elisp byte compilation problem

elisp byte compilation problem

[Javier Oviedo]

Hello all.

I have found some strange behavior when I compile certain elisp files and
then load them...

=============================
One example is clearcase.el. I have (require 'clearcase) in my .emacs file.
Without byte compiling everything works fine...meaning that I in the menubar
there is a clearcase menu that I can access without problem. As soon as I
byte compile, the clearcase menu disappears from the menu bar. I can't
explain this. I know very little about elisp and therefore need some help.

ctypes.el size is 260598
ctypes.elc size if 632  ==> something is wrong here.
=============================
Another example is with ctype.el. I have the following in my .emacs file:
  (require 'ctypes)
  (setq ctypes-write-types-at-exit t)
  (ctypes-read-file "C:/data/joviedo/Emacs/site-lisp_21_2/_ctypes" nil t t)
  (ctypes-auto-parse-mode 1)

When ctypes in not byte compiled, everything works fine. With ctypes byte
compiled I get the following error when I load a file...

File mode specification error: (void-function ctypes-read-file)
run-hooks: Symbol's function definition is void: ctypes-find-file-hook

ctypes.el size is 62607
ctypes.elc size if 814  ==> something is wrong here.
=============================

I am using Emacs 21.2 on WinXP

Thanks In Advance!

I just discovered that for almost any .el I compile I see problems. Since I
hardly change things outside of my .emacs most of my .elc  files have been
around for some time...I am just noticing this problem now.

I had to re-byte compile folding.el(I have had byte compiled for the last
year and had no problems) after making a one line change. The .elc size
dropped from 84,072 bytes to 607 bytes. Obviously, something is wrong with
the byte compilation itself.

What could be going on here? Thanks!!

What does the *Messages* buffer say after you do M-x
byte-compile-file RET?  What does the *.elc file contain after this?

These errors did not start happening until recently...

I byte compiled folding.el and I see the following in the *Messages* buffer:

Compiling c:/data/joviedo/Emacs/site-lisp_21_2/folding.el...
Folding buffer... done
Folding buffer... done
File local-variables error: (error "Local variables entry is missing the
prefix")
Compiling c:/data/joviedo/Emacs/site-lisp_21_2/folding.el...done
Wrote c:/data/joviedo/Emacs/site-lisp_21_2/folding.elc
Byte-Compile: 1 file.

The folding.elc file shows the following:

;ELC\x14
;;; Compiled by a0850403@GT64V7121 on Fri May 23 09:35:11 2003

;;; in Emacs version 21.2.1
;;; with bytecomp version 2.85

;;; This file uses dynamic docstrings, first added in Emacs 19.29.
(if (and (boundp 'emacs-version)
  (< (aref emacs-version (1- (length emacs-version))) ?A)

      (string-lessp emacs-version "19.29")))
    (error "`folding.el' was compiled for Emacs 19.29 or later"))

Thanks for your help!

Okay, now show us the last few lines of the file folding.el.  I think
the file contains the words "Local Variables" near the end -- show us
that line and the rest of the file.

Well, what does the file-local variables section of folding.el look like?

I'm sorry but I'm not sure if I'm giving the correct info, but here goes...I
did a occur on "local-variables" and this is what I get:

Why would there not be an error when using .el version if something is truly
wrong with a local-variable? Thanks.

Search for the string "Local variables:", including the colon but
without the quotes.  You will see that it occurs twice.  The first
occurrence is missing the "end" line.  I guess it confuses Emacs.

I propose to replace the first "Local variables:" with 
"Local\ variables:" which should mask the problem.  Also, maybe
suggest to the author to make this change and to add an "end:" line
to that snippet.

I added the backslash and it had no affect. What else could be going wrong?
