Hi,
You haven't told the loader (via f77) which libraries contain the LAM MPI
routines nor where the LAM MPI libraries are.
Use "mpif77" instead. This invokes the loader with the LAM MPI libraries.
Make sure you have the location of the LAM binaries in your PATH, e.g.
PATH=/usr/local/lam/bin:$PATH ; export $PATH
mpif77 -qnoextname -qmaxmem=-1 -o test test.F
See the User's Guide on the LAM-MPI website.
Regards
Neil
