I am using LAM-7.1 on Centos-3.3.x86_64 with Myrinet and the PGI compilers.
Lam builds fine, but I am having a linking problem with mpicc:
$ mpicc --show mpi-hello.c
/usr/pgi/linux86-64/5.2/bin/pgcc -D_REENTRANT mpi-hello.c -lpthread --rpath /usr/local/lib -L/usr/lib64 -lmpi -llam -lutil -lpthread -lgm -lpthread -ldl
$ mpicc mpi-hello.c
pgcc-Warning-Unknown switch: --rpath
mpi-hello.c:
PGC-W-0095-Type cast required for this conversion (mpi-hello.c: 42)
PGC-W-0095-Type cast required for this conversion (mpi-hello.c: 45)

PGC/x86-64 Linux/x86-64 5.2-4: compilation completed with warnings
File with unknown suffix passed to linker: /usr/local/lib
/usr/local/lib: file not recognized: Is a directory
PGI doesn't seem to deal with --rpath without the -Wl, prefix, but with it it
works:
# /usr/pgi/linux86-64/5.2/bin/pgcc -D_REENTRANT mpi-hello.c -lpthread -Wl,--rpath,/usr/local/lib -L/usr/lib64 -lmpi -llam -lutil -lpthread -lgm
-lpthread -ldl

(notice /usr/local/lib was included :)
I will need mpicc to work on this cluster properly. Are there any work arounds
or patches that I can try?
Thanks!
