Backtrace of one such crash.
Backtrace with debug symbols for Qt |
||
Unfortuntely the debug symbols for Qt are missing and it crashes directly when creating the QApplication. Given the information we have from it: do you have the KWin QPA plugin installed to the correct location so that Qt finds it? (In reply to Martin Gräßlin from comment #1) > Given the information we have from it: do > you have the KWin QPA plugin installed to the correct location so that Qt > finds it? How can I check if I have it? I'm not sure if this is related, but when I type 'kwin_wayland --version', I get the following output: kwin_wayland --version This application failed to start because it could not find or load the Qt platform plugin "wayland-org.kde.kwin.qpa" in "". Available platform plugins are: wayland-org.kde.kwin.qpa, eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb. Reinstalling the application may fix this problem. fish: “kwin_wayland --version” terminated by signal SIGABRT (Abort) However, typing 'kwin_x11 --version' gives just the application name and version number as expected. On further digging, I found that this happens when I'm using qt 5.9 beta 3. Using qt 5.8, the wayland session launches normally. Created attachment 105334 [details]
Backtrace with debug symbols for Qt
I have attached a backtrace generated after installing qt with debug symbols.
Changing to invalid as KWin must be run against the Qt version it was compiled with. |
