or am I doing something wrong?

same here, i added $(LIB_KIO) to no effect.

I don't get this error with smoke, but I do get the following link error with
korundum:

However I'm unsure this is the correct way to export a class defined in a .ui.
The qt docs suggest this method, but no other KDE .ui that I've seen does this.

I guess the real question is should this symbol be exported?

If so, then this patch needs to go into kdelibs.

If not, then we need to remote knotifywidgetbase.h from kdebindings/smoke/kde_header_list

It's been removed from the java bindings, so I think the best thing to do is 
remove it from the kde_header_list as you suggest.
