Adding Linux and Mac ARM wheels #104
Conversation

@jcrist, what do you think? |
|
Thanks @cjermain! Apologies for the delay here - it looks like there are some test failures on the new architectures. I'm not sure what's going on - hopefully will find some time to debug before the next release. If you're interested in debugging here, I'd welcome the help, though so far this has been mostly a single-dev codebase and the internals are mostly undocumented. |
Updating ci_arm_wheels branch
|
It looks like the CI issues were related to 2 changes in the main branch since I forked. I've merged upstream into this, and it would be great to kick off the builds again. |
|
It looks like there are still some errors when testing the Linux ARM wheel: |
|
After testing with the other architectures, it looks the only issue is with aarch64 for Linux. If we only want MacOS for now, we could come back to Linux aarch64 later. |
|
Thanks @solsen2142! I'm hoping to run this on a Linux ARM VM on top of a Mac M1 chip, so for me the Linux build is a priority. |
Some ARM compatibility fixes. The main issue here was that C leaves it up to the implementation whether `char` is a signed or unsigned type. In x86 systems it's generally a signed type, but on linux ARM it's unsigned. OSX ARM defines it as a signed type for compatibility with x86 OSX.

Thanks for your work here @cjermain - I've pushed up a patch that should (hopefully) fix the linux ARM builds. The main issue was that apparently C leaves it up to the implementation whether |
|
Tests are green, merging. Unfortunately, this makes the linux builds ~8x slower. I'll push a followup PR to trim down the builds for non-releases. We only really need to test on linux once for every python version + one build on aarch64 to catch architecture-specific bugs. |
This resolves #103 by adding steps for Linux and Mac ARM wheels in the CI build. I also bumped the version of pypa/cibuildwheel to v2.4.0.

I don't have a great way of testing this. 馃槃
