[cl-opengl-devel] Helping out from OSX

[Sean Charles]

I am sure the thing that stopped me was not being able to call  
NSApplicationInit()... I did manage to get something going but it  
kept dropping out with an error, which, on looking it up said I had  
to call NSApplicationInit() but my CFFI experience is limited and I  
couldn't work out how to do it.

I looked at Verrazano as well but in the end time pressures made me  
go for X11. It just worked, I had to make a small change to get it to  
work on an intel mac though if I remember I just modded the  
library.lisp file a bit. My finally chaotic glut def looks like:

(define-foreign-library glut
   ;;-- (sjc-03-jul-06) -- added this line to ensure my locally built
   ;;-- OpenGLUT library is loaded as the "glut" library!
   ;;
   ;; (1) /usr/local/lib/libopenglut.dylib  => my build from OpenGLUT  
source package.
   ;; (2) /sw/lib/libglut.dylib => FINK installation of 3.7-1025
   ;;
   ;; Q. Which one is 'better' to use, if any ?!
   ;;    (1) because (2) doesn't have glutLeaveMainLoop etc !!!
   ;;
   ;((:and :darwin :x86) "/sw/lib/libglut.dylib")
   ((:and :darwin :x86) "/usr/local/lib/libopenglut.dylib")
   ;((:and :darwin :x86) (:framework "GLUT"))
   ;(:darwin (:or "libglut.dylib" "libglut.3.dylib" #-(and) 
(:framework "GLUT")))
   (:windows "freeglut.dll") ; XXX: is this right?
   (:unix (:or "libglut.so" "libglut.so.3")))

which, removing the chaff leaves this, I added the :x86 to make it  
intel friendly!

(define-foreign-library glut
   ((:and :darwin :x86) "/usr/local/lib/libopenglut.dylib")
   (:windows "freeglut.dll") ; XXX: is this right?
   (:unix (:or "libglut.so" "libglut.so.3")))
