Re: Problem compiling Octave on Mac OS X

[Bernard Desgraupes]

I also stumbled recently into this recently. The problem is that the  
CoreGraphics framework is in the ApplicationServices framework and the  
latter is not passed to the linker.

You must modifiy the declaration of OCTINTERP_LINK_DEPS in the file  
src/Makefile.in (or directly in the Makefile if you do not want to  
regenerate everything).
Replace
OCTINTERP_LINK_DEPS = \
  -L../liboctave $(LIBOCTAVE) -L../libcruft $(LIBCRUFT) $(LIBS) $ 
(FLIBS) \
  $(OPENGL_LIBS)

by
OCTINTERP_LINK_DEPS = \
  -L../liboctave $(LIBOCTAVE) -L../libcruft $(LIBCRUFT) $(LIBS) $ 
(FLIBS) \
  $(OPENGL_LIBS) $(CARBON_LIBS)


Including (CARBON_LIBS) does the trick since it will automatically  
call the ApplicationServices headers and hence the CoreGraphics headers.

If you make this change in src/Makefile.in, you must re-run the  
configuration.

cheers,

Bernard
