amitie10g/msys2-mingw-w64-toolchain repository overview

⁠MSYS2 MinGW-W64 toolchain Docker image under Windows

This is an attemp to bring several toolchains for MSYS2, under Microsoft® Windows® Server Core⁠ Docker image, intended to be used in my own projects.

⁠Tags

The fillowing toolchains are provided, with the MSYSTEM env properly configured.

• gcc-x86_64 gcc latest provides GCC x86_64 (MINGW64)⁠
• ucrt provides GCC x86_64 (UCRT64)⁠
• gcc-i686 provides GCC i686 (MINGW32)⁠
• clang-x86_64 provides Clang x86_64 (CLANG64)⁠
• clang-i686 provides Clang i686 (CLANG32)⁠
• clang-aarch64 provides Clang arm64 (CLANGARM64)⁠
• clang-x86_64-riscv64 provides Clang riscv64 (CLANG64)⁠
• clang-i686-riscv64 provides Clang riscv64 (CLANG32)⁠
• x86_64-riscv64 provides GCC riscv64 (MINGW64)⁠
• ucrt-x86_64-riscv64 provides GCC riscv64 (UCRT64)⁠
• i686-riscv64 provides GCC riscv64 (MINGW32)⁠
• cross-gcc cross provides Cross GCC (MINGW32)⁠
• cross-clang provides Cross Clang (MINGW32)⁠

Under Windows Server Core versions ltsc2022 and ltsc2019

⁠Usage

MSYS Bash interactive shell (default)

docker run -it -v host-src:container-dest --workdir="container-dest" amitie10g/msys2-mingw-w64-toolchain

x86_64 toolchain using make install

docker run -e MSYSTEM=MINGW64 --volume=host-src:container-dest --workdir="container-dest" amitie10g/msys2-mingw-w64-toolchain make install

i686 toolchain using make install

docker run -e MSYSTEM=MINGW32 -e --volume=host-src:container-dest --workdir="container-dest" amitie10g/msys2-mingw-w64-toolchain make install

Windows CMD interactive shell

docker run -it --volume=host-src:container-dest --workdir="container-dest" amitie10g/msys2-mingw-w64-toolchain cmd

Windows Powershell interactive shell

docker run -it --volume=host-src:container-dest --workdir="container-dest" amitie10g/msys2-mingw-w64-toolchain powershell

If you want to use the MinGW32 environment, you must append C:\msys64\mingw32\bin(under CMD shell) to the PATH environment at runtime, or set in an Entrypoint script.

The default workdir is C:\msys64. Set another workdir is recommended only for runing non-interactive building process like make.

⁠Using this base image

⁠Dockerfile

ARG VERSION=latest
FROM amitie10g/msys2-mingw-w64-toolchain:$VERSION

<your code>

⁠Command line

x86_64 toolchain

docker build --build-arg -t <your tag> .

i686 toolchain

docker build --build-arg VERSION=i686 -t <your tag> .

⁠Packages and dependencies

This image depends on the MSYS2 base image⁠ (Dockerfile⁠), where the following packages are installed:

• mingw-w64-i686-toolchain
• mingw-w64-x86_64-toolchain
• autoconf
• automake
• bison
• diffutils
• flex
• gperf
• intltool
• libtool
• make
• texinfo

⁠Caveats

Due the Windows Server Core base image, this image is HUGE. I'm researching how to use Nano Server instead.

⁠Licensing

• The Dockerfile has been released into the public domain (the Unlicense)

• The MSYS2, MinGW-w64 and the packages included in the container are licensed under several licenses (including the GNU General Public License⁠ and other open source licenses). Please refer to them.

• The Windows container base image usage is subjected to the Microsoft EULA⁠.
