Same problem here, using LLVM-6.0 from a week ago, my cmake is just -DCMAKE_INSTALL_PREFIX=/opt/xorg -DLLVM_TARGETS_TO_BUILD='AMDGPU;X86' -DCMAKE_BUILD_TYPE=Release -DLLVM_BUILD_LLVM_DYLIB=TRUE llvm-config --libs seems to return tons of output like -lLLVMBitWriter -lLLVMAnalysis -lLLVMProfileData -lLLVMObject ... which seems to result in static linking that's supposedly not supported by mesa? The only .so I see is libLLVM.so , all others are .a files. Meanwhile llvm-config --shared-mode returns "static", which implies it wants be statically linked. There is BUILD_SHARED_LIBS cmake option, but llvm documentation advices against using it and suggests LLVM_BUILD_LLVM_DYLIB instead. Confusing... Also, llvm-config --version says "6.0.0git-f49c401", which means I had to manually hack configure.ac every time to "6.0.0svn" to get mesa building too :( Gražvydas _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
