The Qt Creator debugger plugin acts as an interface between the Qt Creator core and external native debuggers such as the GNU Symbolic Debugger (GDB), the Microsoft Console Debugger (CDB), a QML/JavaScript debugger, and the debugger of the low level virtual machine (LLVM) project, LLDB.

The debugger plugin automatically selects a suitable native debugger for each kit from the ones found on your system. To override this choice, select Tools > Options > Build & Run > Kits.

To add debuggers:

1. Select Tools > Options > Build & Run > Debuggers > Add.
2. In the Name field, give a descriptive name for the debugger.
3. In the Path field, specify the path to the debugger binary:
   • For CDB (Windows only), specify the path to the Windows Console Debugger executable.
   • For GDB, specify the path to the GDB executable. The executable must be built with Python scripting support enabled. The options you have depend on the development and target platform:
     • For debugging on embedded devices using a different ABI, you must provide a special executable.
     • For debugging on Windows using MinGW, select a Windows executable of GDB with Python scripting enabled. You can download it from http://builds.qt-project.org/job/gdb-windows.
   • For LLDB (experimental), specify the path to the LLDB executable.
4. In the ABIs field, specify the ABI versions to use on embedded devices.
