This is the class of condition signaled if during the compilation of a file, the compiler notices a call to a function not defined (previously or in the file), it prints a warning that the function is called but not yet defined. (It is not an error to compile a function that calls a not-yet-defined function, of course. The warning is often useful, however, when the function name is typed incorrectly or the user believes a function is defined when it is not.)
This condition will also be signaled when an operator defined at the top-level calling undefined functions is compiled.
Here is an example:
;; The file foo.cl contains the following. Note the call to BAR. (in-package :user) (defun foo (x) (bar x)) ;; Here is what happens when we compile the file: USER(1): (compile-file "foo.cl") ; --- Compiling file /net/rubix/usr/tech/dm/foo.cl --- ; Compiling FOO ; Writing fasl file "/net/rubix/usr/tech/dm/foo.fasl" ; Fasl write complete Warning: The following undefined functions were referenced in the compilation: (BAR) #p"/net/rubix/usr/tech/dm/foo.fasl" NIL NIL USER(2):
If multiple calls to compile-file are part of the body of a with-compilation-unit form, no undefined function warning will be signaled when a function called in one file is defined in a later file.
