[ncl-install] /usr/local/lib/libgfortran.3.dylib

[Kevin Hallock]

Yuanfu,

I’m sorry, I should have also asked you to run the command “/usr/local/bin/gfortran --version”. I suspect that you might have gcc/gfortran version 7.1.0 installed, while the Mac binary release of NCL was built with gcc/gfortran 6.3.0. This is important because gcc <=6.x provides libgfortran.3.dylib, while gcc >=7 provides libgfortran.4.dylib.

If your version of gcc/gfortran is 7.1.0, then downloading and installing the gcc 6.3 tarball from this link should fix the libgfortran issue: https://sourceforge.net/projects/hpc/files/hpc/gcc/ <https://sourceforge.net/projects/hpc/files/hpc/gcc/>

If that does not solve the problem, please let us know so we can continue diagnosing the issue.

I hope this helps!

Kevin
