This is a function declaration.

You don't get this error from the declaration, you get this error
where you try to call the function, and you haven't shown the call so
it's difficult to say what the problem is.

What is the type of theClass->constructor ?
Is it a static member function?
Does it help if you change the call to use &theClass->constructor instead?
