Hello,
I run into a problem with AUCTeX and recent Emacs.
I prepared small LaTeX document and run Emacs
emacs -Q --debug-init --eval '(setq load-path (cons "/usr/share/emacs/site-lisp" load-path))' -l /usr/share/emacs/site-lisp/auctex.el ex.ltx
After start in window at bottom message is shown:
Error: Don't know how to compile nil
The name of window is `*Compile-Log*'.
I suspect that problem with `byte-compile' changed in rev. 108778 which
is used in `font-latex.el' file, part of AUCTeX package.
Sorry, I can't make more minimal example, so I don't know the actual
reason of the problem.
In GNU Emacs 24.1.50.1 (x86_64-unknown-linux-gnu, GTK+ Version 3.4.3)

Can you please try: emacs -Q --debug-init --eval '(setq load-path (cons "/usr/share/emacs/site-lisp" load-path) debug-on-error t byte-compile-debug t)' -l /usr/share/emacs/site-lisp/auctex.el ex.ltx
and show us the resulting backtrace (assuming you get one)?

For me, the error comes from the stuff at the very end of font-latex.el:
http://cvs.savannah.gnu.org/viewvc/auctex/font-latex.el?root=auctex&view=markup
;;; Byte-compilation of generated functions
(when (byte-code-function-p
(symbol-function 'font-latex-make-built-in-keywords))
(dolist (elt font-latex-built-in-keyword-classes)
(let ((name (nth 0 elt)))
(byte-compile (intern (concat "font-latex-" name)))
(byte-compile (intern (concat "font-latex-" name "-make"))))))
->
Error: Don't know how to compile nil in font-latex-warning
Error: Don't know how to compile nil in font-latex-warning-make
etc
"font-latex-warning" etc is not defined.
font-latex-make-built-in-keywords actually defines things with a
"font-latex-match-" prefix, not "font-latex-".
In 24.1
(byte-compile nil)
silently does nothing
in trunk it complains:
Error: Don't know how to compile nil
So this looks like a long-standing font-latex bug that Emacs isn't
silent about any more.

Yes, I got. I run above command, copied (`C-x r s r') to other buffer
(`C-x r i r') and saved as file `backtrace.txt'. I hope this is the
right way.

Good catch. I've fixed that in AUCTeX CVS. I think, it's time for a
new AUCTeX release. 11.86 is already 4 years old...

It hasn't shown up in
http://cvs.savannah.gnu.org/viewvc/auctex/auctex/font-latex.el?view=log
for me yet, so I don't know what change you made, but you could probably
just remove the associated code entirely, since it seems no one ever
noticed it was doing nothing, so this can't be an area that is
noticeably slow and in need of byte-compilation tricks.

Then you could fix http://debbugs.gnu.org/10584 :)
Isn't it "only" 2 years though?

I just corrected the prefix. My very subjective feeling is that
initially opening a very large latex file is a bit faster now.

That would be fixed automatically. I'll ask on the auctex-devel list if
it's the right time for a new release.

Yes, when viewing the info of the ELPA package, there's only a 2008
copyright header so I guessed the latest release was in 2008.

Summary:
This is a long-standing font-latex.el bug, it just happens that Emacs is
no longer silently ignoring it. Updating your font-latex will make it go
away.
