When I Emerge gnat-gpl it errors in configuration with the following error: checking for gcc... /var/tmp/portage/dev-lang/gnat-gpl-4.1.3.2007/work/usr/bin/gnatgcc checking whether the C compiler (/var/tmp/portage/dev-lang/gnat-gpl-4.1.3.2007/work/usr/bin/gnatgcc -O2 -mtune=athlon-xp -pipe -L/var/tmp/portage/dev-lang/gnat-gpl-4.1.3.2007/work/usr/lib/gnatgcc/i486-pc-linux-gnu/4.1) works... no configure: error: installation or configuration problem: C compiler cannot create executables. * * ERROR: dev-lang/gnat-gpl-4.1.3.2007 failed. * Call stack: * ebuild.sh, line 1647: Called dyn_compile * ebuild.sh, line 988: Called qa_call 'src_compile' * ebuild.sh, line 44: Called src_compile * ebuild.sh, line 1327: Called gnatbuild_src_compile * gnatbuild.eclass, line 371: Called gnatbuild_src_compile 'all' * gnatbuild.eclass, line 377: Called gnatbuild_src_compile 'configure' 'make-tools' 'bootstrap' 'gnatlib_and_tools' 'gnatlib-shared' * gnatbuild.eclass, line 454: Called die * * configure failed * If you need support, post the topmost build error, and the call stack if relevant. * A complete build log is located at '/var/tmp/portage/dev-lang/gnat-gpl-4.1.3.2007/temp/build.log'. * Reproducible: Always Steps to Reproduce: Both: gcc 4.1.2 and 4.2.0 are installed.

Hi Nicholas. Sorry for the delay, I was away forsometime. I cannot reproduce this: checking whether the C compiler (/var/tmp/portage/dev-lang/gnat-gpl-4.1.3.2007/work/usr/bin/gnatgcc -march=athlon64 -O2 -pipe -fomit-frame-pointer -L/var/tmp/portage/dev-lang/gnat-gpl-4.1.3.2007/work/usr/lib/gnatgcc/x86_64-pc-linux-gnu/4.1) works... yes I suspected this might be related to gcc-4.2 that you have active, so I switched to it, but it all seems fine. AsI see, you have in your emerge --info: CBUILD="i486-pc-linux-gnu" CFLAGS="-O2 -mtune=athlon-xp -pipe" CHOST="i486-pc-linux-gnu" 1. Why CHOST != i686-pc-linux-gnu? Did you edit this in make.conf yourself? (normally you shouldn't change this) 2. Why wouldn't you use -march=athlon-xp instead of-mtune? What is the actual architecture? Also 3. Do you, by chance, have multiple SLOTs of gcc installed andswitch back and forth often? If so, did you use eselect compiler or gcc-config? IIRC there were problems with eselect compiler module. This error usually happens when you have your toolchain misconfigured. I guess you recently rebuilt your system with gcc-4.2, chances are something is missing. I am afraid I can only suggest running emerge -e world if above questions do not point to something apparent.. George
(In reply to comment #3) I've also had this issue, on other ebuilds (most recently on sys-libs/db-4.3.29-r2) I did some digging and found that the ./configure script had called GCC with invalid options, in my case passing --default-symver to ld I think last time it happened I figured out a work-around, but I can't remember what, and I think that was on a machine that had other problems whereas today's incident was on a believed-to-be-clean machine. BTW, I'm using GCC-4.1.2 on a P3 with CHOST=i686-pc-linux-gnu and CFLAGS="-O2 -march=pentium3 -fomit-frame-pointer"
I've now fixed my instance of a problem very like this. It was caused by (one of) two configuration issues: - For historical reasons, I had blocked the latest glibc in /etc/portage/package.mask and forgotten to remove that block - The system was using an old version of binutils Fixing the first (and updating glibc) didn't help, in fact it made the problem universal. But running binutils-config to fix the second seems to have cured the issue. Nicholas, I suggest you verify that you are actually *using* binutils-2.17, not just that it's installed!
Thanks Robert! Yes, in my experience all reports like this were caused by local misconfiguration. Majority (or may be even all) were specifically due to problems with binutils.. George
no additional reports in quite some time. Seems to work otherwise. Closing the bug.
