wxPython 4.2.1 build failed with cython 3.0.8 and sip 6.8.1 #2514

I'm getting the same problem as reported in https://github.com/wxWidgets/Phoenix/issues/2439, building in MacPorts, with the following versions:

wxpython @4.2.1 sip @6.8.1 cython @3.0.8

I get this for python 3.9.18, 3.10.13 & 3.11.7

This probably stopped working in MacPorts ~2 weeks ago (23/12/2023) when the cython version (in MacPorts) was upgraded from 0.29.36 to 3.0.7. Building wxpython also failed against python 3.0.7. The python version in MacPorts was upgraded from 3.0.7 to 3.0.8 yesterday (11/01/2024).

Note, although in MacPorts the source tgz (of wxpython) is (typically) not downloaded directly from PyPI, the sha256 checksum of the MacPorts and the PyPI source tgz's are identical, so it is the same source as provided by PyPI.

For the record, the build error is:

Yes, the fix isn't in wxPython 4.2.1. You either need to pick up this patch: https://github.com/wxWidgets/Phoenix/commit/aeb557d01e7cd37176ebbf0f1ae6d0b53c115378 or use Cython < 3 as a workaround for now.

Great! Thanks for the pointer. I will try out applying the patch, and if that works ask the MacPorts maintainer to officially add the patch to the MacPorts build.
