Unable to package on Python 3.{10,11,12} with CFFI 1.16 on macOS 14.4 with Clang 15

[mpasternak]

Hello,

TL;DR:

I am unable to build pyheif using python setup.py build (fails on cffi_modules) on my macOS Sonoma 14.4, but everything is fine if I compile by hand (calling python libheif/libheif_build.py then copying _libheif_cffi* from the root dir directly to the virutalenv works fine and gives good results - HEIC files are being open properly).

I will edit this shortly to add a link to my repo which kindly creates a hack for this. Maybe I will even upload some binary packages to PyPI.

Full version:

This looks like setuptools or CFFI setuptools extension bug to me, so this should not be actually reported here. But where? I have no idea, I have no experience of talking to setuptools people, I am posting this in hope "somebody does something" as in contacting some proper maintainer who would show the way, what are we doing wrong. Or, perhaps a version or two passes and somebody fixes this.

This is the build log:
pyheif-0.7.1-build-log-fail-python3.12-macos14.4-libffi1.17.txt

The repo

Please go visit my fork: https://github.com/mpasternak/pyheif

Type make all, see dist directory then.

The temporary fix

When running on macOS, you can try installing binary packages with:

pip install pyheif-iplweb

This will install a versioned package. Version number of the package means: pyheif-iplweb-0.7.1.dev1176. This means it was build from pyheif 0.7.1 and libheif 1.17.6
