There are more up-to-date examples about using the Octave C++ API with respect 
to 'Da Coda Al Fine: Pushing Octave limits', for example in this presentation:

  http://wiki.octave.org/wiki/images/b/b0/Slides_octconf_gdf_jgh.pdf

I am also linking C++ applications to Octave on OSX, but I am using the 
standard GNU toolchain to accomplish this rather than XCode projects.

AFAIK there are no Octave developers who are experienced in using XCode, so I'm 
afraid you won't get much help in setting this thing up but, 
if you eventually manage to get it working, we would very much appreaciate you 
reporting back to share your experience, possibly documenting
your steps on a wiki page...

Best wishes,
