hand side of assignments and in the argument of `case'.
-For instance, the following code:
-
- case "$given_srcdir" in
- .) top_srcdir="`echo "$dots" | sed 's,/$,,'`"
- *) top_srcdir="$dots$given_srcdir" ;;
- esac
-
-is more readable when written as:
-
- case $given_srcdir in
- .) top_srcdir=`echo "$dots" | sed 's,/$,,'`
- *) top_srcdir=$dots$given_srcdir ;;
- esac
-
-and in fact it is even _more_ portable: in the first case of the first
-attempt, the computation of `top_srcdir' is not portable, since not all
-shells properly understand `"`..."..."...`"'. Worse yet, not all
-shells understand `"`...\"...\"...`"' the same way. There is just no
-portable way to use double-quoted strings inside double-quoted
-backquoted expressions (pfew!).
-
-`$@'
- One of the most famous shell-portability issues is related to
- `"$@"': when there are no positional arguments, it is supposed to
- be equivalent to nothing. But some shells, for instance under
- Digital Unix 4.0 and 5.0, will then replace it with an empty
- argument. To be portable, use `${1+"$@"}'.
-
-`${VAR:-VALUE}'
- Old BSD shells, including the Ultrix `sh', don't accept the colon
- for any shell substitution, and complain and die.
-
-`${VAR=LITERAL}'
- Be sure to quote:
-
- : ${var='Some words'}
-
- otherwise some shells, such as on Digital Unix V 5.0, will die
- because of a "bad substitution".
-
- Solaris' `/bin/sh' has a frightening bug in its interpretation of
- this. Imagine you need set a variable to a string containing `}'.
- This `}' character confuses Solaris' `/bin/sh' when the affected
- variable was already set. This bug can be exercised by running:
-
- $ unset foo
- $ foo=${foo='}'}
- $ echo $foo
- }
- $ foo=${foo='}' # no error; this hints to what the bug is
- $ echo $foo
- }
- $ foo=${foo='}'}
- $ echo $foo
- }}
- ^ ugh!
-
- It seems that `}' is interpreted as matching `${', even though it
- is enclosed in single quotes. The problem doesn't happen using
- double quotes.
-
-`${VAR=EXPANDED-VALUE}'
- On Ultrix, running
-
- default="yu,yaa"
- : ${var="$default"}
-
- will set VAR to `M-yM-uM-,M-yM-aM-a', i.e., the 8th bit of each
- char will be set. You won't observe the phenomenon using a simple
- `echo $var' since apparently the shell resets the 8th bit when it
- expands $var. Here are two means to make this shell confess its
- sins:
-
- $ cat -v <<EOF
- $var
- EOF
-
- and
-
- $ set | grep '^var=' | cat -v
-
- One classic incarnation of this bug is:
-
- default="a b c"
- : ${list="$default"}
- for c in $list; do
- echo $c
- done
-
- You'll get `a b c' on a single line. Why? Because there are no
- spaces in `$list': there are `M- ', i.e., spaces with the 8th bit
- set, hence no IFS splitting is performed!!!
-
- One piece of good news is that Ultrix works fine with `:
- ${list=$default}'; i.e., if you _don't_ quote. The bad news is
- then that QNX 4.25 then sets LIST to the _last_ item of DEFAULT!
-
- The portable way out consists in using a double assignment, to
- switch the 8th bit twice on Ultrix:
-
- list=${list="$default"}
-
- ...but beware of the `}' bug from Solaris (see above). For safety,
- use:
-
- test "${var+set}" = set || var={VALUE}
-
-``COMMANDS`'
- While in general it makes no sense, do not substitute a single
- builtin with side effects as Ash 0.2, trying to optimize, does not
- fork a sub-shell to perform the command.
-
- For instance, if you wanted to check that `cd' is silent, do not
- use `test -z "`cd /`"' because the following can happen:
-
- $ pwd
- /tmp
- $ test -n "`cd /`" && pwd
- /
-
- The result of `foo=`exit 1`' is left as an exercise to the reader.
-
-`$(COMMANDS)'
- This construct is meant to replace ``COMMANDS`'; they can be
- nested while this is impossible to do portably with back quotes.
- Unfortunately it is not yet widely supported. Most notably, even
- recent releases of Solaris don't support it:
-
- $ showrev -c /bin/sh | grep version
- Command version: SunOS 5.8 Generic 109324-02 February 2001
- $ echo $(echo blah)
- syntax error: `(' unexpected
-
- nor does IRIX 6.5's Bourne shell:
- $ uname -a
- IRIX firebird-image 6.5 07151432 IP22
- $ echo $(echo blah)
- $(echo blah)

-
-Assignments
-===========
-
- When setting several variables in a row, be aware that the order of
-the evaluation is undefined. For instance `foo=1 foo=2; echo $foo'
-gives `1' with sh on Solaris, but `2' with Bash. You must use `;' to
-enforce the order: `foo=1; foo=2; echo $foo'.
-
- Don't rely on the exit status of an assignment: Ash 0.2 does not
-change the status and propagates that of the last statement:
-
- $ false || foo=bar; echo $?
- 1
- $ false || foo=`:`; echo $?
- 0
-
-and to make things even worse, QNX 4.25 just sets the exit status to 0
-in any case:
-
- $ foo=`exit 1`; echo $?
- 0
-
- To assign default values, follow this algorithm:
-
- 1. If the default value is a literal and does not contain any closing
- brace, use:
-
- : ${var='my literal'}
-
- 2. If the default value contains no closing brace, has to be
- expanded, and the variable being initialized will never be
- IFS-split (i.e., it's not a list), then use:
-
- : ${var="$default"}
-
- 3. If the default value contains no closing brace, has to be
- expanded, and the variable being initialized will be IFS-split
- (i.e., it's a list), then use:
-
- var=${var="$default"}
-
- 4. If the default value contains a closing brace, then use:
-
- test "${var+set}" = set || var='${indirection}'
-
- In most cases `var=${var="$default"}' is fine, but in case of doubt,
-just use the latter. *Note Shell Substitutions::, items
-`${VAR:-VALUE}' and `${VAR=VALUE}' for the rationale.

-
-Special Shell Variables
-=======================
-
- Some shell variables should not be used, since they can have a deep
-influence on the behavior of the shell. In order to recover a sane
-behavior from the shell, some variables should be unset, but `unset' is
-not portable (*note Limitations of Builtins::) and a fallback value is
-needed. We list these values below.
-
-`CDPATH'
- When this variable is set `cd' is verbose, so idioms such as
- `abs=`cd $rel && pwd`' break because `abs' receives the path twice.
-
- Setting `CDPATH' to the empty value is not enough for most shells.
- A simple colon is enough except for `zsh', which prefers a leading
- dot:
-
- zsh-3.1.6 % mkdir foo && (CDPATH=: cd foo)
- /tmp/foo
- zsh-3.1.6 % (CDPATH=:. cd foo)
- /tmp/foo
- zsh-3.1.6 % (CDPATH=.: cd foo)
- zsh-3.1.6 %
-
- (of course we could just `unset' `CDPATH', since it also behaves
- properly if set to the empty string).
-
- Life wouldn't be so much fun if `bash' and `zsh' had the same
- behavior:
-
- bash-2.02 % (CDPATH=:. cd foo)
- bash-2.02 % (CDPATH=.: cd foo)
- /tmp/foo
-
- Therefore, a portable solution to neutralize `CDPATH' is
-
- CDPATH=${ZSH_VERSION+.}:
-
- Note that since `zsh' supports `unset', you may unset `CDPATH'
- using `:' as a fallback, see *Note Limitations of Builtins::.
-
-`IFS'
- Don't set the first character of `IFS' to backslash. Indeed,
- Bourne shells use the first character (backslash) when joining the
- components in `"$@"' and some shells then re-interpret (!) the
- backslash escapes, so you can end up with backspace and other
- strange characters.
-
-`LANG'
-`LC_ALL'
-`LC_TIME'
-`LC_CTYPE'
-`LANGUAGE'
-`LC_COLLATE'
-`LC_NUMERIC'
-`LC_MESSAGES'
- These must not be set unconditionally because not all systems
- understand e.g. `LANG=C' (notably SCO). Fixing `LC_MESSAGES'
- prevents Solaris `sh' from translating var values in `set'! Non-C
- `LC_CTYPE' values break the ctype check. Fixing `LC_COLLATE'
- makes scripts more portable in some cases. For example, it causes
- the regular expression `[a-z]' to match only lower-case letters on
- ASCII platforms. However, `[a-z]' does not work in general even
- when `LC_COLLATE' is fixed; for example, it does not work for
- EBCDIC platforms. For maximum portability, you should use regular
- expressions like `[abcdefghijklmnopqrstuvwxyz]' that list
- characters explicitly instead of relying on ranges.
-
- _If_ one of these variables is set, you should try to unset it,
- using `C' as a fall back value. see *Note Limitations of
- Builtins::, builtin `unset', for more details.
-
-`NULLCMD'
- When executing the command `>foo', `zsh' executes `$NULLCMD >foo'.
- The Bourne shell considers `NULLCMD' is `:', while `zsh', even in
- Bourne shell compatibility mode, sets `NULLCMD' to `cat'. If you
- forgot to set `NULLCMD', your script might be suspended waiting
- for data on its standard input.
-
-`status'
- This variable is an alias to `$?' for `zsh' (at least 3.1.6),
- hence read-only. Do not use it.
-
-`PATH_SEPARATOR'
- On DJGPP systems, the `PATH_SEPARATOR' variable can be set to
- either `:' or `;' to control the path separator `bash' uses to set
- up certain environment variables (such as `PATH'). Since this only
- works inside bash, you want autoconf to detect the regular DOS
- path separator `;', so it can be safely substituted in files that
- may not support `;' as path separator. So either unset this
- variable or set it to `;'.
-
-`RANDOM'
- Many shells provide `RANDOM', a variable that returns a different
- integer when used. Most of the time, its value does not change
- when it is not used, but on IRIX 6.5 the value changes all the
- time. This can be observed by using `set'.

-
-Limitations of Shell Builtins
-=============================
-
- No, no, we are serious: some shells do have limitations! :)
-
- You should always keep in mind that any built-in or command may
-support options, and therefore have a very different behavior with
-arguments starting with a dash. For instance, the innocent `echo
-"$word"' can give unexpected results when `word' starts with a dash.
-It is often possible to avoid this problem using `echo "x$word"', taking
-the `x' into account later in the pipe.
-
-`!'
- You can't use `!', you'll have to rewrite your code.
-
-`break'
- The use of `break 2', etcetera, is safe.
-
-`case'
- You don't need to quote the argument; no splitting is performed.
-
- You don't need the final `;;', but you should use it.
-
- Because of a bug in its `fnmatch', `bash' fails to properly handle
- backslashes in character classes:
-
- bash-2.02$ case /tmp in [/\\]*) echo OK;; esac
- bash-2.02$
-
- This is extremely unfortunate, since you are likely to use this
- code to handle UNIX or MS-DOS absolute paths. To work around this
- bug, always put the backslash first:
-
- bash-2.02$ case '\TMP' in [\\/]*) echo OK;; esac
- OK
- bash-2.02$ case /tmp in [\\/]*) echo OK;; esac
- OK
-
-`echo'
- The simple `echo' is probably the most surprising source of
- portability troubles. It is not possible to use `echo' portably
- unless both options and escape sequences are omitted. New
- applications which are not aiming at portability should use
- `printf' instead of `echo'.
-
- Don't expect any option. *Note Preset Output Variables::, `ECHO_N'
- etc. for a means to simulate `-c'.
-
- Do not use backslashes in the arguments, as there is no consensus
- on their handling. On `echo '\n' | wc -l', the `sh' of Digital
- Unix 4.0, MIPS RISC/OS 4.52, answer 2, but the Solaris' `sh', Bash
- and Zsh (in `sh' emulation mode) report 1. Please note that the
- problem is truly `echo': all the shells understand `'\n'' as the
- string composed of a backslash and an `n'.
-
- Because of these problems, do not pass a string containing
- arbitrary characters to `echo'. For example, `echo "$foo"' is safe
- if you know that FOO's value cannot contain backslashes and cannot
- start with `-', but otherwise you should use a here-document like
- this:
-
- cat <<EOF
- $foo
- EOF
-
-`exit'
- The default value of `exit' is supposed to be `$?'; unfortunately,
- some shells, such as the DJGPP port of Bash 2.04, just perform
- `exit 0'.
-
- bash-2.04$ foo=`exit 1` || echo fail
- fail
- bash-2.04$ foo=`(exit 1)` || echo fail
- fail
- bash-2.04$ foo=`(exit 1); exit` || echo fail
- bash-2.04$
-
- Using `exit $?' restores the expected behavior.
-
- Some shell scripts, such as those generated by `autoconf', use a
- trap to clean up before exiting. If the last shell command exited
- with nonzero status, the trap also exits with nonzero status so
- that the invoker can tell that an error occurred.
-
- Unfortunately, in some shells, such as Solaris 8 `sh', an exit
- trap ignores the `exit' command's status. In these shells, a trap
- cannot determine whether it was invoked by plain `exit' or by
- `exit 1'. Instead of calling `exit' directly, use the
- `AC_MSG_ERROR' macro that has a workaround for this problem.
-
-`export'
- The builtin `export' dubs "environment variable" a shell variable.
- Each update of exported variables corresponds to an update of the
- environment variables. Conversely, each environment variable
- received by the shell when it is launched should be imported as a
- shell variable marked as exported.
-
- Alas, many shells, such as Solaris 2.5, IRIX 6.3, IRIX 5.2, AIX
- 4.1.5 and DU 4.0, forget to `export' the environment variables they
- receive. As a result, two variables are coexisting: the
- environment variable and the shell variable. The following code
- demonstrates this failure:
-
- #! /bin/sh
- echo $FOO
- FOO=bar
- echo $FOO
- exec /bin/sh $0
-
- when run with `FOO=foo' in the environment, these shells will print
- alternately `foo' and `bar', although it should only print `foo'
- and then a sequence of `bar's.
-
- Therefore you should `export' again each environment variable that
- you update.
-
-`false'
- Don't expect `false' to exit with status 1: in the native Bourne
- shell of Solaris 8, it exits with status 255.
-
-`for'
- To loop over positional arguments, use:
-
- for arg
- do
- echo "$arg"
- done
-
- You may _not_ leave the `do' on the same line as `for', since some
- shells improperly grok:
-
- for arg; do
- echo "$arg"
- done
-
- If you want to explicitly refer to the positional arguments, given
- the `$@' bug (*note Shell Substitutions::), use:
-
- for arg in ${1+"$@"}; do
- echo "$arg"
- done
-
-`if'
- Using `!' is not portable. Instead of:
-
- if ! cmp -s file file.new; then
- mv file.new file
- fi
-
- use:
-
- if cmp -s file file.new; then :; else
- mv file.new file
- fi
-
- There are shells that do not reset the exit status from an `if':
-
- $ if (exit 42); then true; fi; echo $?
- 42
-
- whereas a proper shell should have printed `0'. This is especially
- bad in Makefiles since it produces false failures. This is why
- properly written Makefiles, such as Automake's, have such hairy
- constructs:
-
- if test -f "$file"; then
- install "$file" "$dest"
- else
- :
- fi
-
-`set'
- This builtin faces the usual problem with arguments starting with a
- dash. Modern shells such as Bash or Zsh understand `--' to specify
- the end of the options (any argument after `--' is a parameters,
- even `-x' for instance), but most shells simply stop the option
- processing as soon as a non-option argument is found. Therefore,
- use `dummy' or simply `x' to end the option processing, and use
- `shift' to pop it out:
-
- set x $my_list; shift
-
-`shift'
- Not only is `shift'ing a bad idea when there is nothing left to
- shift, but in addition it is not portable: the shell of MIPS
- RISC/OS 4.52 refuses to do it.
-
-`test'
- The `test' program is the way to perform many file and string
- tests. It is often invoked by the alternate name `[', but using
- that name in Autoconf code is asking for trouble since it is an M4
- quote character.
-
- If you need to make multiple checks using `test', combine them with
- the shell operators `&&' and `||' instead of using the `test'
- operators `-a' and `-o'. On System V, the precedence of `-a' and
- `-o' is wrong relative to the unary operators; consequently, POSIX
- does not specify them, so using them is nonportable. If you
- combine `&&' and `||' in the same statement, keep in mind that
- they have equal precedence.
-
- You may use `!' with `test', but not with `if': `test ! -r foo ||
- exit 1'.
-
-`test' (files)
- To enable `configure' scripts to support cross-compilation, they
- shouldn't do anything that tests features of the build system
- instead of the host system. But occasionally you may find it
- necessary to check whether some arbitrary file exists. To do so,
- use `test -f' or `test -r'. Do not use `test -x', because 4.3BSD
- does not have it. Do not use `test -e' either, because Solaris
- 2.5 does not have it.
-
-`test' (strings)
- Avoid `test "STRING"', in particular if STRING might start with a
- dash, since `test' might interpret its argument as an option
- (e.g., `STRING = "-n"').
-
- Contrary to a common belief, `test -n STRING' and `test -z STRING'
- *are* portable, nevertheless many shells (such as Solaris 2.5, AIX
- 3.2, UNICOS 10.0.0.6, Digital Unix 4 etc.) have bizarre precedence
- and may be confused if STRING looks like an operator:
-
- $ test -n =
- test: argument expected
-
- If there are risks, use `test "xSTRING" = x' or `test "xSTRING" !=
- x' instead.
-
- It is frequent to find variations of the following idiom:
-
- test -n "`echo $ac_feature | sed 's/[-a-zA-Z0-9_]//g'`" &&
- ACTION
-
- to take an action when a token matches a given pattern. Such
- constructs should always be avoided by using:
-
- echo "$ac_feature" | grep '[^-a-zA-Z0-9_]' >/dev/null 2>&1 &&
- ACTION
-
- Use `case' where possible since it is faster, being a shell
- builtin:
-
- case $ac_feature in
- *[!-a-zA-Z0-9_]*) ACTION;;
- esac
-
- Alas, negated character classes are probably not portable,
- although no shell is known to not support the POSIX.2 syntax
- `[!...]' (when in interactive mode, `zsh' is confused by the
- `[!...]' syntax and looks for an event in its history because of
- `!'). Many shells do not support the alternative syntax `[^...]'
- (Solaris, Digital Unix, etc.).
-
- One solution can be:
-
- expr "$ac_feature" : '.*[^-a-zA-Z0-9_]' >/dev/null &&
- ACTION
-
- or better yet
-
- expr "x$ac_feature" : '.*[^-a-zA-Z0-9_]' >/dev/null &&
- ACTION
-
- `expr "XFOO" : "XBAR"' is more robust than `echo "XFOO" | grep
- "^XBAR"', because it avoids problems when `FOO' contains
- backslashes.
-
-`trap'
- It is safe to trap at least the signals 1, 2, 13 and 15. You can
- also trap 0, i.e., have the `trap' run when the script ends
- (either via an explicit `exit', or the end of the script).
-
- Although POSIX is not absolutely clear on this point, it is widely
- admitted that when entering the trap `$?' should be set to the exit
- status of the last command run before the trap. The ambiguity can
- be summarized as: "when the trap is launched by an `exit', what is
- the _last_ command run: that before `exit', or `exit' itself?"
-
- Bash considers `exit' to be the last command, while Zsh and
- Solaris 8 `sh' consider that when the trap is run it is _still_ in
- the `exit', hence it is the previous exit status that the trap
- receives:
-
- $ cat trap.sh
- trap 'echo $?' 0
- (exit 42); exit 0
- $ zsh trap.sh
- 42
- $ bash trap.sh
- 0
-
- The portable solution is then simple: when you want to `exit 42',
- run `(exit 42); exit 42', the first `exit' being used to set the
- exit status to 42 for Zsh, and the second to trigger the trap and
- pass 42 as exit status for Bash.
-
- The shell in FreeBSD 4.0 has the following bug: `$?' is reset to 0
- by empty lines if the code is inside `trap'.
-
- $ trap 'false
-
- echo $?' 0
- $ exit
- 0
-
- Fortunately, this bug only affects `trap'.
-
-`true'
- Don't worry: as far as we know `true' is portable. Nevertheless,
- it's not always a builtin (e.g., Bash 1.x), and the portable shell
- community tends to prefer using `:'. This has a funny side
- effect: when asked whether `false' is more portable than `true'
- Alexandre Oliva answered:
-
- In a sense, yes, because if it doesn't exist, the shell will
- produce an exit status of failure, which is correct for
- `false', but not for `true'.
-
-`unset'
- You cannot assume the support of `unset', nevertheless, because it
- is extremely useful to disable embarrassing variables such as
- `CDPATH' or `LANG', you can test for its existence and use it
- _provided_ you give a neutralizing value when `unset' is not
- supported:
-
- if (unset FOO) >/dev/null 2>&1; then
- unset=unset
- else
- unset=false
- fi
- $unset CDPATH || CDPATH=:
-
- *Note Special Shell Variables::, for some neutralizing values.
- Also, see *Note Limitations of Builtins::, documentation of
- `export', for the case of environment variables.

