why use gcc over mpicc? [mpicc should be internally using gcc so it should satisfy the gcc requiremetn] > I was wondering if someone could point to how i can do that. (Is there an > option that i overlooked?) Look at 'mpicc -show' to determine the include & library options required to use this MPI - and then configure PETSc with: --with-cc=gcc --with-fc=g77 --with-mpi-include=/foo/bar/mpi/include --with-mpi-lib=[/foo/bar/mpi/lib/libmpi.a,anotherlib.a,anotherlib.a] 'mpicc -show' should give the path to libmpi.a and its dependendent libs.
