[PATCH] general: deprecate 'configure.in' as autoconf input

Stefano Lattarini — 2012-05-19T08:25:16

It has been years since that has been deprecated in the documentation,
in favour of 'configure.ac':

  Previous versions of Autoconf promoted the name configure.in, which
  is somewhat ambiguous (the tool needed to process 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.

It's now time to start giving runtime warning about the use of
'configure.in', so that support for it can be removed in future
versions of autoconf/automake.

* lib/Autom4te/Configure_ac.pm: Issue a warning in the 'obsolete'
category if 'configure.in' is detected.  Since this module is synced
from Automake, this change is to be backported there (and will be
soon).
* doc/autoconf.texi: Update.
* tests/tools.at: Adjust to avoid spurious failures.

[PATCH] Improve cross-compilation guesses for glibc system hosts.

Bruno Haible — 2012-05-02T21:02:49

Hi,

Paul and Eric suggested that improving the cross-compilation guesses
for targets that are glibc systems would be welcome here [1][2], so here
is a proposed patch.

This patch modifies the cross-compilation behaviour of
  AC_FUNC_CHOWN
  AC_FUNC_GETGROUPS
  AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK
  AC_FUNC_MALLOC
  AC_FUNC_MMAP
  AC_FUNC_REALLOC
  AC_FUNC_STRCOLL
so that when the target is a glibc system (or, in case of AC_FUNC_MALLOC
and AC_FUNC_REALLOC, any known "good" Unix system), the guess is
"yes it works" rather than "guessing no".

This is important because some of these macros are used in Gnulib, and
in case of "guessing no" Gnulib provides extra workaround code, and
  1) Generally, when targetting embedded systems, code size should be
     minimized,
  2) In [3], unnecessary workaround code will look like a Glibc bug.

This patch also changes the configure output to "guessing yes" or
"guessing no" in a case where the ac_cv_* variable is undocumented.

[PATCH] maint: drop bz2 tarball

Eric Blake — 2012-04-25T02:46:27

At 2.68b, I asked whether anyone would miss .gz and .bz2 formats.
Consensus was overwhelming that .gz still holds a place in people's
hearts, in spite of .xz compressing to smaller files, but no one
was able to make a convincing argument for .bz2.

* configure.ac (AM_INIT_AUTOMAKE): Drop bzip2; xz wins hands down.

[PATCH] maint: resync files from upstream

Eric Blake — 2012-04-24T23:38:03

The files in lib/Autom4te/ are intentionally not synced at this
point, since this recent Automake patch:
https://lists.gnu.org/archive/html/automake-patches/2012-03/msg00111.html

was buggy regarding '-' as stdout, and also exposes some latent
bugs in autoconf where we use raw 'open' instead of XFile::open.

* build-aux/announce-gen: Resync via 'make fetch'.
* build-aux/config.sub: Likewise.
* build-aux/git-version-gen: Likewise.
* build-aux/gnupload: Likewise.
* build-aux/move-if-change: Likewise.
* build-aux/texinfo.tex: Likewise.
* doc/standards.texi: Likewise.
* maint.mk: Likewise.
---

Ultimately, I want to fix the bugs in XFile.pm, and in autoconf's
improper use of raw 'open', but that can wait until after autoconf
2.69 and automake 1.12, as it may prove a bit disruptive.

[PATCH] remove warning for --host without --build

Bruno Haible — 2012-04-22T17:42:24

Hi,

On bi-arch systems (such as x86 / x86_64) it is often necessary to pass
the --host option together with an appropriate value for CC. But this
triggers a warning:

$ ./configure --host=i686-pc-linux-gnu CC="gcc -m32 -march=i586"
configure: WARNING: if you wanted to set the --build type, don't use --host.
    If a cross compiler is detected then cross compile mode will be used
...

This warning was introduced on 2000-06-30, in commit
<http://git.savannah.gnu.org/gitweb/?p=autoconf.git;a=commitdiff;h=cb2e761b8e1181f97e8e09d85526bd22078433db>
with the remark "Re-enable the old behavior of --host and --build."

This warning was meant to warn users about a changed semantics of
--build and --host. This change is now 12 years in the past; users
have had enough time to learn it. I therefore suggest to remove the
warning.

I've done lots of cross and bi-arch compilations in the last 10 years,
all with --host and without --build, and have never observed a problem
with it, except for the warning. Simply relying on

[patch] lib/autoconf/specific.m4: turn AC_ISC_POSIX into a NOP

Adrian Bunk — 2012-04-07T20:09:07

The platform that needed it saw it's last release in 1998,
is completely unsupported since 2006, and it was already
documented that new programs need not use AC_ISC_POSIX.

The main objective of this change is that without it autoupdate
turned AC_ISC_POSIX into AC_SEARCH_LIBS([strerror],[cposix])
in configure.ac, keeping this zombie alive forever.

I ran my little spell-checking program and pushed the following
as (I hope) obvious.  I took the liberty of replacing "facultative"
with "optional", since I hadn't a clue what "facultative" meant
until I looked it up and it does seem to be a term that's used
in biology rather than in computing.

[PATCH] m4sh: make AS_EXECUTABLE_P public

Eric Blake — 2012-02-25T05:11:58

In the process of making it public, factor it into a reusable
function.  This makes constructs like AC_CHECK_PROGRAM smaller,
as well as making libtool's naughty use of $as_executable_p safer.

* lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Add a shell function.
(AS_EXECUTABLE_P): Forward to shell function.
* doc/autoconf.texi (Common Shell Constructs): Document it.
* NEWS: Mention this.

Any thoughts about this as a followup?  I will probably apply
it prior to cutting the pre-2.69 beta later this weekend.
