Question

The following code compiles fine when compiling as Mac OSX 10.6 as the active SDK (linked with the 10.5 frameworks, 10.5 set as the base SDK)

IOBluetoothHostController *controller = [IOBluetoothHostController defaultController];

However, if I compile it with Mac OSX 10.5 as the active SDK, I get an error message saying that IOBluetoothHostController is undeclared. How can I resolve this?

Answer 1

The problem is that the IOBluetoothHostController.h header is wrapped in:

#if BLUETOOTH_VERSION_MAX_ALLOWED >= BLUETOOTH_VERSION_2_0

I’m not sure exactly what’s going on there, but I was able to get the header included by specifying:

#define BLUETOOTH_VERSION_USE_CURRENT 

in my prefix header.
