Software Distribution and Building Platform for Windows

MSYS2 is a collection of tools and libraries providing you with an easy-to-use environment for building, installing and running native Windows software.

It consists of a command line terminal called mintty, bash, version control systems like git and subversion, tools like tar and awk and even build systems like autotools, all based on a modified version of Cygwin. Despite some of these central parts being based on Cygwin, the main focus of MSYS2 is to provide a build environment for native Windows software and the Cygwin-using parts are kept at a minimum. MSYS2 provides up-to-date native builds for GCC, mingw-w64, CPython, CMake, Meson, OpenSSL, FFmpeg, Rust, Ruby, just to name a few.

To provide easy installation of packages and a way to keep them updated it features a package management system called Pacman, which should be familiar to Arch Linux users. It brings many powerful features such as dependency resolution and simple complete system upgrades, as well as straight-forward and reproducible package building. Our package repository contains more than 2000 pre-built packages ready to install.

For more details see 'What is MSYS2?' which also compares MSYS2 to other software distributions and development environments like CygwinWSLChocolateyScoop, ... and 'Who Is Using MSYS2?' to see which projects are using MSYS2 and what for.


  • Download the installer: msys2-x86_64-20210725.exe

    Verify with SHA256 checksum 7e055b71306e64192e2612f959f54ae99a5cf57186206ac702d113ef00ba35c0 or GPG signature by 0xf7a49b0ec.

  • Run the installer. MSYS2 requires 64 bit Windows 7 or newer.

  • Enter your desired Installation Folder (short ASCII-only path on a NTFS volume, no accents, no spaces, no symlinks, no subst or network drives, no FAT).


  • When done, tick Run MSYS2 now.


  • Update the package database and base packages. Unless your setup file is very recent, it will take two steps. First run pacman -Syu:

    Code: Select all

    $ pacman -Syu
    :: Synchronizing package databases...
     mingw32                        805.0 KiB

     mingw64                        807.9 KiB
     mingw64.sig                    438.0   B
     msys                           289.3 KiB

  • Run "MSYS2 MSYS" from Start menu. Update the rest of the base packages with pacman -Su:

    Code: Select all

    $ pacman -Su
    :: Starting core system upgrade...
     there is nothing to do
    :: Starting full system upgrade...

  • Now MSYS2 is ready for you. You will probably want to install some tools and the mingw-w64 GCC to start compiling:

    Code: Select all

    $ pacman -S --needed base-devel mingw-w64-x86_64-toolchain
    warning: file-5.39-2 is up to date -- skipping
    [... more warnings ...]
    :: There are 48 members in group base-devel:

  • To start building using the mingw-w64 GCC, close this window and run "MSYS MinGW 64-bit" from Start menu. Now you can call make or gcc to build software for Windows.

  • Check out the introduction page to learn which Start menu item to use when and which packages to install. Take look at Detailed MSYS2 install guide for troubleshooting and additional details on how to keep your MSYS2 up-to-date.
