Oh, you can, but it can be tricky to get the libraries in the right
order.
For example, I'm using the mpi compiler wrappers that came with MPICH
and a separate build of MPE:
$ mpicc h5test.c -o h5test -L${HDF5}/lib -lhdf5 -lm
-L/soft/apps/mpe/install_ibm/lib -llmpe -lmpe
you can also sometimes use your mpi wrapper scripts to do some of this
for you, if you built MPICH2 with MPE support:
$ mpicc -mpe=mpilog h5test.c -o h5test -L${HDF5}/lib -lhdf5 -lm
