GCC for Windows 64 & 32 bits


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)

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.


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

It apears as known issue caused by gcc compiler adopting FDIS approved C++11 standard which was later overturned . See details at https://github.com/jtv/libpqxx/issues/336#issuecomment-643859978 Therefore I would like to upgrade to mingw64 version using gcc 4.9.3 but I also bound to run it on ubuntu 14.04 /Trusty so could this be accoimodated with any existing packages?

I realize I didn't mention an important detail. I'm using g++ 8.1.0, and stalled it using chocolatey.
