This is an old revision of the document!


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.

Notable changes:

  • New Hyper-V headers and libraries by Biswapriyo Nath
  • Many headers updated from Wine by Jacek Caban.
  • ARM math improvements by Martin Storsjö
  • floating point fixes by Liu Hao
  • many *printf compatibility fixes by Liu Hao and Martin Storsjö
  • massive Windows App Store API updates by Steve Lhomme
  • winstorecompat library updates by Martin Storsjö
  • __USE_MINGW_ANSI_STDIO now automatically enabled in C99 and C11 mode when not using UCRT by Pali Rohár

Headers, Libraries and Runtime

  • More than a million lines of headers are provided, not counting generated ones, and regularly expanded to track new Windows APIs.
  • Everything needed for linking and running your code on Windows.
  • Winpthreads, a pthreads library for C++11 threading support and simple integration with existing project.
  • Winstorecompat, a work-in-progress convenience library that eases conformance with the Windows Store.
  • Better-conforming and faster math support compared to Visual Studio's.

Tools

  • gendef: generate Visual Studio .def files from .dll files.
  • genidl: generate .idl files from .dll files.
  • widl: compile .idl files.
