fehlermeldung

[cpeterpan]

hallo
ich versuche mein programm zu compilieren mit c++, so heisst der compiler(!), ich bekomme folgende fehlermeldung:

window2.o: In function window2::window2(int)': /srv/home/ea/work2/window2.cc:80: undefined reference towindow2::SigC::ObjectScoped virtual table'
/srv/home/ea/work2/window2.cc:80: undefined reference to window2 virtual table' window2.o: In functionwindow2::~window2(void)':
/srv/home/ea/work2/window2.cc:144: undefined reference to window2 virtual table' /srv/home/ea/work2/window2.cc:144: undefined reference towindow2::SigC::ObjectScoped virtual table'
collect2: ld returned 1 exit status
make: *** [camcalb] Error 1

ich glaube, das programm stimmt, aber trotzdem kommt das da, woran könnte es liegen?

das ist die klasse:

#include "camdata.hh"
#include "window2.hh"
#include "window1.hh"

gint delete_event_impl(GdkEventAny*)
{
    Gtk::Main::quit();
    return 0;
}

hi

eine sache habe ich dazu gefunden, weils mich interessiert hat, kann ja sein, daß es weiterhilft...:

frage hier:
[sigc] undefined reference to `Sim::SigC::ObjectScoped virtual table'
http://www.geocrawler.com/archives/3/3727/2001/1/0/5017329/

antwort dort:

This sounds a bit like a problem with where the vtable got
put. On some versions of gcc I have noticed that if you do
not declare and define the dtor of a class which uses sigc++
it returns such an error.

Try adding a dtor to your class (both the signal user and
the signal receiver) and see if that clears things up.
The dtor should not be inline. It must appear in a .cc
file so that the compiler knows which object file to
place the vtable.

Hope it helps.
