I know this is an old post, but the problem, in my view, still exists.

AUTeX provides for customization for LaTeX-mode-hook, but inside the
function LaTeX-preview-setup in preview.el, it overwrites the value with
(remove-hook 'LaTeX-mode-hook #'LaTeX-preview-setup) (add-hook
'LaTeX-mode-hook #'preview-mode-setup).

Sorry, I misread the code snippet above; it doesn't seem to be the cause of
LaTeX-mode-hook being overwritten.

[Message part 1 (text/plain, inline)]

I've been exploring more.  Here is a summary of what I've found:

If I customize LaTeX-mode-hook and load a .tex file, the value of
`LaTeX-mode-hook' is wiped and replaced with only preview-mode-setup.

If I comment out the line

(add-hook 'LaTeX-mode-hook #'LaTeX-preview-setup)

in auctex-autoloads.el, the customized value of `LaTeX-mode-hook' is not
wiped.

If I change 

'(LaTeX-mode-hook '(flyspell-mode LaTeX-math-mode turn-on-reftex))

within (custom-set-variables.. in my init file to

'(LaTeX-mode-hook '(flyspell-mode LaTeX-math-mode turn-on-reftex) t)

the customized value is not wiped.

This "wiping" is strange.  `LaTeX-preview-setup' removes itself from
`LaTeX-mode-hook' and adds `preview-mode-setup' instead.  However, this
should not affect other functions which also happen to be added to
`LaTeX-mode-hook'.

I just tried with emacs 24.5 and ELPA AUCTeX 11.88.6.  My emacs just
contained

  (add-hook 'LaTeX-mode-hook (lambda () :test))

After emacs startup, the value of `LaTeX-mode-hook' was

  (LaTeX-preview-setup (lambda nil :test))

And after opening some tex file, the value was

  (preview-mode-setup (lambda nil :test))

So that's expected, and my test lambda didn't get wiped out.

Hm, the second version says that your customs should be set right NOW
and also made the default value of `LaTeX-mode-hook'.  The former will
apply the customization at some future point in time, I think after the
(defcustom LaTeX-mode-hook ...) form has been evaluated when AUCTeX
loads.

I can reproduce the behavior you describe when I use customize instead
of plain `add-hook' but I fail to see why your customizations are lost
with the first entry above.  My understanding is that your value should
be set just when loading latex.el after evaling the corresponding
defcustom form.  That would be ok.  AUCTeX itself just uses `add-hook'
and `remove-hook' on `LaTeX-mode-hook', so your configs should persist.

Anyone got a clue?

Ok, here are some workarounds:

  1. Use `add-hook' to add `flyspell-mode' and friends to
    `LaTeX-mode-hook'.

  2. Put (package-initialize) *before* the `custom-set-variables'
     section.  Then `LaTeX-mode-hook' is already defined when the
     `custom-set-variables' are applied which seems to fix the issue,
     too.

  3. Use a t NOW argument for customizing `LaTeX-mode-hook' as you've
     found out yourself.

Tassilo

If LaTeX-mode-hook is customized so that the customizations aren't
applied immediately, then the value of LaTeX-mode-hook is not set before
the line (add-hook 'LaTeX-mode-hook #'LaTeX-preview-setup) in
auctex-autoloads.el and after that call, regardless of the contents of
LaTeX-preview-setup, the customizations are not applied.  However, if I
comment out the line (add-hook 'LaTeX-mode-hook #'LaTeX-preview-setup)
inside auctex-autoloads.el then the value customizations are applied.

I should have mentioned that I'm running 24.5.1 with the same AUCTeX.

Exactly that's the case.

Yup.  I don't think that issue is actually related to all AUCTeX but it
works the way for all hooks with customization.  The only thing that
triggers the problem in AUCTeX is that AUCTeX itself adds a function to
the hook (and not as initial value).

I couldn't find any documentation that would define the interplay of
customize and hooks so I've asked for clarification on emacs-devel.

  https://lists.gnu.org/archive/html/emacs-devel/2015-08/msg00172.html

Until now, there are no answers but we'll see what the experts say.
IMHO, the current behavior is wrong.  Maybe a better approach was if
defcustoms of type hook wouldn't use `set-default' as :set function but
`add-hook'.  Then, hook customizations would have purely additive
semantics which sounds sensible to me.

It's the same with emacs 25 from the Git master's HEAD.

Hi Joseph,

I've just released GNU AUCTeX 11.88.7 on ELPA, and the problem should be
fixed now.  Please test and report back if if works now.

It may take up to 24 hours until the new version actually appears in the
package manager.

I've installed the latest version from git with your patch and get the
following when I open a tex file:

    (void-function LaTeX-preview-setup)

Recipe:

1)  Start emacs with
    emacs --eval '(setq debug-on-error t)' -Q &

2)  Eval in scratch buffer
    (load "auctex.el" nil t t)

3)  Open a tex file and emacs says:

--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (void-function LaTeX-preview-setup)
  LaTeX-preview-setup()
  TeX-latex-mode()

I can't reproduce the error with Emacs 24.5 and git AUCTeX.  Which
version of Emacs are you running?

Tassilo, the only point of your commit I don't understand is: what
happens when `declare-function' is not bound?

I'm running GNU Emacs 24.5 (64bit) on Win7.  I've just fetched the
entire repository and built AUCTeX again; the warning remains.

How can you do that without telling Emacs where auctex.el resides?

`LaTeX-preview-setup' is autoloaded from preview-latex.el.  So it relies
on

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

also being in your ~/.emacs.  Although I can omit that but still don't
get that error...

But I guess it wouldn't hurt to wrap the call in an fboundp check...

Which warning, and what about the error?

Anyway, I just guarded the call with an fboundp check so that you won't
get the error if you intentionally don't load preview-latex.

I was referring to the runtime behavior, but you replied me in another
message: `LaTeX-preview-setup' is an autoloaded function, so there
shouldn't be errors.

Sorry, my bad, yanked the wrong item.  I eval'ed:

    (load "~/.emacs.d/lisp/auctex.el" nil t t)

Thanks, I updated AUCTeX and the error (not warning) is gone.  I will
check this on my other box this weekend.  I wonder why this happened to
me while you and Mosè do not have this issue.

I'm curious too, thanks for looking into it.  I can reproduce your
error only if I load `auctex' but don't load `preview-latex' and then
run `TeX-LaTeX-mode', but opening a LaTeX files works flawless even
without loading `preview-latex' (and before Tassilo's last commit).

Could you please remove the "Mail-Followup-To: bug-auctex <at> gnu.org"
cookie from your emails?  This setting would open a new bug report for
everyone replying to you ;-)

Bye,
Mosè

I tried it again and also with a fresh compiled emacs 25.0.50 from
today.  But the issue remains.  I have no idea what's going wrong.  But
with the last patch from Tassilo it works smooth again.  So I think we
can close this one.

I read and post to this list through Gmane.  I think that cookie is
inserted by Gmane since I have no prerequisite to insert that in my
Gnus.  I will investigate if there is a way to avoid it.  Meanwhile, I
will try to reduce my contributions to this list to a minimum ;-) (I
have one bug report coming, though)

Best, Arash

FYI that won't happen so long as the subject starts with "Re: Bug#21188".
(As you can see from that fact several replies in this thread have gone
to "bug-auctex" already.)

However, M-F-T being set to _just_ the list will cause subsequent
replies to strip off anyone who had been cc'd in earlier discussion,
which is poor form since people shouldn't have to subscribe to bug lists
to take part.
