Error with install_wps_openmpi.sh - geogrid.exe and metgrid.exe not built. about azurehpc HOT 6 CLOSED

Turns out that the fix above was not sufficient. I ended up having to override the MPI_LIB fix in the install_wps_openmpi.sh script itself. See changes in my branch:

Is the openmpi module being loaded correctly?

[cyclecloud@ip-0A060006 ~]$ module load mpi/openmpi-4.0.3
[cyclecloud@ip-0A060006 ~]$ set | grep MPI
MPI_BIN=/opt/openmpi-4.0.3/bin
MPI_HOME=/opt/openmpi-4.0.3
MPI_INCLUDE=/opt/openmpi-4.0.3/include
MPI_LIB=/opt/openmpi-4.0.3/lib
MPI_MAN=/opt/openmpi-4.0.3/share/man

So it is module load mpi/openmpi-4.0.3 that is setting the MPI_LIB env var.

However I am not sure if it is being set to an incorrect value OR if it is the WPS configure setup that is using it incorrectly. In any case it end up not building all of the required WPS executables.

Thanks

Thanks for finding this build error. I took a closer look at it today. Here is the problem.
The OpenMPI modulefile set MPI_LIB to the location of its libraries. WPS used MPI_LIB
directly in its Makefiles (without a -L option) and so we see the Makefile build error. Since WPS
uses the mpi wrappers (mpif90, mpicc) it does not need MPI_LIB, because the wrappers already know the location of the openmpi libraries and include files. So, one simple solution is to just unset MPI_LIB (ie export MPI_LIB=""). I have create a PR (#295 ) with this fix.
