Hi all,

I am able to run a qt GUI application with Qt Creator in a Host System on a Beaglebone revC target. I can run the application using the Run Green Button on the left side.

But the same application, when I debug, it is showing the following error in the target terminal.

No protocol specified
QXcbConnection: Could not connect to display :0.0

Child terminated with signal = 0x6 (SIGABRT)
GDBserver exiting

For Remote Debugging, I am following the guide - http://doc.qt.io/qtcreator/creator-debugger-operating-modes.html.

In my target system Beaglebone black, I have already run sudo apt-get install gdb-multiarch and put the gdbserver in /home/debian directory.

From /home/debian in target system, I am running the command ./gdbserver :5555 LTC_Qt_App_Ver_0_02.

Then I use Debug->Start Debugging->Attach to Running Debug Server... in Qt Creator in Host System.

Debugging is getting started. My main() is as follows.

QApplication a(argc, argv);
HomeMenu w;
w.show();
return a.exec();

When I put a breakpoint at Homemenu w ;
and proceed the above mentioned error appears in target terminal.

Thanks in advance for the help in solving this problem.

Thanks & Regards,
