First, I want to know if this explanation helps: Cygwin provides a lot of packages allowing (and with the goal of) easy building of POSIX software on Windows. It also provides few packages (mingw-w64-*) additionally allowing building of native Windows software, but it's not really important to them. Imagine MSYS2 is a Cygwin with swapped priorities. Our goal is easy building of native Windows software and we have a lot of packages there, but we also (need to) have some packages for building POSIX software, but it's important for us to expand these repositories. I'd really like to know your feedback on this paragraph. If it did help, I'll include it on the wiki.

Cygwin provides a massive package repository, including a lot of software that is hard to port to native Windows (i.e. mingw-w64). The idea is that the POSIX-emulated part of MSYS2 is just a necessary evil to allow compiling native software. Even if it was not the case though, since MSYS2 isn't just a clone of Cygwin (differences in the runtime, different package manager), we can't simply use their repository nor we can easily use their build recipes to build our own. A single project combining the strengths of both Cygwin and MSYS2 would be awesome, but that's distant, possibly unattainable future. > I am confused because both msys2 and cygwin provide the gnu compiler > collection helping linux developers to code just once and simply compile > again for windows os'(32-bit or 64-bit) binaries. I assume you mean the POSIX-enabled gcc. In that case, my answer is that MSYS2 provides this toolchain, but doesn't encourage its use. The set of available library packages for this subsystem is very small to really allow "simply compiling again for Windows" anyway. -- David Macek
