Hi,
Thanks for your help.
I changed to mpif77 but the result is the same. However, if I change
MPI_INIT_ to MPI_Init, the first line of error is gone:
> ld: 0711-317 ERROR: Undefined symbol: .mpi_init
<---
> ld: 0711-317 ERROR: Undefined symbol: .mpi_comm_rank
> ld: 0711-317 ERROR: Undefined symbol: .mpi_comm_size
Shall I change them all, or is there any workaround ?
Thanks again.
Best Regards,
/ST

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
