Arsen,

Unfortunately this broke bootstrap on AIX.

I had not seen this series of patches.

I've added Bruno to CC as the libintl maintainer, to keep him in the
loop.  Could you provide some extra information w.r.t. the failure mode?

I'll try to investigate ASAP.

In the meanwhile, does disabling NLS etc work?

Thanks in advance, have a lovely night.

--disable-nls gets past the breakage, but GCC does not build for me on AIX
with NLS enabled.

A change in dependencies for GCC should have been announced and more widely
socialized in the GCC development mailing list, not just GCC patches
mailing list.

I have tried both the AIX Open Source libiconv and libgettext package, and
the ones that I previously built.  Both fail because GCC configure decides
to disable NLS, despite being requested, while libcpp is satisfied, so
tools in the gcc subdirectory don't link against libiconv and the build
fails.  With the included gettext, I was able to rely on a self-consistent
solution.

The current gettext-0.22.3 fails to build for me on AIX.

libcpp configure believes that NLS functions on AIX, but gcc configure
fails in its tests of gettext functionality, which leads to an inconsistent
configuration and build breakage.

Thanks, David

Here are some hints to get a successful build of GNU gettext on AIX:

1. Set the recommended environment variables before running configure:
   https://gitlab.com/ghwiki/gnow-how/-/wikis/Platforms/Configuration

   Namely:
   * for a 32-bit build with gcc:
     CC=gcc
     CXX=g++
     CPPFLAGS="-I$PREFIX/include"
     LDFLAGS="-L$PREFIX/lib"
     unset AR NM
   * for a 32-bit build with xlc:
     CC="xlc -qthreaded -qtls"
     CXX="xlC -qthreaded -qtls"
     CPPFLAGS="-I$PREFIX/include"
     LDFLAGS="-L$PREFIX/lib"
     unset AR NM
   * for a 64-bit build with gcc:
     CC="gcc -maix64"
     CXX="g++ -maix64"
     CPPFLAGS="-I$PREFIX/include"
     LDFLAGS="-L$PREFIX/lib"
     AR="ar -X 64"; NM="nm -X 64 -B"
   * for a 64-bit build with xlc:
     CC="xlc -q64 -qthreaded -qtls"
     CXX="xlC -q64 -qthreaded -qtls"
     CPPFLAGS="-I$PREFIX/include"
     LDFLAGS="-L$PREFIX/lib"
     AR="ar -X 64"; NM="nm -X 64 -B"

   where $PREFIX is the value that you pass to the --prefix configure option.

   Rationale: you can run into all sorts of problems if you choose compiler
   options at random and haven't experience with compiler options on that
   platform.

2. Don't use ibm-clang.

   Rationale: It's broken.

3. Don't use -Wall with gcc 10.3.

   Rationale: If you specify -Wall, gettext's configure adds -fanalyzer, which
   has excessive memory requirements in gcc 10.x. In particular, on AIX, it
   makes cc1 crash while compiling regex.c after it has consumed 1 GiB of RAM.

4. Avoid using a --prefix that contains earlier installations of the same
   package.

   Rationale: Because the AIX linker hardcodes directory names in shared
   libraries, GNU libtool has a peculiar configuration on AIX. It ends up
   mixing the in-build-tree libraries with the libraries in the install
   locations, leading to all sorts of errors.

   If you really need to use a --prefix that contains an earlier
   installation of the same package:
     - Either use --disable-shared and remove libgettextlib.a and
       libgettextsrc.a from $PREFIX/lib before starting the build.
     - Or use a mix of "make -k", "make -k install" and ad-hoc workarounds
       that cannot be described in a general way.

There seem to be two problems, both related to the include files of
your compiler:

  - The configure test "checking for intmax_t..." must have found the
    answer "no". But on a modern system, <stdint.h> should be defining
    intmax_t already.

  - This configure test that tries to find the getpeername declaration,
    but cannot find it (maybe because of the first problem?):

================================================================================
         for arg2 in "struct sockaddr" void; do
           for t in int size_t "unsigned int" "long int" "unsigned long int"; do
             cat confdefs.h - <<_ACEOF >conftest.$ac_ext
/* end confdefs.h.  */
#include <sys/types.h>
                   #include <sys/socket.h>

                   int getpeername (int, $arg2 *, $t *);
int
main (void)
{
$t len;
                  getpeername (0, 0, &len);
  ;
  return 0;
}
_ACEOF
if ac_fn_c_try_compile "$LINENO"
then :
  gl_cv_socklen_t_equiv="$t"
fi
================================================================================

I would concentrate on the first problem. If you don't get it fixed, then I'd
suggest to try 'gcc' from the AIX Toolbox [1] or 'xlc' (as an IBM product)
instead of 'gcc' (that looks like you built it yourself).

