Description:
libkate upstream has not been active lately. The latest commit was over 8 years ago and Jelle van der Waa needs to patch the autotools build to work. libkate is a hard dependency of `libtiger`, which is a hard dep of `gst-plugins-bad`, which is a hard dependency of `cheese`, which is a hard dependency of `gnome-control-center`. libkate also provides the remuxing / editor tool `KateDJ`, which is written in Python 2 and python2-wxpython3. It is hard to find an example file for it to work, it needs an ogg container with kate subtitles. Here is an example file to test it: https://cweiske.de/tagebuch/demo/embedded-lyrics/countdown-sync-oggz.ogg Source: https://cweiske.de/tagebuch/embedded-lyrics.htm I ported KateDJ to Python 3 and wxpython4: https://gitlab.com/lubosz/kate/-/tree/python3 I also provided an AUR package for it: https://aur.archlinux.org/packages/libkate-python3-git/ The problem is that KateDJ is already broken in it's current form, since it is missing parameters for the kateenc command it wraps. This results in a warning "warning: no category defined" from kateenc, and is fatal in KateDJ which fails if kateenc returns anything. This is the case for the currently packaged Python 2 version as the Python 3 port provided by myself. I could also probably fix this one error, but it seems that upstream has already given up on this tool as well. TL;DR: The broken tool KateDJ from libkate is the reason GNOME depends on Python 2. I would suggest to remove KateDJ from this package, and provide another package with this broken tool if you decide to continue carrying it around. I have created a branch which removes KateDJ from the build and the code from the repo completetely. https://gitlab.com/lubosz/kate/-/tree/no-katedj https://aur.archlinux.org/packages/libkate-git/ Both my branches are based on libkate master, the current Arch package uses the latest tag, which is a couple of commits behind. Also the optdepend in the libkatepackage is incorrect. It should be `python2-wxpython3` and not `wxpython`, which does not exist anymore. Side note: kate needs to be built with the following LD_FLAGS so linking works: LDFLAGS="-Wl,--as-needed" ./autogen.sh This is already done in the default LD_FLAGS in makepkg.conf, but you need it if you build it by hand. I should also contact upstream about this, let's see if its easy to fix this tool or if they decide to remove it as well and tag a release on libkate. Additional info: * Version 0.4.1-6 Steps to reproduce: * Install the `gnome` package group. |

The package is orphaned, so assigning to maintainers of the reverse-dependencies.
