After installation you will need to perform some additional tasks yourself to ensure your Min GW applications will run.
Primarily intended for use by developers working on the native MS-Windows platform, but also available for cross-hosted use, (see note below -- you may need to follow the "read more" link to see it), Min GW includes: 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 Min GW, for porting of many Open Source applications to the MS-Windows platform; a light-weight fork of Cygwin-1.3, it includes a small selection of Unix tools, chosen to facilitate that objective.
MSYS2 and MSYS2 (Minimal SYStem 2) is an independent rewrite of MSYS, a (command-line) shell for development usage, and based on modern Cygwin (POSIX compatibility layer) and Min GW-w64 (from "Min GW-builds"), with the aim of better interoperability with native Windows software.
It includes: MSYS2-shell and Min GW-w64 Win32 shell & Min GW-w64 Win64 shell.
MSYS2 is a complete opensource development environment shell solution system.
It can obtain related all toolchains & dependency packages from "Min GW-builds" and MSYS2 REPO, for compiling/building other software.
A new version of GCC or library X is available and I can't wait to use it; when will a prebuilt package be ready for download?
We are all busy people with priorities to fulfill including hobbies.
Min GW, being Minimalist, does not, and never will, attempt to provide a POSIX runtime environment for POSIX application deployment on MS-Windows.
If you want POSIX application deployment on this platform, please consider Cygwin instead.
Colin Peters authored the initial release in 1998, consisting only of a Cygwin port of GCC.
