This repo packages the build tools needed to compile c and c++ source when using Windows Rubies with GitHub Actions.
Publicly available Windows Rubies are built with the MSYS2 system, which provides a bash shell, compilers and tools, and various packages. Windows Rubies 2.4 thru 3.0 use the MSYS2 tools refered to as 'mingw64', which compile using legacy Windows libraries. Windows Rubies 3.1 and later use 'ucrt64', which use newer Windows libraries.
Below summarizes the default MSYS2 installations on Actions Windows images:
| Actions Image |
MSYS Base |
MSYS Build Tools |
mingw64 gcc & tools |
mingw64 packages |
ucrt64 gcc & tools |
ucrt64 packages |
|---|---|---|---|---|---|---|
| 2022 and later | Yes | No | No | No | No | No |
| 2016, 2019 | Yes | Yes | Yes | Some | No | No |
Six package files are stored in a GitHub release, and are used by ruby/setup-ruby. They are:
-
msys2.7zThe base msys2 installation on Actions Windows images contains a minimal set of bash tools, and no shared build tools. Code updates the MSYS2 files, and saves only updated files to the 7z. All Ruby Windows releases from version 2.4 and later use these tools. -
mingw64.7zThis contains the mingw64 gcc chain and any packages needed to build Ruby. This has OpenSSL 1.1.1 installed, as of 26-Apr-2024, 1.1.1.w. Normal Ruby Windows releases from version 2.4 thru 3.0 use these tools. -
mingw64-3.0.7zThis contains the mingw64 gcc chain and any packages needed to build Ruby. The MSYS2 OpenSSL 3.3.z package is installed. The mingw Ruby master build is the only build that uses this. -
ucrt64.7zThis contains the ucrt64 gcc chain and any packages needed to build Ruby. This has OpenSSL 1.1.1 installed, as of 26-Apr-2024, 1.1.1.w. Ruby version 3.1 is the only release that uses this. -
ucrt64-3.0.7zThis contains the ucrt64 gcc chain and any packages needed to build Ruby. The MSYS2 OpenSSL 3.3.z package is installed. Ruby 3.2, head, & ucrt builds use this. -
mswin.7zThis contains files needed to compile Windows Ruby mswin builds. It contains libffi, libyaml, openssl, readline, and zlib, built with the Microsoft vcpkg system. This contains OpenSSL 3.0.z.
The code installs the packages with ruby/setup-ruby, then updates the MSYS2 and vcpkg packages. If any packages have been updated, it creates a new 7z file and updates the package in the release.
