OK, my opengl demo now runs via CFFI bindings on clisp/win32. (a) I had to rearrange things so libraries get loaded during the ASDF build, before any bindings for said libraries do. (b) The CLisp equivalent of Lispworks's make-pointer is unsigned-foreign-address, which was necessary to pass an enum as a pointer argument (odd Glut/win32 issue). Congrats, I will now do a (favorable) Google mentor evaluation for CFFI-luis. -- Kenny Why Lisp? http://wiki.alu.org/RtL_Highlight_Film "I've wrestled with reality for 35 years, Doctor, and I'm happy to state I finally won out over it."
