Thank all you guys for the advices.
I see. Macroexpansion before compilation. Then, at that moment, macro-defined couldn't find function-defined... I never imagined that. I appreciate you all to telling me that.
I will check how to use eval-when. Thank you very much.
Also, C-u RET solves reader macro issue.
Thanks a lot.

Yes, but it's needed "during macroexpansion". If you only compile a function you can't call it yet.
You could try to just load it with C-c C-l. Then every toplevel form is evaluated immediately and available in the following forms. But there are also other missing function like SYMB and FLATTEN.
So I check sbcl repl directly on my bash; in that case, the file could be loaded and compiled without any problem. Therefore, SLIME must have the problem.
If you load it before compiling it you make all definitions available for macroexpansion. If you execute (load (compile-file "lol.chatper_2.lisp")) in a clean session you'll will most likely see the same problem.
Actually, if I made the function on REPL on SLIME, NO PROBLEM. The
problem is
occured when I made a file, load, and compile THE FILE.
I checked the file, then I found both g!-symbol-p and
o!-symbol-to-g!-symbol
are not recognized by SLIME, either. Then, I concluded functions with "!" are not recognized by SLIME.
Is there any solution about that? I use Ubuntu 9.10, SBCL and Emacs 23 provided by Ubuntu. Also I use cvs version of SLIME(newest).
When you get more experienced you'll recognize that you need EVAL-WHEN in situations like these. You will also learn the value of adding an IN-PACKAGE form at the beginning of a file.
P.S. I also found SLIME's REPL don't recognized reader macros. Though
making
reader macro with #foo, SLIME says something like "incomplete input".
Well, yes, SLIME assumes that you want to enter Lisp syntax not some random character noise. C-u RET will accept the current input anyway even if it doesn't look like a complete form.
