Elvedin,

Yeah, I thought about that after finding a reference to this in the
archives, so I redirected the path to MPI toward the gnu-compiled
version. It died in THIS manner:
make[3]: Entering directory `/home/gerry/WRFv3/WRFV3/external/RSL_LITE'
mpicc -cc=gcc -DFSEEKO64_OK -w -O3 -DDM_PARALLEL -c c_code.c
pgcc-Error-Unknown switch: -cc=gcc
make[3]: [c_code.o] Error 1 (ignored)

Methinks the wrf configuration script and make file will need some tweeks.

Interesting thing: I have another system (alas, with mpich) where it
compiles just fine. I'm trying to sort this out, as on 2 systems, with
openMPI, it does odd dances before dying.

I'm still trying things. I've gotta get this up both for MY research
and to support other users.

Thanks, Gerry
