MSYS2 is a software distro and building platform for Windows

At its core, it is an independent rewrite of MSYS, based on modern Cygwin (POSIX compatibility layer) and MinGW-w64 with the aim of better interoperability with native Windows software. It provides a bash shell, Autotools, revision control systems and the like for building native Windows applications using MinGW-w64 toolchains.

It features a package management system, Pacman, to provide easy installation of packages. It brings many powerful features such as dependency resolution and simple complete system upgrades, as well as straight-forward package building.
