Visual C++ 6 : error LNK2001: unresolved external symbol

Question

Lorsque je link ce server TCP/IP avec Visual C++ 6.0 j'ai les erreurs de link suivante : --------------------Configuration: all - Win32 Debug-------------------- Linking... all.obj : error LNK2001: unresolved external symbol [mailto:_recvfrom@24 _recvfrom@24] all.obj : error LNK2001: unresolved external symbol [mailto:_sendto@24 _sendto@24] all.obj : error LNK2001: unresolved external symbol [mailto:_inet_addr@4 _inet_addr@4] all.obj : error LNK2001: unresolved external symbol [mailto:_htons@4 _htons@4] all.obj : error LNK2001: unresolved external symbol [mailto:_WSAGetLastError@0 _WSAGetLastError@0] all.obj : error LNK2001: unresolved external symbol [mailto:_socket@12 _socket@12] all.obj : error LNK2001: unresolved external symbol [mailto:_WSAStartup@8 _WSAStartup@8] Debug/all.exe : fatal error LNK1120: 7 unresolved externals Error executing link.exe. all.exe - 8 error(s), 0 warning(s) j'ai pourtant ajouté les librairies wsock32.lib et ws2_32.lib pour le link...
