I have made two installations of gnulib in a project, because I am using
both relocatable-prog and relocatable-lib-lgpl.
I have different modules installed for each, of course.
I just had a problem where my library would not compile, because it was
missing setlocale_null.h. GNULIB_SETLOCALE_NULL was indeed set to 1 by
configure.
The "library gnulib" uses only "locale", which does not depend on
setloacle-null, while the "program gnulib" uses "quote", which does.
I was able to work around this by adding "setlocale" to the library gnulib
(I could not use "quote", as that is a GPL module); but have I done
something wrong here? I can't see how I would fix this in general without
having two configure scripts…

Having two separate configure scripts is undesirable, because that would
increase the total configure time of the package (and people have already
complained about the configure time).
The same problem is seen also in GNU gettext and in GNU poke. I'm fixing it
through the attached patch set.
So, you can now remove 'setlocale' from the modules of your library again.

./stdio.h:846:5: error: #if with no expression
...
The problem is that the macro gl_STDIO_H_REQUIRE_DEFAULTS must only be invoked,
never AC_REQUIREd. Hence all gl_STDIO_MODULE_INDICATOR invocations must also
only be invoked, never AC_REQUIREd. But gl_STDIO_H is automatically AC_REQUIREd,
since it is defined through AC_DEFUN_ONCE.
This patch fixes it.

stdio: Fix build error in some configurations (regression 2021-04-11).
* m4/stdio_h.m4 (gl_STDIO_H): Move gl_STDIO_MODULE_INDICATOR and
gl_MODULE_INDICATOR invocations from here...
* modules/stdio (configure.ac): ... to here.

This deserves to be documented.

Unfortunately this broke getopt-gnu on Solaris 10, because it relies on
this line in modules/unistd:
-e
's/@''GNULIB_UNISTD_H_GETOPT''@/0$(GNULIB_${gl_include_guard_prefix}_UNISTD_H_GETOPT)/g'
\
and substitution went awry in this line, resulting in:
-e
's/@''GNULIB_UNISTD_H_GETOPT''@/0$(GL_GNULIB_GL_UNISTD_H_GETOPT)/g' \
This caused 'make check' to fail because test-getopt-gnu.c was testing
Solaris getopt rather than the Gnulib substitute.
I discovered the problem after updating GNU grep to use the latest
Gnulib, and after someone else's buildbots failed on Solaris 10 with
'grep' and I got notified of their failures:
https://buildfarm.opencsw.org/buildbot/builders/ggrep-solaris10-i386/builds/227
https://buildfarm.opencsw.org/buildbot/builders/ggrep-solaris10-sparc/builds/229
I installed the attached patch to work around the problem. The Python
patch is obviously a hack (and I haven't tested it); suggestions for
improvements are welcome.
I must say that I am starting to reach my limits in debugging this sort
of thing. We have quite a pyramid of hacks here, involving more than
just the usual multilevel combination of make, m4, sh, and sed along
with Git submodules etc., and now also a duplicate Python implementation
that I don't offhand know how to test. And 'gnulib-tool', 'configure'
and 'make check' are so verrryy slow; to find the commit that caused the
problem, I had to run 'git bisect' overnight because my circa-2005
Solaris 10 sparc machine is not as fast as modern machines. This is a
long way from my traditional way of developing where I edited a Makefile
and typed 'make' (and that was already too slow!).
I don't have a solution to this problem, and to some extent am just venting.

Subject: [PATCH] getopt-gnu: port back to Solaris 10
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
* gnulib-tool (func_emit_lib_Makefile_am)
(func_emit_tests_Makefile_am): Don’t substitute things like
$(GNULIB_${gl_include_guard_prefix}_UNISTD_H_GETOPT),
as this mishandles unistd and getopt-gnu, which breaks
‘make check’ on Solaris 10 with getopt-gnu.
* pygnulib/GLEmiter.py (lib_Makefile_am, tests_Makefile_am):
Likewise, albeit hackier since I did not test this and
so went with a trivial hack instead.

Oh, I see:
My "Support several gnulib-tool invocations under the same configure.ac."
commit from 2021-04-11 interfered with the
"Fix conflict between two instantiations of module 'unistd'." commit
from 2011-11-26. Both attempt to do the same thing, just with a different
naming conventions of the substituted variables. And the later commit is in
fact a generalization of the older one. So, instead of adding a workaround,
it is simpler to just rework the older patch.
More precisely, we have 3 times the same situation, between module 'unistd'
and modules
getopt-posix
nonblocking
sigpipe.
The simpler fix is to treat GNULIB_UNISTD_H_GETOPT like
GNULIB_UNISTD_H_NONBLOCKING and GNULIB_UNISTD_H_SIGPIPE.
Done through the patch below. It uses gl_MODULE_INDICATOR_INIT_VARIABLE
conditionally, like done in modules/windows-stat-override.
Tested with a current GNU grep checkout, on Solaris 10/x86_64.

Few people are using the Python-based implementation at this point
(the wget2 people, in particular). If I'm not sure how to keep pygnulib/*
in sync with gnulib-tool, I just leave it out, and leave an entry in
gnulib-tool.py.TODO.
2021-06-13 Bruno Haible <bruno@clisp.org>
Align 2011-11-26 patch to 2021-04-11 patch (regression from 2021-04-11).
Reported by Paul Eggert.
* m4/unistd_h.m4 (gl_UNISTD_H_REQUIRE_DEFAULTS): Also initialize
GNULIB_UNISTD_H_GETOPT variable.
* modules/getopt-posix (configure.ac): Set GNULIB_UNISTD_H_GETOPT
variable.
* modules/unistd (Makefile.am): Rely on ${gl_include_guard_prefix}
processing done by gnulib-tool since 2021-04-11.
* gnulib-tool: Revert last change.
* pygnulib/GLEmiter.py: Likewise.

Yes, these GL_GNULIB_* variables whose name depends on the gnulib-tool
invocation require even more attention and care during problem analysis.
And when developing patches in this area, things are so complex that I
need a written-up plan, because it's impossible to keep the details in
memory.

It's similar on a more modern machine (with GNU grep):
time ./bootstrap 99 sec.
time ./configure 33 sec.
time make 18 sec.
time make check 114 sec.
------------------ --------
TOTAL 264 sec.
Yes, a build cycle of 4 minutes requires a different kind of developing.
In these situations, I typically prepare a script that I can run 100 times,
and turn to other things while the script is running.
Speeding up 'gnulib-tool' would not help much in this situation. It might reduce
the build cycle from 4 minutes to 3 minutes (if it were highly optimized),
but that does not change the basic situation.

It's OK. That's what a mailing list is for :)
