What is causing this compilation error with g++?

Question

I am trying to use asio library for networking in c++ but I have failed to load it. I am using visual studio code, mingw/g++ This is the path to my include folder -> C:\msys64\mingw64\include Here is the code in my main file.

#include <iostream>
#include <asio.hpp>
#include <asio/ts/buffer.hpp>
#include <asio/ts/internet.hpp>

int main()
{
    return 0;
}

This is the result of compilation

C:\Users\2022\Desktop\TUTORIALS\C++\SocketsTutorial>g++ main.cpp -o main.exe -I C:\Users\2022\Downloads\asio-1.24.0\asio-1.24.0\include

Thank you in advance :)

You should add compilation command that generates the error. Also you can check [this answer](https://stackoverflow.com/a/12472772/12463055) for solution of similar question. — erenalyoruk, Nov 06 '22 at 11:22
This is the command -> g++ main.cpp -o main.exe -I C:\Users\2022\Downloads\asio-1.24.0\asio-1.24.0\include — jamie_0101, Nov 06 '22 at 11:25
You should add library called `ws2_32` for Windows socket. The final command should be `g++ main.cpp -o main.exe -I C:\Users\2022\Downloads\asio-1.24.0\asio-1.24.0\include -lws2_32`. I have never used that asio library but it should be work. — erenalyoruk, Nov 06 '22 at 11:35
