Remote debugging: No such file or directory #963

Closed tgeorg-ethz closed 1 year ago

OS: Ubuntu 20.04.5 LTS VSCode version: 1.79.2 CodeLLDB version: v1.9.2 Compiler: Rust Debuggee: aarch64-linux-gnu

I'm currently trying to debug an application that is supposed run as root. As vscode run from user mode (to my knowledge) does not offer a way to attach to a binary run as root, I'm doing this by spawning an lldb-server as root (sudo lldb-server platform --server --listen localhost:7777) and then attaching to that server.

So to recap I'm trying to attach to an lldb-server running on the same machine

I'm using the following config based on the one described here

        {
            "name": "Remote launch",
            "request": "launch",
            "type": "lldb",
            "program": "${workspaceFolder}/10f10m_sync/syncN/timely-on-fpga/target/debug/examples/hello_fpga", // Local path.
            "initCommands": [
                "platform select remote-linux",
                "platform connect connect://localhost:7777",
            ],
        }

However when launching the debug session in vscode I get

Unfortunately I get no information what the file is that wasn't found. I'm certain that the path to the binary is correct as changing that gives me an entirely different error telling me that the binary wasn't found.

Attaching to the lldb-server via lldb from the command line does work just fine:
