• Status: RESOLVED FIXED

When I try to build llvm-gcc, it fails because I don't have a stubs-32.h file only stubs-64.h:

Thanks for the report!

So there's some no-multilib handling missing, I'll check in toolchain eclass (as this is basically a gcc build) what is needed in this case

Created attachment 208460 [details, diff]
llvm-gcc-2.6.ebuild patch to handle multilib

Can you try this patch to llvm-gcc-2.6.ebuild? It adds a multilib USE flag, which should disable all 32bit parts generation on no-multilib

Thanks, that fixed it!  Everything compiles fine now.

Great! Thanks for testing, I've committed it in portage CVS
