Mingw-w64 brings free software toolchains to Windows. It hosts a vibrant community which builds and debugs software for Windows while providing development environment for everyone to use.
It has forked mingw.org in order to move forward and provide 64bit support and support for new APIs and has brought countless improvements since its creation in 2007.
Website is evolving. The website is changing; please forgive us for a small lack of polishing for a few days and please report issues you encounter.
More than a million lines of headers are already there and the count is continuously increasing to stay up-to-date with new versions of Windows.
Mingw-w64 is not a compiler project but a project used with compilers. Of course, for simplicity, many pre-packaged toolchains are available in the Downloads section and several of them come with additional libraries and tools for extra convenience.
All the additional libraries needed to link your code and run it directly on Windows are provided along with libraries like winpthreads which provides support for C++11 threading and winstorecompat, a work-in-progress convenience library to ease conformance with the Windows Store.
In addition to the usual compilers, linkers and debuggers from the toolchain, mingw-w64 provides gendef to generate Visual Studio .def files from a .dll, genidl to generate .idl files from a .dll and widl to compile them.
Version 2.0 focused on expanding Windows Vista/7 API support.
