#import in ios? Protobuf c++ in ios

Question

I am trying to get protobuf into xcode 4 and work with ios 5. I've done other tutorials none have worked. I have used a script to compile the libraries into arm 7 architecture and then added them to my project. This is the only thing that has worked so far.

My issue now is that I am trying to use the c++ generated files; however, I am getting an error saying #include -> lexical or preprocessor issue.

Any tips? It only showed this when I tried to run my project on the ipad. Before, it was fine with it.

Thanks. :)

#include <google/protobuf/repeated_field.h>

Update: This only breaks when I include it in an obj c file. I can make a Demo.h and include addressbook. Why can't I include addressbook.pb.h into an obj c file? Am I missing a setting somewhere? Which one?
