Dear all,

I am using emacs with this configuration file:

#+BEGIN_SRC emacs-lisp
(setq load-path (append (file-expand-wildcards "~/.emacs.d/elpa/*") load-path))
(require 'org)
(require 'org-ref)
(require 'ox-extra)
(ox-extras-activate '(ignore-headlines))
(defun remove-orgmode-latex-labels ()
   "Remove labels generated by org-mode"
   (interactive)
   (let ((case-fold-search nil))
    (goto-char 1)
    (replace-regexp "\\\\label{sec.*}" "")
    )
)
(add-hook 'org-export-latex-final-hook 'remove-orgmode-latex-labels)
#+END_SRC

to load the latest orgmode from melpa and install a hook to remove 
unwanted section labels on latex export.

If you open/create any .org file and export it to latex buffer or file, 
the hook function is not called. if I visit the buffer and call 
remove-orgmode-latex-labels, section labels are removed.

Where is the mistake?

Thanks,

Giacomo
