I've been having a problem exporting to beamer. I've now found the
problem and fixed it, but it was (to my mind) something pretty
obscure, and I think it might be of interest to the list, at least
as a salutary tale.
When I opened an org file such as the example beamer presentation
from the manual (section 12.6.6) and executed C-c C-e d, it kept
generating a .tex file with an article document class, instead of
the expected beamer class.
After a few days of frustrated searching through the manual and
tutorials, and this list, for any clues, I found some advice to run
something like
/usr/bin/emacs -Q -l test.el
with a series of versions of test.el progressively approximating
my .emacs file. I was expecting the problem to lie in one of my org-
or latex-specific settings, but eventually found the cause of the
problem to be that the variable
case-fold-search
was being set to nil (its default value) as one of my custom-set-
variables. I don't remember why. Anyway, according to the
information from C-h v, this makes the setting buffer-local, and for
some reason that fouled up the beamer export. When I commented out
that line, everything worked as advertised.
I'd be interested to hear from anyone who could shed light on why
that might be.
Well,
apparently Org does do a search that relies on case-fold-search
being t. Normally when this is the case
I try to set this explicitly to t during the function call.
Can you make a minimal example with your setup and a small file which
reproduced the error?
