I think anyone trying to port Sage's dependencies, in full, to work "natively", no matter how technically competent, will find themselves quickly in over their head just in terms of overhead. Using a POSIX-style toolchain like the MinGW tools is typically easier; I used to maintain builds of some Python projects on MSVC, but it was an enormous extra effort and once I stopped doing it, I don't think anyone else did. Plus dealing with upstream is a huge pain so you have to be prepared to maintain non-trivial patches forever. The true can be said with Cygwin as well sometimes, albeit usually less so. Most Cygwin-related patches tend to be one-or-two liners, though as my efforts in trying to get CPython fully supported on Cygwin show, just porting one project (especially when it's one as non-trivial as CPython) can take up all of one person's time. So I certainly support such efforts and would like to help out. It's just a daunting task. On the conda end of things one thing I've wanted to do is port Cygwin to conda (and vice-versa) so that packages built for Cygwin can be installed with conda. > On Tue, Jan 22, 2019 at 5:15 PM Dima Pasechnik <dimp...@gmail.com> wrote: >> >> On Tue, Jan 22, 2019 at 10:34 PM deSitter <antimatter3...@gmail.com> wrote: >> > >> > Hello all, >> > >> > I am interested in creating a native Windows port completely independent >> > of the ugh-worthy Cygwin.
