qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
-
Hello,
I'am just installing Qt Creator on Debian 10. Th installation is successful but when I double click on the shortcut desktop nothing is happening.
I try to launch the software with a terminal and I have this result :aurelien@debian:~$ /home/aurelien/Qt/Tools/QtCreator/bin/qtcreator qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found. 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. AbandonI'have read about this on forum but nothing works.
Can yo tell me how can I fix this issue please ?
Regards

Hi and welcome to devnet,
Start again your application with the QT_DEBUG_PLUGINS environment variable set to 1.
You'll have information about what is happening with the plugins.

Hi @SGaist ,
When I do :QT_DEBUG_PLUGINS=1then it's the same result :
/home/aurelien/Qt/Tools/QtCreator/bin/qtcreator qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found. 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. AbandonPerhaps it's not the good process to change the QT_DEBUG_PLUGINS environment variable. Sorry, i'm a beginner informatic student :)

How did you do that exactly ?

As I said, I did :
aurelien@debian:~$ QT_DEBUG_PLUGINS=1 aurelien@debian:~$ /home/aurelien/Qt/Tools/QtCreator/bin/qtcreator qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found. 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. Abandon -

Beside what @Pablo-J-Rogina suggested, you can also run ldd against the xcb plugin that you'll find under the QtCreator folder to see if you are missing something.
