It's not clear exactly what you did here. Did you just replace
MPICH's "mpiCC" with OMPI's "mpiCC"? FWIW, this is almost always the
easiest way to compile MPI applications: use that implementation's
"wrapper" compiler (I'm assuming you have a C++ code in this case).
These errors should not normally happen; they look kinda like you're
somehow inadvertently mixing Open MPI and MPICH.