-
-Limitations of Usual Tools
-==========================
-
- The small set of tools you can expect to find on any machine can
-still include some limitations you should be aware of.
-
-`awk'
- Don't leave white spaces before the parentheses in user functions
- calls, GNU awk will reject it:
-
- $ gawk 'function die () { print "Aaaaarg!" }
- BEGIN { die () }'
- gawk: cmd. line:2: BEGIN { die () }
- gawk: cmd. line:2: ^ parse error
- $ gawk 'function die () { print "Aaaaarg!" }
- BEGIN { die() }'
- Aaaaarg!
-
- If you want your program to be deterministic, don't depend on `for'
- on arrays:
-
- $ cat for.awk
- END {
- arr["foo"] = 1
- arr["bar"] = 1
- for (i in arr)
- print i
- }
- $ gawk -f for.awk </dev/null
- foo
- bar
- $ nawk -f for.awk </dev/null
- bar
- foo
-
- Some AWK, such as HPUX 11.0's native one, have regex engines
- fragile to inner anchors:
-
- $ echo xfoo | $AWK '/foo|^bar/ { print }'
- $ echo bar | $AWK '/foo|^bar/ { print }'
- bar
- $ echo xfoo | $AWK '/^bar|foo/ { print }'
- xfoo
- $ echo bar | $AWK '/^bar|foo/ { print }'
- bar
-
- Either do not depend on such patterns (i.e., use `/^(.*foo|bar)/',
- or use a simple test to reject such AWK.
-
-`cat'
- Don't rely on any option. The option `-v', which displays
- non-printing characters, _seems_ portable, though.
-
-`cc'
- When a compilation such as `cc foo.c -o foo' fails, some compilers
- (such as CDS on Reliant UNIX) leave a `foo.o'.
-
-`cmp'
- `cmp' performs a raw data comparison of two files, while `diff'
- compares two text files. Therefore, if you might compare DOS
- files, even if only checking whether two files are different, use
- `diff' to avoid spurious differences due to differences of newline
- encoding.
-
-`cp'
- SunOS `cp' does not support `-f', although its `mv' does. It's
- possible to deduce why `mv' and `cp' are different with respect to
- `-f'. `mv' prompts by default before overwriting a read-only
- file. `cp' does not. Therefore, `mv' requires a `-f' option, but
- `cp' does not. `mv' and `cp' behave differently with respect to
- read-only files because the simplest form of `cp' cannot overwrite
- a read-only file, but the simplest form of `mv' can. This is
- because `cp' opens the target for write access, whereas `mv'
- simply calls `link' (or, in newer systems, `rename').
-
-`diff'
- Option `-u' is nonportable.
-
- Some implementations, such as Tru64's, fail when comparing to
- `/dev/null'. Use an empty file instead.
-
-`dirname'
- Not all hosts have `dirname', but it is reasonably easy to
- emulate, e.g.:
-
- dir=`expr "x$file" : 'x\(.*\)/[^/]*' \|
- '.' : '.'
-
- But there are a few subtilities, e.g., under UN*X, should `//1'
- give `/'? Paul Eggert answers:
-
- No, under some older flavors of Unix, leading `//' is a
- special path name: it refers to a "super-root" and is used to
- access other machines' files. Leading `///', `////', etc.
- are equivalent to `/'; but leading `//' is special. I think
- this tradition started with Apollo Domain/OS, an OS that is
- still in use on some older hosts.
-
- POSIX.2 allows but does not require the special treatment for
- `//'. It says that the behavior of dirname on path names of
- the form `//([^/]+/*)?' is implementation defined. In these
- cases, GNU `dirname' returns `/', but it's more portable to
- return `//' as this works even on those older flavors of Unix.
-
- I have heard rumors that this special treatment of `//' may be
- dropped in future versions of POSIX, but for now it's still
- the standard.
-
-`egrep'
- The empty alternative is not portable, use `?' instead. For
- instance with Digital Unix v5.0:
-
- > printf "foo\n|foo\n" | egrep '^(|foo|bar)$'
- |foo
- > printf "bar\nbar|\n" | egrep '^(foo|bar|)$'
- bar|
- > printf "foo\nfoo|\n|bar\nbar\n" | egrep '^(foo||bar)$'
- foo
- |bar
-
- `egrep' also suffers the limitations of `grep'.
-
-`expr'
- No `expr' keyword starts with `x', so use `expr x"WORD" :
- 'xREGEX'' to keep `expr' from misinterpreting WORD.
-
- Don't use `length', `substr', `match' and `index'.
-
-`expr' (`|')
- You can use `|'. Although POSIX does require that `expr '''
- return the empty string, it does not specify the result when you
- `|' together the empty string (or zero) with the empty string. For
- example:
-
- expr '' \| ''
-
- GNU/Linux and POSIX.2-1992 return the empty string for this case,
- but traditional Unix returns `0' (Solaris is one such example).
- In the latest POSIX draft, the specification has been changed to
- match traditional Unix's behavior (which is bizarre, but it's too
- late to fix this). Please note that the same problem does arise
- when the empty string results from a computation, as in:
-
- expr bar : foo \| foo : bar
-
- Avoid this portability problem by avoiding the empty string.
-
-`expr' (`:')
- Don't use `\?', `\+' and `\|' in patterns, they are not supported
- on Solaris.
-
- The POSIX.2-1992 standard is ambiguous as to whether `expr a : b'
- (and `expr 'a' : '\(b\)'') output `0' or the empty string. In
- practice, it outputs the empty string on most platforms, but
- portable scripts should not assume this. For instance, the QNX
- 4.25 native `expr' returns `0'.
-
- You may believe that one means to get a uniform behavior would be
- to use the empty string as a default value:
-
- expr a : b \| ''
-
- unfortunately this behaves exactly as the original expression, see
- the ``expr' (`:')' entry for more information.
-
- Older `expr' implementations (e.g. SunOS 4 `expr' and Solaris 8
- `/usr/ucb/expr') have a silly length limit that causes `expr' to
- fail if the matched substring is longer than 120 bytes. In this
- case, you might want to fall back on `echo|sed' if `expr' fails.
-
- Don't leave, there is some more!
-
- The QNX 4.25 `expr', in addition of preferring `0' to the empty
- string, has a funny behavior in its exit status: it's always 1
- when parentheses are used!
-
- $ val=`expr 'a' : 'a'`; echo "$?: $val"
- 0: 1
- $ val=`expr 'a' : 'b'`; echo "$?: $val"
- 1: 0
-
- $ val=`expr 'a' : '\(a\)'`; echo "?: $val"
- 1: a
- $ val=`expr 'a' : '\(b\)'`; echo "?: $val"
- 1: 0
-
- In practice this can be a big problem if you are ready to catch
- failures of `expr' programs with some other method (such as using
- `sed'), since you may get twice the result. For instance
-
- $ expr 'a' : '\(a\)' || echo 'a' | sed 's/^\(a\)$/\1/'
-
- will output `a' on most hosts, but `aa' on QNX 4.25. A simple
- work around consists in testing `expr' and use a variable set to
- `expr' or to `false' according to the result.
-
-`find'
- The option `-maxdepth' seems to be GNU specific. Tru64 v5.1,
- NetBSD 1.5 and Solaris 2.5 `find' commands do not understand it.
-
-`grep'
- Don't use `grep -s' to suppress output, because `grep -s' on
- System V does not suppress output, only error messages. Instead,
- redirect the standard output and standard error (in case the file
- doesn't exist) of `grep' to `/dev/null'. Check the exit status of
- `grep' to determine whether it found a match.
-
- Don't use multiple regexps with `-e', as some `grep' will only
- honor the last pattern (eg., IRIX 6.5 and Solaris 2.5.1). Anyway,
- Stardent Vistra SVR4 `grep' lacks `-e'... Instead, use
- alternation and `egrep'.
-
-`ln'
- Don't rely on `ln' having a `-f' option. Symbolic links are not
- available on old systems, use `ln' as a fall back.
-
- For versions of the DJGPP before 2.04, `ln' emulates soft links
- for executables by generating a stub that in turn calls the real
- program. This feature also works with nonexistent files like in
- the Unix spec. So `ln -s file link' will generate `link.exe',
- which will attempt to call `file.exe' if run. But this feature only
- works for executables, so `cp -p' is used instead for these
- systems. DJGPP versions 2.04 and later have full symlink support.
-
-`mv'
- The only portable options are `-f' and `-i'.
-
- Moving individual files between file systems is portable (it was
- in V6), but it is not always atomic: when doing `mv new existing',
- there's a critical section where neither the old nor the new
- version of `existing' actually exists.
-
- Moving directories across mount points is not portable, use `cp'
- and `rm'.
-
-`sed'
- Patterns should not include the separator (unless escaped), even
- as part of a character class. In conformance with POSIX, the Cray
- `sed' will reject `s/[^/]*$//': use `s,[^/]*$,,'.
-
- Sed scripts should not use branch labels longer than 8 characters
- and should not contain comments.
-
- Don't include extra `;', as some `sed', such as NetBSD 1.4.2's,
- try to interpret the second as a command:
-
- $ echo a | sed 's/x/x/;;s/x/x/'
- sed: 1: "s/x/x/;;s/x/x/": invalid command code ;
-
- Input should have reasonably long lines, since some `sed' have an
- input buffer limited to 4000 bytes.
-
- Alternation, `\|', is common but not portable. Anchors (`^' and
- `$') inside groups are not portable.
-
- Nested groups are extremely portable, but there is at least one
- `sed' (System V/68 Base Operating System R3V7.1) that does not
- support it.
-
- Of course the option `-e' is portable, but it is not needed. No
- valid Sed program can start with a dash, so it does not help
- disambiguating. Its sole usefulness is helping enforcing
- indenting as in:
-
- sed -e INSTRUCTION-1 \
- -e INSTRUCTION-2
-
- as opposed to
-
- sed INSTRUCTION-1;INSTRUCTION-2
-
- Contrary to yet another urban legend, you may portably use `&' in
- the replacement part of the `s' command to mean "what was matched".
-
-`sed' (`t')
- Some old systems have `sed' that "forget" to reset their `t' flag
- when starting a new cycle. For instance on MIPS RISC/OS, and on
- IRIX 5.3, if you run the following `sed' script (the line numbers
- are not actual part of the texts):
-
- s/keep me/kept/g # a
- t end # b
- s/.*/deleted/g # c
- : end # d
-
- on
-
- delete me # 1
- delete me # 2
- keep me # 3
- delete me # 4
-
- you get
-
- deleted
- delete me
- kept
- deleted
-
- instead of
-
- deleted
- deleted
- kept
- deleted
-
- Why? When processing 1, a matches, therefore sets the t flag, b
- jumps to d, and the output is produced. When processing line 2,
- the t flag is still set (this is the bug). Line a fails to match,
- but `sed' is not supposed to clear the t flag when a substitution
- fails. Line b sees that the flag is set, therefore it clears it,
- and jumps to d, hence you get `delete me' instead of `deleted'.
- When processing 3 t is clear, a matches, so the flag is set, hence
- b clears the flags and jumps. Finally, since the flag is clear, 4
- is processed properly.
-
- There are two things one should remind about `t' in `sed'.
- Firstly, always remember that `t' jumps if _some_ substitution
- succeeded, not only the immediately preceding substitution,
- therefore, always use a fake `t clear; : clear' to reset the t
- flag where indeed.
-
- Secondly, you cannot rely on `sed' to clear the flag at each new
- cycle.
-
- One portable implementation of the script above is:
-
- t clear
- : clear
- s/keep me/kept/g
- t end
- s/.*/deleted/g
- : end
-
-`touch'
- On some old BSD systems, `touch' or any command that results in an
- empty file does not update the timestamps, so use a command like
- `echo' as a workaround.
-
- GNU `touch' 3.16r (and presumably all before that) fails to work
- on SunOS 4.1.3 when the empty file is on an NFS-mounted 4.2 volume.

