Hi,
i just built GCC 4.0.0 on AIX 5.1 using the following commands:
../gcc-4.0.0/configure --with-libiconv-prefix=/usr --disable-nls --disable-multilib
make bootstrap-lean
make install
$ config.guess powerpc-ibm-aix5.1.0.0
$ gcc -v
Using built-in specs.
Target: powerpc-ibm-aix5.1.0.0
Configured with: /home/linke/temp/gcc-4.0.0/configure --with-libiconv-prefix=/usr --disable-nls --disable-multilib
Thread model: aix
gcc version 4.0.0
The system is an IBM pSeries M80 with AIX 5.1 at the latest patchlevel. The building c-complier is gcc 3.4.3 Make is gnu-make 3.80
The disable-xxx configure-options shouldn't be necessary, i used them for buildtime- and space-saving reasons.
The whole build took less than two hours.
