If I were you, I certainly wouldn't trust this build if make check doesn't work but LIBMESH_RUN="mpirun -np 2" make check does. What compilers are you using on OSX? There have been numerous threads where people have had trouble using the very old GCC that comes with Lion and Mountain Lion. If you're using the system GCC, I'd strongly recommend building or (downloading via macports) a newer compiler and compiling your whole stack (starting with MPI) using it instead. -- John ------------------------------------------------------------------------------ Introducing Performance Central, a new site from SourceForge and AppDynamics.
