I have just upgraded to CMUCL Snapshot 2005-10 (19C) and the latest SLIME CVS sources on my Linux box with GNU Emacs 21.3.2. Before trying SLIME with this new setup, I removed all fasl files from ~/.slime and the local SLIME sources in /home/paolo/src/slime. When I issue `M-x slime' from Emacs, I get this error in the echo area, and SLIME doesn't start: setq: Wrong type argument: listp, "cmucl -core /home/paolo/src/mcclim/clim.core" My ~/.swank.lisp: (setf (cdr (assoc 'swank::*print-pretty* swank:*sldb-printer-bindings*)) t) (load "/home/paolo/src/slime/present") My SLIME-related forms in ~/.emacs: (add-to-list 'load-path "/home/paolo/src/slime") (require 'slime) (setq slime-multiprocessing nil) (setq slime-truncate-lines nil) (slime-setup :autodoc t) (add-hook 'lisp-mode-hook (lambda () (set-fill-column 80) (auto-fill-mode) (setq indent-tabs-mode nil))) (add-hook 'inferior-lisp-mode-hook (lambda () (inferior-slime-mode t))) (setq inferior-lisp-program "cmucl") (slime-register-lisp-implementation "clim" (format "cmucl -core %s" (expand-file-name "~/src/mcclim/clim.core"))) (setq common-lisp-hyperspec-root "file:/home/paolo/doc/lisp/clhs/HyperSpec/") (add-hook 'inferior-lisp-mode-hook (defun my-inferior-lisp-mode-hook () (add-to-list (make-local-variable 'comint-output-filter-functions) (lambda (string) (unless (get-buffer-window (current-buffer) t) (display-buffer (current-buffer) t)) (comint-postoutput-scroll-to-bottom string))))) Any suggestions?
