Hello, since quite some time I am not able to run SLIME together with SBCL anymore. I did not care too much, since CMUCL and Allegro worked. However, I now am looking again at using OS threads on Linux/AMD64, and SBCL is my only option here. So I am interested to get it working again. Thus, I downloaded sbcl-0.9.9-x86-64-linux, CVS slime from today (Emacs on this machine is version 21.4.1), and did the usual installation as (add-to-list 'load-path PATH-TO-SLIME) (require 'slime) (slime-setup) Unfortunately, M-x slime does not succeed. The inferior-lisp buffer shows: 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: 34981. NIL * Process inferior-lisp hangup Can anyone help me? Thank you very much, Nicolas.
