let: Symbol's function definition is void: macroexpand-1

[john1726]

Please note that I have added the following files to emacs:

unicode-fonts.el
font-utils.el
ucs-utils.el
list-utils.el

Why I try to re-load my .emacs, this is the error I'm getting:

let: Symbol's function definition is void: macroexpand-1

Based on your quickstarts, this is what I have added to my .emacs:

;;
(require 'list-utils)

(list-utils-flatten '(1 2 (3 4 (5 6 7))))
;; '(1 2 3 4 5 6 7)

(list-utils-depth '(1 2 (3 4 (5 6 7))))
;; 3

(let ((cyclic-list '(1 2 3 4 5 6 7)))
  (nconc cyclic-list (cdr cyclic-list))
  (list-utils-make-linear-inplace cyclic-list))
;; '(1 2 3 4 5 6 7)

(list-utils-cyclic-p '(1 2 3))
;; nil

(list-utils-plist-del '(:one 1 :two 2 :three 3) :two)
;; '(:one 1 :three 3)

;;

(require 'ucs-utils)

(ucs-utils-char "Middle Dot"         ; character to return
                ?.                   ; fallback if unavailable
                'char-displayable-p) ; test for character to pass

(ucs-utils-first-existing-char '("White Bullet"
                                 "Bullet Operator"
                                 "Circled Bullet"
                                 "Middle Dot"
                                 ?.) 'cdp)

(ucs-utils-string "Horizontal Ellipsis" '[["..."]])

;;

(require 'font-utils)
(font-utils-exists-p "Courier")

;;

(require 'unicode-fonts)
(unicode-fonts-setup)

Do you have any suggestions? TIA.