-
-Specifying the System Type
-==========================
-
- Like other GNU `configure' scripts, Autoconf-generated `configure'
-scripts can make decisions based on a canonical name for the system
-type, which has the form: `CPU-VENDOR-OS', where OS can be `SYSTEM' or
-`KERNEL-SYSTEM'
-
- `configure' can usually guess the canonical name for the type of
-system it's running on. To do so it runs a script called
-`config.guess', which infers the name using the `uname' command or
-symbols predefined by the C preprocessor.
-
- Alternately, the user can specify the system type with command line
-arguments to `configure'. Doing so is necessary when cross-compiling.
-In the most complex case of cross-compiling, three system types are
-involved. The options to specify them are(1):
-
-`--build=BUILD-TYPE'
- the type of system on which the package is being configured and
- compiled.
-
-`--host=HOST-TYPE'
- the type of system on which the package will run.
-
-`--target=TARGET-TYPE'
- the type of system for which any compiler tools in the package will
- produce code (rarely needed). By default, it is the same as host.
-
- They all default to the result of running `config.guess', unless you
-specify either `--build' or `--host'. In this case, the default
-becomes the system type you specified. If you specify both, and
-they're different, `configure' will enter cross compilation mode, so it
-won't run any tests that require execution.
-
- Hint: if you mean to override the result of `config.guess', prefer
-`--build' over `--host'. In the future, `--host' will not override the
-name of the build system type. Also, if you specify `--host', but not
-`--build', when `configure' performs the first compiler test it will
-try to run an executable produced by the compiler. If the execution
-fails, it will enter cross-compilation mode. Note, however, that it
-won't guess the build-system type, since this may require running test
-programs. Moreover, by the time the compiler test is performed, it may
-be too late to modify the build-system type: other tests may have
-already been performed. Therefore, whenever you specify `--host', be
-sure to specify `--build' too.
-
- ./configure --build=i686-pc-linux-gnu --host=m68k-coff
-
-will enter cross-compilation mode, but `configure' will fail if it
-can't run the code generated by the specified compiler if you configure
-as follows:
-
- ./configure CC=m68k-coff-gcc
-
- `configure' recognizes short aliases for many system types; for
-example, `decstation' can be used instead of `mips-dec-ultrix4.2'.
-`configure' runs a script called `config.sub' to canonicalize system
-type aliases.
-
- ---------- Footnotes ----------
-
- (1) For backward compatibility, `configure' will accept a system
-type as an option by itself. Such an option will override the defaults
-for build, host and target system types. The following configure
-statement will configure a cross toolchain that will run on
-NetBSD/alpha but generate code for GNU Hurd/sparc, which is also the
-build platform.
-
- ./configure --host=alpha-netbsd sparc-gnu

-
-Getting the Canonical System Type
-=================================
-
- The following macros make the system type available to `configure'
-scripts.
-
- The variables `build_alias', `host_alias', and `target_alias' are
-always exactly the arguments of `--build', `--host', and `--target'; in
-particular, they are left empty if the user did not use them, even if
-the corresponding `AC_CANONICAL' macro was run. Any configure script
-may use these variables anywhere. These are the variables that should
-be used when in interaction with the user.
-
- If you need to recognize some special environments based on their
-system type, run the following macros to get canonical system names.
-These variables are not set before the macro call.
-
- If you use these macros, you must distribute `config.guess' and
-`config.sub' along with your source code. *Note Output::, for
-information about the `AC_CONFIG_AUX_DIR' macro which you can use to
-control in which directory `configure' looks for those scripts.
-
- - Macro: AC_CANONICAL_BUILD
- Compute the canonical build-system type variable, `build', and its
- three individual parts `build_cpu', `build_vendor', and `build_os'.
-
- If `--build' was specified, then `build' is the canonicalization
- of `build_alias' by `config.sub', otherwise it is determined by
- the shell script `config.guess'.
-
- - Macro: AC_CANONICAL_HOST
- Compute the canonical host-system type variable, `host', and its
- three individual parts `host_cpu', `host_vendor', and `host_os'.
-
- If `--host' was specified, then `host' is the canonicalization of
- `host_alias' by `config.sub', otherwise it defaults to `build'.
-
- For temporary backward-compatibility, when `--host' is specified
- by `--build' isn't, the build system will be assumed to be the
- same as `--host', and `build_alias' will be set to that value.
- Eventually, this historically incorrect behavior will go away.
-
-
- - Macro: AC_CANONICAL_TARGET
- Compute the canonical target-system type variable, `target', and
- its three individual parts `target_cpu', `target_vendor', and
- `target_os'.
-
- If `--target' was specified, then `target' is the canonicalization
- of `target_alias' by `config.sub', otherwise it defaults to `host'.

-
-Using the System Type
-=====================
-
- How do you use a canonical system type? Usually, you use it in one
-or more `case' statements in `configure.ac' to select system-specific C
-files. Then, using `AC_CONFIG_LINKS', link those files which have
-names based on the system name, to generic names, such as `host.h' or
-`target.c' (*note Configuration Links::). The `case' statement
-patterns can use shell wild cards to group several cases together, like

-Site Configuration
-******************
-
- `configure' scripts support several kinds of local configuration
-decisions. There are ways for users to specify where external software
-packages are, include or exclude optional features, install programs
-under modified names, and set default values for `configure' options.

-
-Working With External Software
-==============================
-
- Some packages require, or can optionally use, other software packages
-that are already installed. The user can give `configure' command line
-options to specify which such external software to use. The options
-have one of these forms:
-
- --with-PACKAGE=[ARG]
- --without-PACKAGE
-
- For example, `--with-gnu-ld' means work with the GNU linker instead
-of some other linker. `--with-x' means work with The X Window System.
-
- The user can give an argument by following the package name with `='
-and the argument. Giving an argument of `no' is for packages that are
-used by default; it says to _not_ use the package. An argument that is
-neither `yes' nor `no' could include a name or number of a version of
-the other package, to specify more precisely which other package this
-program is supposed to work with. If no argument is given, it defaults
-to `yes'. `--without-PACKAGE' is equivalent to `--with-PACKAGE=no'.
-
- `configure' scripts do not complain about `--with-PACKAGE' options
-that they do not support. This behavior permits configuring a source
-tree containing multiple packages with a top-level `configure' script
-when the packages support different options, without spurious error
-messages about options that some of the packages support. An
-unfortunate side effect is that option spelling errors are not
-diagnosed. No better approach to this problem has been suggested so
-far.
-
- For each external software package that may be used, `configure.ac'
-should call `AC_ARG_WITH' to detect whether the `configure' user asked
-to use it. Whether each package is used or not by default, and which
-arguments are valid, is up to you.
-
- - Macro: AC_ARG_WITH (PACKAGE, HELP-STRING, [ACTION-IF-GIVEN],
- [ACTION-IF-NOT-GIVEN])
- If the user gave `configure' the option `--with-PACKAGE' or
- `--without-PACKAGE', run shell commands ACTION-IF-GIVEN. If
- neither option was given, run shell commands ACTION-IF-NOT-GIVEN.
- The name PACKAGE indicates another software package that this
- program should work with. It should consist only of alphanumeric
- characters and dashes.
-
- The option's argument is available to the shell commands
- ACTION-IF-GIVEN in the shell variable `withval', which is actually
- just the value of the shell variable `with_PACKAGE', with any `-'
- characters changed into `_'. You may use that variable instead,
- if you wish.
-
- The argument HELP-STRING is a description of the option that looks
- like this:
- --with-readline support fancy command line editing
-
- HELP-STRING may be more than one line long, if more detail is
- needed. Just make sure the columns line up in `configure --help'.
- Avoid tabs in the help string. You'll need to enclose it in `['
- and `]' in order to produce the leading spaces.
-
- You should format your HELP-STRING with the macro `AC_HELP_STRING'
- (*note Pretty Help Strings::).
-
- - Macro: AC_WITH (PACKAGE, ACTION-IF-GIVEN, [ACTION-IF-NOT-GIVEN])
- This is an obsolete version of `AC_ARG_WITH' that does not support
- providing a help string.

-
-Choosing Package Options
-========================
-
- If a software package has optional compile-time features, the user
-can give `configure' command line options to specify whether to compile
-them. The options have one of these forms:
-
- --enable-FEATURE=[ARG]
- --disable-FEATURE
-
- These options allow users to choose which optional features to build
-and install. `--enable-FEATURE' options should never make a feature
-behave differently or cause one feature to replace another. They
-should only cause parts of the program to be built rather than left out.
-
- The user can give an argument by following the feature name with `='
-and the argument. Giving an argument of `no' requests that the feature
-_not_ be made available. A feature with an argument looks like
-`--enable-debug=stabs'. If no argument is given, it defaults to `yes'.
-`--disable-FEATURE' is equivalent to `--enable-FEATURE=no'.
-
- `configure' scripts do not complain about `--enable-FEATURE' options
-that they do not support. This behavior permits configuring a source
-tree containing multiple packages with a top-level `configure' script
-when the packages support different options, without spurious error
-messages about options that some of the packages support. An
-unfortunate side effect is that option spelling errors are not
-diagnosed. No better approach to this problem has been suggested so
-far.
-
- For each optional feature, `configure.ac' should call
-`AC_ARG_ENABLE' to detect whether the `configure' user asked to include
-it. Whether each feature is included or not by default, and which
-arguments are valid, is up to you.
-
- - Macro: AC_ARG_ENABLE (FEATURE, HELP-STRING, [ACTION-IF-GIVEN],
- [ACTION-IF-NOT-GIVEN])
- If the user gave `configure' the option `--enable-FEATURE' or
- `--disable-FEATURE', run shell commands ACTION-IF-GIVEN. If
- neither option was given, run shell commands ACTION-IF-NOT-GIVEN.
- The name FEATURE indicates an optional user-level facility. It
- should consist only of alphanumeric characters and dashes.
-
- The option's argument is available to the shell commands
- ACTION-IF-GIVEN in the shell variable `enableval', which is
- actually just the value of the shell variable `enable_FEATURE',
- with any `-' characters changed into `_'. You may use that
- variable instead, if you wish. The HELP-STRING argument is like
- that of `AC_ARG_WITH' (*note External Software::).
-
- You should format your HELP-STRING with the macro `AC_HELP_STRING'
- (*note Pretty Help Strings::).
-
- - Macro: AC_ENABLE (FEATURE, ACTION-IF-GIVEN, [ACTION-IF-NOT-GIVEN])
- This is an obsolete version of `AC_ARG_ENABLE' that does not
- support providing a help string.
-

-
-Making Your Help Strings Look Pretty
-====================================
-
- Properly formatting the `help strings' which are used in
-`AC_ARG_WITH' (*note External Software::) and `AC_ARG_ENABLE' (*note
-Package Options::) can be challenging. Specifically, you want your own
-`help strings' to line up in the appropriate columns of `configure
---help' just like the standard Autoconf `help strings' do. This is the
-purpose of the `AC_HELP_STRING' macro.
-
- - Macro: AC_HELP_STRING (LEFT-HAND-SIDE, RIGHT-HAND-SIDE)
- Expands into an help string that looks pretty when the user
- executes `configure --help'. It is typically used in `AC_ARG_WITH'
- (*note External Software::) or `AC_ARG_ENABLE' (*note Package
- Options::). The following example will make this clearer.
-
- AC_DEFUN(TEST_MACRO,
- [AC_ARG_WITH(foo,
- AC_HELP_STRING([--with-foo],
- [use foo (default is NO)]),
- ac_cv_use_foo=$withval, ac_cv_use_foo=no),
- AC_CACHE_CHECK(whether to use foo,
- ac_cv_use_foo, ac_cv_use_foo=no)])
-
- Please note that the call to `AC_HELP_STRING' is *unquoted*. Then
- the last few lines of `configure --help' will appear like this:
-
- --enable and --with options recognized:
- --with-foo use foo (default is NO)
-
- The `AC_HELP_STRING' macro is particularly helpful when the
- LEFT-HAND-SIDE and/or RIGHT-HAND-SIDE are composed of macro
- arguments, as shown in the following example.
-
- AC_DEFUN(MY_ARG_WITH,
- [AC_ARG_WITH([$1],
- AC_HELP_STRING([--with-$1], [use $1 (default is $2)]),
- ac_cv_use_$1=$withval, ac_cv_use_$1=no),
- AC_CACHE_CHECK(whether to use $1, ac_cv_use_$1, ac_cv_use_$1=$2)])

-
-Configuring Site Details
-========================
-
- Some software packages require complex site-specific information.
-Some examples are host names to use for certain services, company
-names, and email addresses to contact. Since some configuration
-scripts generated by Metaconfig ask for such information interactively,
-people sometimes wonder how to get that information in
-Autoconf-generated configuration scripts, which aren't interactive.
-
- Such site configuration information should be put in a file that is
-edited _only by users_, not by programs. The location of the file can
-either be based on the `prefix' variable, or be a standard location
-such as the user's home directory. It could even be specified by an
-environment variable. The programs should examine that file at run
-time, rather than at compile time. Run time configuration is more
-convenient for users and makes the configuration process simpler than
-getting the information while configuring. *Note Variables for
-Installation Directories: (standards)Directory Variables, for more
-information on where to put data files.

