mingw-w64

GCC for Windows 64 & 32 bits

Mingw-w64

Mingw-w64 is an advancement of the original mingw.org project, created to support the GCC compiler on Windows systems. It has forked it in 2007 in order to provide support for 64 bits and new APIs. It has since then gained widespread use and distribution.

The development and community are very active and welcoming with new contributors every month and simple installers.

Version 7 has been released

v7.0.0: 2019-11-10

Notable changes:

  • _FORTIFY_SOURCE support thanks to Christian Franke.
  • Lots of math fixes from Martin Storsjö.
  • Many headers updated from Wine by Jacek Caban.
  • UCRT support by Martin Storsjö.
And many other additions thanks to, but not limited to (in Alphabetical order)
