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?
