Hi Drew,

I installed Icicles in Emacs and Emacs put it in the
home/gfp/.config/emacs/elpa directory

but when I want to run it, it said:

did not find file/directory
(in German language: Datei oder Verzeichnis nicht gefunden, icicles-mac)

message:
Leaving directory ‘/home/gfp/.config/emacs/elpa/icicles-2022.1.26’
\f
Compiling file /home/gfp/.config/emacs/elpa/icicles-2022.1.26/icicles.el 
at Sun Jan 29 13:31:14 2023
Entering directory ‘/home/gfp/.config/emacs/elpa/icicles-2022.1.26/’
icicles.el:1695:16: Error: Cannot open load file: Datei oder Verzeichnis 
nicht gefunden, icicles-mac


How can I solve the problem?

Kind regards

Gottfried

You don't say exactly what you did.  Or what Emacs
version you have.

A guess is that you just didn't add the directory
where you have the source files to your value of
variable `load-path'.  Emacs can't know where to
find libraries if you don't tell it.

[ Caveat: I don't have or use Emacs 29, which includes
  native compilation, so I can't help you there -
  except to say that you can, I expect, still follow
  the regular directions (see below).  If it for some
  reason needs the macros file (`icicles-mac.el')
  loaded first, then do that. ]

Normally all you need to do is add the directory
where you have the Icicles files to the value of
your `load-path' variable:

(add-to-list 'load-path
             "/wherever/you/have/Icicles/files/")

Then (require 'icicles) or `M-x load-library icicles'.

This is described here:

https://www.emacswiki.org/emacs/Icicles#ObtainingAndInstalling
___

Of course, it's better to byte-compile the files,
if you want to do more than just give Icicles a
quick try.

You can byte-compile Icicles after you've loaded
it (source files).

Or you can do it anytime.  But you must always
have loaded `icicles-mac.el', to be able to
byte-compile any of the source files (including
`icicles-mac.el' itself).

This is described here:

https://www.emacswiki.org/emacs/Icicles_-_Libraries#byte-compile

E.g., just Dired the directory with the files,
mark them, and `B' to byte-compile them.
(After having loaded `icicles-mac.el'.)

You can see other reminders of the need to first
load `icicles-mac.el' in the source files.  E.g.:

;;  ******************
;;  NOTE: Whenever you update Icicles (i.e., download
;;  new versions of Icicles source files), I recommend
;;  that you do the following:
;;
;;      1. Delete all existing byte-compiled Icicles
;;         files (icicles*.elc).
;;      2. Load Icicles (`load-library' or `require').
;;      3. Byte-compile the source files.
;;
;;  In particular, always load `icicles-mac.el' (not
;;  `icicles-mac.elc') before you byte-compile new
;;  versions of the files, in case there have been any
;;  changes to Lisp macros (in `icicles-mac.el').
;;  ******************

(This isn't special to Icicles; it's just standard
Lisp practice.)
___

FYI: This is the code in `icicles.el' that loads
the other files when you load it:

;;; Load other Icicles files

(eval-when-compile
 (or (condition-case nil
         ;; Use load-library to ensure latest .elc.
         (load-library "icicles-mac")
       (error nil))
     ;; Require, so can load separately if not on `load-path'.
     (require 'icicles-mac)))

(require 'icicles-face)
(require 'icicles-opt)  ;; Requires face
(require 'icicles-var)  ;; Requires opt
(require 'icicles-fn)   ;; Requires mac, opt, var
(require 'icicles-mcmd) ;; Requires mac, opt, var, fn
(require 'icicles-cmd1) ;; Requires mac, opt, var, fn, mcmd
(require 'icicles-cmd2) ;; Requires mac, opt, var, fn, mcmd, cmd1
(require 'icicles-mode) ;; Requires mac, face, opt, cmd1, cmd2

HTH.  If you have some follow-up, I think you
can drop the ccing of help-gnu-emacs@gnu.org.

RE: [External] : icicles

[Drew Adams]

The byte-compiler warnings are benign - ignore them.
They're due to the library supporting also old Emacs
releases (including releases prior to the ability to
inhibit warnings).

(Please drop help-gnu-emacs@gnu.org from CC from now
on, if you reply with additional, specific Icicles
feedback.)
