Hi,

I have a problem to compile my socket program.
I want to use winsock2.h, but when I compiled my program,
I got the following errors.

%gcc -lwsock32 -lws2_32 main.cpp
main.cpp: undefined reference to `WSASocketA AT 24'
main.cpp: undefined reference to `WSAIoctl AT 36'
main.cpp: undefined reference to `htons AT 4'
main.cpp: undefined reference to `bind AT 12'
main.cpp: undefined reference to `WSAIoctl AT 36'
main.cpp: undefined reference to `WSAStartup AT 8'
main.cpp: undefined reference to `WSACleanup AT 0'
main.cpp: undefined reference to `WSARecv AT 28'
main.cpp: undefined reference to `WSAGetLastError AT 0'
main.cpp: undefined reference to `WSARecv AT 28'
main.cpp: undefined reference to `WSAGetLastError AT 0'
collect2: ld returned 1 exit status

DLL version is  1.3.12.
I wrote program header as follows.

#define Win32_Winsock
#include <windows.h>
#include <winsock2.h>
#include <ctype.h>
#include <stdio.h>
#include <string.h>

I searched google and ML archive, but I couldn't get
enough information to solve this.
What can I do for this?
Please let me know.

Thanks,

Takeshi Honda
