Bug 421255 – sys-devel/gcc-4.7.x build fixes

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description safety0ff.bugz 2012-06-15 16:05:25 UTC]

Gcc 4.7.0 does not build with CFLAGS/CXXFLAGS = -march=native -mno-avx due to upstream bug #53113.

Gcc 4.7.1 does not build with USE "go" due to upstream bug #53679, and suffers from the above issue too.

I've submitted my patches upstream, I've put working ebuilds here: https://github.com/Safety0ff/ebuilds/tree/master/sys-devel/gcc
Patches are in the files/${PV}/ directories.

Reproducible: Always

I confirm that patch gcc-4.7.1-libgo-runtime.diff at the URL above solves the build problem when USE "go" is enabled.

That bug says it fails because of -Werror, which we don't allow.  If -Werror is being passed then we should fix that, otherwise it doesn't affect us.

PS.  Please file individual bugs in the future, with build logs and emerge --info.  Patches need to be attached, not put in a repo somewhere.
