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 5 has been released

v5.0.4: 2018-06-04

  • Fix gcc-8.1.0 compatibility regarding _xgetbv
  • %e printf specifier will now produce at least 2 digits for the exponent.

initial v5 Release: 2016-10-19

  • Fixes to the __mingw_printf family of functions.
  • DirectX updates from Wine.
  • Various updates to support Windows 7 and 10.
  • Various header typo fixes.

You can also look at the full list of versions.

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.

I was using version 8.1.0, and was unaware version 9 aven existed. I installed Mingw as a standalone. I'll try installing with msys2. Thanks a lot.

This is fixed in version 9.x. Unfortunately, there is no mingw-w64 build for version 9.x here. As Chris suggested, msys2 includes it. But it would be very convenient to have it also here as usual.

This is no longer a bug. Where are you installing mingw from? Use msys2.

We are having the same issue here. Looking forward to see these patches included in a MinGW update.

I would also like to continue using MinGW-w64 standalone builds for using GCC on Windows that I use for simulartaneously testing the Boost libraries using GCC and Clang (and MSVC of course) compilers on Windows. So I loudly join this plea for release of recent GCC releases, especially, for me, the most recent GCC 9 that contains important new constexpr code that provides vital improvements to the code that can be done at compile-time, making a massive run-time improvement (that is NO-time ;-) ) to...
