It looks to me like what's happening is -ludis86 is appearing before -lLLVMSupport on the command line and since both are static libraries, it's getting undefined references.
Unable to reproduce with =dev-libs/udis86-1.7, =sys-devel/llvm-2.9-r2, and either mesa-7.11 or mesa-9999.
(In reply to comment #1) > It looks to me like what's happening is -ludis86 is appearing before > -lLLVMSupport on the command line and since both are static libraries, it's > getting undefined references. You're right. I unpack and confgure mesa with the ebuild command and I compile the llvmpipe driver within its directory with the same problem as describe above. If I take the command line and move -ludis86 at the end of the LLVM libs it works. How can I fix it ?

I think the problem is something local on your system. Try reinstalling udis86 and llvm?

Same problem with your command line. It's very strange. Can you give me your --info and your ld version ?

Created attachment 286813 [details, diff] By moving LDFLAGS in group with LIBS, the link doesn't make problem anymore.
I got a patch but I don't know why by it works every where except for me by default. Install a newer binutils doesn't help. And I don't know why llvmpipe is built with mesa because the driver doesn't appear in configure options (--with-dri-drivers=,swrast,radeon,r200,r300,r600 --with-gallium-drivers=,swrast,r300,r600). Is it build always by default ?
Created attachment 286815 [details, diff] A patch to mesa ebuild. Maybe a mesa-7.11-r1.ebuild
(In reply to comment #10) > And I don't know why llvmpipe > is built with mesa because the driver doesn't appear in configure options > (--with-dri-drivers=,swrast,radeon,r200,r300,r600 > --with-gallium-drivers=,swrast,r300,r600). Is it build always by default ? softpipe (gallium3d software rasterizer, or swrast) uses LLVM with USE=llvm and then is called llvmpipe.
I'm going to close as WORKSFORME, since I don't know what else I can do. I really think it's something weird about your setup.
