Dear list,
Long time no hear ;) Today I believe I've run into what might be a
bug with cl-glut while trying to SAVE-LISP-AND-DIE on sbcl 1.0.15.
Running a core saved with cl-glut and my program resulted in freeglut
errors like:
freeglut ERROR: Function <glutCreateWindow> called without first
calling 'glutInit'.
_3b on #lisp (Bart B?) though (glut:init) might need to be called on
when the core is loaded. When I tried this I got dumped to ldb
immediately with illegal pointer errors. I am unsure of the quality of
my fix, but I added the following to my :toplevel function and
everything worked.
(eval-when (:load-toplevel :execute)
(setf glut::*argcp* (cffi:null-pointer)
glut::*argv* (cffi:null-pointer))
(glut:init))
Saving the core also saves the pointer values of *argcp* and *argv* at
the time of saving. If this is The Right Way, I can try writing it up
to be put in init.lisp proper...
