The configure/make system.

Yes.

In the meantime, I had a closer look on which particular symbol was missing. It turned out that the llvm::Calculate template (used by DominatorTreeBase::recalculate, which I call in my pass) is declared in llvm/Analysis/Dominators.h, but is implemented in DominatorInternals.h. *) When I include that header directly as a workaround, my pass works fine.

Cheers,
Julian

*) I forgot to mention that I'm still using the release_33 branch; in the trunk, the dominator tree computation code has been restructured, and no longer causes this linker problem in my example.
