On at least OpenSUSE 12.1, "make install" will install libraries in
the '${prefix}/lib64' directory by default. This is due to the
$CONFIG_SITE set by /etc/profile.d/site.sh, which sets a libdir
that ends in '/lib64' rather than '/lib' if it finds that the compiler
is generating 64-bit code. This behaviour was causing some spurious
failures in our testsuite. Fix them.
* t/posixsubst-libraries.sh: Assume the libraries are installed in
'$(libdir)' rather than in '$(prefix)/lib'.
* t/posixsubst-ltlibraries.sh: Likewise.
* t/posixsubst-scripts.sh: Similarly, don't assume that '$(bindir)',
'$(sbindir)' and '$(libexedir)' always defaults to respectively
'$(prefix)/bin', '$(prefix)/sbin' and '$(prefix)/libexec'.
* t/transform3.test: Likewise.
vala: configure exit with status 77, not 1, if valac version is too old
From a report by Bruno Haible in automake bug#1193. This change should
also automatically avoid spurious testsuite failures with older vala
versions.
* m4/vala.m4 (AM_PROG_VALAC): Exit with status 77, rather than 1, if
the Vala compiler found older than the minimal required version (if
any). This is more consistent with what is done by other macros like
AM_PROG_UPC or AC_PROG_CC.
* NEWS: Update.
* t/vala-headers.sh: Adjust, so that the test is only skipped of the
vala compiler is too old or the required PKG_CHECK_MODULES third-party
macro is not found by aclocal, and not if a generic error happens in
the configure script.
* t/vala-libs.sh: Likewise.

This is a pure refactoring, with no intended functional or semantic
changes. It breaks up an overly-long function in three smaller

automake: refactor pre-processing of makefile fragments
This change will provide the automake script with a new function that
reads in a Makefile fragment *without* performing Automake ad-hoc parsing,
but only the pre-processing step, i.e., removal of '##' comments and
substitution of tokens like '%SUBDIRS%', '%?LIBTOOL%' or '?GENENRIC?'.

Fix that.
* syntax-checks.mk (ams): The definition of this variable was invoking
the 'find' utility in an incorrect way, which resulted into the variable
being empty, thus reducing coverage in some maintainer check and making

When a developer experience one or more failures in the testsuite, a good
workflow is for him to modify its program's sources to fix the bug thus
revealed, run "make recheck" to verify that the change has indeed solved
the testsuite failures previously experienced, and then run "make check"
to verify that the change has not introduced any new failure or regression.
Unfortunately, this apparently natural workflow couldn't have worked until
now, since the Automake-provided 'recheck' target (which didn't depend on
'all') wouldn't have causes the program to be recompiled, and the failed
tests would have thus been run with the older, buggy version of the
program, failing the same way as before.

Avoid some calls to 'framework_failure_', they were only useful when

reasons).

When we (soon) convert the Automake testsuite to a non-recursive
make setup, we'll have to fix the entries of $(TESTS) to be
prepended with the subdirectory they are in; this will increase
the length of $(TESTS), and thus increase the possibility of
exceeding the command-line length limits on some systems (most
notably, MinGW/MSYS). See automake bug#7868 for more information.
Thus we rename the 'tests/' subdirectory to 't/', and each 'x.test'
script in there to 'x.sh'; this way, the $(TESTS) entry 'foo.test'
will become 't/foo.sh', which have the same number of characters.
Those recipes has served its purpose by helping us during the
development of TAP support in Automake, to ensure our TAP driver
didn't have gratuitous incompatibilities with the 'prove' test
runner. But they are now unused, out-of-date and bitrotting. So
it's better to just remove them. We can resurrect them at a later

