[llvm-dev] Link error on Linux

I'm trying to link a program with LLVM on Linux. I've managed to take out
the test files from 'llvm-config --libs' but now it's getting errors with
missing symbols. The same program successfully links with the same version
of LLVM (3.8) on Windows, so it's not a problem with the code per se, it's
some kind of configuration issue. Any ideas?
