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

[Lars Eriksson]

Dear Mosè,

Thank you for caring about this, and pointing me to git bisect. Sorry for taking so long time to respond but I had to make a business trip to China and did not have access to this computer for testing. I am now back and I have now run a git bisect (for the first time in my life) and received the following, results.

I have not analyzed what the difference is between the versions but it its clear that it touches the preview… I do not know why it causes the error on Mac...

Best,

Lars

    Setup preview differently; fixes bug#21188

    

    * latex.el (TeX-latex-mode): Call `LaTeX-preview-setup'

    unconditionally instead of calling it from `LaTeX-mode-hook' which

    breaks things if that hook is customized (bug#21188).

    

    * preview.el.in: Don't add `LaTeX-preview-setup' to

    `LaTeX-mode-hook'.

Hi Lars,

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.

That's no surprise, since it's the only place where the function is
called ;-)  The point is that the function should be called only if
it's available, but when it's called it turns out that it's not
actually there.

If you're familiar with git, can you please run git bisect in order to
look for the offending revision?  You can use "release_11_88" as good
revision, and "release_11_89" as the bad one.

Thanks,
Mosè
