After adding the following code in my .emacs file, comes up some error during startup of emacs. I am a newbie of emacs, is there some one can help me figure out where are the errors come from?

Added code in .emacs:

;; Auto-saving the Desktop
(require 'desktop)
(desktop-save-mode 1)
(defun my-desktop-save ()
  (interactive)
  ;; Don't call desktop-save-in-desktop-dir, as it prints a message.
  (if (eq (desktop-owner) (emacs-pid))
      (desktop-save desktop-dirname)))
(add-hook 'auto-save-hook 'my-desktop-save)

Errors:

    Looking at the function definition for what’s breaking, it seems that the error is that prj-file is NIL in line 492. (The other expand-filename call in the function shouldn’t ever have a nil, since it’s the car of a non-nil list of filenames).

    Now, prj-file is the first filename in /home/shenyan/Test/memcached-1.4.11 matching the regexp "\\(Root\\)?ProjStep.ede" and presumably there isn’t one. Since memcached presumably doesn’t have an EDE project file, what’s gone wrong must be that line 508’s call to ede-project-p did something weird when called with this subdirectory of /home/shenyan/Test/.

    I can’t work out exactly why that happened, but you can debug things quite easily. First bring up your *scratch* buffer to type emacs lisp easily. To check my guess, insert the following code into the buffer

    (ede-directory-project-p "/home/shenyan/Test/memcached-1.4.11")

    and run it by hitting C-x C-e with cursor on the closing bracket. If it returns nil I was wrong. Otherwise, you’ve found the culprit and should probably debug it further by hunting through the bits of ede-directory-project-p in ede-files.el.

    Probably what’s going on is that your /home/shenyan/Test/ directory has something that tells EDE to search subdirectories (or maybe that’s the default?) and then the memcached subdirectory has a file whose name makes EDE think it should be searched for a project file. If you work out exactly what happened, you might consider submitting a bug to the EDE developers: they probably shouldn’t error out if the project file doesn’t exist.
