Hello,

After upgrading AUCTeX using ELPA to version 12.1.2 it stopped working
with the following error (after trying to turn on the latex-mode):

  TeX-shdex-eval: Invalid dialect expression : :classopt.

I am using GNU Emacs 25.2.1 (x86_64-w64-mingw32) of 2017-04-24

It seems that you are using unupdated tex.el or tex.elc.  The
possibilities I can think of now are:
(1) Updating from ELPA is not complete for some reason, or
(2) In somewhere in the load-path of your emacs, stale version of
tex.el or tex.elc (or both) is left behind and used instead of the
updated one(s), or
(3) The elisp variable `TeX-style-hook-dialect-weight-alist' is
overwritten for some reason.

Can you first try updating from ELPA again?  If that doesn't resolve the
problem, please include the output of M-x TeX-submit-bug-report in your
reply.

Thankfully I use version of GNU Emacs with AUCTeX preinstalled,
so uninstalling ELPA version made AUCTeX work as workaround
(AUCTeX-date "2017-06-03", from
https://vigou3.github.io/emacs-modified-windows/)

Possible, as at the time of bug I have had both 12.1.2 and 12.1.1
marked as installed in the list of packages, the second one marked
as obsolete.

It worked after installing package from ELPA (maybe).
Unfortunately the error persists (after restarting Emacs), this time as

  File mode specification error: (error Invalid dialect expression : :classopt.)
  File local-variables error: (error Invalid dialect expression : :classopt.)
.
when loading file, and

  TeX-shdex-eval: Invalid dialect expression : :classopt.

after `M-x LaTeX-mode`.

Font lock works, for some strange reason.

There was problem with that idea, as `M-x TeX-submit-bug-report` didn't
work either with the same problem (but in different command).  Now it works:

Preinstalled version.  Well, that seems to be the reason of fail.
Having a look at the page linked from the page presented above, the
site-start.el file[1] contains lines
----------------------------------------------------------------------
(load "auctex.el" nil t t)
(load "preview-latex.el" nil t t)
----------------------------------------------------------------------
.  This indicates that the preinstalled AUCTeX was not installed from
ELPA, but by the traditional configure-make-make_install method.  Then,
installing from ELPA doubles the instance of AUCTeX and they conflict to
each other.

If you still want to use the updated version from ELPA, it is necessary
to do either of the following two options:
1. Uninstall the preinstalled version of AUCTeX before using ELPA
2. Perform the configure-make-make_install method for the development
   version of AUCTeX source taken from the git repository, after
   installing unix-like shell on your windows.

The option 1 consists of removing all the AUCTeX-related files and the
activation codes quoted above from your PC.

Ikumi Keita

Unfortunately it turned out not to be the (easy solved) case.

I tried to use this solution, but it didn't work
(perhaps I did something wrong?).

Thus I have commented out the following lines in
c:/Program Files/GNU Emacs 25.2/share/emacs/site-list/site-start.el

  ; (load "auctex.el" nil t t)
  ; (load "preview-latex.el" nil t t)

I have also renamed site-list/auctex directory to site-list/auctex-old.
This I think should make Emacs use ELPA-provided AUCTeX, isn't it?

Unfortunately, it didn't work. Here is full backtrace
(from debug-on-error):

(error "Invalid dialect expression : :classopt.")
  signal(error ("Invalid dialect expression : :classopt."))
  error("Invalid dialect expression : %S." :classopt)

OK.  (I think "site-list" is actually "site-lisp", but that doesn't
matter.)

> I have also renamed site-list/auctex directory to site-list/auctex-old.

OK.

> This I think should make Emacs use ELPA-provided AUCTeX, isn't it?

There still must be other files which are part of the preinstalled
AUCTeX, namely "tex-site.el" and "auctex.el", in
c:/Program Files/GNU Emacs 25.2/share/emacs/site-lisp/
.  So you should remove them as well.

> Unfortunately, it didn't work. Here is full backtrace

It seems that the conflict between the two versions of AUCTeX still
remains.  It's rather strange.  Even if the above two files are left
behind, the old version of tex.el(c) should not be loaded since they are
evacuated into site-lisp/auctex-old, outside of the load-path...

Did you terminate and restart the emacs session after uninstalling the
preinstalled AUCTeX?  The state of confilict persists until the emacs is
terminated.

This is not a major topic, but there are still other files which belong
to the preinstalled AUCTeX, I suppose.  They are info files auctex-info,
auctex-info-1, auctex-info-2 and preview-latex.info.  If they remain in
your PC, you might be presented with a bit old info file on some other
day, so I recommend to remove them, as well as to edit the "dir" file to
remove the entries of AUCTeX and preview-latex in it.  The "dir" is
located in, probably,
c:/Program Files/GNU Emacs 25.2/share/info/
.

Ikumi Keita

Ah, no, they ARE in the load-path, thanks to the subdirs.el.  Jakub,
please move the subdirectory "auctex-old" outside of the site-lisp.

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

No further comments, therefore I'm closing this report.
