Works for me with
- emacs 26.1
- slime 2.23
- clisp 2.49.93+

on Darwin and on Linux.

Add a ~/.swank.lisp file with a line such as:

#+clisp (defparameter swank:*use-dedicated-output-stream*  nil)

rlwrap shouldn’t be needed with clisp, since it can be compiled with readline. This is the reason why clisp is GPL!

This should not occur.



Since you don’t seem to have readline compiled in, perhaps you don’t have libsigsegv compiled in either?
I would advise you to recompile clisp with those essential libraries!

Have a look at the script I currently use to compile and install clisp from sources:
https://github.com/informatimago/install/blob/master/install-pjb-environment#L399
Don’t use this script indiscriminately, it installs a lot of things!!! Instead, copy and paste what you need.