Bruno,

I am using my own install of GCC for a reason.  The build of GCC works for
everything else, including bootstrap of GCC, GDB, GMP, etc.  The only
problem is gettext.

Thanks, David

I have built GNU gettext 0.22.3 in various configurations on the AIX 7.1
and 7.3 machines in the compilefarm, and haven't encountered issues with
'max_align_t' nor with 'getpeername'. So, from my point of view, GNU gettext
works fine on AIX with gcc and xlc (but not ibm-clang, which I haven't
tested).

You will surely understand that I cannot test a release against a compiler
that exists only on your hard disk.

The hint I gave you, based on the partial logs that you provided, is to
look at the configure test for intmax_t first.

Re: building GNU gettext on AIX

[David Edelsohn]

[-- Attachment #1: Type: text/plain, Size: 1712 bytes --]

Bruno,

I have been able to tweak the environment and build gettext and libintl.
With the updated libintl and environment, GCC reliably does not use NLS.

The issue is that libintl utilizes pthreads.  AIX does not provide no-op
pthread stubs in libc.  pthreads is an explicit multilib on AIX.

It is great that gettext and libintl can be built thread-safe, but GCC
(cc1, gcov, etc.) are not pthreads applications and are not built with
pthreads.  Because libintl defaults to pthreads enabled, NLS cannot
function in GCC on AIX by default.  The GCC included gettext was built in
the default for GCC libraries, which was not pthreads enabled.

I can rebuild libintl with --disable-pthreads and I will see if that works,
but the default, distributed libintl library will not allow GCC to be built
with NLS enabled.  And, no, GCC on AIX should not be forced to build with
pthreads.

This is a regression in NLS support in GCC.

Thanks, David

I configured gettext with --disable-pthreads and libintl.a still contains
references to pthread_mutex_lock and pthread_mutex_unlock, which causes NLS
configure to fail on AIX.

How can this be corrected?

The issue appears to be that intl/gnulib-lib/{mbrtowc.c,setlocale_null.c}
include pthread.h based on HAVE_PTHREAD_API, which is defined as 1 in
intl/config.h build directory despite requesting --disable-pthreads.

Thanks, David

Re: building GNU gettext on AIX

[-- Attachment #1: Type: text/plain, Size: 3904 bytes --]

I manually commented out HAVE_PTHREAD_API from config.h and produced a
libintl.a without references to pthreads.  Configuring GCC with that custom
libintl.a enables NLS.  I now am building GCC with NLS and we will see how
well it functions.

gettext depends on pthreads by default and the versions distributed.

Good finding!

Commenting out HAVE_PTHREAD_API from config.h is also what makes the
option --enable-threads=isoc work as expected on AIX 7.3.

I reconfigured and built gettext with --enable-threads=isoc .  libintl.a
still contains references to pthread_mutex and friends:

$ nm -BCpg libintl.a  | grep pthread

         - U __n_pthreads

         - U .pthread_mutex_lock

         - U .pthread_mutex_unlock

         - U .pthread_mutex_lock

         - U .pthread_mutex_unlock
         - U __n_pthreads

from files mbrtowc, setlocale_null, and vasnwprintf.

I tested on an AIX 7.2.5 system and confirmed that libc does provide the
mtx_ symbols:

$ nm -BCpg libc.a | grep mtx_

         0 T .mtx_timedlock

       160 T .mtx_unlock

       256 T .mtx_trylock

       416 T .mtx_lock

       512 T .mtx_init

       736 T .mtx_destroy

        80 D mtx_timedlock

        92 D mtx_unlock

       104 D mtx_trylock

       116 D mtx_lock

       128 D mtx_init

       140 D mtx_destroy


Were you suggesting that --enable-threads=isoc would work now or that it
would require further changes for a future release?


At the moment, configuring gettext with --disable-threads and manually
modifying config.h is the only method that produces

libintl.a without references to pthreads allowing GCC to build on AIX with
NLS enabled.


