I have built static i686 compiler with multilib support (i686-linux-gnu-gcc/gcc -m64 works with that one), but now I am trying to build shared set of compilers including c, c++ and ada one (I have built static gnat stuff with static gcc), but I still keep failing with same error as in the bug report, ie - no x86_64 support. Looking at config.log it seems to be using xgcc from stage1 bootstrap which isn't multilib capable for some reason. So, what am I still doing wrong? I want i686 compiler, but I also want it to be able to use -m64 with it.Sorry I missed saying this last time: please reply to gcc-help, not just to me. Thanks. Did you configure with --enable-targets=all ? Ian
Whoops, sorry. I just hit reply and didn't pay attention to e mail address which was sent to.
Yes, I configured static gcc with --enable-targets=all and even dynamic. $ /usr/gcc/bin/gcc -v Using built-in specs.
