I've recently updated SLIME from package-list-packages in Emacs. However, when I try to run it using M-x slime, I get this:
(progn (load "/home/koz/.emacs.d/elpa/slime-20140913.730/swank-loader.lisp" :verbose t) (funcall (read-from-string "swank-loader:init")) (funcall (read-from-string "swank:start-server") "/tmp/slime.3081"))
*
; loading #P"/home/koz/.emacs.d/elpa/slime-20140913.730/swank-loader.lisp"
;;
;; Error while compiling /home/koz/.emacs.d/elpa/slime-20140913.730/swank/backend.lisp:
;; Failed to find the TRUENAME of /home/koz/.emacs.d/elpa/slime-20140913.730/swank/backend.lisp:
;; No such file or directory
;; Aborting.
;; *
I still have a REPL afterwards, but I think this is very strange, and I'd like to know what's going on and why.
This is caused by losing the swank sub-directory in your slime folder. To fix it, you can simple download slime from github and copy the folder swank to your slime installed path, for your situation is /home/koz/.emacs.d/elpa/slime-20140913.730/ then restart your slime. it will be load correctly.
