[Openmcl-devel] Cocoa on PPC32 ?

[Paul Krueger]

My recent re-build for PPC32 via the IDE also failed, but I was able  
to build it via the command line by allowing it to re-define a  
constant to a new value when the exception occurred:

Welcome to Clozure Common Lisp Version 1.3-RC1-r11875M  (DarwinPPC32)!
? (rebuild-ccl :full t)
Rebuilding Clozure Common Lisp using Version 1.3-RC1-r11875M   
(DarwinPPC32)
;Building lisp-kernel ...

...

I'm also routinely using Cocoa on PPC without problems.
