linking problems

[Michael Olbrich]

Hi!

I'm writing a prgram with kdevelop. I started with a "KDE 2 nomal" project
but it's KDE3/QT3 now.

It was all ok until I did this:

class BasicListView : public KListView
{
Q_OBJECT
[...]
}

class RegionListView : public BasicListView
{
Q_OBJECT
[...]
}


then I get undefined references to all functions of BasicListView.
This only happes if the first class (BasicListView) is in some way derived
from QObject. What's going on here? What is kdevelop doing wrong here, or
did I miss something?
