    Hi,

    ich habe noch nicht viel mit c++ gearbeitet und versuche gerade ein Programm zu compilieren, was aber leider nicht funktioniert. Ich arbeite mit einem Mac.
    Hier erstmal die Fehlermeldung:

    Ich hab schon ein bisschen das Internet durchgeforstet und gemerkt, dass die Funktionen vllt. nicht initialisiert sind oder es irgendwas mit den Libraries zu tun hat, da kenn ich mich aber nicht so aus.

    Du hast scheinbar vergessen eine benötigte Lib mitzulinken. Welche das ist siehst du an Hand der Ausgabe (ich erkenne jetzt nicht hundertprozentig woher die Klassen stammen könnten, aber ich tipp mal auf wxwidgets). Und wie du die dazulinkst entnimmst du am Besten der Doku deines Compilers/Linkers.

    Danke erstmal für die schnelle Antwort!
    okay, ähm, ich kompiliere das Ganze über das Makefile auf der Kommandozeile, wie kann da denn jetzt die Doku sehen? Und wxWidgets ist richtig.

    Die Doku deines Compilers findes du im Netz. Du musst vermutlich einfach nur das Makefile anpassen. Nach der Fehlermeldung zu googlen hilft auch häufig weiter - du bist vermutlich nicht der erste mit der Fehlermeldung 😉

    Ja, Du compilierst alle Quelldateien, linkst dann aber nur die GUI.o zu einem Programm zusammen - da fehlen die ganzen Objekte.

    ok, ich schätze mal du meintest, das es so aussehen sollte(natürlich ohne den Fehler):

    Das doofe ist jetzt, dass er Probleme mit wxGLCanvas hat. Das gehört aber auch zu wxWidgets und da hab ich ja eigentlich die libraries...

    hier nochmal wxGLCanvas2.cc falls das irgendwie hilft...

    #include "wxGLCanvas2.h"

BEGIN_EVENT_TABLE(wxGLCanvas2, wxGLCanvas)
  EVT_PAINT(wxGLCanvas2::OnPaint)
  //EVT_ERASE_BACKGROUND(wxGLCanvas2::OnEraseBackground)
END_EVENT_TABLE()

wxGLCanvas2::wxGLCanvas2(wxWindow * parent, wxGLCanvas2_Render * render)
  : wxGLCanvas(parent,-1), m_render(render)
{

}

void wxGLCanvas2::OnPaint(wxPaintEvent & e)
{
  wxPaintDC dc(this);
//  cout << "wxGLCanvas2::OnPaint" << endl;
  SetCurrent();
  m_render->render();
  SwapBuffers();
}

    Sorry, dass ich mich schwierig anstelle...
