Can't find QT6 inserts to satisfy Wayland

RonLinmd

To all:

I am running the following:
Windows11 Pro
WSL2
Ubuntu 22.04.4 LTS
from PyQt6 import QtCore 6.7.0
from PyQt5 import QtCore 5.15.8

I can make this run string work: QT_QPA_PLATFORM=xdb openmc-plotter
So I know the path statement is correct, and the openmc-plotter app works.
I would like to have this ( and other apps) work with the Wayland insert.

Since the $HOME/anaconda3/lib/qt6/plugins/platforms/ folder did not contain land-generic.so or libqwayland-egl.so,
I copied versions from other locations under a QT6 heading directory, into this folder.

When I execute this string, QT_QPA_PLATFORM=Wayland openmc-plotter
I get the following:

qt.core.plugin.loader: In $HOME/anaconda3/lib/qt6/plugins/platforms/libqwayland-generic.so:
Plugin uses incompatible Qt library (6.7.0) [release]
qt.core.plugin.loader: In $HOME/anaconda3/lib/qt6/plugins/platforms/libqwayland-egl.so:
Plugin uses incompatible Qt library (6.7.0) [release]
qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in "$HOME/anaconda3/lib/qt6/plugins/platforms"
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: minimal, offscreen, vnc, linuxfb, xcb.

How can I get versions of libqwayland-generic.so and libqwayland-egl.so that will solve this dependency?

Thanks

Hi,

Just copying my answer to your other post:

From a quick search, I think you need to install the qt6-wayland package from conda.

Thanks for the response. This response did work for Anaconda-Navigator. However, it doesn't appear to have worked for a different app.

QT_QPA_PLATFORM_PLUGIN_PATH=$HOME/anaconda3/pkgs/qt6-wayland-6.7.0-h6af8810_0/lib/qt6/plugins/platforms QT_QPA_PLATFORM=wayland-egl openmc-plotter
qt.qpa.plugin: Could not load the Qt platform plugin "wayland-egl" in "$HOME/anaconda3/pkgs/qt6-wayland-6.7.0-h6af8810_0/lib/qt6/plugins/platforms" 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.

I've tried uninstalling openmc-plotter and reinstalling with conda, but it has not fixed the issue. Openmc-plotter works when
QT_QPA_PLATFORM=xcb.

Any suggestions?
Thanks again.

Start the application with the QT_DEBUG_PLUGINS environment variable set to 1 to see why it fails to load.