-
-Transforming Program Names When Installing
-==========================================
-
- Autoconf supports changing the names of programs when installing
-them. In order to use these transformations, `configure.ac' must call
-the macro `AC_ARG_PROGRAM'.
-
- - Macro: AC_ARG_PROGRAM
- Place in output variable `program_transform_name' a sequence of
- `sed' commands for changing the names of installed programs.
-
- If any of the options described below are given to `configure',
- program names are transformed accordingly. Otherwise, if
- `AC_CANONICAL_TARGET' has been called and a `--target' value is
- given that differs from the host type (specified with `--host'),
- the target type followed by a dash is used as a prefix.
- Otherwise, no program name transformation is done.
-
-* Menu:
-
-* Transformation Options:: `configure' options to transform names
-* Transformation Examples:: Sample uses of transforming names
-* Transformation Rules:: `Makefile' uses of transforming names
-
-
-File: autoconf.info, Node: Transformation Options, Next: Transformation Examples, Prev: Transforming Names, Up: Transforming Names
-
-Transformation Options
-----------------------
-
- You can specify name transformations by giving `configure' these
-command line options:
-
-`--program-prefix=PREFIX'
- prepend PREFIX to the names;
-
-`--program-suffix=SUFFIX'
- append SUFFIX to the names;
-
-`--program-transform-name=EXPRESSION'
- perform `sed' substitution EXPRESSION on the names.
-
-
-File: autoconf.info, Node: Transformation Examples, Next: Transformation Rules, Prev: Transformation Options, Up: Transforming Names
-
-Transformation Examples
------------------------
-
- These transformations are useful with programs that can be part of a
-cross-compilation development environment. For example, a
-cross-assembler running on a Sun 4 configured with
-`--target=i960-vxworks' is normally installed as `i960-vxworks-as',
-rather than `as', which could be confused with a native Sun 4 assembler.
-
- You can force a program name to begin with `g', if you don't want
-GNU programs installed on your system to shadow other programs with the
-same name. For example, if you configure GNU `diff' with
-`--program-prefix=g', then when you run `make install' it is installed
-as `/usr/local/bin/gdiff'.
-
- As a more sophisticated example, you could use
-
- --program-transform-name='s/^/g/; s/^gg/g/; s/^gless/less/'
-
-to prepend `g' to most of the program names in a source tree, excepting
-those like `gdb' that already have one and those like `less' and
-`lesskey' that aren't GNU programs. (That is assuming that you have a
-source tree containing those programs that is set up to use this
-feature.)
-
- One way to install multiple versions of some programs simultaneously
-is to append a version number to the name of one or both. For example,
-if you want to keep Autoconf version 1 around for awhile, you can
-configure Autoconf version 2 using `--program-suffix=2' to install the
-programs as `/usr/local/bin/autoconf2', `/usr/local/bin/autoheader2',
-etc. Nevertheless, pay attention that only the binaries are renamed,
-therefore you'd have problems with the library files which might
-overlap.
-
-
-File: autoconf.info, Node: Transformation Rules, Prev: Transformation Examples, Up: Transforming Names
-
-Transformation Rules
---------------------
-
- Here is how to use the variable `program_transform_name' in a
-`Makefile.in':
-
- transform = @program_transform_name@
- install: all
- $(INSTALL_PROGRAM) myprog $(bindir)/`echo myprog | \
- sed '$(transform)'`
-
- uninstall:
- rm -f $(bindir)/`echo myprog | sed '$(transform)'`
-
-If you have more than one program to install, you can do it in a loop:
-
- PROGRAMS = cp ls rm
- install:
- for p in $(PROGRAMS); do \
- $(INSTALL_PROGRAM) $$p $(bindir)/`echo $$p | \
- sed '$(transform)'`; \
- done
-
- uninstall:
- for p in $(PROGRAMS); do \
- rm -f $(bindir)/`echo $$p | sed '$(transform)'`; \
- done
-
- It is guaranteed that `program_transform_name' is never empty, and
-that there are no useless separators. Therefore you may safely embed
-`program_transform_name' within a sed program using `;':
-
- transform = @program_transform_name@
- transform_exe = s/$(EXEEXT)$$//;$(transform);s/$$/$(EXEEXT)/
-
- Whether to do the transformations on documentation files (Texinfo or
-`man') is a tricky question; there seems to be no perfect answer, due
-to the several reasons for name transforming. Documentation is not
-usually particular to a specific architecture, and Texinfo files do not
-conflict with system documentation. But they might conflict with
-earlier versions of the same files, and `man' pages sometimes do
-conflict with system documentation. As a compromise, it is probably
-best to do name transformations on `man' pages but not on Texinfo
-manuals.

-
-Setting Site Defaults
-=====================
-
- Autoconf-generated `configure' scripts allow your site to provide
-default values for some configuration values. You do this by creating
-site- and system-wide initialization files.
-
- If the environment variable `CONFIG_SITE' is set, `configure' uses
-its value as the name of a shell script to read. Otherwise, it reads
-the shell script `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists. Thus, settings in
-machine-specific files override those in machine-independent ones in
-case of conflict.
-
- Site files can be arbitrary shell scripts, but only certain kinds of
-code are really appropriate to be in them. Because `configure' reads
-any cache file after it has read any site files, a site file can define
-a default cache file to be shared between all Autoconf-generated
-`configure' scripts run on that system (*note Cache Files::). If you
-set a default cache file in a site file, it is a good idea to also set
-the output variable `CC' in that site file, because the cache file is
-only valid for a particular compiler, but many systems have several
-available.
-
- You can examine or override the value set by a command line option to
-`configure' in a site file; options set shell variables that have the
-same names as the options, with any dashes turned into underscores.
-The exceptions are that `--without-' and `--disable-' options are like
-giving the corresponding `--with-' or `--enable-' option and the value
-`no'. Thus, `--cache-file=localcache' sets the variable `cache_file'
-to the value `localcache'; `--enable-warnings=no' or
-`--disable-warnings' sets the variable `enable_warnings' to the value
-`no'; `--prefix=/usr' sets the variable `prefix' to the value `/usr';
-etc.
-
- Site files are also good places to set default values for other
-output variables, such as `CFLAGS', if you need to give them non-default
-values: anything you would normally do, repetitively, on the command
-line. If you use non-default values for PREFIX or EXEC_PREFIX
-(wherever you locate the site file), you can set them in the site file
-if you specify it with the `CONFIG_SITE' environment variable.
-
- You can set some cache values in the site file itself. Doing this is
-useful if you are cross-compiling, so it is impossible to check features
-that require running a test program. You could "prime the cache" by
-setting those values correctly for that system in
-`PREFIX/etc/config.site'. To find out the names of the cache variables
-you need to set, look for shell variables with `_cv_' in their names in
-the affected `configure' scripts, or in the Autoconf M4 source code for
-those macros.
-
- The cache file is careful to not override any variables set in the
-site files. Similarly, you should not override command-line options in
-the site files. Your code should check that variables such as `prefix'
-and `cache_file' have their default values (as set near the top of
-`configure') before changing them.
-
- Here is a sample file `/usr/share/local/gnu/share/config.site'. The
-command `configure --prefix=/usr/share/local/gnu' would read this file
-(if `CONFIG_SITE' is not set to a different file).
-
- # config.site for configure
- #
- # Change some defaults.
- test "$prefix" = NONE && prefix=/usr/share/local/gnu
- test "$exec_prefix" = NONE && exec_prefix=/usr/local/gnu
- test "$sharedstatedir" = '$prefix/com' && sharedstatedir=/var
- test "$localstatedir" = '$prefix/var' && localstatedir=/var
-
- # Give Autoconf 2.x generated configure scripts a shared default
- # cache file for feature test results, architecture-specific.
- if test "$cache_file" = /dev/null; then
- cache_file="$prefix/var/config.cache"
- # A cache file is only valid for one C compiler.

-Running `configure' Scripts
-***************************
-
- Below are instructions on how to configure a package that uses a
-`configure' script, suitable for inclusion as an `INSTALL' file in the

-with Autoconf.

-File: autoconf.info, Node: Basic Installation, Next: Compilers and Options, Up: Running configure scripts
-
-Basic Installation
-==================
-
- These are generic installation instructions.
-
- The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation. It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions. Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
- It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring. (Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.)
-
- If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release. If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
- The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'. You only need
-`configure.ac' if you want to change it or regenerate `configure' using
-a newer version of `autoconf'.
-
-The simplest way to compile this package is:
-
- 1. `cd' to the directory containing the package's source code and type
- `./configure' to configure the package for your system. If you're
- using `csh' on an old version of System V, you might need to type
- `sh ./configure' instead to prevent `csh' from trying to execute
- `configure' itself.
-
- Running `configure' takes awhile. While running, it prints some
- messages telling which features it is checking for.
-
- 2. Type `make' to compile the package.
-
- 3. Optionally, type `make check' to run any self-tests that come with
- the package.
-
- 4. Type `make install' to install the programs and any data files and
- documentation.
-
- 5. You can remove the program binaries and object files from the
- source code directory by typing `make clean'. To also remove the
- files that `configure' created (so you can compile the package for
- a different kind of computer), type `make distclean'. There is
- also a `make maintainer-clean' target, but that is intended mainly
- for the package's developers. If you use it, you may have to get
- all sorts of other programs in order to regenerate files that came
- with the distribution.

-
-Compilers and Options
-=====================
-
- Some systems require unusual options for compilation or linking that
-the `configure' script does not know about. Run `./configure --help'
-for details on some of the pertinent environment variables.
-
- You can give `configure' initial values for variables by setting
-them in the environment. You can do that on the command line like this:
-
- ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
-
- *Note Environment Variables::, for more details.
-
-
-File: autoconf.info, Node: Multiple Architectures, Next: Installation Names, Prev: Compilers and Options, Up: Running configure scripts
-
-Compiling For Multiple Architectures
-====================================
-
- You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory. To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'. `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script. `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
- If you have to use a `make' that does not support the `VPATH'
-variable, you have to compile the package for one architecture at a time
-in the source code directory. After you have installed the package for
-one architecture, use `make distclean' before reconfiguring for another
-architecture.
-
-
-File: autoconf.info, Node: Installation Names, Next: Optional Features, Prev: Multiple Architectures, Up: Running configure scripts
-
-Installation Names
-==================
-
- By default, `make install' will install the package's files in
-`/usr/local/bin', `/usr/local/man', etc. You can specify an
-installation prefix other than `/usr/local' by giving `configure' the
-option `--prefix=PATH'.
-
- You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files. If you
-give `configure' the option `--exec-prefix=PATH', the package will use
-PATH as the prefix for installing programs and libraries.
-Documentation and other data files will still use the regular prefix.
-
- In addition, if you use an unusual directory layout you can give
-options like `--bindir=PATH' to specify different values for particular
-kinds of files. Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
- If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.

-
-Optional Features
-=================
-
- Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System). The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
- For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-
-File: autoconf.info, Node: System Type, Next: Sharing Defaults, Prev: Optional Features, Up: Running configure scripts
-
-Specifying the System Type
-==========================
-
- There may be some features `configure' cannot figure out
-automatically, but needs to determine by the type of host the package
-will run on. Usually `configure' can figure that out, but if it prints
-a message saying it cannot guess the host type, give it the
-`--build=TYPE' option. TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
- CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
- OS
- KERNEL-OS
-
- See the file `config.sub' for the possible values of each field. If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the host type.
-
- If you are _building_ compiler tools for cross-compiling, you should
-use the `--target=TYPE' option to select the type of system they will
-produce code for.
-
- If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the host
-platform (i.e., that on which the generated programs will eventually be
-run) with `--host=TYPE'. In this case, you should also specify the
-build platform with `--build=TYPE', because, in this case, it may not
-be possible to guess the build platform (it sometimes involves
-compiling and running simple test programs, and this can't be done if
-the compiler is a cross compiler).
-
-
-File: autoconf.info, Node: Sharing Defaults, Next: Environment Variables, Prev: System Type, Up: Running configure scripts
-
-Sharing Defaults
-================
-
- If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists. Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.

-Environment Variables
-=====================
-
- Variables not defined in a site shell script can be set in the
-environment passed to configure. However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost. In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'. For example:
-
- ./configure CC=/usr/local2/bin/gcc
-
-will cause the specified gcc to be used as the C compiler (unless it is
-overridden in the site shell script).

-
-`configure' Invocation
-======================
-
- `configure' recognizes the following options to control how it
-operates.
-
-`--help'
-`-h'
- Print a summary of the options to `configure', and exit.
-
-`--version'
-`-V'
- Print the version of Autoconf used to generate the `configure'
- script, and exit.
-
-`--cache-file=FILE'
- Enable the cache: use and save the results of the tests in FILE,
- traditionally `config.cache'. FILE defaults to `/dev/null' to
- disable caching.
-
-`--config-cache'
-`-C'
- Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
- Do not print messages saying which checks are being made. To
- suppress all normal output, redirect it to `/dev/null' (any error
- messages will still be shown).
-
-`--srcdir=DIR'
- Look for the package's source code in directory DIR. Usually
- `configure' can determine that directory automatically.
-
-`configure' also accepts some other, not widely useful, options. Run
-`configure --help' for more details.

-
-Recreating a Configuration
-**************************
-
- The `configure' script creates a file named `config.status', which
-actually configures, "instantiates", the template files. It also
-records the configuration options that were specified when the package
-was last configured in case reconfiguring is needed.
-
- Synopsis:
- ./config.status OPTION... [FILE...]
-
- It configures the FILES, if none are specified, all the templates
-are instantiated. The files must be specified without their
-dependencies, as in
-
- ./config.status foobar
-
-not
-
- ./config.status foobar:foo.in:bar.in
-
- The supported OPTIONs are:
-
-`--help'
-`-h'
- Print a summary of the command line options, the list of the
- template files and exit.
-
-`--version'
-`-V'
- Print the version number of Autoconf and exit.
-
-`--debug'
-`-d'
- Don't remove the temporary files.
-
-`--file=FILE[:TEMPLATE]'
- Require that FILE be instantiated as if
- `AC_CONFIG_FILES(FILE:TEMPLATE)' was used. Both FILE and TEMPLATE
- may be `-' in which case the standard output and/or standard
- input, respectively, is used. If a TEMPLATE filename is relative,
- it is first looked for in the build tree, and then in the source
- tree. *Note Configuration Actions::, for more details.
-
- This option and the following ones provide one way for separately
- distributed packages to share the values computed by `configure'.
- Doing so can be useful if some of the packages need a superset of
- the features that one of them, perhaps a common library, does.
- These options allow a `config.status' file to create files other
- than the ones that its `configure.ac' specifies, so it can be used
- for a different package.
-
-`--header=FILE[:TEMPLATE]'
- Same as `--file' above, but with `AC_CONFIG_HEADERS'.
-
-`--recheck'
- Ask `config.status' to update itself and exit (no instantiation).
- This option is useful if you change `configure', so that the
- results of some tests might be different from the previous run.
- The `--recheck' option re-runs `configure' with the same arguments
- you used before, plus the `--no-create' option, which prevents
- `configure' from running `config.status' and creating `Makefile'
- and other files, and the `--no-recursion' option, which prevents
- `configure' from running other `configure' scripts in
- subdirectories. (This is so other `Makefile' rules can run
- `config.status' when it changes; *note Automatic Remaking::, for
- an example).
-
- `config.status' checks several optional environment variables that
-can alter its behavior:
-
- - Variable: CONFIG_SHELL
- The shell with which to run `configure' for the `--recheck'
- option. It must be Bourne-compatible. The default is `/bin/sh'.
-
- - Variable: CONFIG_STATUS
- The file name to use for the shell script that records the
- configuration. The default is `./config.status'. This variable is
- useful when one package uses parts of another and the `configure'
- scripts shouldn't be merged because they are maintained separately.
-
- You can use `./config.status' in your Makefiles. For example, in
-the dependencies given above (*note Automatic Remaking::),
-`config.status' is run twice when `configure.ac' has changed. If that
-bothers you, you can make each run only regenerate the files for that
-rule:
- config.h: stamp-h
- stamp-h: config.h.in config.status
- ./config.status config.h
- echo > stamp-h
-
- Makefile: Makefile.in config.status
- ./config.status Makefile
-
- The calling convention of `config.status' has changed, see *Note
-Obsolete config.status Use::, for details.

-Obsolete Constructs
-*******************
-
- Autoconf changes, and throughout the years some constructs are
-obsoleted. Most of the changes involve the macros, but the tools
-themselves, or even some concepts, are now considered obsolete.
-
- You may completely skip this chapter if you are new to Autoconf, its
-intention is mainly to help maintainers updating their packages by
-understanding how to move to more modern constructs.

