Rename MyController.m to MyController.mm
gcc needs the .mm extension to guess that your file is objective-c++
code.

I'm trying to mix Objective-C with existing C++ files, but I'm having
some trouble getting XCode to compile the C++ source. I have a simple
object called TestCC that has an Add() method. When I #import TestCC.h
into MyController, it gives me the errors below.
TestCC.h:10: error: parse error before "TestCC"
TestCC.h:10: cannot find interface declaration for `MapController'
TestCC.h:11: error: syntax error before '{' token

Source...
// TestCC.h
class TestCC {
public:
TestCC();
int Add( int a, int b );
private:
};
---------------------------------------
// TestCC.cpp
#include "TestCC.h"
TestCC::TestCC() { }
int TestCC::Add( int a, int b ) {
return a + b;
}
---------------------------------------
// MyController.m
#import "TestCC.h"
@implementation MyController
- (IBAction)MyButtonClicked:(id)sender{ }
-----------------------------------------------------------
// MyController.h
#import <Cocoa/Cocoa.h>
@interface MyController : NSObject {
}
- (IBAction)MyButtonClicked:(id)sender;
@end
I've read what I could find online, and this seems to be the way to do
it, but XCode's not agreeing with me.
