# Debugging in DevEco Studio


DevEco Studio provides a wide range of debugging features, which can be used to detect and rectify program errors during NDK development. These debugging features include:


- Debugging using a real device: Run your application or atomic service on a real device to see how it behaves on the device. For details, see <!--RP1-->[Debugging Overview](https://developer.huawei.com/consumer/en/doc/harmonyos-guides-V5/ide-debug-device-V5)<!--RP1End-->.
  During debugging, if the source code path of the .so file of the local compilation device is different from the configured C++ source code path, fix the issue using either of the following methods:

  - Create the mapping between files.<br>After you debug code with the Step Into feature, you will be prompted to associate the source code. Click **Select file** and select the local C++ source code for association. For details, see <!--RP2-->[Third-Party Code Debugging](https://developer.huawei.com/consumer/en/doc/harmonyos-guides-V5/ide-source-code-debugging-V5)<!--RP2End-->.

  - Create the mapping between paths.<br>Choose **Run** > **Edit Configurations**, select a module, switch to the **Debugger** tab, select **Native**, and add the **settings set target.source-map "/buildbot/path" "/my/path"** command on the **LLDB Startup Commands** tab page to establish the mapping. Parameter 1 indicates the source code path in the compilation environment, and parameter 2 indicates the local source code path.

- C/C++ reverse debugging: During debugging, you can roll back to historical lines and breakpoints to view related variable information. For details, see <!--RP3-->[Reverse Debugging](https://developer.huawei.com/consumer/en/doc/harmonyos-guides-V5/ide-debug-native-reverse-V5)<!--RP3End-->.