-Obsolete `config.status' Invocation
-===================================
-
- `config.status' now supports arguments to specify the files to
-instantiate, see *Note config.status Invocation::, for more details.
-Before, environment variables had to be used.
-
- - Variable: CONFIG_COMMANDS
- The tags of the commands to execute. The default is the arguments
- given to `AC_OUTPUT' and `AC_CONFIG_COMMANDS' in `configure.ac'.
-
- - Variable: CONFIG_FILES
- The files in which to perform `@VARIABLE@' substitutions. The
- default is the arguments given to `AC_OUTPUT' and
- `AC_CONFIG_FILES' in `configure.ac'.
-
- - Variable: CONFIG_HEADERS
- The files in which to substitute C `#define' statements. The
- default is the arguments given to `AC_CONFIG_HEADERS'; if that
- macro was not called, `config.status' ignores this variable.
-
- - Variable: CONFIG_LINKS
- The symbolic links to establish. The default is the arguments
- given to `AC_CONFIG_LINKS'; if that macro was not called,
- `config.status' ignores this variable.
-
- In *Note config.status Invocation::, using this old interface, the
-example would be:
-
- config.h: stamp-h
- stamp-h: config.h.in config.status
- CONFIG_COMMANDS= CONFIG_LINKS= CONFIG_FILES= \
- CONFIG_HEADERS=config.h ./config.status
- echo > stamp-h
-
- Makefile: Makefile.in config.status
- CONFIG_COMMANDS= CONFIG_LINKS= CONFIG_HEADERS= \
- CONFIG_FILES=Makefile ./config.status
-
-(If `configure.ac' does not call `AC_CONFIG_HEADERS', there is no need
-to set `CONFIG_HEADERS' in the `make' rules, equally for
-`CONFIG_COMMANDS' etc.)
-
-
-File: autoconf.info, Node: acconfig.h, Next: autoupdate Invocation, Prev: Obsolete config.status Use, Up: Obsolete Constructs
-
-`acconfig.h'
-============
-
- In order to produce `config.h.in', `autoheader' needs to build or to
-find templates for each symbol. Modern releases of Autoconf use
-`AH_VERBATIM' and `AH_TEMPLATE' (*note Autoheader Macros::), but in
-older releases a file, `acconfig.h', contained the list of needed
-templates. `autoheader' copies comments and `#define' and `#undef'
-statements from `acconfig.h' in the current directory, if present.
-This file used to be mandatory if you `AC_DEFINE' any additional
-symbols.
-
- Modern releases of Autoconf also provide `AH_TOP' and `AH_BOTTOM' if
-you need to prepend/append some information to `config.h.in'. Ancient
-versions of Autoconf had a similar feature: if `./acconfig.h' contains
-the string `@TOP@', `autoheader' copies the lines before the line
-containing `@TOP@' into the top of the file that it generates.
-Similarly, if `./acconfig.h' contains the string `@BOTTOM@',
-`autoheader' copies the lines after that line to the end of the file it
-generates. Either or both of those strings may be omitted. An even
-older alternate way to produce the same effect in jurasik versions of
-Autoconf is to create the files `FILE.top' (typically `config.h.top')
-and/or `FILE.bot' in the current directory. If they exist,
-`autoheader' copies them to the beginning and end, respectively, of its
-output.
-
- In former versions of Autoconf, the files used in preparing a
-software package for distribution were:
- configure.ac --. .------> autoconf* -----> configure
- +---+
- [aclocal.m4] --+ `---.
- [acsite.m4] ---' |
- +--> [autoheader*] -> [config.h.in]
- [acconfig.h] ----. |
- +-----'
- [config.h.top] --+
- [config.h.bot] --'
-
- Use only the `AH_' macros, `configure.ac' should be self-contained,
-and should not depend upon `acconfig.h' etc.
-
-
-File: autoconf.info, Node: autoupdate Invocation, Next: Obsolete Macros, Prev: acconfig.h, Up: Obsolete Constructs
-
-Using `autoupdate' to Modernize `configure.ac'
-==============================================
-
- The `autoupdate' program updates a `configure.ac' file that calls
-Autoconf macros by their old names to use the current macro names. In
-version 2 of Autoconf, most of the macros were renamed to use a more
-uniform and descriptive naming scheme. *Note Macro Names::, for a
-description of the new scheme. Although the old names still work
-(*note Obsolete Macros::, for a list of the old macros and the
-corresponding new names), you can make your `configure.ac' files more
-readable and make it easier to use the current Autoconf documentation
-if you update them to use the new macro names.
-
- If given no arguments, `autoupdate' updates `configure.ac', backing
-up the original version with the suffix `~' (or the value of the
-environment variable `SIMPLE_BACKUP_SUFFIX', if that is set). If you
-give `autoupdate' an argument, it reads that file instead of
-`configure.ac' and writes the updated file to the standard output.
-
-`autoupdate' accepts the following options:
-
-`--help'
-`-h'
- Print a summary of the command line options and exit.
-
-`--version'
-`-V'
- Print the version number of Autoconf and exit.
-
-`--verbose'
-`-v'
- Report processing steps.
-
-`--debug'
-`-d'
- Don't remove the temporary files.
-
-`--autoconf-dir=DIR'
-`-A DIR'
- Override the location where the installed Autoconf data files are
- looked for. You can also set the `AC_MACRODIR' environment
- variable to a directory; this option overrides the environment
- variable.
-
- This option is rarely needed and dangerous; it is only used when
- one plays with different versions of Autoconf simultaneously.
-
-`--localdir=DIR'
-`-l DIR'
- Look for the package file `aclocal.m4' in directory DIR instead of
- in the current directory.
-

-File: autoconf.info, Node: Obsolete Macros, Next: Autoconf 1, Prev: autoupdate Invocation, Up: Obsolete Constructs
-
-Obsolete Macros
-===============
-
- Several macros are obsoleted in Autoconf, for various reasons
-(typically they failed to quote properly, couldn't be extended for more
-recent issues etc.). They are still supported, but deprecated: their
-use should be avoided.
-
- During the jump from Autoconf version 1 to version 2, most of the
-macros were renamed to use a more uniform and descriptive naming scheme,
-but their signature did not change. *Note Macro Names::, for a
-description of the new naming scheme. Below, there is just the mapping
-from old names to new names for these macros, the reader is invited to
-refer to the definition of the new macro for the signature and the
-description.
-
- - Macro: AC_ALLOCA
- `AC_FUNC_ALLOCA'
-
- - Macro: AC_ARG_ARRAY
- removed because of limited usefulness
-
- - Macro: AC_C_CROSS
- This macro is obsolete; it does nothing.
-
- - Macro: AC_CANONICAL_SYSTEM
- Determine the system type and set output variables to the names of
- the canonical system types. *Note Canonicalizing::, for details
- about the variables this macro sets.
-
- The user is encouraged to use either `AC_CANONICAL_BUILD', or
- `AC_CANONICAL_HOST', or `AC_CANONICAL_TARGET', depending on the
- needs. Using `AC_CANONICAL_TARGET' is enough to run the two other
- macros.
-
- - Macro: AC_CHAR_UNSIGNED
- `AC_C_CHAR_UNSIGNED'
-
- - Macro: AC_CHECK_TYPE (TYPE, DEFAULT)
- Autoconf, up to 2.13, used to provide this version of
- `AC_CHECK_TYPE', deprecated because of its flaws. Firstly,
- although it is a member of the `CHECK' clan, singular sub-family,
- it does more than just checking. Second, missing types are not
- `typedef''d, they are `#define''d, which can lead to incompatible
- code in the case of pointer types.
-
- This use of `AC_CHECK_TYPE' is obsolete and discouraged, see *Note
- Generic Types::, for the description of the current macro.
-
- If the type TYPE is not defined, define it to be the C (or C++)
- builtin type DEFAULT; e.g., `short' or `unsigned'.
-
- This macro is equivalent to:
-
- AC_CHECK_TYPE([TYPE],
- [AC_DEFINE([TYPE], [DEFAULT],
- [Define to `DEFAULT' if <sys/types.h>
- does not define.])])
-
- In order to keep backward compatibility, the two versions of
- `AC_CHECK_TYPE' are implemented, selected by a simple heuristics:
-
- 1. If there are three or four arguments, the modern version is
- used.
-
- 2. If the second argument appears to be a C or C++ type, then the
- obsolete version is used. This happens if the argument is a
- C or C++ _builtin_ type or a C identifier ending in `_t',
- optionally followed by one of `[(* ' and then by a string of
- zero or more characters taken from the set `[]()* _a-zA-Z0-9'.
-
- 3. If the second argument is spelled with the alphabet of valid
- C and C++ types, the user is warned and the modern version is
- used.
-
- 4. Otherwise, the modern version is used.
-
- You are encouraged either to use a valid builtin type, or to use
- the equivalent modern code (see above), or better yet, to use
- `AC_CHECK_TYPES' together with
-
- #if !HAVE_LOFF_T
- typedef loff_t off_t;
- #endif
-
- - Macro: AC_CHECKING (FEATURE-DESCRIPTION)
- Same as `AC_MSG_NOTICE([checking FEATURE-DESCRIPTION...]'.
-
- - Macro: AC_COMPILE_CHECK (ECHO-TEXT, INCLUDES, FUNCTION-BODY,
- ACTION-IF-FOUND, [ACTION-IF-NOT-FOUND])
- This is an obsolete version of `AC_TRY_LINK' (*note Examining
- Libraries::), with the addition that it prints `checking for
- ECHO-TEXT' to the standard output first, if ECHO-TEXT is
- non-empty. Use `AC_MSG_CHECKING' and `AC_MSG_RESULT' instead to
- print messages (*note Printing Messages::).
-
- - Macro: AC_CONST
- `AC_C_CONST'
-
- - Macro: AC_CROSS_CHECK
- Same as `AC_C_CROSS', which is obsolete too, and does nothing
- `:-)'.
-
- - Macro: AC_CYGWIN
- Check for the Cygwin environment in which case the shell variable
- `CYGWIN' is set to `yes'. Don't use this macro, the dignified
- means to check the nature of the host is using
- `AC_CANONICAL_HOST'. As a matter of fact this macro is defined as:
-
- AC_REQUIRE([AC_CANONICAL_HOST])[]dnl
- case $host_os in
- *cygwin* ) CYGWIN=yes;;
- * ) CYGWIN=no;;
- esac
-
- Beware that the variable `CYGWIN' has a very special meaning when
- running CygWin32, and should not be changed. That's yet another
- reason not to use this macro.
-
- - Macro: AC_DECL_YYTEXT
- Does nothing, now integrated in `AC_PROG_LEX'.
-
- - Macro: AC_DIR_HEADER
- Like calling `AC_FUNC_CLOSEDIR_VOID' and`AC_HEADER_DIRENT', but
- defines a different set of C preprocessor macros to indicate which
- header file is found:
-
- Header Old Symbol New Symbol
- `dirent.h' `DIRENT' `HAVE_DIRENT_H'
- `sys/ndir.h' `SYSNDIR' `HAVE_SYS_NDIR_H'
- `sys/dir.h' `SYSDIR' `HAVE_SYS_DIR_H'
- `ndir.h' `NDIR' `HAVE_NDIR_H'
-
- - Macro: AC_DYNIX_SEQ
- If on Dynix/PTX (Sequent UNIX), add `-lseq' to output variable
- `LIBS'. This macro used to be defined as
-
- AC_CHECK_LIB(seq, getmntent, LIBS="-lseq $LIBS")
-
- now it is just `AC_FUNC_GETMNTENT'.
-
- - Macro: AC_EXEEXT
- Defined the output variable `EXEEXT' based on the output of the
- compiler, which is now done automatically. Typically set to empty
- string if Unix and `.exe' if Win32 or OS/2.
-
- - Macro: AC_EMXOS2
- Similar to `AC_CYGWIN' but checks for the EMX environment on OS/2
- and sets `EMXOS2'.
-
- - Macro: AC_ERROR
- `AC_MSG_ERROR'
-
- - Macro: AC_FIND_X
- `AC_PATH_X'
-
- - Macro: AC_FIND_XTRA
- `AC_PATH_XTRA'
-
- - Macro: AC_FUNC_CHECK
- `AC_CHECK_FUNC'
-
- - Macro: AC_FUNC_WAIT3
- If `wait3' is found and fills in the contents of its third argument
- (a `struct rusage *'), which HP-UX does not do, define
- `HAVE_WAIT3'.
-
- These days portable programs should use `waitpid', not `wait3', as
- `wait3' is being removed from the Open Group standards, and will
- not appear in the next revision of POSIX.
-
- - Macro: AC_GCC_TRADITIONAL
- `AC_PROG_GCC_TRADITIONAL'
-
- - Macro: AC_GETGROUPS_T
- `AC_TYPE_GETGROUPS'
-
- - Macro: AC_GETLOADAVG
- `AC_FUNC_GETLOADAVG'
-
- - Macro: AC_HAVE_FUNCS
- `AC_CHECK_FUNCS'
-
- - Macro: AC_HAVE_HEADERS
- `AC_CHECK_HEADERS'
-
- - Macro: AC_HAVE_LIBRARY (LIBRARY, [ACTION-IF-FOUND],
- [ACTION-IF-NOT-FOUND], [OTHER-LIBRARIES])
- This macro is equivalent to calling `AC_CHECK_LIB' with a FUNCTION
- argument of `main'. In addition, LIBRARY can be written as any of
- `foo', `-lfoo', or `libfoo.a'. In all of those cases, the
- compiler is passed `-lfoo'. However, LIBRARY cannot be a shell
- variable; it must be a literal name.
-
- - Macro: AC_HAVE_POUNDBANG
- `AC_SYS_INTERPRETER' (different calling convention)
-
- - Macro: AC_HEADER_CHECK
- `AC_CHECK_HEADER'
-
- - Macro: AC_HEADER_EGREP
- `AC_EGREP_HEADER'
-
- - Macro: AC_INIT (UNIQUE-FILE-IN-SOURCE-DIR)
- Formerly `AC_INIT' used to have a single argument, and was
- equivalent to:
-
- AC_INIT
- AC_CONFIG_SRCDIR(UNIQUE-FILE-IN-SOURCE-DIR)
-
- - Macro: AC_INLINE
- `AC_C_INLINE'
-
- - Macro: AC_INT_16_BITS
- If the C type `int' is 16 bits wide, define `INT_16_BITS'. Use
- `AC_CHECK_SIZEOF(int)' instead.
-
- - Macro: AC_IRIX_SUN
- If on IRIX (Silicon Graphics UNIX), add `-lsun' to output `LIBS'.
- If you were using it to get `getmntent', use `AC_FUNC_GETMNTENT'
- instead. If you used it for the NIS versions of the password and
- group functions, use `AC_CHECK_LIB(sun, getpwnam)'. Up to
- Autoconf 2.13, it used to be
-
- AC_CHECK_LIB(sun, getmntent, LIBS="-lsun $LIBS")
-
- now it is defined as
-
- AC_FUNC_GETMNTENT
- AC_CHECK_LIB(sun, getpwnam)
-
- - Macro: AC_LANG_C
- Same as `AC_LANG(C)'.
-
- - Macro: AC_LANG_CPLUSPLUS
- Same as `AC_LANG(C++)'.
-
- - Macro: AC_LANG_FORTRAN77
- Same as `AC_LANG(Fortran 77)'.
-
- - Macro: AC_LANG_RESTORE
- Select the LANGUAGE that is saved on the top of the stack, as set
- by `AC_LANG_SAVE', remove it from the stack, and call
- `AC_LANG(LANGUAGE)'.
-
- - Macro: AC_LANG_SAVE
- Remember the current language (as set by `AC_LANG') on a stack.
- The current language does not change. `AC_LANG_PUSH' is preferred.
-
- - Macro: AC_LINK_FILES (SOURCE..., DEST...)
- This is an obsolete version of `AC_CONFIG_LINKS'. An updated
- version of:
-
- AC_LINK_FILES(config/$machine.h config/$obj_format.h,
- host.h object.h)
-
- is:
-
- AC_CONFIG_LINKS(host.h:config/$machine.h
- object.h:config/$obj_format.h)
-
- - Macro: AC_LN_S
- `AC_PROG_LN_S'
-
- - Macro: AC_LONG_64_BITS
- Define `LONG_64_BITS' if the C type `long int' is 64 bits wide.
- Use the generic macro `AC_CHECK_SIZEOF([long int])' instead.
-
- - Macro: AC_LONG_DOUBLE
- `AC_C_LONG_DOUBLE'
-
- - Macro: AC_LONG_FILE_NAMES
- `AC_SYS_LONG_FILE_NAMES'
-
- - Macro: AC_MAJOR_HEADER
- `AC_HEADER_MAJOR'
-
- - Macro: AC_MEMORY_H
- Used to define `NEED_MEMORY_H' if the `mem' functions were defined
- in `memory.h'. Today it is equivalent to
- `AC_CHECK_HEADERS(memory.h)'. Adjust your code to depend upon
- `HAVE_MEMORY_H', not `NEED_MEMORY_H', see *Note Standard Symbols::.
-
- - Macro: AC_MINGW32
- Similar to `AC_CYGWIN' but checks for the MingW32 compiler
- environment and sets `MINGW32'.
-
- - Macro: AC_MINUS_C_MINUS_O
- `AC_PROG_CC_C_O'
-
- - Macro: AC_MMAP
- `AC_FUNC_MMAP'
-
- - Macro: AC_MODE_T
- `AC_TYPE_MODE_T'
-
- - Macro: AC_OBJEXT
- Defined the output variable `OBJEXT' based on the output of the
- compiler, after .c files have been excluded. Typically set to `o'
- if Unix, `obj' if Win32. Now the compiler checking macros handle
- this automatically.
-
- - Macro: AC_OBSOLETE (THIS-MACRO-NAME, [SUGGESTION])
- Make `m4' print a message to the standard error output warning that
- THIS-MACRO-NAME is obsolete, and giving the file and line number
- where it was called. THIS-MACRO-NAME should be the name of the
- macro that is calling `AC_OBSOLETE'. If SUGGESTION is given, it
- is printed at the end of the warning message; for example, it can
- be a suggestion for what to use instead of THIS-MACRO-NAME.
-
- For instance
-
- AC_OBSOLETE([$0], [; use AC_CHECK_HEADERS(unistd.h) instead])dnl
-
- You are encouraged to use `AU_DEFUN' instead, since it gives better
- services to the user.
-
- - Macro: AC_OFF_T
- `AC_TYPE_OFF_T'
-
- - Macro: AC_OUTPUT ([FILE]..., [EXTRA-CMDS], [INIT-CMDS])
- The use of `AC_OUTPUT' with argument is deprecated, this obsoleted
- interface is equivalent to:
-
- AC_CONFIG_FILES(FILE...)
- AC_CONFIG_COMMANDS([default],
- EXTRA-CMDS, INIT-CMDS)
- AC_OUTPUT
-
- - Macro: AC_OUTPUT_COMMANDS (EXTRA-CMDS, [INIT-CMDS])
- Specify additional shell commands to run at the end of
- `config.status', and shell commands to initialize any variables
- from `configure'. This macro may be called multiple times. It is
- obsolete, replaced by `AC_CONFIG_COMMANDS'.
-
- Here is an unrealistic example:
-
- fubar=27
- AC_OUTPUT_COMMANDS([echo this is extra $fubar, and so on.],
- fubar=$fubar)
- AC_OUTPUT_COMMANDS([echo this is another, extra, bit],
- [echo init bit])
-
- Aside from the fact that `AC_CONFIG_COMMANDS' requires an
- additional key, an important difference is that
- `AC_OUTPUT_COMMANDS' is quoting its arguments twice, while
- `AC_CONFIG_COMMANDS'. This means that `AC_CONFIG_COMMANDS' can
- safely be given macro calls as arguments:
-
- AC_CONFIG_COMMANDS(foo, [my_FOO()])
-
- conversely, where one level of quoting was enough for literal
- strings with `AC_OUTPUT_COMMANDS', you need two with
- `AC_CONFIG_COMMANDS'. The following lines are equivalent:
-
- AC_OUTPUT_COMMANDS([echo "Square brackets: []"])
- AC_CONFIG_COMMANDS(default, [[echo "Square brackets: []"]])
-
- - Macro: AC_PID_T
- `AC_TYPE_PID_T'
-
- - Macro: AC_PREFIX
- `AC_PREFIX_PROGRAM'
-
- - Macro: AC_PROGRAMS_CHECK
- `AC_CHECK_PROGS'
-
- - Macro: AC_PROGRAMS_PATH
- `AC_PATH_PROGS'

