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 8 has been released

v8.0.0: 2020-09-18

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
  • wdm and ddk updates by Zebediah Figura
  • UCRT for Windows Store Apps (-lucrtapp) by Martin Storsjö
  • Audioclient and ActivateAudioInterfaceAsync API updates by Liu Hao
  • DirectX SDKs are now always installed
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.

Tools

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

Hello, I think it would be better to keep them for gcc at the place they are ... gcc is sadly a bit picky about the place for it ... as VC is too. But why not using macro specific for gcc, and another set for VC, which are placed at their most beloved places? Btw great that you try to port winpthread for VC :) Cheers, Kai Am Fr., 27.

You can find stand-alone fresh versions here: http://winlibs.com/ or you can use msys2. gdb with python is here: https://github.com/ssbssa/gdb

These builds do not support multi-arch (-m32/-m64). To build x64 apps, you need to install the x86_64 versions. This is a technical limitation mainly due to how windows searches for, loads, and installs runtime support dlls for compiled programs. It is possible to build multi arch but to be honest it's way more trouble than it's worth from a support perspective.

I must be doing something monumentally stupid. I installed MinGW-w64 a few hours ago, from Sourceforge, using all the defaults. I ran the standard script, putting C:\Program Files\mingw-w64\i686-8.1.0-posix-dwarf-rt_v6-rev0\mingw32\bin in the PATH. I get gcc version gcc (i686-posix-dwarf-rev0, Built by MinGW-W64 project) 8.1.0 g++ version is the same. I run g++ -m32 hello.cpp -o hello.exe and the right things happen. But g++ -m64 hello.cpp -o hello.exe gets cc1plus.exe: sorry, unimplemented: 64bit...

the 'latest' gcc version of MinGW-w64 - for 32 and 64 bit Windows is 8.1.0, which was released in 2018. And where is the next gcc release?

This seems to have been fixed for _stat and _wstat but not for _wstat64. Is that intentional?

I moved the -windows and -console arguments from the compiler options to the linker options and everything was resolved. And under Windows like and so worked :)
