please provide wheels for Apple Silicon

[sg-s]

i can help with this if you want.

right now other things depend on greenlet, which are broken because there are no wheels for my arch. i've had to download this repo and build the wheel myself and use that.

[Timopheym]

Could you please provide it somewhere please? It's not easy to build it each time as I don't have proper dev. environment with python.h for that... thanks!

i built this using

pip wheel .

and got this:

Successfully built greenlet

looks like everything worked?

greenlet-2.0.3.dev0-cp39-cp39-macosx_10_9_x86_64.whl.zip

can't we use a github action with a runner on apple silicon to automate the build?

Just in case anyone comes here looking for help with 2.0.1 and Ventura throwing all sorts of horrible compilation issue, 2.0.2 fixed it for me.

Hi -

I see the issue is marked completed, are there Apple M1 wheels published now? I dont see anything at https://pypi.org/project/greenlet/#files , were there changes to build infrastructure that have yet to take place on pypi ?

[jamadden]

There have been M1 wheels since January (2.0.2 and 3.0). E.g., greenlet-2.0.2-cp311-cp311-macosx_10_9_universal2.whl

[jamadden]

I wasn't as successful getting wheels published for 2.0 so they may not be there for the full matrix, but they should be for 3.0.

[zzzeek]

Ok which files at https://pypi.org/project/greenlet/#files are that ? We've had huge notes etc on our docs about apple M1 not being available without build tools etc and that would all have to change. I don't see which files there would be the ones but then I don't know what a wheel for M1 looks like. cc @CaselIT

It looks like 3.0.0a1 has macos-arm64 files which id assume are the files. Current released 2.0.2 does not have them

[jamadden]

universal2 is the wheel tag for Mac wheels with both x86_64 and arm code, like the one I linked to for 2.0.2.

[jamadden]

Unfortunately, getting universal2 wheels to build reliably has been problematic on some versions of Python+tooling, hence the sometimes separate arm and x86 wheels. What's even weirder is that some of the wheels tagged x86_64 are, in fact, really universal2 and contain both architectures.

[CaselIT]

@zzzeek I guess the big note on top here https://docs.sqlalchemy.org/en/20/orm/extensions/asyncio.html can be removed

[jamadden]

(I've filled in the matrix for 2.0.2 with specific arm64 wheels to eliminate confusion. I think I've worked out how to only get universal2 wheels going forward.)

[CaselIT]

if you are using cibuildwheel it seems to create two wheels, at least when configured using

[tool.cibuildwheel.macos]
archs = ["x86_64", "arm64"]

don't know if they support universal. I also don't know if there is any advantage in having one file instead of two
