[mpich-discuss] Fedora 12 compiling issues

[rcx11 at yahoo.com]

I would have been using that, but Fedora 12 builds MPICH with gfortran, which is symlinked to f90, and gcc. I don't have symlinks or alias for mpif90 or mpicc. Also, using the mpif90 and mpicc, the installation instructions specify the usage of the -lmpich tag.
