[Openmcl-devel] Quartz not working in v1.10

[Ron Garret]

I think I’ve figured out what is going on.

Welcome to Clozure Common Lisp Version 1.10-r16304M  (DarwinX8664)!
? (objc:load-framework "Quartz" :quartz)
NIL
? (fboundp '#/pageAtIndex:)
NIL
? (unintern '#/pageAtIndex: 'nsfun)
T
? (fboundp '#/pageAtIndex:)
#<OBJC-DISPATCH-FUNCTION NEXTSTEP-FUNCTIONS:|pageAtIndex:| #x302001413D1F>
? 

Apparently, the binding of objc functions to their symbols happens at when the symbol is initially interned.  Somehow my image got built with pageAtIndex: already interned in the nsfun package (how that happened I still don’t know) which causes the function binding to not happen when it is supposed to.

Interestingly, the function binding seems to be a one-shot deal.  If you try to repeat the process, it fails:

? (unintern '#/pageAtIndex: 'nsfun)
T
? (fboundp '#/pageAtIndex:)
NIL
? (objc:load-framework "Quartz" :quartz)
NIL
? (fboundp '#/pageAtIndex:)
NIL
? (unintern '#/pageAtIndex: 'nsfun)
T
? (fboundp '#/pageAtIndex:)
NIL
? 

AFAICT if you ever get into this state you are irrecoverably hosed.
