[mpich-discuss] mpi_lib

[Darius Buntinas]

When compiling an mpi application it's best to use the compiler wrappers (i.e., mpicc, mpic++, mpif90 and mpif77) rather than specifying the includes and libs yourself.  I suspect that the mpicc on the MCS machines is old (before we used mpl) so if you're linking with that library you don't need -lmpl.  Alternatively you can install your own MPICH library as Pavan suggested.

But in either case, you should use the compiler wrappers provided.
