Hey, I am completly new to CL and Slime, so please bear with me. When I try a M-x slime RET in emacs 24, I get a new window/buffer (*inferior-lisp*). But that's it. I think Slime tries to initalize itself, but that process fails. This is the output: (progn (load "/usr/local/src/slime/swank-loader.lisp" :verbose t) (funcall (read-from-string "swank-loader:init")) (funcall (read-from-string "swank:start-server") "/tmp/slime.12226")) This is SBCL 1.0.55, an implementation of ANSI Common Lisp.
