Re: Opendocument export causes error

[Torsten Anders <torsten.anders@beds.ac.uk>]

Dear Jambunathan and others,

Apologies for resending this message, but my email from yesterday seemingly did not arrive.

To summarise at first, the results in my 2nd IELM session (at the end of the message below) differed clearly from those in your kindly provided template -- in several cases symbol-file returned nil instead a path, and for (symbol-file 'org-macs 'require) it returns a different path that in your template. Does that perhaps point towards the problem? 

Here is the full story. Please remember that I cannot not use the OpenDocument export, because -- as far as I understood -- (the correct version of) "org-compat.el" and "org-odt.el" are not loaded. This is perhaps caused by the fact that the Emacs I am using (the latest stable release of Aquamacs, version 2.4) is based on the rather old GNU Emacs 23.3.50.1. Aquamacs is widely used on the Mac platform, so likely I am not the only one with these problems. 

I temporarily fixed my problem by loading the respective libraries manually in my ~/.emacs file as below, but as others may also have this problem this is probably not the best and certainly not a clean solution.

(load-library "org-compat.el")
(load-library "org-odt.el")


Anyway, I finally ran the tests you suggested (thanks a lot for detailing these!).

Aquamacs started. Clearly, Aquamacs was not fully loaded (e.g., standard Mac short-cuts where not yet defined). Anyway, it output the following message in *Messages*

To double check, I confirmed the Emacs version.

nil


I restarted Aquamacs and repeated all above except for the previous ielm session (just in case, as I do not know whether symbol-file has any side effects).

Again, thanks a lot for your help!
