You are explicitly invoking foo here.
The only difference between (defun ...) and (foo ...) in
any file that you require or load is in your mind.
They are just functions to be executed.  Lisp doesn't
care if they are named def<something> or not.

To achieve what you seem to want you need:

---x---
(defun foo ()
  (error "Shouldn't hit this when compiling"))
(provide 'x)
---a---
(require 'x)
(foo)
(provide 'a)
---b---
