links to headline in LaTeX export

links to headline in LaTeX export

[Alan Schmitt]

Hello,

I'm trying to have links (in the form of \ref and \label) work in LaTeX 
export, but I cannot seem to succeed. I'm following the advice of 
http://orgmode.org/worg/org-tutorials/org-latex-export.html (section 
16). I have two problems with my links: first I would like the text to 
be the section number as is the usual in LaTeX, and second the links 
sometimes point to the wrong place. This second problem seems to occur 
when the target is after the source.

Here is a small input showing the problem:

* Title

** Section 1

Text.

** Section 2

I would like a link to [[Section%201][Section 1]] or [[Section 3]].

** Section 3

I would like a link to [[Section%202][Section 2]].



Exporting to LaTeX gives:

I would like a link to \hyperref[sec-1.2]{Section 2}.

Any suggestion?

Thanks,

Alan

You could always do this directly using label and ref explicitly?  See
attached org document.  This may not be the ideal solution but at least
it works and is fairly unobtrusive...

HTH,

Thanks a lot. It works great and solves both issues. It's not as pretty 
as a real link, but it will clearly do until I understand better how 
LaTeX export works.

Aloha Alan,

Your LaTeX output indicates that this setting:

(setq org-export-latex-hyperref-format "\\ref{%s}")

hasn't taken effect for one reason or another.

What do you get with C-h v org-export-latex-hyperref-format RET?

All the best,
Tom

I get what I would expect:
org-export-latex-hyperref-format's value is "\\ref{%s}"

For some reason it is not taken into account, and I'll have to 
investigate why. I'm exporting doing "C-c @" to choose the sub-tree to 
export, then "C-c C-e l" to get the LaTeX.

Aloha Alan,

Hmmm, I can't reproduce your results on my setup.  What version of Org
mode are you using?

All the best,
Tom

I'm using the one bundled with Aquamacs 2.4, which is 6.33x. Looking at 
the web site, I see that it's quite outdated. I'll try to update it this 
week-end and see if it fixes things.

Thanks a lot for your help,

Alan

I installed the current version from git, and everything work as 
expected. Sorry for the noise, and thank for the help.

Glad to hear that you are up and running.  Welcome to the Org mode
community!

Regarding your interest in the LaTeX exporter, please be aware that an
experimental exporter is under development by Nicolas Goaziou.  One of
the design goals is to iron out differences in translations to different
targets (HTML, LaTeX, etc.).  I expect that this will make its way
steadily toward the Org mode core and that it will, in some cases,
change the current LaTeX export behavior.

All the best,
Tom
