c++ Anfänger b raucht hilfe

    Hallo


    Versuche gerade ein minimalistisches Frontend für xine in c++ zu entwerfen welches ich dann gerne in das vdr-xine-plugin hineinpatchen möchte...


    leider weiß ich nicht weiter (ist z.Z. zum testen stand alone)
    ich denke das ganze entsteht beim linken auf die xlibs


    es kommen immer folgende fehler

    Die Quellen habe ich mal angehangen damit der Thread nicht ewig lang wird.

    Hallo,


    Problem ist das Programm hat garkein main(), sondern nur XineFrontend::main. Dass das dem Compiler ned schmeckt ist klar :]. Und die unresolved symbols bei den statischen Klassenvariablen sind eigentlich auch leicht zu erklären: Keine der statischen Variablen ist im .c-File instantiiert worden.

    sorry


    war ein bissel dumme Frage ist schon alles behoben man sollte eben doch ein bissel besser im Buch nachlesen...


    Aber trotzdem danke nochmal
