Debugger Gets Stuck When Trying to Debug Rust Inside a Dev Container

[mcmah309]

The debugger gets stuck when trying to debug rust container inside a dev container. Here's an example, it stays like this forever

2024-01-26.19-46-20.mp4

.devcontainer

{
	"name": "rust_dev",
	"image": "rust_dev",
	"customizations": {
		"vscode": {
			"extensions": [
				"rust-lang.rust-analyzer",
				"serayuzgur.crates",
				"vadimcn.vscode-lldb"
			]
		}
	},
	"mounts": [
		// rust
		"source=/home/henry/.local/share/containers/storage/volumes/rust_dev/_data/root/.cargo,target=/root/.cargo,type=bind",
		"source=/home/henry/.local/share/containers/storage/volumes/rust_dev/_data/root/.rustup,target=/root/.rustup,type=bind"
	],
	"runArgs": [
		"--net=host",
	],
	"remoteUser": "root"
}

Compiling with cargo and running with vscode works fine.

The output that is notable is this

Warning: codelldb.cargo tasks are unavailable in the current environment.

I was able to fix this issue by using another rust image. It would be nice if Warning: codelldb.cargo tasks are unavailable in the current environment. was more specific and didn't cause vscode to hang indefinitely without being able to be cancelled.

Same problem here. Docker image built from alpine:3.18 . Rust version 1.77.2 installed with rustup 1.27.0

[1414C]

Same issue:
MacOS Sonoma 14.2.1
rustup 1.27.0 (bbb9276d2 2024-03-08)
info: This is the version for the rustup toolchain manager, not the rustc compiler.
info: The currently active rustc version is rustc 1.77.2 (25ef9e3d8 2024-04-09)
rust-analyzer: v0.3.1932
CodeLLDB: v1.10.0

I have the same issue. Ubuntu 22.04.5 LTS. Installed rust, rust analyzer, and codelldb. Didn't work. Uninstalled every thing and reinstalled. Trying to run the simplest getting started program:

fn main() {
    let stdout = stdout();
    let out = b"Hello fellow Rustaceans!";
    let width = 24;

    let mut writer = BufWriter::new(stdout.lock());
    say(out, width, &mut writer).unwrap();
}

Same error, console output:

fn main() {
    let stdout = stdout();
    let out = b"Hello fellow Rustaceans!";
    let width = 24;

    let mut writer = BufWriter::new(stdout.lock());
    say(out, width, &mut writer).unwrap();
}

Warning: codelldb.cargo tasks are unavailable in the current environment.

I have no idea what error means or how to go about fixing it. Very frustrating when the very first simplest step doesn't work and no guidance to fix. I have googled extensively and can find almost nothing that addresses issue. Thank you for suggestions.

I don't know what is the reason behind, but It was fixed after I created new container (non-alpina)

Same getting stuck on rust:alpine3.21 docker, looks like it needs some additional software.
rust:latest, based on debian works ok.

I'm also having this issue, though occasionally if I wait a very long time ( >10 minutes ) it works? I was still getting the codelldb.cargo tasks are unavailable in the current environment message, though.

Curiously, I wasn't having this issue earlier today, but now I am after not having updated any packages on my system or any vscode extensions. Using lldb extension version 1.11.4, and I am not using it inside of a dev container.
