[Bese-devel] compile-op error on backtracking.lisp

[Dan Beauchesne]

Hi all,

Please bear with me, I'm new to lisp.

My setup:
SBCL 0.9.13.30 (on debian etch)
ucw_dev latest (ie. today)

I've downloaded all the UCW dependencies and made sure they are
loadable by ASDF. When I try to load the start.lisp file, it seems to
be going fine for some time and then the slime debugger pops up with a
compile-op error on backtracking.lisp.

So when I do a (compile-file "/path/to/rerl/backtracking.lisp")
I get:

I have a feeling this is just a stupid error on my part, as ucw-boxset
works just fine. But after double-checking my dependencies and
re-reading the README, I'm not sure what it is.

Thanks guys
