[Bug libstdc++/19995] New: libstdc++ fails to build correctly on AIX 5.2

[quanah at stanford dot edu]

I had no problem building gcc-3.3.1 on this system.  However, when I went to
build gcc-3.4.3, it failes in the ppc64 portion of libstdc++.  The error given
is the same as seen in this very old thread:

<http://gcc.gnu.org/ml/gcc/2001-06/msg01217.html>

Configure is run as:

cd ../gcc-build/rs_aix52 && CONFIG_SHELL=/usr/pubsw/bin/bash CFLAGS=-O CC=gcc sh
../../gcc-3.4.3/configure \
    --datadir='${prefix}/lib' --libexecdir='${prefix}/lib' \
    --sharedstatedir='${prefix}/lib' --prefix=/usr/pubsw \
    --with-as=/usr/bin/as \
    --with-ld=/usr/bin/ld \
    --with-ar=/usr/bin/ar \
    --with-included-gettext \
    --with-libintl-prefix=/usr/pubsw \
    --with-libiconv-prefix=/usr/pubsw \
    --enable-languages=c,c++,f77,java,objc

The failure error is:

Cannot run a 64-bit program on a 32-bit machine.

You want --disable-aix64 but that does not work for 3.4.x where x < 4 (maybe even when build 
normal it should have dected it I don't know).

Anyways this is a dup of bug 18033 which is already fixed for 3.4.4.

I disagree that this is a duplicate of 18033.

I applied the following patch to gcc-3.4.3:

--- gcc-3.4.3/config-ml.in.orig 2005-02-15 21:37:41.000000000 -0800

+  \'*\') eval option=$option ;;
+  esac

   case $option in
   --*) ;;
   -*) option=-$option ;;


Then completely reconfigured and started a rebuild of gcc, and I get the same
exact error.

never mind, i forgot to run autoconf to regenerate configure after applying the
patch.

The patch listed in bug 18033 does *not* fix the problem.

After applying the patch, and regenerating the top level configure via autoconf
(just to be safe), I still have the exact same bootstrapping problem listed here.

checking for C compiler default output... a.out
checking whether the C compiler works... configure: error: cannot run C compiled
programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details.

Also note that my case differs from 18033 because I'm *not* setting:

--disable-aix64 (--enable-aix64=no)

My configure options worked fine with gcc-3.3.1.

I'm currently testing using the config-ml.in file from gcc-3.3.1 instead of the
one supplied with gcc-3.4.3 to see if I hit the same issue, as the
gcc/config/rs6000/t-aix2 file hasn't changed since 2003, so it would seem the
error happened at some point inside config-ml.in changes.

using config-ml.in from gcc-3.3.1 also didn't resolve the problem.  I can only
assume the problem lies elsewhere.

Any ideas?

GCC 3.4 requires that it can build and run an application in every multilib
variant for which it tries to build a target library.  This technically is not
necessary, but that is the way it currently works.  You either need to build on
a 64-bit system or disable 64-bit libraries.  If you do neither, GCC 3.4 is
working as designed.

I think we can safely close this one.
