Created attachment 388864 [details] build.log Hello ppl, I try to emerge gcc-gnat (needed by sci-electronics/ghdl) but it fails.

checking for C compiler default output file name... configure: error: in `/var/tmp/portage/dev-lang/gnat-gcc-4.6.4/work/build': configure: error: C compiler cannot create executables See `config.log' for more details. Please attach that config.log.
Created attachment 388870 [details] config.log Here you are, hope it helps. Thank you for your time. :)

Jeroen, in the config.log, i see this: conftest.c:1: error: bad value (corei7-avx) for -mtune= switch Maybe this is the issue? If it is, why is corei7-avx a bad value? I configure my flags using the gentoo wiki --> http://wiki.gentoo.org/wiki/Safe_CFLAGS#Core_i3.2Fi5.2Fi7_.26_Xeon_E3.2FE5.2FE7
Because the gcc version used to build gnat-gcc is a a little old and does not "know" about existence of modern processors. Drop any -march/mtune from ???FLAGS and it should work.

But, if i drop the march from my CFLAGS, won't there be a problem with portage? After all, that's why we have CFLAGS on gentoo... Isn't there any other workaround to emerge gnat-gcc?

After all, that's why we have CFLAGS on gentoo... Isn't there any > other workaround to emerge gnat-gcc? Anyway, I removed my march from CFLAGS only to emerge gnat-gcc and it worked... I hope in the future this will be resolved.
I meant temporarily, of course. IMO it will be solved only if a) ada will be accepted as main Gentoo supported language or b) gnat-gcc will be following trunk gcc more closely. I prefer variant a). Needed toolchain.eclass changes are very small for enabling Ada system wide, you only need working gnat-gcc once or Ada language included in Gentoo installation snapshots.

Thank you for the help, i hope in the future gnat-gcc won't have problems as such. :)
