I would like to build Closure, play around with it and if possible contribute to its progress. However, I cannot seem to build it with either cmucl or sbcl. It appears from the mailing list that both should work. (I am running it on Debian x86 with cmucl 19d-20061116-1 and sbcl 0.9.16.0-1) To start with, I checked out the source from CVS then tried to build: CVSROOT=:pserver:anonymous@common-lisp.net:/project/closure/cvsroot cvs login # passwd anonymous cvs co -P closure ---------------- In cmucl: # ./BUILD <stuff elided> ; Warning: This function is undefined: ; OOS Error in KERNEL:%COERCE-TO-FUNCTION: the function OOS is undefined.
