Obj-C in C++ code

Hi all, I've been trying like hell to get this to work with no luck.  I've been trying to use some of Apple's sample code as a starting point for drawing fonts in a GL context (like GLString in the NSGLImage sample).  But I'm wanting to call those functions from within a c++ class.  I'm sure that I'll need some sort of wrapper functions but I'm getting around 9800 errors from within Cocoa classes.  I'm currently using 10.4 with Xcode 2.0 and cross developing for 10.3-10.4, I also got these errors under Xcode 1.5 and 10.3.9.

Here is a snippet of the errors.

Any help would be greatly appreciated.

Thanks!
