Dissolve plugin example won't build in Xcode

I am attempting to get the disolve plugin to build and I keep getting an error inside the Dissolve.ccp file

This is the line that is giving me an error

gFilterRecord = filterRecord;

and this is the error that is poping up

Invalid conversion from 'void*' to 'FilterRecord*'

I am using Xcode version 3.2.6 and I am working with OSX 10.6.8

Thanks for any help,

-Tim
