Hi Esteban,

I’m sorry for the inconvenience.

The version of gcc/gfortran required for the Mac build of NCL is 6.3, which is unfortunately a bit hidden on the HPC SourceForge site that our installation procedures link to. It looks like you have gcc/gfortran version 7.1 that is available directly from their home page.

Here’s a direct link to gcc 6.3: https://sourceforge.net/projects/hpc/files/hpc/gcc/gcc-6.3-bin.tar.gz/download <https://sourceforge.net/projects/hpc/files/hpc/gcc/gcc-6.3-bin.tar.gz/download>
