Thanks so much.. I only had to use --disable-mpi-f77 and --disable-mpi-f90 in addition to the --host=powerpc-unknown-linux-gnu to have configure work successfully. Ie.
/home/MPI/openmpi-1.2.6/configure --prefix=/home/MPI/openmpi-1.2.6-install-7 448 --host=powerpc-unknown-linux-gnu --disable-mpi-f77 --disable-mpi-f90 -----Original Message----- From: users-boun...@open-mpi.org [mailto:users-boun...@open-mpi.org] On Behalf Of Brian W.

Note that processor family gets lumped together in pretty large chunks. I'm guessing that if you could run config.guess on your machine (it requires a working compiler in some instances), you'd find it would return something like: powerpc-unknown-linux-gnu. If you pass that as --host, I'm pretty sure you'll get what you need. If your cross-compilers are named ppc74xx-linux-gcc, you'll have to then set CC, CXX, FC, and F77 explicitly.