Thanks, David

Re: building GNU gettext on AIX

[Bruno Haible]

Hi David,

> the default, distributed libintl library will not allow GCC to be built
> with NLS enabled.

The problem is this configure test from gettext.m4

  checking for GNU gettext in libintl... no

It should say

  checking for GNU gettext in libintl... yes

I reproduce it with simple hello-world package, outside GCC.

It tests whether a program that uses gettext() can be linked with
  -lintl -liconv
But now, on AIX, it needs to test whether such a program can be linked with
  -lintl -liconv -lpthread

> Were you suggesting that --enable-threads=isoc would work now or that it
> would require further changes for a future release?

It requires a change, effectively to do as if HAVE_PTHREAD_API is undefined
if --enable-threads=isoc was provided.

I can prepare a new gettext release that has both issues fixed:
  - gettext.m4 that fixes the configure test and sets the variable LIBINTL
    to "-Lsome/libdir -lintl -liconv -lpthread",
  - mbrtowc.o and setlocale*.o that use mtx_* locks instead of pthread_*
    mutexes when requested.

But you then need to make up your mind w.r.t. what I wrote in the earlier
mail.

  * GCC can pass --enable-threads=isoc, to avoid the libpthread dependency
    on AIX ≥ 7.2.

  * Or GCC can (continue to?) use the variable LIBINTL. This will work on
    AIX 7.1 as well but the programs will then be linked against libpthread.
    One additional library.
    $ ldd gcc
    /opt/freeware/bin/gcc needs:
         /usr/lib/libc.a(shr.o)
         /opt/freeware/lib/libiconv.a(libiconv.so.2)
         /usr/lib/libc.a(_shr.o)
         /unix
         /usr/lib/libcrypt.a(shr.o)
         /opt/freeware/lib/libgcc_s.a(shr.o)
    libpthread.a will be added to this list.

    ibm-clang links against libpthread.a as well:
    $ ldd /opt/IBM/openxlC/17.1.1/bin/.ibm-clang.orig
    /opt/IBM/openxlC/17.1.1/bin/.ibm-clang.orig needs:

Hmm, would that option work everywhere, though?  Or would we have to
wire up configury to detect which flag to use?  If so, what would it
look like.

>   * Or GCC can (continue to?) use the variable LIBINTL. This will work on

If you mean the one generated by gettext.m4/uninstalled-config.sh, it is
utilized today:

LIBS = @LIBS@ libcommon.a $(CPPLIB) $(LIBINTL) $(LIBICONV) $(LIBBACKTRACE) \
	$(LIBIBERTY) $(LIBDECNUMBER) $(HOST_LIBS)

(from gcc/Makefile.in)

I'd highly recommend the in-tree gettext to be built with thread
support _disabled_,
only a static library built and never installed (but linked statically
into the host
binaries).

So if --disable-threads (or how it is called) does not work you need
to fix _that_.
Likewise if --disable-shared doesn't work correctly on all platforms
you have to fix
that as well.

That seems like the best choice to me too (and I'm testing a patch that

--enable-threads=isoc should only be used where needed, i.e. on AIX 7.2
or higher. Yes, this needs a configure test.

As long as this static libintl.a gets never installed (but linked statically
into the host binaries), that's perfectly fine.

It only needs a fixed gettext.m4, to deal with the bug that David Edelsohn
noticed on AIX (but that exists on macOS as well). [1]

That should always work for us, then (the only case in which the GCC
build system sets up flags for gettext is when building it in-tree, in
which case we already want a --disable-shared build).

If that library gets installed, then, so far, it is unintentional.  I'll
check that (as well as the docs targets that Eric Gallager mentioned on
IRC) tonight.

I have reached out to the AIX Open Source Tools team for their
perspective.  Normally GCC and other
FOSS packages have not based their support for OS versions on official
vendor support lifecycles,
within reason.  In fact, many users have appreciated longer duration
support.

My builds of GCC only rely on AIX libc.  All other libraries are statically

I have asked the IBM Clang team why ibm-clang depends on libpthreads.

One option is to add -lpthreads to the link line, even if the tools are not
built
thread-safe.  Only the intl support would invoke the extraneous overhead.
The downside is that other pthreads dependencies could sneak in.

