VSCode LLDB on MacOS error when starting debugging session - c++

Question

I'm trying to configure VSCode for compiling/debugging C++ programs on MacOS. I am using the following launch.json file:
When I try and start a debugging session, I get the following error:
Warning: Debuggee TargetArchitecture not detected, assuming x86_64.
ERROR: Unable to start debugging. Unexpected LLDB output from command "-exec-run". process
exited with status -1 (attach failed ((os/kern) invalid argument))
The program '/path/to/Development/C++/helloworld/main' has exited with code 42
(0x0000002a).
It is worth mentioning that I am using an M1 Macbook, so x86_64 is not the correct architecture. I'm assuming that this is the reason for the error.
I can't seem to find any reference to this error anywhere online, does anyone know how I can solve this?
Edit: Adding "targetArchitecture": "ARM64" removed the warning, but does not fix the error.

Answer 1

I had the same problem and I found that VScode does not support a debugger for ARM64 binaries yet. Here is the issue link.
However, it works if you use another extension. Install CodeLLDB and set "type": "lldb" on launch.json like below.
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"name": "clang++ - Build and debug active file",
"type": "lldb",
"request": "launch",
"program": "${fileDirname}/${fileBasenameNoExtension}",
"args": [],
"cwd": "${workspaceFolder}",
"preLaunchTask": "clang++ build active file"
}
]
}
You can check quick start guide of vscode-lldb repository.
Note that preLaunchTask's value should be the same as the label's value in your task.json.

Answer 2

Make Executable with command:
gcc file_name.c -g
launch.json
"targetArchitecture": "x86_64",

Answer 3

Using cargo's config instead of "program" resolved it for me (using Rust and LLDB).
{
"name": "(OSX) Launch",
"type": "lldb",
"request": "launch",
"cargo": {
"args": ["build", "--manifest-path", "${fileDirname}/../Cargo.toml"]
}
}
