That would be one way it dies, but we kept getting errors during
compilation without the compilation process exiting which is arguably
worse than the behavior you saw.
OpenMPI's mpicc doesn't support the -cc flag so it just passes it to
pgcc, which doesn't support it either. The easy way to fix it is
recompiling OpenMPI with gcc and pgf
./configure CC=gcc CXX=g++ F77=pgf... FC=pgf... ...
After that, edit the WRF configure.wrf and remove every instance of
-cc=${SOMEVAR} I think there should be two, but I don't have access to
mine at the moment to tell you the exact names.

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

WRF almost requires that you use gcc for the C/C++ part and the PGI
Fortran compilers, if you choose that option. I'd suggest compiling
OpenMPI in the same way as that has resolved our various issues. Have
you tried that with the same result?

Howdy,
I'm new to this list. I've done a little review but likely missed
something specific to what I'm asking. I'll keep looking but need
to resolve this soon.
I'm running a Rocks cluster (centos 5), with PGI 7.2-3 compilers,
Myricom MX2 hardware and drivers, and OpenMPI1.3
I installed the Myricom roll which has OpenMPI compiled with gcc. I
recently compiled the openmpi code w/ PGI.
I've the MPICH_F90 pointing to the right place, and we're looking
for the right includes and libs by means of LD_LIBRARY_PATH, etc.
When I tried to run, I got the following error:
make[3]: Entering directory `/home/gerry/WRFv3/WRFV3/external/RSL_LITE'
mpicc -DFSEEKO64_OK -w -O3 -DDM_PARALLEL -c c_code.c

Note that I had modified the makefile to use PGI in place of gcc,
and thus, the PGI-compiled openMPI.
Thanks, Gerry
