Repairing wheel fails on pypy37 with "This does not look like a platform wheel"

[CaselIT]

Description

I'm trying to migrate sqlalchemy custom wheel build actions to cybuildwheel, and came across this issue when cibuildwheel attemps to build the wheel for pypy3.7 on linux.

Since these are test build they include the tag_build = dev, not sure if it may be related.

Sqlalchemy currently doesn't provide pypy builds so this is not a blocking issue in migrating to cibuildwheel, (and it seems our test suite is somewhat broken on pypy, at least on windows), but it seems worth reporting

btw thanks for automatic the build creation, previously a custom action was used that did basically the same thing (build wheel, install it, test it and publish)

(it may be worth providing a place for the config file link)

Based on checks, it may be some problem with the wheel. The best option for debugging it will be to download the wheel and check its content as this error means a lack of ELF files:

https://github.com/pypa/auditwheel/blob/main/src/auditwheel/wheel_abi.py#L51

You may use CIBW_REPAIR_WHEEL_COMMAND to disable wheel repair steep.

oh ok, the error was not clear to me at all!
Reading the provided code it happen if there are no compiled files in the wheels, and that's indeed the case, since sqlalchemy cython parts are not build for pypy (that will use the pure python fallback)

I would suggest providing a better log, something like This does not look like a platform wheel, no compiled extension found or similar wording

I think this can be closed, thanks for the pointer!

If you have a pure Python fallback, I'd publish a pure Python wheel + CPython platform wheels. You can build the pure Python wheel with build. And the error comes from auditwheel, not us, in this case. :)

Yes, I'll do that. I've provided a PR to auditwheel to hopefully clarify the log message
