I believe the problem is that it's trying to use the system-default gcc here
checking for mpiexec... /home/cponder/WRF/PGI/105.OpenMPI/bin/mpiexec
checking for gcc... /bin/gcc
checking C compiler for serial utility programs... /bin/gcc
which is incompatible with all the NVHPC_specific paths that I'm setting for the overall build:
export CC=`which pgcc`
export CXX=`which pgc++`
export F77=`which pgf77`
export F90=`which pgf90`
export FC=`which pgfortran`

export MPICC=`which mpicc`
export MPICXX=`which mpicxx`
export MPIF77=`which mpif77`
export MPIF90=`which mpif90`

export   CFLAGS="-fPIC -m64 -tp=px"
export CXXFLAGS="-fPIC -m64 -tp=px"
export  FCFLAGS="-fPIC -m64 -tp=px"

export LDFLAGS+=" -L$PGI/cuda/lib64 -lnvidia-ml"
I'm guessing that the old compilers & old OS levels didn't enable these types so there was no collision during the compilation.
Is there a way to override the gcc default for the utilities? I don't see any such setting in the configure --help output.
