The scripts provided by the MinGW-W64 project are designed for building the dual-target(i686/x86_64) MinGW-W64 compiler for i686/x86_64 hosts.

The scripts are distributed under the 'BSD 3' license.

In order to use the scripts provided by the MinGW-W64 project it is needed:

  1. Windows-64bit or Linux + Wine-64bit

  2. Install MSYS2 from: http://sourceforge.net/projects/msys2/ (MSYS2 wiki: http://sourceforge.net/p/msys2/wiki/MSYS2%20installation/)

  3. Get the scripts into '/home//mingw-builds'

cd && git clone <paste correct url>

(see the diff between the 'master' and 'develop' branches, maybe you need the 'develop' branch exactly)

  1. In the MSYS2 file structure delete the '/MinGW' directory.

  2. Delete the paths pointing to any preinstalled MinGW from the 'PATH' environment variable.

  3. Go into the MinGW-builds root directory.

cd && cd mingw-builds
  1. Options:
`--mode=[gcc|python|clang]-version` - what package to build with version.
`--arch=<i686|x86_64>`              - build architecture.
  
`--buildroot=<path>`                - using '<path>' as build directory.
                                      By default used MSYS user home directory.
`--fetch-only`                      - only download all the sources without start building.
`--update-sources`                  - try to update sources from repositories before build.
`--exceptions=<model>`              - exceptions handling model.
                                      Available: dwarf, seh(gcc>=4.8.0 only), sjlj.
`--use-lto`                         - building with using LTO.
`--no-strip`                        - don't strip executables during install.
`--no-multilib`                     - build GCC without multilib support (default for DWARF and SEH exception models).
`--static-gcc`                      - build static GCC.
`--dyn-deps`                        - build GCC with dynamically dependencies.
`--rt-version=<v3|v4>`              - version of mingw-w64 runtime to build.
`--rev=N`                           - number of the build revision.
`--with-testsuite`                  - run testsuite for packages that contain flags for it.
`--threads=<posix|win32>`           - used threads model.
`--enable-languages=<langs>`        - comma separated list(without spaces) of gcc supported languages.
                                      available languages: ada,c,c++,fortran,objc,obj-c++

For more options run: ./build --help

  1. Run:
  `./build --mode=gcc-4.8.1 --arch=i686` for building i686-MinGW-w64
  `./build --mode=gcc-4.8.1 --arch=x86_64` for building x86_64-MinGW-w64
  `./build --mode=gcc-4.8.1 --arch=x86_64 --preload` for preload sources and building x86_64-MinGW-w64
  `./build --mode=gcc-4.8.1 --arch=i686 --exceptions=dwarf` for building i686-MinGW-w64 with DWARF exception handling

For example, during the process of building of the i686-gcc-4.7.2 will be created the following directories:

  <buildroot>/i686-4.7.2-release-posix-sjlj-rev1/build
  <buildroot>/i686-4.7.2-release-posix-sjlj-rev1/libs
  <buildroot>/i686-4.7.2-release-posix-sjlj-rev1/logs
  <buildroot>/i686-4.7.2-release-posix-sjlj-rev1/prefix

For x86_64:

  <buildroot>/x86_64-4.7.2-release-posix-sjlj-rev1/build
  <buildroot>/x86_64-4.7.2-release-posix-sjlj-rev1/libs
  <buildroot>/x86_64-4.7.2-release-posix-sjlj-rev1/logs
  <buildroot>/x86_64-4.7.2-release-posix-sjlj-rev1/prefix

And the sources directory:

  <buildroot>/mingw-sources

The archives with the built MinGW will be created in '/archives/'

At the moment, successfully building the following versions:

  gcc-4.6.2
  gcc-4.6.3
  gcc-4.6.4
  gcc-4.7.0
  gcc-4.7.1
  gcc-4.7.2
  gcc-4.7.3
  gcc-4.8.0
  gcc-4.8.1
  gcc-4.8.2
  gcc-4.9.0
  gcc-4.9.1
  gcc-4.9.2
  gcc-4.9.3
  gcc-5.1.0
  gcc-5.2.0
  gcc-4_6-branch (currently 4.6.5 prerelease)
  gcc-4_7-branch (currently 4.7.4 prerelease)
  gcc-4_8-branch (currently 4.8.3 prerelease)
  gcc-4_9-branch (currently 4.9.4 prerelease)
  gcc-5-branch (currently 5.3.0 prerelease)
  gcc-trunk (currently 6.0.0 snapshot)

Builds also contains patches for building Python 2.7.9 and 3.4.3 versions for support gdb pretty printers. Big thanks for these patches to:
