Take a look here to what I'm currently using: http://code.google.com/p/petsc4py/source/browse/conf/core/confcore.py#144 I'm not saying that this is optimal, I've always used what PETSc provides. > ?

That variable expanded to "-lpetsc" for single-lib builds, and "-lpetscts -lpetscsnes ..." for the multi-lib case. > ?
