In our default build environment for package building GCC no longer builds because of this: [ 152s] /usr/lib64/gcc/x86_64-suse-linux/4.8/../../../../x86_64-suse-linux/bin/ ld: skipping incompatible /usr/lib64/gcc/x86_64-suse-linux/4.8/libgcc.a when sea rching for -lgcc [ 152s] /usr/lib64/gcc/x86_64-suse-linux/4.8/../../../../x86_64-suse-linux/bin/ ld: cannot find -lgcc [ 152s] /usr/lib64/gcc/x86_64-suse-linux/4.8/../../../../x86_64-suse-linux/bin/ld: skipping incompatible /usr/lib64/gcc/x86_64-suse-linux/4.8/libgcc_s.so when searching for -lgcc_s [ 152s] /usr/lib64/gcc/x86_64-suse-linux/4.8/../../../../x86_64-suse-linux/bin/ld: cannot find -lgcc_s [ 152s] collect2: error: ld returned 1 exit status [ 152s] configure: error: I suspect your system does not have 32-bit developement libraries (libc and headers). If you have them, rerun configure with --enable-multilib. If you do not have them, and want to build a 64-bit-only compiler, rerun configure with --disable-multilib. the issue is that while we do have 32bit glibc support installed but not all required files for the host compiler to produce 32bit executables - which isn't needed - the compiler we bootstrap will have all the support for this. In fact, a x86_64 multilib GCC can be just bootstrapped fine with a non-multilib x86_64 compiler which you also disallow with the above check. I don't see how you can do this configure check in its current form early, before you've built the stage1 compiler. So - please consider reverting this patch or at least provide a way to override the check. Thanks, Richard. > FX
