![]() ![]() This behavior can be controlled by setting the variable MSYS2_PATH_TYPE before starting a shell or using a correct argument when executing the launcher script. PATHįor optimal usage, MSYS2 automatically strips your PATH environment variable, essentially only leaving C:\Windows\System32 and few others. Do not set MSYSTEM outside of the shells, because that will also break things. The exception is using mingw subsystems from pure Windows, which shouldn't require any special environment apart from an entry in PATH. Without the correct environment, various things may and will (sometimes silently) break. Bash in turn sources /etc/profile which sets the environment depending on the value of MSYSTEM. The launchers set the MSYSTEM variable and open a terminal window ( mintty) with a proper shell ( bash). These shells can be invoked using launchers in the MSYS2 installation directory or using the shortcuts in the Windows Start menu. ShellsĮvery subsystem has an associated "shell", which is essentially a set of environment variables that allow the subsystems to co-operate properly. There are also cross compiler toolchains with host=-w64-mingw32 in mingw-w64-cross-toolchain, but these are of limited use because there are no library packages for them. target=host) compiler toolchain, in mingw-w64-i686-toolchain, and mingw-w64-x86_64-toolchain. This part builds on the Cygwin project.Įach of the subsystems provides its own native (i.e. Some effort is made to have the programs work well with native Windows programs, but it's not seamless. These programs live in a virtual single-root filesystem (the root is the MSYS2 installation directory). The msys2 subsystem provides an emulated mostly-POSIX-compliant environment for building software, package management, and shell scripting. This part builds on the MinGW-w64 project. These programs are built to co-operate well with other Windows programs, independently of the other subsystems. The mingw subsystems provide native Windows programs and are the main focus of the project. MSYS2 consists of three subsystems and their corresponding package repositories, msys2, mingw32, and mingw64. 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.īoth 32-bit and 64-bit variants exist and receive mostly the same level of support. That means Bash, Autotools, Make, Git, GCC, GDB., all easily installable through Pacman, a fully-featured package manager. It provides a Unix-like environment, a command-line interface and a software repository making it easier to install, use, build and port software on Windows. MSYS2 is software distribution and a building platform for Windows. ![]()
