Hi
I have the attached org file.
It seems that when exporting to a pdf, the :session argument is ignored, as
I get a
Org-Babel Error Output buffer with:
Error: object 'x' not found
Execution halted
and an Org-Babel Error buffer with the same text, and the resulting pdf does
only show the code..
HTML export, works as expected.
If I put :session *R_test* behind #+begin_src (R2.org) it works.
Cheers,
Rainer

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

That workaround looks really good - thanks. Much better then putting
:session at the beginning of each source block.

Would it be possible to issue a warning if a #+BABEL line is stripped by
LaTeX? If I think back, this stripping cost me quite some time to figure out
why things are working differently when exporting to LaTeX then html.

No, we really need to fix this.
Can someone please try if the following patch does fix this issue?

Hi Carsten,
I've just tested your patch against the following minimal example, and
it does fix the problem, in that both of the R blocks now use the
session from the #+BABEL: header.
--8<---------------cut here---------------start------------->8---
#+Title: testing preservation of babel header
#+Author: Eric
#+BABEL: :session *R*
* top header
#+begin_src R :exports code
x <- 1
#+end_src
The result from the above block + 1 should be src_R{x+1}.
--8<---------------cut here---------------end--------------->8---
Additionally I tested it against the in example which my previous patch
was causing errors, namely
--8<---------------cut here---------------start------------->8---
#+OPTIONS: skip:nil
text before first
* Test
\begin{equation}
E=mc^2
\end{equation}
--8<---------------cut here---------------end--------------->8---
and this exported without problem. So it looks to me like this patch
should be applied.
Thanks for implementing a solution here.
Best -- Eric
