    Hello,

    I have created simple widget based GUI application. I have don no special settings in project. But can't start debug it:

    Debugging starts
Debugging has failed
Debugging has finished

    How to fix that?

    Hi @column

    We need some more information to help you.

    • Which platform are you working on?
    • Which Qt and QtCreator version are you using?
    • Which compiler (GCC, MSVC, MinGW, Clang)?

    Also, to fix debugger problems it's often best to post QtCreators debugger log: Window > Views > Debugger Log. The right side of this log should be sufficient.

    Regards

    Qt has to stay free or it will die.

    @column:

    dUNSUPPORTED GDB VERSION GNU gdb (GDB) Red Hat Enterprise Linux (7.2-92.el6)

    This version of GDB is really old. Can you try updating it?

    Edit: and Creator 3.5.1 is stone-old too...
