Hi Danyang, Just to reiterate, the presence of -Wl,-flat_namespace *is* the problem. I got rid of it by configuring mpich with --enable-two-level-namespace. I reported this problem to the PETSc folks a few weeks ago and they were going to patch MPICH.py (under config/BuildSystem/config/packages) to pass this flag. So you could try configuring with —download-mpich (or build your own mpich, which is pretty straightforward). If you’re wedded to openmpi, you could patch up OpenMPI.py yourself (maybe --enable-two-level-namespace is called something else for openmpi).
