Cross-compilers

On Debian/Ubuntu-like systems, cross-compilers can be installed with the following command:

$ sudo apt-get install gcc-mingw-w64 g++-mingw-w64 gfortran-mingw-w64

On macOS, using Brew, the cross-compilers can be installed as follows:

$ brew install mingw-w64

Other package managers offer corresponding packages.

An alternative to using packaged cross-compilers is to build them from sources, using the M cross environment (https://mxe.cc).
