OS: 5.19.0-46-generic VSCode version: Version: 1.80.0 CodeLLDB version: v1.9.2 Compiler: rustc 1.49.0-nightly (e160e5cb8 2020-10-14) Debuggee: Rust file

Reference: https://zenodo.org/record/7871547 I try to debug and create breakpoints for this command.

cargo run --release --bin unsafe-counter --  /root/lab/laertes/rewrite-workspace/bzip2/rust/c2rust-lib.rs

I can execute this function successfully and able to debugging and create breakpoints in CLion + IntelliJ Rust Plugin. But errors occur in Vscode with CodeLLDB

You are not supposed to run the binary with cargo, just to build it.

sorry for missing leading, the debuggee is actually a Rust file under --bin folder, NOT binary file. I have edited the issue.

I didn't create the command on my own, it's actually the code and commands from Top Software Engineering Research Conference 2021 ACM on Programming Languages OOPLSA accepted article: Translating C to safer Rust

Your launch config should be something like this:

{
    "version": "0.2.0",
    "configurations": [
      {
        "sourceLanguages": ["rust"],
        "type": "lldb",
        "request": "launch",
        "name": "Launch unsafe-counter",
        "cargo": {
          "args": [ "build", "--bin", "unsafe-counter"],
          "filter": {
            "name": "unsafe-counter",
            "kind": "bin"
          }
        },
        "args": ["/root/lab/laertes/rewrite-workspace/bzip2/rust/c2rust-lib.rs"],
        "cwd": "/root/lab/unsafe-counter"
      }
    ]
}
