Reference error in winsock2

Question

I am wanting to create a socket in c with the windows api winsock2.h but while trying to compile my code returns me the following error

Undefined referrence to Wsastartup

Undefined referrence to Wsagetlast

Error error: Ld returned 1 Exit status

Winsock startup code

#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;
}

Answer 1

1) Remove this line of code

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

2) In Codeblocks IDE, enter a new project, I named it Sockets

3) Choose Console Application and click GO

In the window that appears click on Next and then choose the language C

4) In the main. c function put your code without using #pragma

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

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;
}

5) Right-click on the project name and choose Build Options

6) Choose (Click) the Linker Settings tab and Link Libraries click the ADD button

7) Type the following: ws2_32 and click OK

8) Compile and see that you are error free now

9) When executing appears the message in a good now! Bom Estudo!!! Note: If it is in another IDE see how to insert the blioteca because the GCC compiler often does not recognize or consider inclusions of bilbioteca via #pragma directive