Thanks, David

The reason is that
  - For a library, it is a normal expectation nowadays that it is
    multithread-safe.
  - Making a library multithread-safe (without major hacks) means to do
    locking or to call pthread_once / call_once in some places.
  - The ISO C 11 threading functions in libc have some drawbacks compared
    to the pthread functions. [1] So most developer prefer to rely on the
    POSIX threads API.
  - Since AIX does not have the POSIX mutex functions in libc and does not
    support weak symbols like in ELF, this means a dependency to
    pthread_mutex_lock or pthread_once.
  - Accordingly, in the list of libraries above, 3 libraries need pthread*
    symbols:

$ nm -X 64 /usr/lib/libc++abi.a | grep ' U ' | grep pthread_mutex
pthread_mutex_lock   U           -
pthread_mutex_unlock U           -
$ nm -X 64 /usr/lib/libc++.a | grep ' U ' | grep pthread_mutex
pthread_mutex_destroy U           -
pthread_mutex_init   U           -
pthread_mutex_lock   U           -
pthread_mutex_trylock U           -
pthread_mutex_unlock U           -
pthread_mutexattr_destroy U           -
pthread_mutexattr_init U           -
pthread_mutexattr_settype U           -
$ nm -X 64 /usr/opt/zlibNX/lib/libz.a | grep ' U ' | grep pthread_mutex
pthread_mutex_destroy U           -
pthread_mutex_init   U           -
pthread_mutex_lock   U           -
pthread_mutex_unlock U           -

There are ibm_clang and ibm_clang_r (previous xlc and xlc_r) to compile
with and without thread safe.   If IBM Clang team
chose to only provide a thread safe version of libc++, okay, but that
doesn't seem like a fundamental requirement.
zlibNX is another can of worms.

The latest issue is that a few files in gettext ignore --disable-pthreads
and creates a dependency on pthread_mutex.

GNU gettext does not have an option '--disable-pthreads'. Instead, it has
options

  --enable-threads={isoc|posix|isoc+posix|windows}
                          specify multithreading API

  --disable-threads       build without multithread safety

Yup, I confirm that the dependency comes from these two object files.

Will the next GCC release support AIX 7.1.x ? Recall that AIX 7.1 went
end-of-life on 2023-04-30 [1]

  * If no, then the simple solution would be to pass the configure option
      --enable-threads=isoc
    This should not introduce a link dependency, because the mtx_lock,
    mtx_unlock, and mtx_init functions are in libc in AIX ≥ 7.2. Currently it
    does not work (it still uses pthread_mutex_lock and pthread_mutex_unlock
    despite --enable-threads=isoc). But I could make this work and release
    a gettext 0.22.4 with the fix.

  * If yes, then the question is how distributors will in general package
    libintl on AIX. If it's installed in public locations (such as in
    /opt/freeware/{lib,lib64}/libintl.a on gcc119.fsffrance.org), then we
    have a problem: It may cause undefined behaviour in multithreaded
    packages that use GNU libintl.
    If you can guarantee that it will be installed in GCC-private directories
    (and outside the path where GCC looks for libraries to link with!) then
    it would be OK to install such a non-thread-safe libintl.
    But if you cannot guarantee that, we are in trouble.

    How do other library vendors handle this issue on AIX? Do they ship two
    libraries, one MT-safe and one not? Under different names? Or in different
    library search paths?

The in-tree configuration already passes --disable-shared, so I imagine
passing --disable-threads would be OK too, for the case that it is
utilized.  (relevant for the latter case: GCC-private build of libintl)

Yeah, but this affects only those people who use the in-tree build of
the libraries.

The problem for distributors remains the same: They have a strong tendency
of building libraries indepently, with --enable-shared (so that they can
easily apply fixes without rebuilding the world). These distributors on AIX
would notice that the GCC configuration attempts to link with "-lintl"
but not with "-lintl -pthread" and thus the configuration detects that NLS
is not usable.

Arsen: Where in the GCC tree is this part of the GCC configuration? Is it
in some configure.ac owned by GCC, or does it come from gettext.m4 ?

See Makefile.def.  It specifies a host-gettext module that has the extra
flags set.

If the in-tree configuration is used, then the uninstalled-config.sh
gettext generates is used.  See config/gettext-sister.m4.

gettext.m4 is unaltered, but it is essentially only used when the
gettext in-tree source is not present (because, otherwise,
gettext-runtime generates uninstalled-config.sh even if it builds
nothing)

Hope that answers it.

