I'm using Wayland session on Debian 11 (sid). Installed QtCreator from their website via .sh script but it doesn't launch. When running from '~/Qt/Tools/QtCreator/bin' directory in the terminal I get:
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway. qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in "" This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.
Aborted
Tried
QT_QPA_PLATFORM=wayland ./qtcreator
and
export QT_QPA_PLATFORM=wayland
./qtcreator
and
./qtcreator --platform=wayland
Also tried installing qt 6.0.3 and 5.15.
No luck, qtcreator doesn't launch.
