MSYS2
What MSYS2 is
MSYS2 is a free, open-source environment for building, installing, and running native Windows software. It is aimed at developers using MinGW-w64 toolchains, Bash, Autotools, and related build tools. Its Pacman package manager installs packages, resolves dependencies, and performs system upgrades, with offline installation supported. The repository contains more than 3,700 pre-built packages. The distribution includes a terminal, Bash, version control systems, utilities such as tar and awk, and build systems including Autotools. Listed native software includes GCC, mingw-w64, CPython, CMake, Meson, OpenSSL, FFmpeg, Rust, and Ruby. Documentation covers terminal setup in Sublime Text, Visual Studio Code, and Zed, plus CI use with GitHub Actions, GitLab, AppVeyor, Docker, and other systems. MSYS2 supports Windows 10 1809+ x86_64 and Windows 10 ARM64, with separate 64-bit requirements for installers and package environments.
