MSYS2 WoArm64 Packages Build and Repository

This repository contains GitHub Actions workflows for building MinGW and MSYS2 toolchains with aarch64-w64-mingw32 and aarch64-pc-msys targets inside MSYS2 environment and deploys their Pacman packages overlay repositories to GitHub Pages environment of this repository. It also serves as a documentation of the necessary steps to build them.

The actual MSYS2 packages recipes dwells in woarm64 branches of Windows-on-ARM-Experiments/MSYS2-packages repository. Please report any issue related to packages build to this repository's issues list. The actual GCC, binutils, and MinGW source codes with the necessary aarch64-w64-mingw32 target changes are located at Windows-on-ARM-Experiments/gcc-woarm64, Windows-on-ARM-Experiments/binutils-woarm64, and Windows-on-ARM-Experiments/mingw-woarm64, resp. Please report any issues related to outputs of the toolchain binaries to Windows-on-ARM-Experiments/mingw-woarm64-build repository's issues list.

Packages Repository Usage

Add the following to the /etc/pacman.conf before any other package repositories specification:

[woarm64]
Server = https://windows-on-arm-experiments.github.io/msys2-woarm64-build/$arch
SigLevel = Optional

Run:

pacman -Sy

to update packages definitions.

Run:

pacman -S mingw-w64-cross-mingwarm64-gcc

to install x86_64-pc-msys host MinGW cross toolchain with aarch64-w64-mingw32 target support.

Building Packages Locally

In case one would like to build all the cross-compilation toolchain packages locally, there is a build.sh script. It expects that the Windows-on-ARM-Experiments/MSYS2-packages package recipes repository is already cloned in the parent folder of this repository's folder and it must be executed from MSYS environment.

MingGW Cross-Compilation Toolchain CI

The mingw-cross-toolchain.yml workflow builds x86_64-pc-msys host, aarch64-w64-mingw32 target cross-compilation toolchain packages:

MSYS2/Cygwin Toolchain Porting

Work on native aarch64-pc-msys, resp. aarch64-pc-cygwin, toolchain is in progress. First iteration taken is to provide x86_64-pc-msys host, aarch64-pc-msys target cross-toolchain that will then eventually build the aarch64-pc-msys native toolchain. The current status of the cross-toolchain can be visualized by the following chart:
