Gnumex is a package that allows Matlab mex and engine files written in C, C++, Fortran 77 or Fortran 95 to be compiled with MinGW (or Cygwin) MS Windows versions of gcc, gfortran, g77 or g95. Here are some of the features in gnumex:

• Compile Matlab mex files using gcc on Windows
• Compatible with 64 bit MATLAB using Mingw-w64 and 32 bit MATLAB using mingw-w32 or mingw
• Allows gcc to appear in the list of compilers shown by mex -setup, and easy switching
• C, C++, Fortran 77 or Fortran 95 mex files

Gnumex is currently thoroughly outdated. However, Matlab has been offering support for the MinGW C compiler since version R2015b, and it is possible to call Fortran from C. There is some discussion and an example in a new post on the Gnumex discussion page.

With new changes to Matlab (and possibly also MinGW-w64) gnumex is yet again out of date it seems. However, I came across a solution on stackoverflow (scroll to 1st answer, with heading mingw_mexopts.bat) that allowed me to mex with MinGW-w64. The solution bypasses gnumex by providing an options file that seems to work. I have just posted my version of the file to the gnumex mailing list. Kristjan.
