Re: [Orgmode] [BABEL] Bugin :session? Export html - works --- export pdf not

[Eric Schulte]

Hi Rainer,

I am aware of this problem, and although I don't know any a good
solution, I do have a good workaround (example attached [1]).

The problem is that org-latex removes all of the #+ lines from the
beginning of any Org-mode file which has headlines as part of the export
process.  This means that by the time it's Babel's turn to run code
blocks, the #+BABEL line has been removed, and the session is not set.
If there are no headlines, then this problem does not arise.

I sent in a patch last week, [2] but it's application would have broken
other features of the latex export, I've yet to work out a good solution
to this.

There is a decent work-around.  Whenever there are no headlines, then
the #+BABEL: line works fine on LaTeX export, when there are headlines,
then header arguments can be placed as properties in the headlines to
the same effect.

Cheers -- Eric
