obj-c++ namespaces

Hey all,

I'm getting the following errors while compiling obj-c++ files and
don't quite know what it means other than maybe somehow I can't use
the namespace from within the class interface, but then I just get
more questions on how it's supposed to be done.

ABCController.h:20: error: using-declaration for non-member at class scope
ABCController.h:20: confused by earlier errors, bailing out

I've tried forward declarations and so many combinations but nothing
seems to help. I am linking these files against a c++ *.dylib that has
the namespaces in it.

This error appears in the commented line below ...

--- *.h
#include "abc.h"

using namespace ABC;

@interface MyController : NSObject
{
   ABC::Pattern *pattern;
   ABC::Network *network;    // Error appears on this line when compiling
}

- (void)justDoit;

@end

// *.mm
#include "abc.h"

@implementation MyController

- (void)justDoIt
{
   NSMutableArray *dataPatterns;
      ...

   network = new ABC::Network(1, 2);

      ...
   pattern = (ABC::Pattern *) [[dataPatterns objectAtIndex:i)] pointerValue];
}

@end

Anyone have an idea what's going on here?
