MSYS2 GNU Toolchains

MSYS2 may refer to:

• MSYS2 runtime (msys-2.0.dll) available as Base Package: msys2-runtime - MSYS2 Packages package,

• either native or cross-compilation aarch64-pc-msys the target https://linaro.atlassian.net/wiki/spaces/WOAR/pages/28802842658 consisting of several packages from MSYS2 distribution,

• or the whole distribution of software depending either on MSYS2 or MinGW runtime in form of MSYS2 packages available atMSYS2.

This project’s scope is limited to providing both native and cross-compilation (Windows x64 → Windows Arm64) toolchains in form of several MSYS2 packages enabling the community to port all the packages depending on MinGW runtime to aarch64-w64-mingw32 target and all the remaining packages depending on MSYS2 runtime to aarch64-pc-msys target.

The MSYS2 runtime itself is a friendly fork of https://linaro.atlassian.net/wiki/spaces/WOAR/pages/29484384264 differing only by a small set of patches, mostly doing the rebranding and minor environment changes or fixes so it’s out of the scope of this project so refer there for the details.

The Arm64 porting of MSYS2 toolchains is happening at GitHub - Windows-on-ARM-Experiments/msys2-woarm64-build: Workflows and build scripts for Windows on Arm64 MSYS2 toolchains packages for `aarch64-w64-mingw32` target.

The Windows x64 host, aarch64-w64-mingw32 target cross-compilation toolchain is already available as set of packages in MSYS2 overlay repository at GitHub - Windows-on-ARM-Experiments/msys2-woarm64-build: Workflows and build scripts for Windows on Arm64 MSYS2 toolchains packages for `aarch64-w64-mingw32` target.

The Windows Arm64 host aarch64-w64-mingw32 target native toolchain is being finalized and will be available soon from the same MSYS2 packages repository.

Most of the work with porting the packages forming the native aarch64-pc-msys target toolchain has been already done as well but this work has been paused because of unavailability of the https://linaro.atlassian.net/wiki/spaces/WOAR/pages/29484384264. Once resumed, there will be a necessity to update all the changes already done to align with the upstream changes happening meanwhile.

Finalizing porting of the native aarch64-w64-mingw32 target toolchain packages.

Upstreaming of both the cross-compilation and the native aarch64-w64-mingw32 target toolchain packages ports.

Once https://linaro.atlassian.net/wiki/spaces/WOAR/pages/29484384264 will be available, finalizing and upstreaming the aarch64-pc-msys target toolchain packages ports.
