bonjour,
donc voila g un gros probleme avec les socket. dès que je compile un code avec un socket, le linker me dit des truc et n'execute pas le prog. je vais vous donner le code source:
#include <iostream>
using namespace std ;
#include <stdlib.h>
#include <winsock.h>
#include <string.h>
#define PORT 15 // Port arbitraire de communication
//#define DEBUG // Si vous voulez pouvoir afficher les codes d'erreur
void ErreurWSA();
void main()

s = socket(AF_INET,SOCK_STREAM,0);

ErreurWSA();

exit(1) ;
}
else

voila je le compile et il y a une fenetre qui me met :
-undefined reference to "WSAstartup@8"
- undefined reference to "socket@12"
- undefined reference to htons@4"
-undefined reference to "bind@12"
et il continue avec toute les autres fonction socket.
que dois-je faire??
SVP aidez-moi
