After using this for a while i’ve just realised that all output is going to the inferior-lisp buffer instead of the REPL.The solution is to go into the slime directory, open swank.lisp and find the lines:
(defvar *globally-redirect-io* nil
“When non-nil globally redirect all standard streams to Emacs.”)
and change them to
(defvar *globally-redirect-io* t
“When non-nil globally redirect all standard streams to Emacs.”)
Which appears to do the trick.
(Crosses fingers hopefully)
Cheers