-Upgrading From Version 1
-========================
-
- Autoconf version 2 is mostly backward compatible with version 1.
-However, it introduces better ways to do some things, and doesn't
-support some of the ugly things in version 1. So, depending on how
-sophisticated your `configure.ac' files are, you might have to do some
-manual work in order to upgrade to version 2. This chapter points out
-some problems to watch for when upgrading. Also, perhaps your
-`configure' scripts could benefit from some of the new features in
-version 2; the changes are summarized in the file `NEWS' in the
-Autoconf distribution.
-

-
-* Changed File Names:: Files you might rename
-* Changed Makefiles:: New things to put in `Makefile.in'

-
-
-File: autoconf.info, Node: Changed File Names, Next: Changed Makefiles, Prev: Autoconf 1, Up: Autoconf 1
-
-Changed File Names
-------------------
-
- If you have an `aclocal.m4' installed with Autoconf (as opposed to
-in a particular package's source directory), you must rename it to
-`acsite.m4'. *Note autoconf Invocation::.
-
- If you distribute `install.sh' with your package, rename it to
-`install-sh' so `make' builtin rules won't inadvertently create a file
-called `install' from it. `AC_PROG_INSTALL' looks for the script under
-both names, but it is best to use the new name.
-
- If you were using `config.h.top', `config.h.bot', or `acconfig.h',
-you still can, but you will have less clutter if you use the `AH_'
-macros. *Note Autoheader Macros::.
-
-
-File: autoconf.info, Node: Changed Makefiles, Next: Changed Macros, Prev: Changed File Names, Up: Autoconf 1
-
-Changed Makefiles
------------------
-
- Add `@CFLAGS@', `@CPPFLAGS@', and `@LDFLAGS@' in your `Makefile.in'
-files, so they can take advantage of the values of those variables in
-the environment when `configure' is run. Doing this isn't necessary,
-but it's a convenience for users.
-
- Also add `@configure_input@' in a comment to each input file for
-`AC_OUTPUT', so that the output files will contain a comment saying
-they were produced by `configure'. Automatically selecting the right
-comment syntax for all the kinds of files that people call `AC_OUTPUT'
-on became too much work.
-
- Add `config.log' and `config.cache' to the list of files you remove
-in `distclean' targets.
-
- If you have the following in `Makefile.in':
-
- prefix = /usr/local
- exec_prefix = $(prefix)
-
-you must change it to:
-
- prefix = @prefix@
- exec_prefix = @exec_prefix@
-
-The old behavior of replacing those variables without `@' characters
-around them has been removed.
-
-
-File: autoconf.info, Node: Changed Macros, Next: Changed Results, Prev: Changed Makefiles, Up: Autoconf 1
-
-Changed Macros
---------------
-
- Many of the macros were renamed in Autoconf version 2. You can still
-use the old names, but the new ones are clearer, and it's easier to find
-the documentation for them. *Note Obsolete Macros::, for a table
-showing the new names for the old macros. Use the `autoupdate' program
-to convert your `configure.ac' to using the new macro names. *Note
-autoupdate Invocation::.
-
- Some macros have been superseded by similar ones that do the job
-better, but are not call-compatible. If you get warnings about calling
-obsolete macros while running `autoconf', you may safely ignore them,
-but your `configure' script will generally work better if you follow
-the advice it prints about what to replace the obsolete macros with. In
-particular, the mechanism for reporting the results of tests has
-changed. If you were using `echo' or `AC_VERBOSE' (perhaps via
-`AC_COMPILE_CHECK'), your `configure' script's output will look better
-if you switch to `AC_MSG_CHECKING' and `AC_MSG_RESULT'. *Note Printing
-Messages::. Those macros work best in conjunction with cache
-variables. *Note Caching Results::.
-
-
-File: autoconf.info, Node: Changed Results, Next: Changed Macro Writing, Prev: Changed Macros, Up: Autoconf 1
-
-Changed Results
----------------
-
- If you were checking the results of previous tests by examining the
-shell variable `DEFS', you need to switch to checking the values of the
-cache variables for those tests. `DEFS' no longer exists while
-`configure' is running; it is only created when generating output
-files. This difference from version 1 is because properly quoting the
-contents of that variable turned out to be too cumbersome and
-inefficient to do every time `AC_DEFINE' is called. *Note Cache
-Variable Names::.
-
- For example, here is a `configure.ac' fragment written for Autoconf
-version 1:
-
- AC_HAVE_FUNCS(syslog)
- case "$DEFS" in
- *-DHAVE_SYSLOG*) ;;
- *) # syslog is not in the default libraries. See if it's in some other.
- saved_LIBS="$LIBS"
- for lib in bsd socket inet; do
- AC_CHECKING(for syslog in -l$lib)
- LIBS="$saved_LIBS -l$lib"
- AC_HAVE_FUNCS(syslog)
- case "$DEFS" in
- *-DHAVE_SYSLOG*) break ;;
- *) ;;
- esac
- LIBS="$saved_LIBS"
- done ;;
- esac
-
- Here is a way to write it for version 2:
-
- AC_CHECK_FUNCS(syslog)
- if test $ac_cv_func_syslog = no; then
- # syslog is not in the default libraries. See if it's in some other.
- for lib in bsd socket inet; do
- AC_CHECK_LIB($lib, syslog, [AC_DEFINE(HAVE_SYSLOG)
- LIBS="$LIBS -l$lib"; break])
- done
- fi
-
- If you were working around bugs in `AC_DEFINE_UNQUOTED' by adding
-backslashes before quotes, you need to remove them. It now works
-predictably, and does not treat quotes (except back quotes) specially.
-*Note Setting Output Variables::.
-
- All of the boolean shell variables set by Autoconf macros now use
-`yes' for the true value. Most of them use `no' for false, though for
-backward compatibility some use the empty string instead. If you were
-relying on a shell variable being set to something like 1 or `t' for
-true, you need to change your tests.
-
-
-File: autoconf.info, Node: Changed Macro Writing, Prev: Changed Results, Up: Autoconf 1
-
-Changed Macro Writing
----------------------
-
- When defining your own macros, you should now use `AC_DEFUN' instead
-of `define'. `AC_DEFUN' automatically calls `AC_PROVIDE' and ensures
-that macros called via `AC_REQUIRE' do not interrupt other macros, to
-prevent nested `checking...' messages on the screen. There's no actual
-harm in continuing to use the older way, but it's less convenient and
-attractive. *Note Macro Definitions::.
-
- You probably looked at the macros that came with Autoconf as a guide
-for how to do things. It would be a good idea to take a look at the new
-versions of them, as the style is somewhat improved and they take
-advantage of some new features.
-
- If you were doing tricky things with undocumented Autoconf internals
-(macros, variables, diversions), check whether you need to change
-anything to account for changes that have been made. Perhaps you can
-even use an officially supported technique in version 2 instead of
-kludging. Or perhaps not.
-
- To speed up your locally written feature tests, add caching to them.
-See whether any of your tests are of general enough usefulness to
-encapsulate into macros that you can share.

-Upgrading From Version 2.13
-===========================
-
- The introduction of the previous section (*note Autoconf 1::)
-perfectly suits this section...
-
- Autoconf version 2.50 is mostly backward compatible with version
- 2.13. However, it introduces better ways to do some things, and
- doesn't support some of the ugly things in version 2.13. So,
- depending on how sophisticated your `configure.ac' files are, you
- might have to do some manual work in order to upgrade to version
- 2.50. This chapter points out some problems to watch for when
- upgrading. Also, perhaps your `configure' scripts could benefit
- from some of the new features in version 2.50; the changes are
- summarized in the file `NEWS' in the Autoconf distribution.

-* New Macros:: Interaction with foreign macros
-
-
-File: autoconf.info, Node: Changed Quotation, Next: New Macros, Prev: Autoconf 2.13, Up: Autoconf 2.13
-
-Changed Quotation
------------------
-
- The most important changes are invisible to you: the implementation
-of most macros have completely changed. This allowed more
-factorization of the code, better error messages, a higher uniformity
-of the user's interface etc. Unfortunately, as a side effect, some
-construct which used to (miraculously) work might break starting with
-Autoconf 2.50. The most common culprit is bad quotation.
-
- For instance, in the following example, the message is not properly
-quoted:
-
- AC_INIT
- AC_CHECK_HEADERS(foo.h,,
- AC_MSG_ERROR(cannot find foo.h, bailing out))
- AC_OUTPUT
-
-Autoconf 2.13 simply ignores it:
-
- $ autoconf-2.13; ./configure --silent
- creating cache ./config.cache
- configure: error: cannot find foo.h
- $
-
-while Autoconf 2.50 will produce a broken `configure':
-
- $ autoconf-2.50; ./configure --silent
- configure: error: cannot find foo.h
- ./configure: exit: bad non-numeric arg `bailing'
- ./configure: exit: bad non-numeric arg `bailing'
- $
-
- The message needs to be quoted, and the `AC_MSG_ERROR' invocation
-too!
-
- AC_INIT
- AC_CHECK_HEADERS(foo.h,,
- [AC_MSG_ERROR([cannot find foo.h, bailing out])])
- AC_OUTPUT
-
- Many many (and many more) Autoconf macros were lacking proper
-quotation, including no less than... `AC_DEFUN' itself!
-
- $ cat configure.in
- AC_DEFUN([AC_PROG_INSTALL],
- [# My own much better version
- ])
- AC_INIT
- AC_PROG_INSTALL
- AC_OUTPUT
- $ autoconf-2.13
- autoconf: Undefined macros:
- ***BUG in Autoconf--please report*** AC_FD_MSG
- ***BUG in Autoconf--please report*** AC_EPI
- configure.in:1:AC_DEFUN([AC_PROG_INSTALL],
- configure.in:5:AC_PROG_INSTALL
- $ autoconf-2.50
- $
-
-
-File: autoconf.info, Node: New Macros, Prev: Changed Quotation, Up: Autoconf 2.13
-
-New Macros
-----------
-
- Because Autoconf has been dormant for years, Automake provided
-Autoconf-like macros for a while. Autoconf 2.50 now provides better
-versions of these macros, integrated in the `AC_' namespace, instead of
-`AM_'. But in order to ease the upgrading via `autoupdate', bindings
-to such `AM_' macros are provided.
-
- Unfortunately Automake did not quote the name of these macros!
-Therefore, when `m4' find in `aclocal.m4' something like
-`AC_DEFUN(AM_TYPE_PTRDIFF_T, ...)', `AM_TYPE_PTRDIFF_T' is expanded,
-replaced with its Autoconf definition.
-
- Fortunately Autoconf catches pre-`AC_INIT' expansions, and will
-complain, in its own words:
-
- $ cat configure.in
- AC_INIT
- AM_TYPE_PTRDIFF_T
- $ aclocal-1.4
- $ autoconf
- ./aclocal.m4:17: error: m4_defn: undefined macro: _m4_divert_diversion
- actypes.m4:289: AM_TYPE_PTRDIFF_T is expanded from...
- ./aclocal.m4:17: the top level
- $
-
- Future versions of Automake will simply no longer define most of
-these macros, and will properly quote the names of the remaining macros.
-But you don't have to wait for it to happen to do the right thing right
-now: do not depend upon macros from Automake as it is simply not its job
-to provide macros (but the one it requires by itself):
-
- $ cat configure.in
- AC_INIT
- AM_TYPE_PTRDIFF_T
- $ rm aclocal.m4
- $ autoupdate
- autoupdate: `configure.in' is updated
- $ cat configure.in
- AC_INIT
- AC_CHECK_TYPES([ptrdiff_t])
- $ aclocal-1.4
- $ autoconf

