Hi,
trying to build gcc-4.4.0 breaks on AIX-5.3 (4.3.3 build worked fine with same
setup),
the small patch below works around the AIX limitations:
/usr/local/bin/bash ./libtool --tag=CC --mode=link
/scr/os-aix53/koenig/gcc-4.4.0-1/ARENA/32/./gcc/xgcc ...
libtool: link: /scr/os-aix53/koenig/gcc-4.4.0-1/ARENA/32/./gcc/nm -B
-X32_64 -BCpg .libs/backtrace.o .libs/compile_options.o ...
libtool: link: /scr/os-aix53/koenig/gcc-4.4.0-1/ARENA/32/./gcc/xgcc
-B/scr/os-aix53/koenig/gcc-4.4.0-1/ARENA/32/./gcc/ ...
./libtool: line 7838:
/scr/os-aix53/koenig/gcc-4.4.0-1/ARENA/32/./gcc/xgcc: Arg list too long
gmake[3]: *** [libgfortran.la] Error 126
gmake[3]: Leaving directory
`/scr/os-aix53/koenig/gcc-4.4.0-1/ARENA/32/powerpc-ibm-aix5.3.0.0/libgfortran'
the actual command line is ~11 Kbytes.
part of the problem is the large amount of environment variables
which sum up with the arg list on AIX (from within make/build):
env | wc
232 540 15090
here is a list of the environment vars before calling libtool in make
with the lenght of this var first, sorted
...
345 CC_FOR_TARGET=...
355 GFORTRAN_FOR_TARGET=...
917 CXX=...
928 CXX_FOR_TARGET=...
4668 MAKEFLAGS=w -- DESTDIR= RPATH_ENVVAR=LD_LIBRARY_PATH
TARGET_SUBDIR=powerpc-ibm-aix5.3.0.0 bindir=/usr/local/gcc-4.4.0/bin ...
just cleaning up MAKEFLAGS (saving 4.5K) is enough (for now;) to get libtool/gcc
running and exec'ing with that long arg list:
