It's possible libmesh is using the wrong mpicc/mpicxx compilers when you use this configuration line. It will use the first one it finds in your path, *not* the one you downloaded with PETSc. So could you try: CXX=/path/to/petsc/mpich/bin/mpicxx CC=/path/to/petsc/mpich/bin/mpicc ./configure and see if you have any better luck with the executables? -- John ------------------------------------------------------------------------------ Simplify data backup and recovery for your virtual environment with vRanger.
