Debuggee: compiled rust program that needs to run as sudo in the debug session

I am able to debug my target rust app in VS code using CodeLLDB when the target app runs non-privileged. However, I need to debug the target process running as sudo (as it is a requirement). Is there any way to do this using this extension?

Currently the only way to do that is via remote debugging, i.e. launch lldb-server as root, connect to it from codelldb, etc.

how do you connect to it?

@Mart-Bogdan See https://github.com/vadimcn/codelldb/blob/v1.10.0/MANUAL.md#remote-debugging

Thanks. I've managed to do remote debug back then.
Not perfect experience, but it worked!

Hi all, could I have some pointers on how to do this properly? I'm trying to set this up to enable elevated debugging of a Rust program but I'm finding an error I don't quite get.

I have set up this launch config:

    {
      "type": "lldb",
      "request": "launch",
      "name": "Remote Debug executable '<BINARY_NAME>'",
      "program": "${workspaceFolder}/target/debug/<BINARY_NAME>",
      "initCommands": [
        "platform select remote-linux",
        "platform connect connect://localhost:23809",
      ],
    },

I run sudo lldb-server platform --server --listen *:23809 and when trying to stat debugging this happens.

The text output from LLDB doesn't offer any additional info:

[ERROR codelldb::debug_session] Is a directory
Debug adapter exit code=0 (0x0), signal=null.

The path I'm setting in program is confirmed to be pointing to the binary itself, so not sure where this Is a directory is coming from.
