Bonjour,
J'éssaye de travailler avec les winsocks mais à chaque fois que je compile, j'ai ce message d'erreur :

je suis sous code::blocks.

quelqun a une idée ?
merci d'avance

Il manque la library winsock.

Pour vc ca donne: #pragma comment(lib, "ws2_32.lib")

Il faut inclure winsock2.h et linker avec la bibliothèque libws2_32.a

Salut :

si tu travailles avec VC++ :
#include <winsock2.h>
#pragma comment (lib , "WS2_32.lib")


si tu travaille avec Dev-Cpp :
#include <winsock2.h>
Project > Project Options > Parameters > Linker
Ajouter libws2_32.a

Merci
