Mediapipe debugging in VScode

[zzmicer]

Is there any method/plugin to debug C++ mediapipe code in Visual Studio Code?

[sgowroji]

Hi @zzmicer, Could you please share whether you are not able to debug using this. And what is the error while trying with it. Thanks!

Hi @sgowroji, I try to debug Hand Tracking solution. I've already built it with bazel build -c dbg --define MEDIAPIPE_DISABLE_GPU=1 mediapipe/examples/desktop/hand_tracking:hand_tracking_cpu

This is my configuration for launch.json:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "LaunchDBG",
            "type": "cppdbg",
            "request": "launch",
            "program": "{my_path_to_mediapipe_repo}/bazel-out/k8-dbg/bin/mediapipe/examples/desktop/hand_tracking/hand_tracking_cpu",
            "args": [],
            "stopAtEntry": false,
            "cwd": "{my_path_to_mediapipe_repo}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}

When I launch debugging in VScode I get: &"warning: GDB: Failed to set controlling terminal: Operation not permitted\n" And then: E20210622 16:16:44.424080 13715 demo_run_graph_main.cc:154] Failed to run the graph: ; Can't find file: [1] + Done "/usr/bin/gdb" --interpreter=mi --tty=${DbgTerm} 0<"/tmp/Microsoft-MIEngine-In-umj2pouj.kvu" 1>"/tmp/Microsoft-MIEngine-Out-t565qo5v.ubg"

Also, I get this error window in VScode

[sgowroji]

Hi @zzmicer, After investigating the above with my team. We general use terminal or command prompt to build and run the code. We are not sure with your error. Thanks!

Hi, can you share the way you are debugging the code? even from cmd

[sgowroji]

Hi @chendadon, We don't recommend any as of now. but you can try doing with VScode from here https://docs.microsoft.com/en-us/visualstudio/debugger/quickstart-debug-with-cplusplus?view=vs-2019
