This application failed to start because it could not find or load the Qt platform plugin "xcb".

[Michael_liu]

I create a PC application on ubuntu14.04(64bit), this application is statically compiled with Qt-5.5.1 , and I have installed Qt Creator5.5 on my PC.
At last, I run application, but it gives me an error:

*This application failed to start because it could not find or load the Qt platform plugin "xcb".

Reinstalling the application may fix this problem.*

I don't know why, somebody could help me ?

Hi
If you are using static linking it sounds like you have a license for Qt
and you could call support directly and get pro help.

That said, you should try to ldd the "exe" and see what it says.
If static linked, it should not need plugins as far as I know.
