I get this error when I try to use SLIME with SBCL:

Lisp connection closed unexpectedly: connection broken by remote peer

That is the Emacs message. In the *inferior-lisp* buffer, this is displayed:

--

WARNING: These Swank interfaces are unimplemented: (ACTIVATE-STEPPING CALLS-WHO DISASSEMBLE-FRAME INSPECT-FOR-EMACS SLDB-BREAK-AT-START SLDB-BREAK-ON-RETURN WHO-BINDS WHO-CALLS WHO-MACROEXPANDS WHO-REFERENCES WHO-SETS WHO-SPECIALIZES) T * ;; Swank started at port: 32794.

NIL * Process inferior-lisp hangup

--

I load slime with a small function of mine:

(defun slime-load () (interactive) (add-to-list 'load-path "~/pgm/slime/") ; your SLIME directory ;; (setq inferior-lisp-program "/usr/bin/clisp") ; your Lisp system (setq inferior-lisp-program "/usr/local/bin/sbcl") ; your Lisp system (require 'slime) (slime-setup))

As you can see, I have used CLISP too, and that works (I changed the inferior-lisp-program variable just now and tested).

What could be the problem here?

When Googling I mostly found issues with sbcl running remotely, which is not an issue in my case.

Thanks!
