I recently noticed that the auctex style files were not being loaded.
Following some investigation, I've discovered the cause, and thought I would
relate the story.
With a bit of fiddling, I tracked the problem down to TeX-data-directory,
which is my case is set wrong, specifically to
~/emacs/packages/auctex-11.58/auctex
Notice the extra "auctex". Hence the style files were not being found.
I traced this back to
(defvar TeX-lisp-directoryr
(expand-file-name "auctex" (file-name-directory load-file-name))
"The directory where most of the AUCTeX lisp files are located.
For the location of lisp files associated with
styles, see the variables TeX-style-* (hand-generated lisp) and
TeX-auto-* (automatically generated lisp).")
where the problem is evident.
I normally install auctex by unpacking the tar ball in ~/emacs/packages
(creating auctex-x.x where x is the version number), and doing ./configure,
make, but no make install. This is how I install most packages and it works
well for me; I just add all directories in ~/emacs/packages to the path
recursively.
So, I figure, auctex must use one directory structure for packaging (where no
auctex directory exists) and another for installation (where it does).
So I decided to try the make install option instead. So I move auctex away
from ~/emacs/packages, and try
./configure --prefix=/home/username/emacs/packages/auctex
which is nearly what was suggested in "Installation for non-privelleged
users". But this appears to be ignored -- make install tries to isntall in
/usr/share...
Anyway, I was left feeling a little confused. Could I suggest the following?
(defvar TeX-data-directory
(let ((installed (expand-file-name "auctex" (file-name-directory
load-file-name)))
(local (expand-file-name (file-name-directory load-file-name))))
(cond
((file-readable-p installed)
installed)
((file-readable-p local)
local
(t
(error "Unable to find TeX-data-directory"))))))
Failing this, even the addition of an error message would be good. It took me
quite a while to track this down because the cause of the problem is quite a
way from where it becomes apparent (that is, style files don't work).
Thanks
Phil
