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 as deploys their Pacman packages repository overlay to GitHub Pages environment of this repository. It also serves as a documentation of the necessary steps to build them.

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

Packages Repository Usage

Add the following to the /etc/pacman.conf before any other package repository 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-gcc

to install x64 host MinGW compiler with aarch64-w64-mingw32 target support.

Building Packages Locally

In case one would like to build all the packages locally, there is a build.sh script. It expects that all the dependency repositories are cloned in the parent folder of this repository's folder.

Dependencies Chart

The color of the blocks indicates whether the package recipes exist and/or succeed to build and install. It does not reflect whether they actually work or do not contain severe bugs to resolve.
