Re: Extending ODT export

[Jambunathan K <kjambunathan@gmail.com>]

doc-view (for OpenDocument files) uses the below mentioned work around.

The fix can be ported to `org-odt.el' and `ox-odt.el'.

(defun doc-view-odf->pdf-converter-soffice (odf callback)
  "Convert ODF to PDF asynchronously and call CALLBACK when finished.
The converted PDF is put into the current cache directory, and it
is named like ODF with the extension turned to pdf."
  ;; FIXME: soffice doesn't work when there's another running
  ;; LibreOffice instance, in which case it returns success without
  ;; actually doing anything.  See LibreOffice bug
  ;; https://bugs.freedesktop.org/show_bug.cgi?id=37531.  A workaround
  ;; is to start soffice with a separate UserInstallation directory.
  (let ((tmp-user-install-dir (make-temp-file "libreoffice-docview" t)))

			     (concat "-env:UserInstallation=file://"
				     tmp-user-install-dir)