maint: remove most recursion in automake's own build system
Recursive make-based build systems tend to be slower, more fragile
and less faithful than "flat" ones. See Peter Miller's article
"Recursive Make Considered Harmful" for more a more in-depth
discussion:
<http://miller.emu.id.au/pmiller/books/rmch/>
While in the case of automake this isn't a big problem (given the
small size of its build systems), it still creates occasional
glitches and annoyances.
With this change, the use of recursion in Automake's own build
system is eliminated *but for the testsuite*. Converting that
is a little more tricky, and better left for a later change (or
series of changes).
* tests/instdir-no-empty.test: Also pass proper AM_MAKEFLAGS to
make invocations that might recurse, to ensure the macro definitions
passed from the command line are properly propagated.
Starting from the next major release of Automake (likely 1.13) we
want to start passing the '--tidy' option to texi2dvi and texi2pdf
invocations, so that auxiliary TeX-generated files can be kept
around (thus speeding up rebuilding of DVI and PDF output) without
cluttering the build directory too much.
Since the '--tidy' option was introduced in Texinfo 4.9 (as
documented in the Texinfo distribution's NEWS file), this also
means that Makefiles generated by future Automake versions will
require at least that version of Texinfo (at the time of writing
four years and nine months old).
The users should be warned about the planned behavioral change
and the new version requirement it will entail.
See also automake bug#11146.
* NEWS (Planned Backward Incompatibilities): Add entry about use
of the '--tidy' option and requirement of Texinfo 4.9.
texinfo: don't clutter the builddir when using modern texi2dvi
In modern versions of texi2dvi (at least since version 1.135, which
comes with Texinfo 4.13) the '-o' option does not imply anymore the
'--clean' option. As a consequence, lots of TeX-generated auxiliary
files are now left in the build directory by the 'pdf', 'ps' and
'dvi' rules.
This is especially annoying with non-recursive setups having the
'.texi' files in a subdirectory, as in:
info_TEXINFOS = doc/foo.texi
In this case, the stray auxiliary files are left in the top build
directory (since TeX is run from there). See for example:
* lib/am/texibuild.am: Call 'texi2dvi' and 'texi2pdf' with the
'--clean' option. Update comments accordingly.
* tests/txinfo-noclutter.test: New test.

* HACKING (Working with git): Do not suggest that, to ensure the
bootstrapping process is performed with the latest autotools, the
developer could explicitly pass $AUTOCONF and $AUTOM4TE in the

is a little tricky and quite fragile. Instead, suggest to just
put modern-enough version of the autotools early in PATH.

script should have been used to install m4 files for aclocal. The
comments in this script report that "... A script is needed to do
this because we want to do serial-number checking; newer versions
of macro files should always be preferred".
But the 'acinstall' script has never been really used: for example,
the entry "actually use acinstall program" was removed (unfixed)
from the TODO file in commit 'Release-1-1k-12-g1201405' of
08-12-1996, and the only citation of 'acinstall' in the manual was
removed in commit 'Release-1-1l-37-g128c3d7' of 19-03-1997, and
never added back. In addition, the last non-trivial edit to the
script (that is, besides updates to the copyright notice) dates
back to 1996.
More importantly, now that aclocal supports the ACLOCAL_PATH
environment variable, installing m4 files directly in the
system-wide acdir is discouraged, and better left only to
distros' package managers (which already have their own way to
do so, with which third-party build systems should not directly
meddle).

Since git commit 0c928da9 of 21-06-2010, "tcc: Draft suppoprt for
-MD/-MF options" (sic, with typo in summary line), tcc has supported
automatic dependency generation with a command-line interface
similar to what old (pre-8.0) Intel compilers did. This caused
Automake-generated code for automatic dependency tracking to
recognize tcc dependency style as "icc". However, the format of
the dependency files generated by tcc is apparently different enough
from that of icc to cause spurious failures in the post-processing
operated by our 'depcomp' script on such files.
The failure was exposed with the development version of tcc 0.9.26
(as installed with debian package "tcc 0.9.26~git20120104.83d") by
test case 'depcomp-auto.tap' (available only in the master branch).
* lib/depcomp (icc): Cater to tcc as well. Update comments
accordingly.
* NEWS: Update.
tests: workaround for automatic linker determination and conditionals
See automake bug#11089.
Automake is not very smart in automatically determining the command
to be used to link a program whose source files' languages are
conditionally defined. For example, an input like:
if HAVE_CXX
foo_SOURCES = more.c++
else
foo_SOURCES = less.c
endif
will cause the build rules for 'foo' to *unconditionally* use the
C++ compiler for linking, even when the 'HAVE_CXX' conditional
evaluates to false (which might mean that no C++ compiler is
available).
This behaviour is not really correct, but it's easy enough to work
around, and it's only relevant for fringe use cases (at best). So
let's just test that the workaround really works.
* tests/link_cond.test: New test.
* tests/list-of-tests.mk: Add it.
* THANKS: Update.
info: allow user to inhibit pruning of '${infodir}/dir'
This should have ideally been part of commit 'v1.11-519-g1ec1668'
of 23-11-2011 "info: allow user to inhibit creation/update of
'${infodir}/dir'". Well, better late than never.
* lib/am/texinfos.am (uninstall-info-am): Don't look anymore at the
output of "install-info --version" to decide whether to use it to
update the '${infodir}/dir' or not; instead, honour the environment
variable 'AM_UPDATE_INFO_DIR'. To avoid code duplication with ...
(install-info-am): ... the recipe of this target, move common code
out to ...
(am__can_run_installinfo): ... this new internal variable.
* tests/install-info-dir.test: Enhance.
* doc/automake.texi (Texinfo): Update.
* NEWS: Likewise.

