HICococaView does not compile with GCC 4.2

Question

We have a large Carbon-based application (PowerPlant), which we are finally looking for for porting to Cocoa. We will do this gradually, and the first step is to try to get a Cocoa view in the Carbon window.

The problem is that when I use any of the functions from HICocoaView.h, the application will not compile unless I switch the compiler from GCC 4.2 to GCC 4.0.

Using any compiler other than GCC 4.0, I get an error in Xcode that functions are not available, for example. "HICocoaViewCreate is not available."

I can’t understand why this will not work, do we need to switch to the old compiler or are there any settings that we can change in order to compile them?

Any help or pointers to helpful documentation on porting Carbon to Cocoa is welcome. I read the old Carbon Cocoa integration guide, but it doesn't mention it.

HICocoaView.h 10.5, 10.6 SDK:

#if !__LP64__
extern OSStatus
HICocoaViewCreate(
  NSView *     inNSView,        /* can be NULL */
  OptionBits   inOptions,
  HIViewRef *  outHIView)                                                       AVAILABLE_MAC_OS_X_VERSION_10_5_AND_LATER;
…
#endif  /* !__LP64__ */
