4. Textur laden läuft nicht

Textur laden läuft nicht

    Moin,
    ich habe versucht den Code von Nehe in mein Programm zu bekommen. Nur bekomme ich beim Linken immer folgende Meldung:

    main.obj : error LNK2001: Nicht aufgelöstes externes Symbol "_auxDIBImageLoadA@4".
    fatal error LNK1120: 1 nicht aufgelöste externe Verweise.

    die glaux.lib ist eingebunden. (Habe ich bei google gefunden, dass das ein Fehlergrund sein könnte).

    Ich wüsste sonst nicht was es sein könnte.
