Debugging

Qt Creator provides a debugger plugin that 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), and a QML/JavaScript debugger.

The following sections describe debugging with Qt Creator:

• Debugging the Example Application uses an example application to illustrate how to debug Qt C++ applications in the Debug mode.
• Launching the Debugger describes the operating modes in which the debugger plugin runs, depending on where and how the process is started and run.
• Interacting with the Debugger describes the views and functions available in the Debug mode.
• Setting Up Debugger summarizes the support for debugging C++ code and requirements for installation. Typically, the interaction between Qt Creator and the native debugger is set up automatically and you do not need to do anything.
• Using Debugging Helpers describes how to get more detailed data on complex data.
• Debugging Qt Quick Projects describes how to debug Qt Quick projects.
• Detecting Memory Leaks describes how to use the Valgrind Memcheck tool to detect problems in memory management.
• Troubleshooting Debugger lists some typical problems that you might encounter while debugging and solutions to them.
