Hi Yuanfu,

Did you install gcc/gfortran from the HPC SourceForge website that is linked in the NCL installation documentation <http://ncl.ucar.edu/Download/macosx.shtml#InstallCompilers>? There is a known version incompatibility regarding those gcc/gfortran packages — NCL requires gcc/gfortran 6.3 <https://sourceforge.net/projects/hpc/files/hpc/gcc/gcc-6.3-bin.tar.gz/download>, but their website makes that particular version hard to find. (Unfortunately, gcc/gfortran version 7.1 linked from their homepage <http://hpc.sourceforge.net/> will not work with the currently available NCL binaries on our website.)

Could you please run the following commands?
which gcc
gcc --version
ls -l /usr/local/lib/libgomp*
