Only look at the very first error and ignore the rest. There is a problem in 
line 37 or 38. Did you include <qobject.h>?

Sorry I did not reply to your initial mail.
You could also send the signal from DigikamView or DigikamApp, not sure 
currently which is an appropriate place. Probably most relevant classes 
already connect to some signals from AlbumManager, you might even be able 
reuse the slotAlbumIconChanged?