Alas, this approach does not help reducing the dependency towards libpthreads.
On AIX, pthread_mutex_t and mtx_t are the same type. Thus code like this
===================================================
#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>
#include <threads.h>

pthread_mutex_t lock1 = PTHREAD_MUTEX_INITIALIZER;

int main ()
{
  if (mtx_lock (&lock1) != thrd_success)
    abort ();

  if (mtx_unlock (&lock1) != thrd_success)
    abort ();
}
===================================================
compiles and runs fine. But the library dependencies still contain libpthreads.
This is in 32-bit mode:

$ ldd a.out
a.out needs:
         /usr/lib/libc.a(shr.o)
         /usr/lib/libc.a(cthread.o)
         /usr/lib/libc.a(_shr.o)
         /unix
         /usr/lib/libcrypt.a(shr.o)
         /usr/lib/libpthreads.a(shr_xpg5.o)
         /usr/lib/libpthreads.a(_shr_xpg5.o)
         /usr/lib/libpthreads.a(shr_comm.o)

and this in 64-bit mode:

$ ldd a.out 
a.out needs:
         /usr/lib/libc.a(shr_64.o)
         /usr/lib/libc.a(cthread_64.o)
         /usr/lib/libc.a(_shr_64.o)
         /unix
         /usr/lib/libcrypt.a(shr_64.o)
         /usr/lib/libpthreads.a(shr_xpg5_64.o)
         /usr/lib/libpthreads.a(_shr_xpg5_64.o)

Apparently the mtx_* functions are provided by
  /usr/lib/libc.a(cthread_64.o)
and this one depends on
  /usr/lib/libpthreads.a(shr_xpg5_64.o)
  /usr/lib/libpthreads.a(_shr_xpg5_64.o)

So, there can be only three ways to build GCC on AIX:

  - With --disable-nls. No i18n, no libpthreads dependency.
  - With --enable-nls, linked against a libintl created in the build
    tree with --disable-shared --disable-threads (requires gettext ≥ 0.22.4).
    Has i18n, but no libpthreads dependency.
  - With --enable-nls, linked against a public libintl. Depends on libpthreads.

That is interesting.  They should be using the same checks.  I've
checked trunk and regenerated files on it, and saw no significant diff
(some whitespace changes only).  Could you post the config.log of both?

I've never used AIX.  Can I reproduce this on one of the cfarm machines
to poke around?  I've tried cfarm119, but that one lacked git, and I
haven't poked around much further due to time constraints.

TIA, sorry about the inconvenience.  Have a lovely day.

You did not regenerate config.in.  But I've regenerated it in r14-5434
anyway.

The related changes:

I don't know if they are related to the issue on AIX though.

The AIX system in the Compile Farm has a complete complement of Open Source
software installed.

Please ensure that /opt/freeware/bin is in your path.  Also, the GCC Wiki
Compile Farm page has build tips that include AIX

https://gcc.gnu.org/wiki/CompileFarm#Services_and_software_installed_on_farm_machines

that recommended --with-included-gettext configuration option.

Thanks, David

Thanks, that got me further.

This flag should still exist and operate the same if gettext is present
in tree.  I've cloned gcc and downloaded prerequisites (via
contrib/download_prerequisites) and I am trying to configure it now.

The build failed.  After gettext/gmp/... (in-tree hostlibs) get built
and added to library paths, further GCC processes fail to run:

configure:3305: gcc -g  -static-libstdc++ -static-libgcc -Wl,-bbigtoc conftest.c  >&5
Could not load program /opt/freeware/libexec/gcc/powerpc-ibm-aix7.3.0.0/10/cc1:
        Dependent module /home/arsen/build/./gmp/.libs/libgmp.a(libgmp.so.10) could not be loaded.
        Member libgmp.so.10 is not found in archive 

This seems odd.  I am not sure what compels the RTDL (?) to look up .sos
in archives, or how it knows about these archives..  I suspect it's
getting tripped by something in HOST_EXPORTS.

Don't build with the dependent libraries in tree.  Don't build the
dependent libraries as shared libraries. The libraries are already built
and in /opt/cfarm, as mentioned in the Compile Farm wiki.

AIX is not Solaris and not Linux.  It doesn't use ELF.  AIX shared
libraries *ARE* shared object files in archives.  Shared object versioning
is handled by multiple objects in the same archive.

