SK-AM62: PyQt5 on AM62

Hello James,

We do not enable pyqt5 as part of our SDK and our qt packages are simply inherited from the following recipe: https://github.com/meta-qt5/meta-qt5/tree/dunfell. I see a recipe for pyqt5 and my recommendation would be to try enabling it through Yocto: https://github.com/meta-qt5/meta-qt5/blob/dunfell/recipes-python/pyqt5/python3-pyqt5_5.15.1.bb.

Hi Krunal,

In python3-pyqt5_5.15.1.bb, how to make sure that I have enabled pyqt5?

I have seen the meta-qt in the bitbake layer, but how to know if the recipe is enabled or disabled?

Hi James,

In Yocto conf, you could try to do something like this "echo 'IMAGE_INSTALL_append = "  pyqt5"' >> conf/local.conf".

Hi Krunal,

I run the python file on bash and it appears following message:

qt.qpa.wayland: "wl-shell" is a deprecated shell extension, prefer using "xdg-shell-v6" or "xdg-shell" if supported by the compositor by setting the environment variable QT_WAYLAND_SHELL_INTEGRATION
qt. qpa. wayland: xkbcommon not available on this build, not performing key mapping

Where should I set the variable "QT_WAYLAND_SHELL_INTEGRATION" to eliminate the error?

Hi James,

I believe that above is only a warning and not an error. In general, you can do something like the following "export QT_WAYLAND_SHELL_INTEGRATION=<var>".

Hi Krunal,

Even if I ignore "QT_WAYLAND_SHELL_INTEGRATION", the message "qt. qpa. wayland: xkbcommon not available on this build, not performing key mapping" still exists.

Because the GUI has the widget "QLineEdit", I cannot type the word on the edit bar.

When I try to click the edit widget, the terminal appears the error "qt. qpa. wayland: xkbcommon not available on this build, not performing key mapping".

Hi James,

Have you checked with the qt forum for similar issue? Also, maybe it's missing a Yocto package such as "xkbcommon" and we do not support X11 so maybe that library is missing. My recommendation would be to check with the Qt community on the dependencies.
