Re: Interested in participating in Fortran study to compile very large modules

[Arjen Markus <arjen.markus895@gmail.com>]

There are various solutions to install gfortran (or in general the GCC
compiler suite) on Windows: Cygwin and MinGW-w64/MSYS2 are both
environments that mimick to a certain extent Linux and allow you to manage
all manner of packages, among which the GCC compiler suite. I use both but
I also use the installation from equation.com -
http://www.equation.com/servlet/equation.cmd?fa=fortran. You can get Intel
Fortran oneAPI from Intel -

General questions about Fortran: the comp.lang.fortran newsgroup or, a bit
more modern, Fortran discourse - https://fortran-lang.discourse.group/
