  #pragma comment(lib,"Ws2_32.lib")
#include <winsock2.h>
#include <iostream>
#define REMOTE_ADDR 37.18.153.219

using namespace std;

int main()
{
    int error;
    WSADATA ws;
    if (FAILED( WSAStartup(MAKEWORD(1, 1), &ws))) {
        error = WSAGetLastError();
    }
    SOCKET s;
    if (INVALID_SOCKET == (s = socket (AF_INET, SOCK_STREAM, 0))) {
        error = WSAGetLastError();
    }

//    sockaddr_in s_addr;
//    ZeroMemory(&s_addr, sizeof(s_addr));
//    s_addr.sin_family = AF_INET;

//    s_addr.sin_addr.S_un.S_addr = inet_addr(REMOTE_ADDR);
//    s_addr.sin_port = htons(80);

//    if (SOCKET_ERROR = (connect(s, (sockaddr*) &s_addr, sizeof(s_addr)))) {
//        error = WSAGetLastError();
//    }
}


How can I fix this compiling error?

INCLUDEPATH += "C:\Program Files\Microsoft SDKs\Windows\v6.0A\Lib\x64"
LIBS+="WS2_32.Lib"

 
 
LIBS+="C:\Program Files\Microsoft SDKs\Windows\v6.0A\Lib\x64\WS2_32.Lib"

The same error appears.
