I want to launch a Qt application in Wayland ivi-shell.

I tried

QT_WAYLAND_SHELL_INTEGRATION=ivi-shell ./hello-qt-quick2 -platform wayland

Expect the Qt application could launch in Wayland ivi-shell.

But failed with the following message

Failed to load shell integration ivi-shell

Anybody knows what to do with it? Thanks so much!

That output is usually what you get when you try to run on a compositor that doesn't support the ivi_application extension.

If you run the application with WAYLAND_DEBUG=1 set in the environment, there should be a line similar to this:

[3318761.478] wl_registry@26.global(19, "ivi_application", 1)

and one that binds to that interface:

[3318761.541]  -> wl_registry@26.bind(19, "ivi_application", 1, new id [unknown]@29)

If it's not there, then your compositor doesn't support the ivi-shell shell integration.

I got some worked thing on Raspberry Pi 3 like this:

  1. Set environment variable

    export XDG_RUNTIME_DIR=$HOME/.xdg

  2. Run Qt5WaylandCompositor

    $ QT_WAYLAND_CLIENT_BUFFER_INTEGRATION=brcm ./ivi-compositor &

  3. Run Qt5 client application

    $ QT_WAYLAND_SHELL_INTEGRATION=ivi-shell ./untitled2 -platform wayland

  • Please note that QT_WAYLAND_CLIENT_BUFFER_INTEGRATION=brcm should not be needed unless you have a broadcom gpu (like the raspberry pi) – bobbaluba Mar 09 '18 at 10:34
