This sounds like a LLVM bug to me. If MIPS and ARMS libraries weren't built and installed then 'llvm-config --libs' shouldn't list them. Anyway, Mesa doesn't need LLVM libraries except in `$LLVM_CONFIG --libs engine` to build/run? (In reply to comment #2) > Anyway, Mesa doesn't need LLVM libraries except in `$LLVM_CONFIG --libs engine` > to build/run? I tried the SCons build using 'llvm-config --libs engine' and Mesa fails to build. $ scons [...] Linking build/linux-x86_64-debug/gallium/drivers/llvmpipe/lp_test_blend ... build/linux-x86_64-debug/gallium/drivers/llvmpipe/lp_test_blend.o: In function `test_one': mesa/src/gallium/drivers/llvmpipe/lp_test_blend.c:691: undefined reference to `LLVMWriteBitcodeToFile' build/linux-x86_64-debug/gallium/auxiliary/libgallium.a(lp_bld_debug.os): In function `llvm::InitializeAllDisassemblers()': /usr/lib/llvm-2.8/include/llvm/Config/Disassemblers.def:27: undefined reference to `LLVMInitializeARMDisassembler' Created attachment 56313 [details] [review] Use LLVM_LIBS="`$LLVM_CONFIG --libs engine bitwriter`" Filled bug against LLVM http://llvm.org/bugs/show_bug.cgi?id=11886 Looks like LLVM guys recommend to use more fine-grained llvm-config options with specific LLVM_LINK_COMPONENTS, so Mesa should also use it, if possible (not sure though, waiting for the answer in LLVM bugzilla). llvmpipe also uses bitwriter functions, so use LLVM_LIBS="`$LLVM_CONFIG --libs engine bitwriter`" (now also with scons changes. Can't check scons build, because it's broken for me due to unrelated reasons). Commited.

Created attachment 55273 [details] Use LLVM_LIBS="`$LLVM_CONFIG --libs engine`" As llvm-config says: Typical components: all All LLVM libraries (default). engine Either a native JIT or a bitcode interpreter. `all` contains MIPS/ARM/etc libs, which [AFAIU] is not actually used and is not necessary installed, which leads to build/linking error due to missing libraries.
