[petsc-users] Can not find the header file for OpenMPI

[Satish Balay]

If you are using mpicc/mpif90 as compilers from you pre-installed MPI - you don't need to list --with-mpi-include, --with-mpi-lib options.

As mentioned - you can do this either with:

[if you have then in PATH] --with-cc=mpicc --with-cxx=mpicxx --with-fc=mpif90

or:

--with-cc=MPI-DIR/bin/mpicc --with-cxx=MPI-DIR/bin/mpicxx --with-fc=MPI-DIR/bin/mpif90

or

--with-mpi-dir=MPI-DIR

If you are having trouble with any of the above modes - resend configure.log for it.
