Re: trouble installing pyngl in home directory of hopper

Hi Mary,

Thanks. got it to work. there was no libgfortran.so for the default pgi compiler, so I just switched everything to use the gcc compilers using the "module load gcc" command. I then set the env variables as:

export F2CLIBS=gfortran
export F2CLIBS_PREFIX=/opt/gcc/4.6.1/snos/lib/
export FC=gcc
export F90=gfortran
export CXX=gcc
export NCARG_ROOT=/usr/common/usg/ncar/6.0.0

Yours,
Charlie
