Linux

Install a fortran compiler with the package manager, like gfortran.

macOS

- Install Miniconda - See https://conda.io/miniconda.html

 ./Miniconda3-latest-MacOSX-x86_64.sh -p /Volumes/D/Support/miniconda3/
 Do you wish the installer to prepend the Miniconda3 install location
 Answered NO

- To activate of base env.

 source /Volumes/D/Support/miniconda3/bin/activate

- Add conda-forge

 conda config --add channels conda-forge

-Then create gfortran-env and install gfortran

 conda create -n gfortran-env
 conda activate gfortran-env
 conda install gfortran_osx-64

Before packaging, we have to fix the installed gfortran libraries with the following script: fix_gfortran_lib_rpath.sh.

The script substitutes @rpath with the needed full paths. Requires atool and install_name_tool.

Windows

- Install Miniconda - See https://scikit-ci-addons.readthedocs.io/en/latest/addons.html#install-miniconda3-4-5-4-ps1

- Install Flang, a fortran compiler targeting llvm: scikit-ci-addons