-
-Distributing `configure' Scripts
-================================
-
- What are the restrictions on distributing `configure'
- scripts that Autoconf generates? How does that affect my
- programs that use them?
-
- There are no restrictions on how the configuration scripts that
-Autoconf produces may be distributed or used. In Autoconf version 1,
-they were covered by the GNU General Public License. We still encourage
-software authors to distribute their work under terms like those of the
-GPL, but doing so is not required to use Autoconf.
-
- Of the other files that might be used with `configure',
-`config.h.in' is under whatever copyright you use for your
-`configure.ac'. `config.sub' and `config.guess' have an exception to
-the GPL when they are used with an Autoconf-generated `configure'
-script, which permits you to distribute them under the same terms as
-the rest of your package. `install-sh' is from the X Consortium and is
-not copyrighted.
-
-
-File: autoconf.info, Node: Why GNU m4, Next: Bootstrapping, Prev: Distributing, Up: Questions
-
-Why Require GNU M4?
-===================
-
- Why does Autoconf require GNU M4?
-
- Many M4 implementations have hard-coded limitations on the size and
-number of macros that Autoconf exceeds. They also lack several builtin
-macros that it would be difficult to get along without in a
-sophisticated application like Autoconf, including:
-
- builtin
- indir
- patsubst
- __file__
- __line__
-
- Autoconf requires version 1.4 or above of GNU M4 because it uses
-frozen state files.
-
- Since only software maintainers need to use Autoconf, and since GNU
-M4 is simple to configure and install, it seems reasonable to require
-GNU M4 to be installed also. Many maintainers of GNU and other free
-software already have most of the GNU utilities installed, since they
-prefer them.
-
-
-File: autoconf.info, Node: Bootstrapping, Next: Why Not Imake, Prev: Why GNU m4, Up: Questions
-
-How Can I Bootstrap?
-====================
-
- If Autoconf requires GNU M4 and GNU M4 has an Autoconf
- `configure' script, how do I bootstrap? It seems like a chicken
- and egg problem!
-
- This is a misunderstanding. Although GNU M4 does come with a
-`configure' script produced by Autoconf, Autoconf is not required in
-order to run the script and install GNU M4. Autoconf is only required
-if you want to change the M4 `configure' script, which few people have
-to do (mainly its maintainer).
-
-
-File: autoconf.info, Node: Why Not Imake, Prev: Bootstrapping, Up: Questions
-
-Why Not Imake?
-==============
-
- Why not use Imake instead of `configure' scripts?
-
- Several people have written addressing this question, so I include
-adaptations of their explanations here.
-
- The following answer is based on one written by Richard Pixley:
-
- Autoconf generated scripts frequently work on machines that it has
- never been set up to handle before. That is, it does a good job of
- inferring a configuration for a new system. Imake cannot do this.
-
- Imake uses a common database of host specific data. For X11, this
- makes sense because the distribution is made as a collection of
- tools, by one central authority who has control over the database.
-
- GNU tools are not released this way. Each GNU tool has a
- maintainer; these maintainers are scattered across the world.
- Using a common database would be a maintenance nightmare.
- Autoconf may appear to be this kind of database, but in fact it is
- not. Instead of listing host dependencies, it lists program
- requirements.
-
- If you view the GNU suite as a collection of native tools, then the
- problems are similar. But the GNU development tools can be
- configured as cross tools in almost any host+target permutation.
- All of these configurations can be installed concurrently. They
- can even be configured to share host independent files across
- hosts. Imake doesn't address these issues.
-
- Imake templates are a form of standardization. The GNU coding
- standards address the same issues without necessarily imposing the
- same restrictions.
-
- Here is some further explanation, written by Per Bothner:
-
- One of the advantages of Imake is that it easy to generate large
- Makefiles using `cpp''s `#include' and macro mechanisms. However,
- `cpp' is not programmable: it has limited conditional facilities,
- and no looping. And `cpp' cannot inspect its environment.
-
- All of these problems are solved by using `sh' instead of `cpp'.
- The shell is fully programmable, has macro substitution, can
- execute (or source) other shell scripts, and can inspect its
- environment.
-
- Paul Eggert elaborates more:
-
- With Autoconf, installers need not assume that Imake itself is
- already installed and working well. This may not seem like much
- of an advantage to people who are accustomed to Imake. But on
- many hosts Imake is not installed or the default installation is
- not working well, and requiring Imake to install a package hinders
- the acceptance of that package on those hosts. For example, the
- Imake template and configuration files might not be installed
- properly on a host, or the Imake build procedure might wrongly
- assume that all source files are in one big directory tree, or the
- Imake configuration might assume one compiler whereas the package
- or the installer needs to use another, or there might be a version
- mismatch between the Imake expected by the package and the Imake
- supported by the host. These problems are much rarer with
- Autoconf, where each package comes with its own independent
- configuration processor.
-
- Also, Imake often suffers from unexpected interactions between
- `make' and the installer's C preprocessor. The fundamental problem
- here is that the C preprocessor was designed to preprocess C
- programs, not `Makefile's. This is much less of a problem with
- Autoconf, which uses the general-purpose preprocessor `m4', and
- where the package's author (rather than the installer) does the
- preprocessing in a standard way.
-
- Finally, Mark Eichin notes:
-
- Imake isn't all that extensible, either. In order to add new
- features to Imake, you need to provide your own project template,
- and duplicate most of the features of the existing one. This
- means that for a sophisticated project, using the vendor-provided
- Imake templates fails to provide any leverage--since they don't
- cover anything that your own project needs (unless it is an X11
- program).
-
- On the other side, though:
-
- The one advantage that Imake has over `configure': `Imakefile's
- tend to be much shorter (likewise, less redundant) than
- `Makefile.in's. There is a fix to this, however--at least for the
- Kerberos V5 tree, we've modified things to call in common
- `post.in' and `pre.in' `Makefile' fragments for the entire tree.
- This means that a lot of common things don't have to be
- duplicated, even though they normally are in `configure' setups.

-you're not wondering, then this chapter contains no information useful
-to you, and you might as well skip it. If you _are_ wondering, then

-Genesis
-=======
-
- In June 1991 I was maintaining many of the GNU utilities for the
-Free Software Foundation. As they were ported to more platforms and
-more programs were added, the number of `-D' options that users had to
-select in the `Makefile' (around 20) became burdensome. Especially for
-me--I had to test each new release on a bunch of different systems. So
-I wrote a little shell script to guess some of the correct settings for
-the fileutils package, and released it as part of fileutils 2.0. That
-`configure' script worked well enough that the next month I adapted it
-(by hand) to create similar `configure' scripts for several other GNU
-utilities packages. Brian Berliner also adapted one of my scripts for
-his CVS revision control system.
-
- Later that summer, I learned that Richard Stallman and Richard Pixley
-were developing similar scripts to use in the GNU compiler tools; so I
-adapted my `configure' scripts to support their evolving interface:
-using the file name `Makefile.in' as the templates; adding `+srcdir',
-the first option (of many); and creating `config.status' files.
-
-
-File: autoconf.info, Node: Exodus, Next: Leviticus, Prev: Genesis, Up: History
-
-Exodus
-======
-
- As I got feedback from users, I incorporated many improvements, using
-Emacs to search and replace, cut and paste, similar changes in each of
-the scripts. As I adapted more GNU utilities packages to use
-`configure' scripts, updating them all by hand became impractical.
-Rich Murphey, the maintainer of the GNU graphics utilities, sent me
-mail saying that the `configure' scripts were great, and asking if I
-had a tool for generating them that I could send him. No, I thought,
-but I should! So I started to work out how to generate them. And the
-journey from the slavery of hand-written `configure' scripts to the
-abundance and ease of Autoconf began.
-
- Cygnus `configure', which was being developed at around that time,
-is table driven; it is meant to deal mainly with a discrete number of
-system types with a small number of mainly unguessable features (such as
-details of the object file format). The automatic configuration system
-that Brian Fox had developed for Bash takes a similar approach. For
-general use, it seems to me a hopeless cause to try to maintain an
-up-to-date database of which features each variant of each operating
-system has. It's easier and more reliable to check for most features on
-the fly--especially on hybrid systems that people have hacked on
-locally or that have patches from vendors installed.
-
- I considered using an architecture similar to that of Cygnus
-`configure', where there is a single `configure' script that reads
-pieces of `configure.in' when run. But I didn't want to have to
-distribute all of the feature tests with every package, so I settled on
-having a different `configure' made from each `configure.in' by a
-preprocessor. That approach also offered more control and flexibility.
-
- I looked briefly into using the Metaconfig package, by Larry Wall,
-Harlan Stenn, and Raphael Manfredi, but I decided not to for several
-reasons. The `Configure' scripts it produces are interactive, which I
-find quite inconvenient; I didn't like the ways it checked for some
-features (such as library functions); I didn't know that it was still
-being maintained, and the `Configure' scripts I had seen didn't work on
-many modern systems (such as System V R4 and NeXT); it wasn't very
-flexible in what it could do in response to a feature's presence or
-absence; I found it confusing to learn; and it was too big and complex
-for my needs (I didn't realize then how much Autoconf would eventually
-have to grow).
-
- I considered using Perl to generate my style of `configure' scripts,
-but decided that M4 was better suited to the job of simple textual
-substitutions: it gets in the way less, because output is implicit.
-Plus, everyone already has it. (Initially I didn't rely on the GNU
-extensions to M4.) Also, some of my friends at the University of
-Maryland had recently been putting M4 front ends on several programs,
-including `tvtwm', and I was interested in trying out a new language.

-=========
-
- Since my `configure' scripts determine the system's capabilities
-automatically, with no interactive user intervention, I decided to call
-the program that generates them Autoconfig. But with a version number
-tacked on, that name would be too long for old UNIX file systems, so I
-shortened it to Autoconf.
-
- In the fall of 1991 I called together a group of fellow questers
-after the Holy Grail of portability (er, that is, alpha testers) to
-give me feedback as I encapsulated pieces of my handwritten scripts in
-M4 macros and continued to add features and improve the techniques used
-in the checks. Prominent among the testers were Franc,ois Pinard, who
-came up with the idea of making an `autoconf' shell script to run `m4'
-and check for unresolved macro calls; Richard Pixley, who suggested
-running the compiler instead of searching the file system to find
-include files and symbols, for more accurate results; Karl Berry, who
-got Autoconf to configure TeX and added the macro index to the
-documentation; and Ian Lance Taylor, who added support for creating a C
-header file as an alternative to putting `-D' options in a `Makefile',
-so he could use Autoconf for his UUCP package. The alpha testers
-cheerfully adjusted their files again and again as the names and
-calling conventions of the Autoconf macros changed from release to
-release. They all contributed many specific checks, great ideas, and
-bug fixes.

-=======
-
- In July 1992, after months of alpha testing, I released Autoconf 1.0,
-and converted many GNU packages to use it. I was surprised by how
-positive the reaction to it was. More people started using it than I
-could keep track of, including people working on software that wasn't
-part of the GNU Project (such as TCL, FSP, and Kerberos V5). Autoconf
-continued to improve rapidly, as many people using the `configure'
-scripts reported problems they encountered.
-
- Autoconf turned out to be a good torture test for M4 implementations.
-UNIX `m4' started to dump core because of the length of the macros that
-Autoconf defined, and several bugs showed up in GNU `m4' as well.
-Eventually, we realized that we needed to use some features that only
-GNU M4 has. 4.3BSD `m4', in particular, has an impoverished set of
-builtin macros; the System V version is better, but still doesn't
-provide everything we need.
-
- More development occurred as people put Autoconf under more stresses
-(and to uses I hadn't anticipated). Karl Berry added checks for X11.
-david zuhn contributed C++ support. Franc,ois Pinard made it diagnose
-invalid arguments. Jim Blandy bravely coerced it into configuring GNU
-Emacs, laying the groundwork for several later improvements. Roland
-McGrath got it to configure the GNU C Library, wrote the `autoheader'
-script to automate the creation of C header file templates, and added a
-`--verbose' option to `configure'. Noah Friedman added the
-`--autoconf-dir' option and `AC_MACRODIR' environment variable. (He
-also coined the term "autoconfiscate" to mean "adapt a software package
-to use Autoconf".) Roland and Noah improved the quoting protection in
-`AC_DEFINE' and fixed many bugs, especially when I got sick of dealing
-with portability problems from February through June, 1993.

-===========
-
- A long wish list for major features had accumulated, and the effect
-of several years of patching by various people had left some residual
-cruft. In April 1994, while working for Cygnus Support, I began a major
-revision of Autoconf. I added most of the features of the Cygnus
-`configure' that Autoconf had lacked, largely by adapting the relevant
-parts of Cygnus `configure' with the help of david zuhn and Ken
-Raeburn. These features include support for using `config.sub',
-`config.guess', `--host', and `--target'; making links to files; and
-running `configure' scripts in subdirectories. Adding these features
-enabled Ken to convert GNU `as', and Rob Savoye to convert DejaGNU, to
-using Autoconf.
-
- I added more features in response to other peoples' requests. Many
-people had asked for `configure' scripts to share the results of the
-checks between runs, because (particularly when configuring a large
-source tree, like Cygnus does) they were frustratingly slow. Mike
-Haertel suggested adding site-specific initialization scripts. People
-distributing software that had to unpack on MS-DOS asked for a way to
-override the `.in' extension on the file names, which produced file
-names like `config.h.in' containing two dots. Jim Avera did an
-extensive examination of the problems with quoting in `AC_DEFINE' and
-`AC_SUBST'; his insights led to significant improvements. Richard
-Stallman asked that compiler output be sent to `config.log' instead of
-`/dev/null', to help people debug the Emacs `configure' script.
-
- I made some other changes because of my dissatisfaction with the
-quality of the program. I made the messages showing results of the
-checks less ambiguous, always printing a result. I regularized the
-names of the macros and cleaned up coding style inconsistencies. I
-added some auxiliary utilities that I had developed to help convert
-source code packages to use Autoconf. With the help of Franc,ois
-Pinard, I made the macros not interrupt each others' messages. (That
-feature revealed some performance bottlenecks in GNU `m4', which he
-hastily corrected!) I reorganized the documentation around problems
-people want to solve. And I began a test suite, because experience had
-shown that Autoconf has a pronounced tendency to regress when we change
-it.
-
- Again, several alpha testers gave invaluable feedback, especially
-Franc,ois Pinard, Jim Meyering, Karl Berry, Rob Savoye, Ken Raeburn,
-and Mark Eichin.
-
- Finally, version 2.0 was ready. And there was much rejoicing. (And
-I have free time again. I think. Yeah, right.)

-## Common m4/sh handling of variables (indirections). ##
-## --------------------------------------------------- ##
-
-
-# The purpose of this section is to provide a uniform API for
-# reading/setting sh variables with or without indirection.
-# Typically, one can write
-# AS_VAR_SET(var, val)
-# or
-# AS_VAR_SET(as_$var, val)
-# and expect the right thing to happen.
-
-
-# AS_VAR_SET(VARIABLE, VALUE)
-# ---------------------------
-# Set the VALUE of the shell VARIABLE.
-# If the variable contains indirections (e.g. `ac_cv_func_$ac_func')
-# perform whenever possible at m4 level, otherwise sh level.
-m4_define([AS_VAR_SET],
-[AS_LITERAL_IF([$1],
- [$1=$2],
- [eval "$1=$2"])])
-
-
-# AS_VAR_GET(VARIABLE)
-# --------------------
-# Get the value of the shell VARIABLE.
-# Evaluates to $VARIABLE if there are no indirection in VARIABLE,
-# else into the appropriate `eval' sequence.
-m4_define([AS_VAR_GET],
-[AS_LITERAL_IF([$1],
- [$[]$1],
- [`eval echo '${'m4_patsubst($1, [[\\`]], [\\\&])'}'`])])
-
-
-# AS_VAR_TEST_SET(VARIABLE)
-# -------------------------
-# Expands into the `test' expression which is true if VARIABLE
-# is set. Polymorphic. Should be dnl'ed.
-m4_define([AS_VAR_TEST_SET],
-[AS_LITERAL_IF([$1],
- [test "${$1+set}" = set],
- [eval "test \"\${$1+set}\" = set"])])
-
-

-# or not. Polymorphic.

-
-
-# AS_VAR_PUSHDEF and AS_VAR_POPDEF
-# --------------------------------
-#
-
-# Sometimes we may have to handle literals (e.g. `stdlib.h'), while at
-# other moments, the same code may have to get the value from a
-# variable (e.g., `ac_header'). To have a uniform handling of both
-# cases, when a new value is about to be processed, declare a local
-# variable, e.g.:
-#
-# AS_VAR_PUSHDEF([header], [ac_cv_header_$1])
-#
-# and then in the body of the macro, use `header' as is. It is of
-# first importance to use `AS_VAR_*' to access this variable. Don't
-# quote its name: it must be used right away by m4.
-#
-# If the value `$1' was a literal (e.g. `stdlib.h'), then `header' is
-# in fact the value `ac_cv_header_stdlib_h'. If `$1' was indirect,
-# then `header's value in m4 is in fact `$ac_header', the shell
-# variable that holds all of the magic to get the expansion right.
-#
-# At the end of the block, free the variable with
-#
-# AS_VAR_POPDEF([header])
-
-
-# AS_VAR_PUSHDEF(VARNAME, VALUE)
-# ------------------------------
-# Define the m4 macro VARNAME to an accessor to the shell variable
-# named VALUE. VALUE does not need to be a valid shell variable name:
-# the transliteration is handled here. To be dnl'ed.
-m4_define([AS_VAR_PUSHDEF],

-# Both `m4_ifval' and `m4_ifset' tests against the empty string. The

-#
-# In case of arguments of macros, eg $[1], it makes little difference.
-# In the case of a macro `FOO', you don't want to check `m4_ifval(FOO,

-# the arguments. So you want to run `m4_ifval([FOO])', but then you just
-# compare the *string* `FOO' against `', which, of course fails.

