I'm not sure why ld thinks LLVM is involved, vtk does not pull in LLVM
in any way.
I'm pretty much clueless, any ideas?
That looks like the object file requires a symbol from libLLVM, and gcc
isn't linking against it (hence the "DSO missing from command line" part).
If you have a log of the whole build you should be able to check how
that object (the test) is being built; LLVM suggests maybe it was built
using clang?
Compiling using clang wouldn't cause an object to link against
libLLVM.so. However, as Will said, we really need the whole log to
understand better what is happening.
