Problem with GDB and a Qt Quick application
I recently installed the whole QtSDK on my Debian stable with LXDE and created a test Qt Quick application, with a single QML file, using QtCreator IDE. When I try to run the application with the Run button (ctrl+r) inside QtCreator, everything goes well. The window is created and interface looks right.
But, if i try to debug the app with the "start debugging" button, the next 2 messages appears in the Application output, and app is finished:
&"warning: GDB: Failed to set controlling terminal: Invalid argument\n"
Qml debugging is enabled. Only use this in a safe environment!
can't find linker symbol for virtual table for `QmlApplicationViewer' value
pruebaQuick: cannot connect to X server
Debugging has finished@
I tried to deactivate access control on X Server using xhost -, but the result is the same, and I dont know how to solve it, or even the cause of the problem.