vala tests: fix spurious failures with older valac (<= 0.7.2)
See automake bug#11093.
The Vala compiler before the 0.7.3 release does not support the
'--profile' option. But some of our tests were relying on it, so
skip those tests if the detected Vala compiler is too old.
* tests/vala-vpath.test, tests/vala-mix.test, tests/vala-mix2.test
(configure.in): Require vala version >= 0.7.3 in AM_PROG_VALAC call.
Reported by Panther Martin in automake bug#10848. See also
automake bug#11093.
* tests/conffile-leading-dot.test: Add a proper '$sleep' invocation,
to avoid spurious failures on fast systems without sub-second
timestamp resolutions. Add other minor related and unrelated
improvements and fixlets since we are at it.
* tests/conffile-leading-dot.test: Relax grepping of 'config.status'
stderr, to cater for older autoconf. Issue revealed by a failure
with autoconf 2.63 on Cygwin 1.5.25. See also automake bug#11093.
We don't have to make creation of $(foodir) conditional when
foo_PRIMARY is conditionally defined; that has been solved in
a more sweeping way by commit v1.11-759-g368f1c4 of March 18,
which solved bug#11030 and bug#10997.
The "check" target already depends on the "all" target.
Remove comment "investigate problems with conditionally defined
libraries"; it is aimed at automake 1.5 (!) and too terse and old
to be useful now.
Remove the 12 years old suggestion that "distcheck should make sure
that each file that uses _() is listed in POTFILES.in"; this is
handled by gnulib-provided syntax check 'sc_po_check' already today.
Don't tell to "Run automake before libtool"; automake does not
automatically run libtool anymore today.
Remove hint about the possibility to "rewrite automake in guile" or
"add a GUI": we are not going to do so.
The automatic de-ANSI-fication feature has already been remove, so
no need to suggest its potential removal in the future.
Remove reference to a prospective "cvs" option that could add some
cvs-specific rules. First of all, CVS is falling out of use today.
Secondly, and most to the point, instead of guessing which VCS
is going to be most popular and try to hack support for it into
automake, we should leave it to developer-specific makefile
fragments offered by projects like Gnulib to provide such rules
(they are already doing so with succcess).
About DOS support: it should actually be dropped, not extended.
Add link about Karl Berry's proposal of preferring HTML over Info
documentation installed in the local system:
<http://lists.gnu.org/archive/html/texinfo-devel/2012-03/msg00018.html>
Remove items about "beautification" of output Makefile.in; they
are pretty obvious, and mostly noise (after all, everybody prefers
clean output where possible). Leave it to any developer doing
future refactorings to find out low-hanging and/or high-impact
optimizations and beatifications of the generated Makefiles.
Remove item about internationalization: we're not going to
implement it.
Remove an item explicitly marked as "not that it matters".
The order of files in a distribution tarball does not really
matter, nobody has ever complained about it, so do not worry
about it.
Remove the suggestions about allowing hierarchy of dirs to share
one aclocal.m4 and about printing full file name of Makefile.am
or configure.in when giving error, in order to help very large
trees: nobody has ever complained about the current behaviours,
so no real need to change them.
fixup: bootstrapping issues with 'list-of-tests.mk'
* tests/list-of-tests.mk: This file is expected to be executed
directly with make from the bootstrap script, so we can't use
Automake '##' comments after line continuations.

maint: move definition of XFAIL_TESTS near TESTS
Actually, after the trivial merge conflicts have been solved, what
this change actually does is moving the definition of XFAIL_TESTS
near that of handwritten_TESTS. But the rationale is the same of
that of commit 'v1.11-761-gabf40ce' (being merged here), and still
works, so all is good.
