I’m brand new for C++, and I met the bug bother me for few days and desperatly for the answer:

I’m using macbook pro 2023 (Sonoma 14.5 M3 Max) and VS code. And here is my code:

main.cpp

#include<iostream>

void Log(const char* message);

int main()
{
    Log("Hello World");

    return 0;
}

Log.cpp

#include<iostream>

void Log(const char* message)
{
    std::cout<< message <<std::endl;

}

And

tasks.json

{
    "tasks": [
        {
            "type": "shell",
            "label": "shell: C/C++: g++ 生成活动文件",
            "command": "/usr/bin/g++",
            "args": [
               "-g",
                "${workspaceFolder}/*.cpp",
                "${fileDirname}/*.cpp",
                
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}"
            ],
            "options": {
                "cwd": "/usr/bin"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "调试器生成的任务。"
        }
    ],
    "version": "2.0.0"
}

And when I run it, the error shows:
enter image description here

I tried to type

g++ Log.cpp main.cpp

in terminal, and it works. I saw the a.out build successfully and I can use ./a.out to get Hello World! successfully.
I also copyed the code into Xcode (macos sonoma 14.5 M3max) and VS (windows). On both of them the code works.
I just don’t understand why I cannot make it work with changing tasks.json.

Thank you very much for answer and it will really help!

Best

I tried to modified the tasks.json with plenty of answer related but none of them works
