NOTE: Newer versions of Matlab now natively support Mingw, negating the need for this package. MSYS2 is a much smaller package (in terms of disk pace needed), and is used by several other free projects: R (Rtools), Octave and Strawberry Perl all include parts of it, including the gcc compilers. 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 or g95. ![]() The speed of the gfortran is pretty much on par. Intel oneAPI is at least partly open source, not sure about the Fortran compiler. The intel fortran (as you mentioned in your first post) is the fastest under windows 10 and i7 of all the compilers on average by about 50-100. Available on Linux, macOS and Windows (of course, Visual Studio is needed only on Windows). There is also a separate distribution of mingw-w64 that can be installed without MSYS2, but I don't recommend it, as the last files there have gcc-8.1.0, from 2018 (apart from a recent build by Ray Linn that includes the Ada, but not the Fortran compiler).Īnother compiler that is now free is Intel Fortran : you have to install Microsoft Visual Studio Community, Intel oneAPI Base Toolkit and Intel oneAPI HPC Toolkit. ![]() If you want to use gfortran on Windows, I suggest you install MSYS2, which has a bash terminal, and a package manager that can install gcc and gfortran, as well as lapack and many other libraries.
