[ncl-install] problem about installing ncl on macos

[Kevin Hallock]

Hi Zeyuan,

Could you please try running the following command and reply with the output:
ls -l /usr/local/lib/libgfortran*

I think GCC/Gfortran 8.1.0 includes the library file “libgfortran.5.dylib” instead of the “libgfortran.4.dylib” (from GCC/Gfortran 7.3.0) that this particular build of NCL was compiled with, which is causing the “library not loaded” error at run time.

If that is the case, you will likely need to install the gcc-7.3-bin.tar.gz tarball from this site: http://hpc.sourceforge.net/ <http://hpc.sourceforge.net/>

I hope this helps,
Kevin
