gschema and desktop files not copied during setup

[user234683]

Specifically, the files apps.volctl.gschema.xml and volctl.desktop in the data_files in setup.py are not copied to their correct locations during setup. This results in (volctl:10047): GLib-GIO-ERROR **: 21:25:05.356: Settings schema 'apps.volctl' is not installed. I fixed the issue by copying the files manually.

Since the setuptools docs say that data_files are relative to either site.USER_BASE or sys.prefix, I checked these values in a python interpreter. They are /home/[username]/.local and /usr respectively. I checked the directories relative to both of these locations and the files were not copied. I also checked the standard GSettings schema directories listed in the XDG_DATA_DIRS environment variable and did not find the schema file in them.

Environment: Debian Buster 10.2.0, XFCE 4.12, Python 2.7.16, setuptools 40.8.0 (installed from the python-setuptools 40.8.0-1 debian package).

Trace/breakpoint trap

This setuptools issue might be related since I noticed that it created a .egg file in /usr/local/lib/python2.7/dist-packages. I'm new to Linux so I might be missing something obvious.

Python 2 is not maintained after January 1, 2020. Could you try again using a recent version of Python?

Close due to inactivity.

@buzz This problem still happens with python 3.9.2. python3-setuptools version: 52.0.0-4

This is expected behavior.

As far as I know setuptools won't copy schema files. You're doing a manual installation, so you need to take care of this yourself. It's also stated explicitly in the README.md.

If someone would maintain a Debian package for volctl, Debian packaging would take care of this. I won't be able to maintain such a package as I'm not a Debian user.
