of the config.log conftest.c:1: error: bad value (corei7-avx) for -march= switch changeing -march to `native' "fixes" this. NOTE:this version is no longer supported upstream
configure:3197: /var/tmp/portage/dev-lang/gnat-gcc-4.3.5/work/usr/bin/gnatgcc -march=corei7-avx -O2 -pipe -ggdb -L/var/tmp/portage/dev-lang/gnat-gcc-4.3.5/work/usr/lib conftest.c >&5 conftest.c:1: error: bad value (corei7-avx) for -march= switch This reveals that the -march=corei7-avx switch isn't understood; from a quick guess, I think gcc 4.3.5 might be too old and thus I suggest you set CFLAGS="-O2 -pipe -march=native", upgrade the compiler and then set it back as you see fit.
Going on your hunch I attempted to emerge dev-lang/gnat-gcc: 3.4.6 4.1.2 4.2.3 4.3.5 4.3.6 4.4.3 4.4.5 4.4.7 4.5.4 4.6.4 (all of the avalible versions in the main tree) with the -march=corei7-avx flag. and receved the same error on all versions. I resolved to build with the native flag and leave it alone. As a side note:this ebuild seems to be downloading a precompiled gnat-gcc compiler. Why would it use that when I have a previous version installed? Another thought:Is it our duty to clean the input to this compiler or is it their duty to accept all valiad -march flags?