Hmm, I see.  I removed all the deps but gettext from the tree.

This leaves gettext-runtime fulfilling the previous role of intl/.

However, I'm confused about how this worked before, in that case, since,
IIRC, intl also produced libraries and was also put into host exports.

Leaving gettext in tree produces:

Could not load program gawk:
        Dependent module /home/arsen/build/./gettext/intl/.libs/libintl.a(libintl.so.8) could not be loaded.
        Member libintl.so.8 is not found in archive 

I'll try to see why intl/ didn't cause the same issue soon.

Thanks, have a lovely evening.

The previous version of "intl" was built as a static library.  Configure in
the older package had the option --enable-host-shared,
which I did not use.  Based on the failure message, the in-tree gettext
seems to be built as a shared library.  If you explicitly
pass --disable-shared to the in-tree configure, you may get farther.  I'm
currently using --disable-shared --disable-threads.
As we have discussed, the current gettext will retain some references to
pthreads despite the configure option.

Sure, but my patch does insert --disable-shared:

--8<---------------cut here---------------start------------->8---
host_modules= { module= gettext; bootstrap=true; no_install=true;
                module_srcdir= "gettext/gettext-runtime";
		// We always build gettext with pic, because some packages (e.g. gdbserver)
		// need it in some configuratons, which is determined via nontrivial tests.
		// Always enabling pic seems to make sense for something tied to
		// user-facing output.
                extra_configure_flags='--disable-shared --disable-java --disable-csharp --with-pic';
                lib_path=intl/.libs; };
--8<---------------cut here---------------end--------------->8---

... and it is applied:

--8<---------------cut here---------------start------------->8---
-bash-5.1$ ./config.status --config
--srcdir=../../gcc/gettext/gettext-runtime --cache-file=./config.cache
  --disable-werror --with-gmp=/opt/cfarm

--8<---------------cut here---------------end--------------->8---

I'm unsure how to tell what the produced binaries are w.r.t static or
shared, but I only see .o files inside intl/.libs/libintl.a, while I see
a .so.1 in (e.g.) /lib/libz.a, hinting at it not being shared (?)

I do see that the build system adds intl to the LD_LIBRARY_PATH.

I will be testing dropping lib_path from the module definition above.
It might be superflous (I think it is only used for LD_LIBRARY_PATH, for
when the libs built by the build system are shared - which they never
are for in-tree gettext).  I'll take the shot to add --disable-threads,
too, for this test.

An AIX shared library created by libtool will look like
libfoo.a[libfoo.so.N], where N is the package major version number.
Normally with one file.

An AIX static library will look like libfoo.a[a.o, b.o, c.o]
with multiple object files.

An AIX archive can contain a combination of shared objects and
normal object files.

AIX normally uses the convention shr.o or shr_64.o for the name
of the shared object file.  Hint, hint, an AIX archive can contain
both 32 bit and 64 bit object files or shared objects.

I don't know why the gettext build system would create
/home/arsen/build/./gettext/intl/.libs/libintl.a(libintl.so.8)
if --disable-shared was requested.  That clearly is using the
naming of a libtool AIX shared object and failing due to
the missing shared object.  Although in this case, the problem
seems to be the shared library load path.  AIX uses LIBPATH,
not LD_LIBRARY_PATH.

Also, for me, the out of tree path was

gettext/gettext-runtime/intl/.libs

Is your search path missing a level?

It doesn't create libintl.a with a libintl.so.8 inside of it.  The
libintl.a contains a bunch of objects, as I'd expect of a static
library:

--8<---------------cut here---------------start------------->8---
-bash-5.1$ ar -t gettext/intl/.libs/libintl.a  | grep libintl
-bash-5.1$ ar -t gettext/intl/.libs/libintl.a    
bindtextdom.o
dcgettext.o
...
--8<---------------cut here---------------end--------------->8---

No, the above is generated by the GCC build system and builds
gettext-runtime directly (per Brunos recommendation a while ago) as it
is replacing intl/ of similar functionality.

I'm currently building GCC with libintl with the threads hack you
mentioned applied (as I got undefined references to the pthread
functions you discovered).  I suspect that, bar this issue (which, IIUC,
Bruno will fix in a new release?) the patch above will fix the issues
you've encountered on AIX (note that if you want to use gettext in-tree,
you'd still have to fetch gettext into the tree).

