[cl-gd-devel] CL-GD on 64-bit Lisp problem

[Jeffrey Cunningham]

Thank you for the help, Hans. That was just an experiment. Normally, I  
load UFFI. But you said something that made me go back and look at my sbcl  
executable. Turns out I somehow built a 32-bit sbcl on this 64-bit  
machine. That explains everything (except why it built sbcl that way).

So it's clearly not a CL-GD issue at all.
Thanks again,

--Jeff
