Hallo erstmal,
Habe da einen völlig nervigen Fehler vielleicht kann mir ja jemand helfen:
error C2143: Syntaxfehler : Fehlendes '{' vor 'PCH creation point'
Bei dem Ganzen Spaß soll nachher eine dll Datei zur Ansteuerung eines USB Gerätes heraus kommen. Als Hilfe benutze ich die libusb-win32 von sourceforge.net.
Dank& Gruß im Voraus
Philipp
