Home of the MinGW, MSYS and mingwPORT Projects

MinGW, a contraction of "Minimalist GNU for Windows", is a port of the GNU Compiler Collection (GCC), and GNU Binutils, for use in the development of native Microsoft Windows applications. Offered in easily installed binary package format, for native deployment on MS-Windows, or user-built from source, for cross-hosted use on Unix or GNU/Linux, the suite exploits Microsoft's standard system DLLs to provide the C-Runtime and Windows API. It is augmented by additional function libraries for improved ISO C-99 compatibility, and further, by community supported add-on tools and libraries, many pre-built, many more in the form of "mingwPORTs", to be built by the end user.

MinGW provides a complete Open Source programming tool set which is suitable for the development of native MS-Windows applications, and which do not depend on any 3rd-party C-Runtime DLLs.

MSYS, a contraction of "Minimal SYStem", is a Bourne Shell command line interpreter system. Offered as an alternative to Microsoft's cmd.exe, this provides a general purpose command line environment, which is particularly suited to use with MinGW, for porting of many Open Source applications to the MS-Windows platform; it includes a small selection of Unix tools, chosen to facilitate that objective, and using it is a necessary prerequisite for building mingwPORTs.

mingwPORTs are user contributed additions to the MinGW software collection. Rather than providing these "add-ons" as precompiled binary packages, they are supplied in the form of interactive Bourne shell scripts, which guide the end user through the process of automatically downloading and patching original source code, then building and installing it. Users who wish to build any application from a mingwPORT must first install both MinGW and MSYS.

Several project affiliated Mailing Lists are available, which you are encouraged to join, and in which you are invited to participate. In particular, there is a general discussion list, mingw-users@lists.sourceforge.net, for general questions: please use it; do not create wiki pages, or add comments to wiki pages, to ask questions. Information for sign-up, and links to the archives can be found on the mailing lists page. You may search the archives using the "Mail List Search" form found on the right hand side of every http://www.mingw.org page.
