Debug Qt applications

To debug an application:

1. Go to Run and Debug (Ctrl+Shift+V or Cmd+Shift+V on macOS).

   

2. Create a launch.json file (1) that contains launch configurations. For more information, see VS Code: Debugging in the VS Code documentation.
3. Select Add Configuration (2), and then select a Qt: Debug debug configuration that matches your debugger.
4. Check the launch target (3). To change it, select the target name or go to Command Palette and select CMake: Set Launch/Debug Target.

Select one of the following Qt debug configurations:

• Qt: Debug with cppdbg for debugging C/C++ applications with GDB.
• Qt: Debug with cppvsdbg for debugging C/C++ applications with the Visual Studio Windows debugger.
• Qt: Debug with lldb for debugging with LLDB.
• Qt: Debug Qt WASM with Chrome for debugging Qt WebAssembly applications with Chrome.