-# Implementing `foreach' loops in m4 is much more tricky than it may
-# seem. Actually, the example of a `foreach' loop in the m4
-# documentation is wrong: it does not quote the arguments properly,
-# which leads to undesired expansions.
-#
-# The example in the documentation is:
-#
-# | # foreach(VAR, (LIST), STMT)
-# | m4_define([foreach],
-# | [m4_pushdef([$1])_foreach([$1], [$2], [$3])m4_popdef([$1])])
-# | m4_define([_arg1], [$1])
-# | m4_define([_foreach],
-# | [m4_if([$2], [()], ,
-# | [m4_define([$1], _arg1$2)$3[]_foreach([$1],
-# | (shift$2),
-# | [$3])])])
-#
-# But then if you run
-#
-# | m4_define(a, 1)
-# | m4_define(b, 2)
-# | m4_define(c, 3)
-# | foreach([f], [([a], [(b], [c)])], [echo f
-# | ])
-#
-# it gives
-#
-# => echo 1
-# => echo (2,3)
-#
-# which is not what is expected.
-#
-# Of course the problem is that many quotes are missing. So you add
-# plenty of quotes at random places, until you reach the expected
-# result. Alternatively, if you are a quoting wizard, you directly
-# reach the following implementation (but if you really did, then
-# apply to the maintenance of m4sugar!).
-#
-# | # foreach(VAR, (LIST), STMT)
-# | m4_define([foreach], [m4_pushdef([$1])_foreach($@)m4_popdef([$1])])
-# | m4_define([_arg1], [[$1]])
-# | m4_define([_foreach],
-# | [m4_if($2, [()], ,
-# | [m4_define([$1], [_arg1$2])$3[]_foreach([$1],
-# | [(shift$2)],
-# | [$3])])])
-#
-# which this time answers
-#
-# => echo a
-# => echo (b
-# => echo c)
-#
-# Bingo!
-#
-# Well, not quite.
-#
-# With a better look, you realize that the parens are more a pain than
-# a help: since anyway you need to quote properly the list, you end up
-# with always using an outermost pair of parens and an outermost pair
-# of quotes. Rejecting the parens both eases the implementation, and
-# simplifies the use:
-#
-# | # foreach(VAR, (LIST), STMT)
-# | m4_define([foreach], [m4_pushdef([$1])_foreach($@)m4_popdef([$1])])

-# | [m4_define([$1], [_arg1($2)])$3[]_foreach([$1],
-# | [shift($2)],
-# | [$3])])])
-#
-#
-# Now, just replace the `$2' with `m4_quote($2)' in the outer `m4_if'
-# to improve robustness, and you come up with a quite satisfactory
-# implementation.

-## -------------------------------------------- ##
-## 8. Defining macros with bells and whistles. ##
-## -------------------------------------------- ##
-
-# `m4_defun' is basically `m4_define' but it equips the macro with the
-# needed machinery for `m4_require'. A macro must be m4_defun'd if
-# either it is m4_require'd, or it m4_require's.
-#
-# Two things deserve attention and are detailed below:
-# 1. Implementation of m4_require
-# 2. Keeping track of the expansion stack
-#
-# 1. Implementation of m4_require
-# ===============================
-#
-# Of course m4_defun AC_PROVIDE's the macro, so that a macro which has
-# been expanded is not expanded again when m4_require'd, but the
-# difficult part is the proper expansion of macros when they are
-# m4_require'd.
-#
-# The implementation is based on two ideas, (i) using diversions to
-# prepare the expansion of the macro and its dependencies (by François
-# Pinard), and (ii) expand the most recently m4_require'd macros _after_
-# the previous macros (by Axel Thimm).
-#
-#
-# The first idea: why using diversions?
-# -------------------------------------
-#
-# When a macro requires another, the other macro is expanded in new
-# diversion, GROW. When the outer macro is fully expanded, we first
-# undivert the most nested diversions (GROW - 1...), and finally
-# undivert GROW. To understand why we need several diversions,
-# consider the following example:
-#
-# | m4_defun([TEST1], [Test...REQUIRE([TEST2])1])
-# | m4_defun([TEST2], [Test...REQUIRE([TEST3])2])
-# | m4_defun([TEST3], [Test...3])
-#
-# Because m4_require is not required to be first in the outer macros, we
-# must keep the expansions of the various level of m4_require separated.
-# Right before executing the epilogue of TEST1, we have:
-#
-# GROW - 2: Test...3
-# GROW - 1: Test...2
-# GROW: Test...1
-# BODY:
-#
-# Finally the epilogue of TEST1 undiverts GROW - 2, GROW - 1, and
-# GROW into the regular flow, BODY.
-#
-# GROW - 2:
-# GROW - 1:
-# GROW:
-# BODY: Test...3; Test...2; Test...1
-#
-# (The semicolons are here for clarification, but of course are not
-# emitted.) This is what Autoconf 2.0 (I think) to 2.13 (I'm sure)
-# implement.
-#
-#
-# The second idea: first required first out
-# -----------------------------------------
-#
-# The natural implementation of the idea above is buggy and produces
-# very surprising results in some situations. Let's consider the
-# following example to explain the bug:
-#
-# | m4_defun([TEST1], [REQUIRE([TEST2a])REQUIRE([TEST2b])])
-# | m4_defun([TEST2a], [])
-# | m4_defun([TEST2b], [REQUIRE([TEST3])])
-# | m4_defun([TEST3], [REQUIRE([TEST2a])])
-# |
-# | AC_INIT
-# | TEST1
-#
-# The dependencies between the macros are:
-#
-# 3 --- 2b
-# / \ is m4_require'd by
-# / \ left -------------------- right
-# 2a ------------ 1
-#
-# If you strictly apply the rules given in the previous section you get:
-#
-# GROW - 2: TEST3
-# GROW - 1: TEST2a; TEST2b
-# GROW: TEST1
-# BODY:
-#
-# (TEST2a, although required by TEST3 is not expanded in GROW - 3
-# because is has already been expanded before in GROW - 1, so it has
-# been AC_PROVIDE'd, so it is not expanded again) so when you undivert
-# the stack of diversions, you get:
-#
-# GROW - 2:
-# GROW - 1:
-# GROW:
-# BODY: TEST3; TEST2a; TEST2b; TEST1
-#
-# i.e., TEST2a is expanded after TEST3 although the latter required the
-# former.
-#
-# Starting from 2.50, uses an implementation provided by Axel Thimm.
-# The idea is simple: the order in which macros are emitted must be the
-# same as the one in which macro are expanded. (The bug above can
-# indeed be described as: a macro has been AC_PROVIDE'd, but it is
-# emitted after: the lack of correlation between emission and expansion
-# order is guilty).
-#
-# How to do that? You keeping the stack of diversions to elaborate the
-# macros, but each time a macro is fully expanded, emit it immediately.
-#
-# In the example above, when TEST2a is expanded, but it's epilogue is
-# not run yet, you have:
-#
-# GROW - 2:
-# GROW - 1: TEST2a
-# GROW: Elaboration of TEST1
-# BODY:
-#
-# The epilogue of TEST2a emits it immediately:
-#
-# GROW - 2:
-# GROW - 1:
-# GROW: Elaboration of TEST1
-# BODY: TEST2a
-#
-# TEST2b then requires TEST3, so right before the epilogue of TEST3, you
-# have:
-#
-# GROW - 2: TEST3
-# GROW - 1: Elaboration of TEST2b
-# GROW: Elaboration of TEST1
-# BODY: TEST2a
-#
-# The epilogue of TEST3 emits it:
-#
-# GROW - 2:
-# GROW - 1: Elaboration of TEST2b
-# GROW: Elaboration of TEST1
-# BODY: TEST2a; TEST3
-#
-# TEST2b is now completely expanded, and emitted:
-#
-# GROW - 2:
-# GROW - 1:
-# GROW: Elaboration of TEST1
-# BODY: TEST2a; TEST3; TEST2b
-#
-# and finally, TEST1 is finished and emitted:
-#
-# GROW - 2:
-# GROW - 1:
-# GROW:
-# BODY: TEST2a; TEST3; TEST2b: TEST1
-#
-# The idea, is simple, but the implementation is a bit evolved. If you
-# are like me, you will want to see the actual functioning of this
-# implementation to be convinced. The next section gives the full
-# details.
-#
-#
-# The Axel Thimm implementation at work
-# -------------------------------------
-#
-# We consider the macros above, and this configure.ac:
-#
-# AC_INIT
-# TEST1
-#
-# You should keep the definitions of _m4_defun_pro, _m4_defun_epi, and
-# m4_require at hand to follow the steps.
-#
-# This implements tries not to assume that of the current diversion is
-# BODY, so as soon as a macro (m4_defun'd) is expanded, we first
-# record the current diversion under the name _m4_divert_dump (denoted
-# DUMP below for short). This introduces an important difference with
-# the previous versions of Autoconf: you cannot use m4_require if you
-# were not inside an m4_defun'd macro, and especially, you cannot
-# m4_require directly from the top level.
-#
-# We have not tried to simulate the old behavior (better yet, we
-# diagnose it), because it is too dangerous: a macro m4_require'd from
-# the top level is expanded before the body of `configure', i.e., before
-# any other test was run. I let you imagine the result of requiring
-# AC_STDC_HEADERS for instance, before AC_PROG_CC was actually run....
-#
-# After AC_INIT was run, the current diversion is BODY.
-# * AC_INIT was run

-#
-# * TEST1 is expanded
-# The prologue of TEST1 sets AC_DIVERSION_DUMP, which is the diversion

-# expansion of TEST1 and its dependencies will be elaborated.

-# 2. Keeping track of the expansion stack
-# =======================================
-#
-# When M4 expansion goes wrong it is often extremely hard to find the
-# path amongst macros that drove to the failure. What is needed is
-# the stack of macro `calls'. One could imagine that GNU M4 would
-# maintain a stack of macro expansions, unfortunately it doesn't, so
-# we do it by hand. This is of course extremely costly, but the help
-# this stack provides is worth it. Nevertheless to limit the
-# performance penalty this is implemented only for m4_defun'd macros,
-# not for define'd macros.
-#
-# The scheme is simplistic: each time we enter an m4_defun'd macros,
-# we prepend its name in m4_expansion_stack, and when we exit the
-# macro, we remove it (thanks to pushdef/popdef).
-#
-# In addition, we want to use the expansion stack to detect circular
-# m4_require dependencies. This means we need to browse the stack to
-# check whether a macro being expanded is m4_require'd. For ease of
-# implementation, and certainly for the benefit of performances, we
-# don't browse the m4_expansion_stack, rather each time we expand a
-# macro FOO we define _m4_expanding(FOO). Then m4_require(BAR) simply
-# needs to check whether _m4_expanding(BAR) is defined to diagnose a
-# circular dependency.
-#
-# To improve the diagnostic, in addition to keeping track of the stack
-# of macro calls, m4_expansion_stack also records the m4_require
-# stack. Note that therefore an m4_defun'd macro being required will
-# appear twice in the stack: the first time because it is required,
-# the second because it is expanded. We can avoid this, but it has
-# two small drawbacks: (i) the implementation is slightly more
-# complex, and (ii) it hides the difference between define'd macros
-# (which don't appear in m4_expansion_stack) and m4_defun'd macros
-# (which do). The more debugging information, the better.

-Run `autoconf' (and `autoheader', `aclocal' and `automake', where
-appropriate) repeatedly to remake the Autoconf `configure' scripts
-and configuration header templates in the directory tree rooted at the
-current directory. By default, it only remakes those files that are

- -*- outline -*-
-
-This directory holds the M4sugar, M4sh and Autoconf test suites.
-
-
-Here are a few rules on how to write tests.
-
-* Order of the tests
-
-It is extremely important to pay attention to the order of the tests.
-There are basically two philosophies: (i) test earlier the most
-critical features (hence hurried users will at least check those), or
-(ii) test earlier the primitives.
-
-For having tried both, I definitely recommend (ii). In practice users
-will run the whole test suite even if it's long. And if they don't,
-there will be enough other users who will do the job.
-
-But also in practice some problems in the core of project can be
-responsible for an incredible number of failures. Then the problems
-at the origin will be hidden by the consequences. If dependencies are
-properly ordered in the test suite (test features which depend upon
-other features *after* having checked the latter), basically you'll
-just have to pay attention to the first failures. BTW, it also makes
-`./testsuite -e' much more useful.
-
-
-* Write tests!
-
-Don't let you be bitten three times by the same dog! When you spent a
-significant amount of time tracking the failure of feature in some
-more primitive problem, immediately write a test for the latter.
-
-If you track down several bugs down to the same origin, write a test
-especially for it.
-
-Of course in both cases, more primitive tests will be run beforehand.
-Write your test and have it failed before your fixing, and succeeding
-after. This usually means having at hand two copies of the source
-tree, one running the test suite to have it fail, and the other to
-have the same testsuite succeed.
-
-
-* Autoconf
-
-** Use of `exit'
-Don't directly `exit 1' or `exit 77', rather use `AC_MSG_ERROR'.
-First of all because when we have to read the test suite logs we are
-happy to know why `configure' exited thanks to the error
-message. Secondly, because `configure' traps the `exit' and pretty
-many shells fail to set $? to 77 when trapping `exit 77'. This
-results in the test suite not being able to check the exit status.
-
-** AC_MSG_ERROR
-Of course, since macro names are forbidden in `configure', if you
-really want to mention the macro name, you'll have to do without
-including `A?_' in the output.

-# ------------------------------------------------
-# Execute a test by performing given shell COMMANDS. These commands

-# STDERR contents.
-#
-# STATUS, STDOUT, and STDERR are not checked if equal to `ignore'.
-#
-# If STDOUT is `expout', then stdout is compared to the content of the file
-# `expout'. Likewise for STDERR and `experr'.
-#
-# If STDOUT is `stdout', then the stdout is left in the file `stdout',
-# likewise for STDERR and `stderr'. Don't do this:
-#
-# AT_CHECK([command >out])
-# # Some checks on `out'
-#
-# do this instead:
-#
-# AT_CHECK([command], [], [stdout])
-# # Some checks on `stdout'
-#
-# This is an unfortunate limitation inherited from Ultrix which will not
-# let you redirect several times the same FD (see the Autoconf documentation).
-# If you use the `AT_CHECK([command >out])' be sure to have the test
-# suite introduces spurious failures.
-#
-# You might wander why not just use `ignore' and directly use stdout and
-# stderr left by the test suite. Firstly because the names of these files
-# is an internal detail, and secondly, because
-#
-# AT_CHECK([command], [], [ignore])
-# AT_CHECK([check stdout])
-#
-# will use `stdout' both in input and output: undefined behavior would
-# certainly result. That's why the test suite will save them in `at-stdout'
-# and `at-stderr', and will provide you with `stdout' and `stderr'.
-#
-# Any line of stderr starting with leading blanks and a `+' are filtered
-# out, since most shells when tracing include subshell traces in stderr.
-# This may cause spurious failures when the test suite is run with `-x'.
-#
-#
-# Implementation Details
-# ----------------------
-# Ideally, we would like to run
-#
-# ( $at_traceon; COMMANDS >at-stdout 2> at-stderr )
-#
-# but we must group COMMANDS as it is not limited to a single command, and
-# then the shells will save the traces in at-stderr. So we have to filter
-# them out when checking stderr, and we must send them into the test suite's
-# stderr to honor -x properly.
-#
-# Limiting COMMANDS to a single command is not good either, since them
-# the user herself would use {} or (), and then we face the same problem.
-#
-# But then, there is no point in running
-#
-# ( $at_traceon { $1 ; } >at-stdout 2>at-stder1 )
-#
-# instead of the simpler
