Any plans to publish macos universal2 wheels?

BUG/PROBLEM REPORT / FEATURE REQUEST

I'm currently working on a desktop project that bundles zope.interface. We're doing the required changes to run natively on Apple Silicon processors.

By inspecting the installed files I realized that _zope_interface_coptimizations.cpython-310-darwin.so architecture is only x86_64.

So, as the title says, are there any plans to publish universal2 wheels? Can you recommend any workaround?

What I did:

On a macos intel computer:

$ pip install zope.interface==5.5.2

Then build and package my application.

On a macos apple silicon computer:

$ lipo -archs path/to/zope/interface/_zope_interface_coptimizations.cpython-310-darwin.so

What I expect to happen:

x86_64 arm64

What actually happened:

x86_64

What version of Python and Zope/Addons I am using:

• MacOS 12 Intel (build machine)
• MacOS 14 M1 (client machine)
• Python 3.10.13
• zope.interface==5.5.2

@carlos-villavicencio-adsk Thank you for your report.

You are using a really old version of zope.interface.

With the current release I get on M2 for Python 3.11:

$ bin/pip install zope.interface==6.2
Successfully installed zope.interface-6.2
$ lipo -archs lib/python3.11/site-packages/zope/interface/_zope_interface_coptimizations.cpython-311-darwin.so
arm64

universal2 have build and package selection issues. So we decided to have separate ones for x86 and arm.

Does this answer your question?

[carlos-villavicencio-adsk]

Yes, thanks.

I was able to fix this by combining the two so binaries (x86_64 and arm64) into a fat one using the lipo tool. Now I got it working as expected.

Nice to hear, so I am closing this issue now.
