The first thing to do it to learn how to search the mailine list 
archive. For example try to search for iPhone and NDA:

http://www.cocoabuilder.com/search/archive/cocoa?words=iphone+nda

Then try to compile your file as an obj-c++ file and not as a C++ 
file. To do this, rename it using the .mm extension (instead of .m 
or .cpp).
