With the proviso that I have no KDE experience...

Oops...your mailer performed "line wrapping" on your ld output!!
I have pseudo-"unwrapped" the lines in my reply, for the sake of
argument^Willustration ;) I might not have done it right, though.

I haven't encountered this recently (or at all?) so I have to
guess. You know what, at first glance I would say "where are the other
lines"? I don't recognise the ':' followed by ':' motif, no why 'first
defined here' doesn't have something more well-phrased appearing after
it? Did you upgrade compiler / KDE in the middle of your development?
Could this be due to some inability of the compiler to resolve names
properly?

Have you got any diagnostic messages to go with that? One possible
explanation is that you have old linked libraries in your development
tree. It only takes on of them to have a reference to the old libraries
and you will have trouble. Can you `make clean` to delete the old
object files and recompile everything from scratch?
