Problem ablout jetson nano Qt -creator debug

I installed Qt with: (Sudo Apt-get Install QT5-Default QtCreator -y) in Jetson Nano and set up the following project。
The following is the file of :
//======== This is automatically configured for new projects
QT -= gui
CONFIG += c++11 console
CONFIG -= app_bundle
SOURCES += main.cpp

The following is the file of qt_demo.main.cpp:
#include <QCoreApplication>
#include <QtDebug>
int main(int argc, char **argv)
QCoreApplication a(argc, argv);
int c = 10;
qDebug() << c;
return a.exec();

And then I can run by ctrl+rI can press CTRL + R to work properly
But I couldn’t debug and got the following error

and I’m using the GDB debugger, as shown below

Thank you very much for your help

Qt is 3rdparty software implementation and we don’t have much experience on it. What we have tried is to build and install it. The steps are shared in

We don’t have experience on using the debug tool. May need other users to give suggestion.

Thanks for your reply. I recently solved this problem by replacing the QT debugger with an LDB debugger. I wish you every success in your work.
