So I'd like to try out the new! improved! Celtk2 under Linux/SBCL, but<br>I'm having some installation problems. First I found that I had a<br>really old version of CFFI (thanks, Ubuntu!). After installing the<br>latest CFFI tarball, I still get the following error:

<br> Any hints on where to go next?</blockquote><div><br>Hmmm. (require :celtk)? Well, it got all the way up to tk-structs so i guess SBCL is smart enough to know what to do. To rule out an issue here, hop into celtk/load.lisp and start evaluating forms one by one. But really...
<br><br>That error has me concerned as to whether you have managed to get a clean CFFI environment. CFFI normally complains intelligently if I am off base, and that looks like an internals trip up. Might be a mismatch of old and new code.
<br><br>Meanwhile I will go stare at tk-structs and the CFFI source to see if I notice anything funny about :unsigned-longs.<br><br>kt<br><br><br> </div><br></div><br>
