The issue you’re encountering seems to be related to the architecture mismatch between your development environment and the target environment. The warning Debuggee TargetArchitecture not detected, assuming x86_64 indicates that GDB is assuming the wrong architecture for your target.

Here are a few steps to troubleshoot and potentially resolve this issue:

  1. Ensure Arm Emulation is Enabled:
    Make sure that Arm emulation is properly enabled on your development machine. This is necessary to run Arm binaries on an x86 host. You can enable Arm emulation by running the following command:

    docker run --rm --privileged multiarch/qemu-user-static --reset -p yes

  2. Check Dockerfile Configuration:
    Verify that your Dockerfile is correctly set up to use the cross-compiled binary. Ensure that the binary is copied to the correct location and that the entry point or command in the Dockerfile points to the correct executable.

  3. Verify GDB Configuration:
    Ensure that GDB is correctly configured to recognize the target architecture. You might need to specify the architecture explicitly in your GDB configuration. You can do this by adding the following command in your GDB initialization file (.gdbinit):

    set architecture aarch64

  4. Use the Correct GDB for Arm:
    Make sure you are using the GDB that is configured for the Arm architecture. The message This GDB was configured as “aarch64-linux-gnu” suggests that you are using the correct GDB, but double-check to ensure there are no mix-ups.

  5. Debugging Configuration in VS Code:
    If you are using Visual Studio Code, ensure that your launch configuration (.vscode/launch.json) is correctly set up to use the Arm architecture. Here is an example configuration:

    {
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Torizon C/C++: GDB",
      "type": "cppdbg",
      "request": "launch",
      "program": "/path/to/your/executable",
      "args": [],
      "stopAtEntry": false,
      "cwd": "${workspaceFolder}",
      "environment": [],
      "externalConsole": false,
      "MIMode": "gdb",
      "miDebuggerPath": "/usr/bin/aarch64-linux-gnu-gdb",
      "setupCommands": [
        {
          "description": "Enable pretty-printing for gdb",
          "text": "-enable-pretty-printing",
          "ignoreFailures": true
        },
        {
          "description": "Set target architecture",
          "text": "set architecture aarch64",
          "ignoreFailures": true
        }
      ],
      "preLaunchTask": "build",
      "miDebuggerServerAddress": "localhost:1234",
      "targetArchitecture": "arm64",
      "pipeTransport": {
        "pipeCwd": "",
        "pipeProgram": "docker",
        "pipeArgs": [
          "exec",
          "-i",
          "your_container_name"
        ],
        "debuggerPath": "/usr/bin/aarch64-linux-gnu-gdb"
      },
      "sourceFileMap": {
        "/path/in/container": "${workspaceFolder}"
      }
    }
  ]
}

  6. Run the Container with Correct Settings:
    Ensure that when you manually run the Docker container, you are using the same settings as specified in your Dockerfile and VS Code configuration.

By following these steps, you should be able to resolve the architecture mismatch issue and successfully run and debug your cross-compiled binary within the Docker container. If the problem persists, please provide more details about your Dockerfile and VS Code configuration for further assistance.
