This is something I had planned to do from the start. It was never my preference to use Cygwin, and instead was going to focus on just using the more minimal MSYS libs. However, porting all of Sage's *dependencies* and especially the other CAS's such as GAP and Singular to work natively is extremely non-trivial (as is porting some other software like cysignals, though Vincent Klein has made great progress on that). I looked early on into some of the dependencies and what it would take to port them. I think GAP, for example, would not be *that* hard. But it's still a non-trivial amount of work. One of the biggest hurdles is simply replacing all the uses of fork() throughout Sage and various dependencies with the appropriate alternative, which may vary from case to case depending on how it's being used. If you would like to find funding to pay my salary for the next two to three years I'd be happy to do it. P.S. I would not characterize Cygwin as "ugh-worthy". Cygwin is a tour-de-force of engineering and is the only reason making Sage work on Windows was feasible at all, as well as provide a usable UNIX shell experience along with it. My only serious motivation for moving away from Cygwin would be the performance and stability problems surrounding fork(). It's remarkable that Cygwin is even able to emulate fork() at all, but it's once of its shakiest areas. It would probably help if MSFT open-sourced parts of the WSL, or at least gave documentation and guidance on how to use the undocumented RtlCloneUserProcess interface that is known to exist in the NT kernel but that nobody really knows how to use: https://www.cygwin.com/ml/cygwin/2018-01/msg00201.html -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
