Ugh! So it looks like this might work if we add all of the cffi dependencies to setup_requires. Unfortunately, this then also means these packages are required for sdist, which should be able to just build the source and doesn’t need to have the dependencies, which would greatly complicate the release creating in github actions (not impossible to do, but would take a bit of work to get fixed up). There is some discussion that build_system is the replacement for setup_requires, but it looks like that gives the same error.

For now, if you re-install pywlroots, but first install cffi, pywayland, and xkbcommon, then it should work. Note that you might need to remove ~/.cache/pip so you re-download and rebuild the packages. We can move this issue over to the pywlroots repo.

Great! I was able to get a fix pushed into pywlroots and a new version cut, so this shouldn’t be a problem moving forward!

Let us know if this continues to be a problem. I’ve moved the underlying problem over to flacjacket/pywlroots#65.

So it looks like this is what is showing up in the pip install log:

  Running setup.py (path:/tmp/pip-install-9tjjy02w/pywlroots_554b3b63490344b1881fe7d0140c9046/setup.py) egg_info for package pywlroots
  Created temporary directory: /tmp/pip-pip-egg-info-1m1fuuph
  Preparing metadata (setup.py): started
  Running command python setup.py egg_info
  /usr/lib/python3.9/distutils/dist.py:274: UserWarning: Unknown distribution option: 'cffi_modules'
    warnings.warn(msg)

That is why we aren’t able to get the cffi module installed. Why this isn’t correctly being handled via the install_requires, I’m not totally sure.

Hmm, I think it should be built when installing with pip. @flacjacket any ideas?

How did you install it? The ffi module needs to be built. This should be done by pip if you used that.

There are a number of dependencies needed for Wayland. See http://docs.qtile.org/en/latest/manual/install/index.html#core-dependencies

That error is because you don’t have pywlroots installed.
