schreibe mir gerade eine Klasse, die in einem seperaten QThread laufen soll und alle ICMP-Nachrichten abfängt, auswertet und dementsprechend Signale an anderen QObjecten senden soll.
Nun aber das Problem: Wenn man die <winsock2.h> includiert, wieso kann man dann nicht auf dessen Funktionen zugreifen? z. B. WSAStartup(), sendto(), recfrom() etc... -halt alles was in der winsock2.h deklariert ist.
Compilieren lässt sich das Programm, erst beim Linken kommen die Fehlermeldungen. siehe:
Die Klasse funktioniert bereits, aber nur als DOS-Programm. Muss es halt in eine QT-Klasse portieren...G:\scan\v4>make
