Syntaxfehler beim Kompilieren

  • 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

    Dank& Gruß im Voraus

    Ausschnitt aus lib.c:

    #include "usb.h"
    #include <windows.h>
    #include <stdio.h>
    #include <string.h>
    #include "lib.h"

    usb_dev_handle *usbIODevice;// habe die Vermutung das der Fehler hier liegt!!

  • t mir leid!
    Habe das mit dem Source code wohl etwas zuuuuu gut gemeint! 🙄

    Fakt ist das ich eine dll erzeugen will zu Ansteuerung Eines USB Gerätes!
    Dazu verwende ich msvc6 und die Open Source Bib. Meine Vorkenntnisse was C++ an geht sind mittelmäßig... sagen wir mal so ich hasse Objekte!

    Über Hilfe würde ich mich seht freuen!

  • und wo tritt der Fehler auf?
