Hello,
I'm a newcomer to Lisp ... and am running elisp on Linux. I have one
question:
After I load my program with (load "program_file"), I try to set up the
debugger with (debug-on-entry 'main_function). All I get, however, is:
Error: The function DEBUG-ON-ENTRY is undefined.
Error signalled by EVAL.
Broken at SYSTEM::BREAK-LEVEL. Type :H for Help.
Any suggestions?
Thanks,
DT

Maybe you are not giving the command to gnu-emacs "elisp", but to another
kind of lisp you are running as a subprocess in an emacs window?
The output is typical for a kind of common lisp, not elisp. If the window
says "inferior lisp" this is probably the case (the term is not express my
judgement of quality).
I normally start debugging in "elisp" by:
M-X debug-on-entry RETURN main_function RETURN
If you are running another lisp please specify its name, or try
(help 'step) or (help 'break)
