Can't add "ws2_32.lib" in any way

Question

I'm beginning with socket programming in C++, and as a normal student, I went to search online.

The problem is, it doesn't matter what I do, I always get the following errors:

C:\Users\farin\AppData\Local\Temp\ccQCkFqw.o:main.cpp:(.text+0x37): undefined reference to `WSAStartup@8'
C:\Users\farin\AppData\Local\Temp\ccQCkFqw.o:main.cpp:(.text+0x48): undefined reference to `WSAGetLastError@0'
collect2.exe: error: ld returned 1 exit status

I'm using MinGW in Visual Studio Code.

Here's the sample code I've been messing around with:

/*
    Initialise Winsock
*/

#include<stdio.h>
#include<winsock2.h>

#pragma comment(lib,"ws2_32.lib") //Winsock Library

int main(int argc , char *argv[])
{
    WSADATA wsa;
    
    printf("\nInitialising Winsock...");
    if (WSAStartup(MAKEWORD(2,2),&wsa) != 0)
    {
        printf("Failed. Error Code : %d",WSAGetLastError());
        return 1;
    }
    
    printf("Initialised.");

    return 0;
}

I've already tried linking to the compiler, and possibly gone throught all the pages about the subject that I could find.

Have you tried linking it on the command line? I don't know if MinGW works with that pragma as the Microsoft compiler does. — Retired Ninja, Sep 23 '22 at 02:29

`g++ -Iws2_32.lib main.cpp -o main.exe` and without the .lib — Rodriggrr, Sep 23 '22 at 02:35
Libraries need to come after the code that uses them on the command line. Move `-lws2_32` to the end of the command line. Note there's no extension. — Retired Ninja, Sep 23 '22 at 02:37

Solution is here!

Just ran throught the command line, as follow:

g++  main.cpp -o main.exe -lws2_32

Thanks to Retired Ninja.
