Towards a nix package

[con-f-use]

I'm trying to package mcomix3 for the nix package manager.

I'm having this problem:

Traceback (most recent call last):
  File "/nix/store/x38kx1vv2yhy44hfqhgfz2scpah1vaf5-mcomix3-1.2.1+git20201123/bin/mcomix/run.py", line 116, in run
    require_version('PangoCairo', '1.0')

    raise ValueError('Namespace %s not available' % namespace)
ValueError: Namespace PangoCairo not available
22:39:37 [MainThread] ERROR: You do not have the required versions of GTK+ 3.0 installed.

No idea where it is coming from. I have GTK 3.24.21 installed and pygobject, too.

Please ensure these files installed correctly, and ask packager of your distribution for more help:

girepository-1.0/Atk-1.0.typelib
girepository-1.0/cairo-1.0.typelib
girepository-1.0/Gdk-3.0.typelib

girepository-1.0/Gio-2.0.typelib

Thanks for the info. I'm currently trying to package mcomix3 for NixOS, so I guess, I'm the packager.

I solved the PangoCairo problem and mcomix starts, but in many dialogs or when opening a file it crashes with:

GLib-GIO-ERROR **: 09:54:45.625: No GSettings schemas are installed on the system

Any idea, what schema excatctly might be missing or what could be the problem?

Okay, solved that problem, too - the last remaining thing are the tests.

Are they broken or supposed to work, like at all?

Sorry, I never dive into the test directory (and not well ported to py3 together with mcomix3), so it is not expected working as it was.
