Hello Helmut,
I've recently become aware the slime is now on github, so I downloaded and installed a copy. It ran, but there is a window in my copy of emacs-23.4.1 filled with warnings related to ert.el which indicate that it can't be found.
A list of the warnings: Warning (emacs): No ert.el found: not defining test symbol-at-point.2 Warning (emacs): No ert.el found: not defining test symbol-at-point.3 Warning (emacs): No ert.el found: not defining test symbol-at-point.4 Warning (emacs): No ert.el found: not defining test symbol-at-point.5 Warning (emacs): No ert.el found: not defining test symbol-at-point.6 Warning (emacs): No ert.el found: not defining test symbol-at-point.7 Warning (emacs): No ert.el found: not defining test symbol-at-point.9 Warning (emacs): No ert.el found: not defining test symbol-at-point.10 Warning (emacs): No ert.el found: not defining test symbol-at-point.11 Warning (emacs): No ert.el found: not defining test symbol-at-point.12 Warning (emacs): No ert.el found: not defining test symbol-at-point.13 Warning (emacs): No ert.el found: not defining test symbol-at-point.14 Warning (emacs): No ert.el found: not defining test symbol-at-point.15 Warning (emacs): No ert.el found: not defining test symbol-at-point.16 Warning (emacs): No ert.el found: not defining test sexp-at-point.1 Warning (emacs): No ert.el found: not defining test narrowing Warning (emacs): No ert.el found: not defining test find-definition Warning (emacs): No ert.el found: not defining test (find-definition.2 (:fails-for allegro lispworks)) Warning (emacs): No ert.el found: not defining test (find-definition.3 (:fails-for abcl allegro clisp lispworks sbcl ecl)) Warning (emacs): No ert.el found: not defining test complete-symbol Warning (emacs): No ert.el found: not defining test arglist Warning (emacs): No ert.el found: not defining test (compile-defun (:fails-for allegro lispworks clisp ccl)) Warning (emacs): No ert.el found: not defining test (compile-file (:fails-for allegro lispworks clisp)) Warning (emacs): No ert.el found: not defining test utf-8-source Warning (emacs): No ert.el found: not defining test async-eval-debugging Warning (emacs): No ert.el found: not defining test unwind-to-previous-sldb-level Warning (emacs): No ert.el found: not defining test loop-interrupt-quit Warning (emacs): No ert.el found: not defining test loop-interrupt-continue-interrupt-quit Warning (emacs): No ert.el found: not defining test interactive-eval Warning (emacs): No ert.el found: not defining test report-condition-with-circular-list Warning (emacs): No ert.el found: not defining test interrupt-bubbling-idiot Warning (emacs): No ert.el found: not defining test (interrupt-encode-message (:style :sigio)) Warning (emacs): No ert.el found: not defining test inspector Warning (emacs): No ert.el found: not defining test macroexpand Warning (emacs): No ert.el found: not defining test indentation Warning (emacs): No ert.el found: not defining test break Warning (emacs): No ert.el found: not defining test (break2 (:fails-for cmucl allegro ccl)) Warning (emacs): No ert.el found: not defining test locally-bound-debugger-hook Warning (emacs): No ert.el found: not defining test end-of-file Warning (emacs): No ert.el found: not defining test interrupt-at-toplevel Warning (emacs): No ert.el found: not defining test interrupt-in-debugger Warning (emacs): No ert.el found: not defining test flow-control Warning (emacs): No ert.el found: not defining test sbcl-world-lock Warning (emacs): No ert.el found: not defining test (disconnect-one-connection (:style :spawn)) Warning (emacs): No ert.el found: not defining test disconnect-and-reconnect Warning (emacs): No ert.el found: not defining test package-updating Warning (emacs): No ert.el found: not defining test repl-test Warning (emacs): No ert.el found: not defining test (repl-test-2 (:fails-for allegro)) Warning (emacs): No ert.el found: not defining test repl-return Warning (emacs): No ert.el found: not defining test repl-read Warning (emacs): No ert.el found: not defining test repl-read-lines Warning (emacs): No ert.el found: not defining test repl-type-ahead Warning (emacs): No ert.el found: not defining test interrupt-in-blocking-read Warning (emacs): No ert.el found: not defining test move-around-and-be-nasty Warning (emacs): No ert.el found: not defining test form-up-to-point.1 Warning (emacs): No ert.el found: not defining test complete-symbol* Warning (emacs): No ert.el found: not defining test complete-form Warning (emacs): No ert.el found: not defining test font-lock-magic Warning (emacs): No ert.el found: not defining test enclosing-context.1 Warning (emacs): No ert.el found: not defining test find-local-definitions.1
I looked around for a copy of ert.el and ert-x.el and I found a couple of files that looked reasonable, but they won't load so I wonder if you know how to get those files that are compatible with emacs-23.4.1?
The github copy of slime seems to load OK, but I haven't really tried using it for development with the warnings I was getting.
Thanks in advance,
