Why do you need the same version at runtime than the one it was compiled with? Multiple definitions doesn't sound like a good reason to me, as eigen and ceres shouldn't be defining things in the same namespace in the first place, thus conflicts should be impossible. Sounds like a too strict check that should be removed. Emilio
