nice, something real to test it on. :)

After ./configure, in include/Make/Platform.make what do these settings say?

#OpenCL
OCLINCPATH          = 
OCLLIBPATH          = 
OCLLIB              = 
USE_OPENCL          = 

If it is set ok there then we need to do something more than just set
   EXTRA_INC = $(PROJINC) $(OCLINCPATH)
in r.sun's Makefile.

re. the libs, see also the "needed?" comment in the Makefile. Maybe
one of those need to be enabled.


thanks,
Hamish
