The AUR package for JpegXL support is outdated and does not build. If you need JpegXL support, follow the instructions in the comment I posted to update the PKGBUILD.

Python 2 is deprecated and undesirable. This package needs to be updated to replace it with Python 3. As it stands, the package no longer builds as Python 2 fails to build.

Hydrus no longer builds for me because python2 fails to build. Since arch has now dropped python2 support, is there a way to get rid of the python2 dependency?

Can we get proper XDG in the applied patch for the BASE_DIR?

Example:

BASE_DIR = os.path.join(os.getenv("XDG_DATA_HOME", os.path.expanduser("~/.local/share")), "hydrus")

PySide6 is now the default over PySide2 since Qt6 is now the default: https://github.com/hydrusnetwork/hydrus/releases/tag/v495

@WorldTeacher, it would be my recommendation to remove all packages installed in ~/.local/lib/python3.10, whether by moving it away or by invoking pip for each one. Then the packages you still need can be reinstalled via the AUR or pacman.

@Score_Under, so just to make sure I understand it correctly: I should uninstall opencv-python using pip (as well as the packages located in ~/.local/lib/python3.10) and install them using pamac / pacman? Or did you mean something else?

@WorldTeacher I note that you have opencv installed locally via pip. Just a heads-up, installing anything locally via pip can take priority over system packages and mess with otherwise-working python library installations on your system. I strongly recommend against using local pip installs, and instead anyone wanting to do so should confine those installs to a virtual environment (python -m venv --help).

If you move your ~/.local/lib/python3.10 directory away (e.g. rename it and add ".old" to the end), that will get rid of all locally installed python packages which should either allow you to determine if that really is the problem, or allow you to revert back to a hopefully working state.

For the record, I have python-opencv installed alongside hydrus on my system and it is not a problem.

In version v493-1, the client will not launch when opencv-python is installed on the system. As soon as opencv-python is uninstalled, it works fine. This is the error message it produces in the terminal:

v493, 2022/08/03 18:57:13: hydrus client started QObject::moveToThread: Current thread (0x5636edae12b0) is not the object's thread (0x5636ed9a12e0). Cannot move to target thread (0x5636edae12b0)

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/alexander/.local/lib/python3.10/site-packages/cv2/qt/plugins" even though it was found. This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb, eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx.

@Score_Under Thanks the issue has been solved by switching back

Score_Under commented on 2022-01-02 15:52 (UTC)

@misagh, I've given this a look and it does indeed seem to be true that pyqt5 alone hits on some bugs, so I've put a hard dependency for pyside2 in again.

As much as part of me wants to run on pyqt5 just to find the bugs... :)
