Confirmed with GCC 4.8.3. (In reply to Jeroen Roovers from comment #3) > Confirmed with GCC 4.8.3. is this only on i686? also does it work with gcc 4.7? The -fuse-ld option was added in gcc-4.8. It generates an error with gcc-4.7. Also, have a look at sys-boot/grub:2 for a more compatible solution. Snippets below.

Apologies -- next time I try and fix a system package I will do a lot more testing (including more than one toolchain version) before committing. @@ -4,0 +5,4 @@ + 22 Oct 2014; Ian Stakenvicius (_AxS_) <axs@gentoo.org> grub-0.97-r14.ebuild: + grub:0 - Only apply -fuse-ld=bfd when gcc is new enough to support it, bug + 526348 + you shouldn't test gcc versions. this is why we have test-flags-CC. append-ldflags $(test-flags-CC -fuse-ld=bfd) + 22 Oct 2014; Mike Gilbert <floppym@gentoo.org> grub-2.02_beta2-r2.ebuild, + grub-9999-r1.ebuild: + Use test-flags-CC instead of gcc-version check, thanks to vapier. + 22 Oct 2014; Ian Stakenvicius (_AxS_) <axs@gentoo.org> + -files/grub-0.97-force-ld.bfd.patch, grub-0.97-r14.ebuild: + grub:0 - undid the ugly patch-based hacks for forcing ld.bfd, thanks to vapier + and floppym Commit message: Use new toolchain helpers for selecting the bfd linker http://sources.gentoo.org/sys-boot/grub/grub-0.97-r14.ebuild?r1=1.6&r2=1.7 http://sources.gentoo.org/sys-boot/grub/grub-2.00_p5107-r2.ebuild?r1=1.9&r2=1.10 http://sources.gentoo.org/sys-boot/grub/grub-2.02_beta2-r3.ebuild?r1=1.5&r2=1.6 http://sources.gentoo.org/sys-boot/grub/grub-2.02_beta2-r6.ebuild?r1=1.3&r2=1.4 http://sources.gentoo.org/sys-boot/grub/grub-2.02_beta2-r7.ebuild?r1=1.6&r2=1.7 http://sources.gentoo.org/sys-boot/grub/grub-9999-r1.ebuild?r1=1.29&r2=1.30 |
