I was digging more on this:

Ubuntu Noble debian packages does not have (for now) libshiboken6-dev and libpyside6-dev which are the compatible version for Qt6. Anyhow you can install this dependencies with pip:

pip install -U shiboken6 pyside6 shiboken6_generator

There is a mismatch of version between pip pyside and shiboken and Qt6 from debian packages.

Ubuntu noble distribute qt6.4.2 but the pip available version for the required packages are 6.7.2, 6.7.1, 6.7.0, 6.6.3.1, 6.6.3, 6.6.2, 6.6.1, 6.6.0.

This package will require also changes on python_qt_binding in particular in cmake/shiboken_helper.cmake

May is not the right time (yet) to port this package?

Required ros-visualization/python_qt_binding#143

After a rebase with conflict resolution (https://github.com/mosfet80/qt_gui_core/tree/fixQT6) I tried the patch on opensuse qt6 and wayland .. it works!

compiled on fedora 42 (only qt6)
