Cannot deploy app :This application failed to start because it could not find or load the Qt platform plugin "xcb".
-
I want to deploy my application on a system which doesn't have Qt installed. I have copied all the dependencies. But when I start my app I get an error.
This application failed to start because it could not find or load the Qt platform plugin "xcb".
Available platform plugins are: xcb (from ./SCoMoS), xcb.
Reinstalling the application may fix this problem.

Hi,
Did you follow the "Linux deployment guide":http://qt-project.org/doc/qt-5/linux-deployment.html#creating-the-application-package ?
-
no. I dint follow
-
I am able to open the app now but I cannot connect to DB getting QMYSQL driver not loaded error
-
Did you deploy the MYSQL plugin?
See the diagram "here":http://qt-project.org/wiki/Deploy_an_Application_on_Windows. Add "sqldrivers/qsqlmysql.so" instead of "imageformats/qjpeg.dll".
