RE: [Python-Dev] MS VC 7 offer
From: Moore, Paul
I've asked on the mingw users list about VC7 compatibility. It's quite possible that the msvcr71.dll EULA conditions will make this a non-starter, though (I don't understand them, but they sound scary...)
FWIW, I just got a reply from the mingw list. Because msvcrt is distributed with the OS, and msvcr7 is not, GPL compatibility becomes an issue. Specifically, mingw exploits a specific clause in the GPL which allows dependencies on "components of the OS". MSVCRT qualifies here, but MSVCR7 doesn't. So I don't think mingw will support building DLLs which use MSVCR7 for the forseeable future :-( Paul.
Specifically, mingw exploits a specific clause in the GPL which allows dependencies on "components of the OS". MSVCRT qualifies here, but MSVCR7 doesn't.
But surely any GPL issues with using mingw apply only to libraries that mingw *itself* depends on, and then only if one is redistributing a work derived from mingw -- not to anything *created* with mingw?

That's my interpretation of the GPL, as well. -- Gerhard
