Hello, thank you for making such a great project open source! I have an issue when installing pywlroots on OpenSuse. I've succsessfully installed the py packages cffi, cairocffi and libraries libwlroots, libwlroots-devel, libxkbcommon and libxkbcommon-devel. I've installed the package inside a virtual environment and get the following error:

  note: This error originates from a subprocess, and is likely not a problem with pip.

I suppose it its a linking problem but I am unable to find the correct solution. Thank you for your help.

I guess the libxkbcommon-devel package is missing. What's the result of 

zypper search -i libxkbcommon

In addition, you're using the virtual environment not correctly. If you created the virtual environment in .venv you'll have to activate it:

source .venv/bin/activate

After the activation, you can use pip without the .venv/bin path:

pip install pywlroots

Complete, minimal example how to create a venv and install pywlroots:

mkdir test-pywlr
cd test-pywlr
python -m venv .venv
source .venv/bin/activate
pip install pywlroots

Thank you for helping me out. zypper search -i libxkbcommon returns:

By activating and using the environment correctly nothing changes. The error persists.

Which SUSE version do you use?

I am using opensuse Tumbleweed.

opensuse Tumbleweed.

Thanks. I can confirm the issue, I just installed Tumbleweed in a VM and I get the same error.

Unfortunately, I'm not familiar with OpenSUSE Tumbleweed, so I can't really help you.

I think the python-xkbcommon project is the right contact for the problem, because the installation (without Qtile and without pywlroots and without pywayland) of

pip install xkbcommon

fails.

Does Tumbleweed perhaps have a package like python3-xkbcommon that you can install globally with zypper so that the lib no longer needs to be installed with pip?

Sorry I can't help, but I would have to spend too much time getting to grips with OpenSUSE.

SortedShuffle commented 7 months ago

Super! Thank you for your time and help! I will try asking python-xkbcommon. Have a great Sunday.

heuer commented 7 months ago

No problem.

Please close the issue here, this seems to be an OpenSuse issue that does not directly affect pywlroots, if I understood https://github.com/sde1000/python-xkbcommon/issues/18 correctly.

SortedShuffle commented 7 months ago

Linking /usr/include/libxkbcommon/xkbcommon to /usr/include/xkbcommon solved the issue. Have a great day!
