+# Native Image Debugging from Java Source Code
+
+This demo is intended to demonstrate how to debug a Java application, built into a native executable, using the [Debug Info Feature in Native Image](https://www.graalvm.org/latest/reference-manual/native-image/debugging-and-diagnostics/DebugInfo/).
+
+> Prerequisites: Linux OS with 10.2 or later
+
+## Build a Native Executable with Debug Information
+
+1. Clone Download or clone the GraalVM Demos repository:
+    ```bash
+    git clone https://github.com/graalvm/graalvm-demos
+    ```
+
+2. Navigate to the example directory:
+    ```bash
+    cd graalvm-demos/archive/javagdbnative
+    ```
+
+3. Compile and build the application with Maven:
+    ```shell
+    mvn -Pnative -DskipTests package
+    ```
+    The command packages a Java application into a runnable JAR file, and then builds a native executable of it.
+    The `-g` option that is passed to the `native-image` tool in _pom.xml_ causes debug information to be generated.
+    Next to the native executable, you see the _<executable_name>.debug_ file that contains debug information, and the _sources_ directory containing Java source files, which the debugger uses to show sources for line information.
+
+Now you can debug your native executable with GDB as shown in [this guide](https://www.graalvm.org/latest/reference-manual/native-image/guides/debug-native-image-process/).
