[David Lichteblau (david-lichteblau)]

Can you compare the smoke.h from your kdebindings withh the one CommonQt HEAD is written for?

I'm on rev 1064293, which I thought was almost identical to KDE 4.4.x, but it might be better to check.

svn cat svn://anonsvn.kde.org/home/kde/trunk/KDE/kdebindings/smoke/smoke.h@1064293

I've also pushed more casting fixes, plus a missing slot in a struct definition. (Since you appear to be on a 64 bit system, the struct issue should have been hidden by 64 bit alignment though.)
