We cannot remove numpy.distutils, so that separate package may be needed for cross-compilation but we don't need to use it in NumPy itself. >From a high level: being able to cross-compile would be great. However long-term we can hopefully put everything in setuptools, so I'd like the changes now to be as non-invasive as possible. > Kevin > > > On Sun, Oct 25, 2020, 09:23 Matti Picus <matti.pi...@gmail.com> wrote: > >> >> On 10/25/20 10:46 AM, Dustin Spicuzza wrote: >> > I took a first stab at it, and... surprise, surprise, there were a few >> > more warts than I had originally expected in my initial survey.
