Yeah, I'm definitely having headaches with LLVMTransformUtils, which
needs to appear before LLVMAnalysis and lLLVMTarget.
-lLLVMTransformUtils -lLLVMAnalysis -lLLVMTarget
If I don't do this, I get link errors on:
I think, for now, the only portable workaround is for me to link all
the *.a libraries in that loop twice, and hope we can clean up the
There's several places where llvm-config could be simplified quite a
bit if we broke the unnecessary dependencies and merged the remaining
loops into single *.a files. In some sense, parts of llvm-config are
re-inventing the system linker. Depending on your point of view, this
might be a bad thing. :-)
Many thanks to everyone who's helped sort this out!
