When building shared binutils-cross with OpenEmbedded I got this error: ar: can't set BFD default target to `x86_64-pc-linux-gnu': Invalid bfd target First I was trying to enable USE flag multitarget, but that didn't help. So I tried newer binutils snapshosts 2.20.51.0.8 and 2.20.51.0.9, both failed but 2.20.51.0.8 was quite easy to fix (I'll attach used patch), but still BFD targets weren't available. In this 2.20.51.0.9 announcement http://gcc.gnu.org/ml/gcc/2010-05/msg00632.html I noticed "IA-32 binary and X64_64 binary tar balls are configured with --enable-gold=both/ld --enable-plugins --enable-threads.", so I tried to add --enable-plugins --enable-threads to toolchain-binutils.eclass. Now building binutils-cross works OK, but would be great to resolve it properly in all binutils versions. Some more details: http://article.gmane.org/gmane.comp.handhelds.openembedded/33294/match=latest+binutils I'm using masked gcc-4.5, but I had confirmation from other OpenEmbedded user that he has the same issue on his stable x86 gentoo ("ar: can't set BFD default target to `i686-pc-linux-gnu': Invalid bfd target" for him).

Created attachment 234687 [details, diff] toolchain-binutils.eclass.patch enable plugins and threads in for binutils in toolchain-binutils
Created attachment 234689 [details, diff] binutils-2.20.51.0.8.patch Version 2.20.1-r1 had similar patch ./patches/binutils-error-9.patch, which is changing the similar problem on more places, maybe this whole patch is still needed for binutils-2.20.51.0.8.
Hello Martin, can you please provide the full build.log, just for the record. thanks for the patch, Michael

(In reply to comment #3) > Hello Martin, > > can you please provide the full build.log, just for the record. > > thanks for the patch, Michael Attached, but to be clear: I'm building binutils-cross with OpenEmbedded (not from some ebuild), but gentoo binutils is used to link it and building shared binutils-cross was just first place exposing this "bug" in gentoo binutils. Maybe this issue is related to #76436 #203124
most likely you're hitting an upstream bug. not a problem with Gentoo. http://sourceware.org/bugzilla/show_bug.cgi?id=4970