Maybe we should provide a download-prerequisite-y script that skips
everything but GNU gettext, to retain same behavior?

Have a lovely day.

I'm concerned that the gettext fixes are working around AIX support for

--enabled-threads=isoc use of mtx_* is a workaround, but it's still not
allowing users to truly disable threads.

--disable-threads currently does not completely disable threads.  Bruno is
suggesting --enable-threads=isoc that relies on mtx mutex functions in libc.

Yes, GCC should configure the in tree gettext with --disable-threads, but
that configure option is not completely effective and does not produce a
build without threads references.

Even with --enable-threads=isoc in place of --disable-threads, I get a

Unfortunately, as said in the other mail today, relying only on mtx_* functions
did not drop the dependency towards libpthreads.

So, I've made a new release gettext-0.22.4, that includes only these changes:

  - AM_GNU_GETTEXT now recognizes a statically built libintl on macOS and AIX.

  - Passing --disable-threads now builds a libintl that, on AIX, does not
    need -lpthread.

  - Other build fixes on AIX.

Now it is effective. But you (Arsen) should state in the documentation
(gcc/doc/install.texi) that for --disable-threads to have this effect,
one needs gettext version 0.22.4 or newer.

Not in gcc/doc/install.texi, but elsewhere. This topic is not relevant to
the average user who installs GCC from a tarball or from a git checkout.
Only to GCC hackers who have peculiar needs.

That still is documented in install.texi really.
https://gcc.gnu.org/install/specific.html#x-ibm-aix is generated from
that and it talks about other options dealing with NLS there.
Which seems like that part might need to be updated too.

So the question is do we want to change GCC on AIX to always link against
pthreads so that GCC can build with default, external builds of gettext
libintl.  I don't see a path for i18n support to work for GCC on AIX
without that unfortunate change.

Well, if detectable by the build system for, I imagine we could avoid
pthread if gettext is built without them.  With the 'private' gettext
build, we should never need threads anyway.

P.S: Building on AIX is nearly successful.  gettext-0.22.4 builds, twice
or even thrice, but ends up producing a bootstrap comparison fail:

  make[3]: Leaving directory '/home/arsen/build'
  Comparing stages 2 and 3
  Bootstrap comparison failure!
  gettext/libasprintf/autosprintf.o differs
  make[2]: *** [Makefile:23435: compare] Error 1

I am unsure what this symbol is.  It does not appear in the stripped

_GLOBAL__F_xxx is the EH frame data.

It's using the filename with full path for the unique name, which is why it
includes .._.._.. .  Apparently it is adding a random number as well for
uniqueness.  I guess that this is the downside of building in tree, and
apparently it is rebuilding gettext itself with the different stages of the
compiler, so the appended random number changes.

Thanks, David

Jakub pointed me to -frandom-seed=, which stabilized this, it'd seem.
Running a clean build to test (hacking an existing one worked).

You should be able to work around this by passing the additional option
--disable-libasprintf to gettext-runtime/configure. Nothing in GCC needs
libasprintf; therefore there is no need to build it.

And while at it, I would also pass --disable-java and --disable-csharp.

Ah, sure, that works for me too (note that the fix is to pass
-frandom-seed=, according to Jakub, should this show up again).

Yes, I noticed those and disabled them already.

Indeed, that got a bootstrap to pass.  I've also taken the opportunity
to check the problems Eric Gallager reported.  The install tree seems
clean now, and the info et al targets appear to work again.  David,
Eric, could you check whether the attached patch works for you in the
scenarios you ran into problems with?  Make sure to fetch gettext-0.22.4
into your trees.

Subject: [PATCH] gettext: disable install, docs targets, libasprintf, threads

This fixes issues reported by David Edelsohn <dje.gcc@gmail.com>, and by
Eric Gallager <egallager@gcc.gnu.org>.

ChangeLog:

	* Makefile.def (gettext): Disable (via missing)
	{install-,}{pdf,html,info,dvi} and TAGS targets.  Set no_install
	to true.  Add --disable-threads --disable-libasprintf.
	* Makefile.in: Regenerate.

the patch for review.

Thanks, have a lovely day.

OK, I can confirm that with this patch, my GitHub Actions CI workflow
that had previously been failing is now passing again; you can see the
results here:
https://github.com/cooljeanius/gcc/actions/runs/6948834515/job/18905670645
...and here's a link to a zip of the logfiles generated from the build:
