[Interest] How to run Qt application on Wayland-ivi-extension

Thu Dec 7 06:23:35 CET 2017

Hi Macieira,

First of all, thank you for your time.

I followed your advice, after launching Weston(ivi-shell):

I executed the following lines:

    export QT_QPA_PLATFORM=wayland
    ./hello-qt-quick2

And I got:

    Using Wayland-EGL

But nothing happened in the screen.

I did it again with "WAYLAND_DEBUG=1". Here are the logs:
