Description Emil Velikov 2016-10-28 14:40:40 UTC

Since we don't propagate the LLVM_LIBDIR (-L/foo) to the linker we can fail at link stage. That's due to the library variable LLVM_LIBS (as provided by llvm-config --libs) containing only -lfoo.

One workaround is to use, LD_LIBRARY_PATH or alike. Although one should _not_ need to do that in the first place - that's why we have .pc (and equivalents).

The following seems fixes things on my end

Comment 1 Emil Velikov 2016-11-17 15:36:54 UTC

Most likely a issue on my end (or buggy LLVM build) since we propagate LLVM_LDFLAGS throughout mesa. That in itself contains the -L/path/to/llvm/libraries.

We might want to double-check (for missing LLVM_LDFLAGS) at some point in the future. Closing for now.
