bug#24866: AucTeX not working on Emacs 25.1.1 for Mac

[Lars Eriksson]

Hi Mosè,

I have now tested AucTeX (from git) on Emacs 25.1-1 on Mac and I am sorry to 
say that adding load paths did not help in my case. Same error, independent of 
load path. I have tried both without and with the addition of one and both of 
the following load paths before loading auctex.el
(add-to-list 'load-path "/Applications/Emacs.app/Contents/Resources/site-lisp")
(add-to-list 'load-path 
"/Applications/Emacs.app/Contents/Resources/site-lisp/auctex")
(load "auctex.el" nil t t)

From the debugger output below I have found that the error is encountered when 
it evaluates TeX-latex-mode() in the file latex.el. Even without the load paths 
above Emacs finds the file latex.el file that resides in the directory:
/Applications/Emacs.app/Contents/Resources/site-lisp/auctex/

My debugging skills and emacs hacking skills are limited so I have only run the 
lisp code to start the debugger (setq debug-on-error t). Then I load a latex 
file ”test.tex" and get the following backtrace:

Debugger entered--Lisp error: (void-variable LaTeX-preview-setup)
  byte-code("\303\300\304\"\210\305\306!\203\306\307

  find-file("~/Src/test.tex" t)
  funcall-interactively(find-file "~/Src/test.tex" t)
  call-interactively(find-file nil nil)
  command-execute(find-file)

Tests with Emacs 25.1-1 show that auctex-11.88 works  but neither auctex-11.89 
nor the recent git version, this is on a Mac running El Capitan 10.11.6.

With Em25.5-1 and Auc11.88 I have a working configuration that I am satisfied 
with.
I really appreciate what Emacs and AucTeX helps me do in my writing, thanks for 
all your excellent work and efforts!

This is reported to help you in the development process.

Kind regards,
Lars Eriksson
