Oops. Missed that, thank you. Will fix ASAP.

The package still seems to have a dependency on python-setuptools.

My bad, I accidentally removed it from makedepends when switching to python-build.

The package still seems to have a dependency on python-setuptools.

I get:

File "/usr/lib/python3.12/site-packages/pyproject_hooks/_impl.py", line 402, in _call_hook
    raise BackendUnavailable(pyproject_hooks._impl.BackendUnavailable: Cannot import 'setuptools.build_meta')

ERROR Backend 'setuptools.build_meta' is not available.

Thank you @ravenexp for reporting and for the proposed patch. Your changes appear to work. Before pulling them, first I would like to carefully go through the raised Conan issue to avoid any future gotchas. In particular, it seems we will be able to package 2.4.1 using the --wheel flag, thanks to your comments in their issue tracker.

Upstream issue related to the comment below: https://github.com/conan-io/conan/issues/16436

I tried switching to the PEP 517 packaging procedure as described here:

https://wiki.archlinux.org/title/Python_package_guidelines#Standards_based_(PEP_517)

and it seemed to help to resolve the issue as long as the recommended --wheel flag is NOT used with python -m build. My patch is below:

conan-2.4.0-1 packages and installs all its unit tests. It's hardy the intended behavior.

Thank you FirstAirBender for handling the 2.3.2 in my absence and for unborking the detached HEAD state.

Package seems broken due to missing dependency:

Ah I figured it out. This is due to recentish upgrade to Python 3.12. Various AUR packages I have, have not been rebuilt for 3.12, so site-packages dir still in /usr/lib/python3.11, which can't be used/not-found by 3.12. I'll go rebuild a lot of things..

@suridaj: The AUR git repo is in a detached HEAD state. A solution is git switch -c master HEAD && git push origin master within a fresh clone of ssh://aur@aur.archlinux.org/conan.git (this is to avoid potential issues with a broken local repo).

Sorry for not answering earlier. I am currently without access to my Arch machine. Will try to fix this ASAP.
