C++ not executing on M1 Mac VS Code

Question

Code able to compile, but not executing, i.e. output not showing in debug window, breakpoints are not hit. Same configuration was working on non M1 Mac

Task.json:

{
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "2.0.0",
"tasks": [
  {
    "type": "shell",
    "label": "clang++ build active file",
    "command": "/usr/bin/clang++",
    "args": [
      "-std=c++17",
      "-stdlib=libc++",
      "-g",
      "${file}",
      "-o",
      "${fileDirname}/${fileBasenameNoExtension}"
    ],
    "options": {
      "cwd": "${workspaceFolder}"
    },
    "problemMatcher": ["$gcc"],
    "group": {
      "kind": "build",
      "isDefault": true
    }
  }
]
}

launch.json:

        "MIMode": "lldb",
        "preLaunchTask": "C/C++: clang++ build active file"
    }
]
}

cp_properties.json

{
"configurations": [
  {
    "name": "Mac",
    "includePath": ["${workspaceFolder}/**"],
    "defines": [],
    "macFrameworkPath": [
      "/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks"
    ],

    "cStandard": "c11",
    "cppStandard": "c++17",
    "intelliSenseMode": "clang-x64"
  }
],
"version": 4
}

Terminal Output:

Starting build...
/usr/bin/clang++ -fdiagnostics-color=always -g 
/Users/gyan/workplace/vscode/test/test.cpp -o /Users/gyan/workplace/vscode/test/test
Build finished successfully.

Terminal will be reused by tasks, press any key to close it.

test.cpp:

#include <iostream>
#include <sstream>

using namespace std;

int main(){
   string s = "my     name  is      Gyan p\n";
   istringstream iss(s);

   string word;
   cout<<"s";

   while(iss >> word){
       cout<<word<<" ";
   }

   return 0;
}

Not getting any idea of the issue

Answer 1

I fixed it using following config changes in launch.json:

"-arch", "x86_64",


"targetArchitecture": "x86_64",
"osx": {
                "preLaunchTask": "C/C++: g++ build active file",
                "MIMode": "lldb"
            }
