How to resolve `file missing` error when autoloading in Emacs?-CodePudding

I'm running into this error when trying to load an auto generated autoload.el file using loaddefs-generate function. The following is how I did

;;; core-autoload.el -*- lexical-binding: t; -*-

(defvar generated-autoload-file nil
  "This is neccessary, otherwise raise error.
`Defining as dynamic an already lexical var`.")

(defvar chidori-autoload-file
  (expand-file-name "autoload.el" chidori-cache-dir)
  "Autoload file.")

(defun chidori-autoload/generate-define (loaddef &rest DIRS)
  "LOADDEF DIRS."
  (let ((generated-autoload-file loaddef))
    (when (or (not (file-exists-p generated-autoload-file))
              noninteractive)
      (loaddefs-generate DIRS chidori-autoload-file))))

(defun chidori-autoload/reload ()
  "Generate autoload file from `core/autoload'."
  (interactive)
  (when (file-exists-p chidori-autoload-file)
    (delete-file chidori-autoload-file t)
    (message "delete old autoload file: %s" chidori-autoload-file))

  (chidori-autoload/generate-define chidori-autoload-file chidori-autoload-dir)
  (load chidori-autoload-file nil 'nomessage)
  (message "generate autoload file: %s done." chidori-autoload-file))

(unless (file-exists-p chidori-autoload-file)
  (chidori-autoload/reload))

(load chidori-autoload-file nil 'nomessage)

(provide 'core-autoload)
;; core-autoload.el ends here

And this is part of generated autoload file

;;; autoload.el --- automatically extracted autoloads (do not edit)   -*- lexical-binding: t -*-
;; Generated by the `loaddefs-generate' function.

;; This file is part of GNU Emacs.

;;; Code:
;;; Generated autoloads from ../../autoload/package.el

(autoload 'package! "../../autoload/package")

;;; and many other autoloads

However, when I start Emacs, the error occurred saying it (file-missing "Cannot open load file" "No such file or directory" "../../autoload/package"

If I manually edit to absolute path, the issue is gone. But I don't think it's right way to do.

Can anyone help me out?

My draft for further reference:

The following is my system information:

OS: macOS 12.6
Emacs versions: emacs-plus@29
Terminal: Wezterm
Shell: fish

CodePudding user response：

I finally figured out the issue.

In my config, I got

(defvar chidori-etc-dir (expand-file-name "etc/" user-emacs-directory))
(defvar chidori-cache-dir (expand-file-name "cache/" chidori-etc-dir))

The issue is fixed if I replace chidori-etc-dir with the following

(defvar chidori-cache-dir (expand-file-name "cache/" user-emacs-directory))

From my understanding, we couldn't 2 level nested dir for autoload file. This also happen if I write autoload file to user-emacs-directory.
