One can compile the codebase using the MS compiler (given a suitable environment, and setting the right Makefile flags), but that may not be what you were thinking of. The Windows team recently decided that the older Msysgit approach should be retired (can't find the link just now) and a new approach based on Msys2 started (http://git-for-windows.github.io/ and https://github.com/git-for-windows/git/wiki/FAQ). This is nearing completion. Meanwhile I have been working on fixing the msvc-build script, which can produce a git.sln and associated files (targeted originally at VS2008), and is now at the 'Validate this with the Windows guys' stage (http://marc.info/?l=git&m=143750907804881&w=2 et.seq.). My code, for the new G4W SDK, has been rebased from the msygit version, and is now at https://github.com/git-for-windows/git/pull/256 Does that help for creating an IDE compilable version? Also, many thanks for yournote about the new VS Community edition (I'm still mainly working on an XP notebook for ease of carry). As an open community of independently minded folks it can tae a time to gel around a reasonably common approach, especially as Git will always be primarily focussed on Linux (it **is** the Linux (Linus's) VCS!). > >>> From: jacob.keller@gmail.com >>> On Sat, Jul 25, 2015 at 11:23 PM, Dangling Pointer >>> wrote: >>>> Hello, >>>> >>>> In my understanding, the ratio between the mere consumers of git on >>>> Windows vs. people who compile git for Windows is 100,000 : 1.
