"No definition for class" error in export to latex

"No definition for class" error in export to latex

[Levy, Roger]

Hi,

I am an org-mode newbie and trying to learn how to export to latex and html from the command line, and have encountered a difficulty when I include a custom class in the latex header.  Here's a sample file ("test-file.org") I'm using:

***

#+TITLE: Test
#+LaTeX_CLASS: apa

file contents

***

and here is the command I'm using:

/Applications/Aquamacs.app/Contents/MacOS/Aquamacs -batch \
    --visit=test-file.org \
    --funcall org-export-as-latex-batch

which gives me the output

OVERVIEW
Exporting to LaTeX...
No definition for class `apa' in `org-export-latex-classes'

and no .tex file output.  From within Aquamacs, I don't get this error, presumably because I have the following in my .emacs file:

(add-to-list 'org-export-latex-classes
	     '("apa"
	       "\\documentclass{apa}
               [NO-DEFAULT-PACKAGES]
               \\usepackage{graphicx}
               \\usepackage{apacite}"
	       ("\\section{%s}" . "\\section*{%s}")
	       ("\\subsection{%s}" . "\\subsection*{%s}")
	       ("\\subsubsection{%s}" . "\\subsubsection*{%s}")
))

How can I make this modification of org-export-latex-classes from the command line?  I have tried putting the above content in a file ("$HOME/tmp/add.el") and making the call

/Applications/Aquamacs.app/Contents/MacOS/Aquamacs -batch \
    --load $HOME/tmp/add.el \
    --visit=test-file.org \
    --funcall org-export-as-latex-batch

but this gives me the error

  Symbol's value as variable is void: org-export-latex-classes

I would be very grateful for any suggestions!  This is GNU Emacs 23.3.1 (Aquamacs 2.2) and Org mode 7.5.

Incidentally, trying to export to HTML with

/Applications/Aquamacs.app/Contents/MacOS/Aquamacs -batch \
    --visit=test-file.org \
    --funcall org-export-as-html-batch

complains differently: 

OVERVIEW
Exporting...
File mode specification error: (file-error "Cannot open load file" "html-helper-mode")
Exporting...
Exporting...
File mode specification error: (file-error "Cannot open load file" "html-helper-mode")
Saving file /tmp/test-file.html...
Wrote /tmp/test-file.html
HTML export done, pushed to kill ring and clipboard

but it actually does produce a sensible html file.

Many thanks in advance for patience with my newbie question.

You should add to add.el some more initialization: you probably need to
set the load-path and require the org-latex package - something like
this, but you should more or less mimic the way you initialize org mode
in your .emacs:

--8<---------------cut here---------------start------------->8---
(add-to-list 'load-path (expand-file-name "~/src/emacs/org/org-mode/lisp")) ;maybe
(add-to-list 'auto-mode-alist '("\\.\\(org\\|org_archive\\|txt\\)$" . org-mode))
(require 'org-install) ; maybe

(require 'org-latex)
...apa stuff from above...
--8<---------------cut here---------------end--------------->8---

Remember: -batch implies -q so your .emacs file is completely ignored:
you have to do any initialization you need in the add.el file.

I don't know who tries to load html-helper-mode but that's not even
present in my setup.

Probably because the autoload for org-export-as-html-batch is
in the default path of your emacs.

Many thanks, Nick.  I have managed to get things to work with the following add.el file contents:

--8<---------------cut here---------------start------------->8---
(setq load-path (cons "/Users/rlevy/tmp/org-7.5/contrib/lisp" load-path))
(setq load-path (cons "/Users/rlevy/tmp/org-7.5/lisp" load-path))
(require 'org-install)
(require 'org-latex)
(require 'org-exp-bibtex)
(add-to-list 'auto-mode-alist '("\\.org\\'" . org-mode))
(add-to-list 'org-export-latex-classes
	     '("apa"
	       "\\documentclass{apa}
               [NO-DEFAULT-PACKAGES]
               \\usepackage{graphicx}
               \\usepackage{apacite}"
	       ("\\section{%s}" . "\\section*{%s}")
	       ("\\subsection{%s}" . "\\subsection*{%s}")
	       ("\\subsubsection{%s}" . "\\subsubsection*{%s}")
))
--8<---------------cut here---------------start------------->8---

Probably some of that may be unnecessary too, but (require 'org-latex) was definitely needed.

OK -- I will not worry about this for now.

Thanks again.

I don't use this version of Emacs (not on a Mac) so cannot guarantee
anything I say will be relevant... but have you tried adding

   (require 'org-latex)

before you set the org-export-latex-classes variable?  I'm assuming that
org mode is actually already loaded by default.

HTH.
