So, if /usr/lib/x86_64-linux-gnu/ is not in the ldflags, then how will the linker find it? Also, I think your patch will select the wrong library if someone's system has /usr/lib/libLLVM-3.3.so and they are trying to use a local installation with the multiple shared objects produced by CMake. Both your solution and the existing solution really just work around what I consider to be a bug in the LLVM project, and I think the best way to fix this would be to submit a patch to LLVM that either: 1. Adds a flag like --has-one-so to llvm-config or 2. Fixes the build systems so that configure and CMake both produce the same shared objects. -Tom _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
