Custom c++ ConsoleFunction

Hi,

i add the following function to the engine
ConsoleFunction(helloWorld, void, 1, 1, "A simple test function.")
{
Con::printf("Hello World!");
}

then i build it in xcode.

now i want to execute this function from within the console so i launch iTGB again
and hit F5 to execute the simulator.(iTGB simulator)
then i open the console with ~ (tild)
and there i type: hello();

the console complain that theres no such function.

please help.
