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

[Hans Hübner]

Hi Jeff,

I have just tried :cl-gd on my Ubuntu 64 bit box with CCL.  Things
work as expected.  I have used quicklisp to load it.

The error message that you've pasted indicates that you have loaded
cffi-uffi-compat library.  Don't do that, use UFFI instead.

Anything else we can help with, let us know.
-Hans
