I'm new to iPhone development and I'm having trouble using the 3rd part Kal framework in my project. I can't find any documentation on how to add the Kal framework to my code, so I assumed it was just a matter of adding the source files to my project's "Groups and Files" and set the Header file search path to include the new code.

1. Is that all I need to do to properly add the Kal framework to my iPhone project?

2. I'm getting this error (shown below), what is it indicating?

   Undefined symbols: ".objc_class_name_KalViewController", referenced from: literal-pointer@__OBJC@__cls_refs@KalViewController in RootViewController.o ld: symbol(s) not found

   I get this error when I add the statement...

   kalViewController = [[[KalViewController alloc] init] autorelease];

   to my RootViewController.m viewDidLoad method and #import "Kal.h"

Thanks so much for your help!
