I think that I'm already doing this (with pgi 5.2-4, not 6 yet..) and gcc.
I thought that it was all about setting the environment variables before
./configure 'ing lam-mpi:
export FC=pgf90
export FFLAGS=" -fastsse -tp k8-64 -Minfo -V -g77libs "
export CC=gcc
export CFLAGS="-O3"
export CPPFLAGS="-O3"
export CXX=g++
export CXXFLAGS="-O3"
export F77=pgf77
This seems to work fine for separate fortran and c++ mpi code, but perhaps my
setup is horribly broken and I'll have to break down and buy pgcc after all...
