[Boost-users] linking to boost signal library

I'm trying to incorporate BOOST signals into my vc8 project.
I have built the dynamic libraries with the installer and set the 
project dependencies accordingly.
I have written the simplest signal test code possible.
The project compiles, but when linking I get the following error:

What could I be doing wrong?
