I'm using orgmode version 7.8.06. Right now, whenever an org file is
exported to LaTeX, each heading is assigned an automatic label (e.g.
sec-1). All hyperlinks to the heading will also use this label.
There is a standard orgmode property for assigning custom ID to
headings for hyperlinks: CUSTOM_ID. Exporting a heading with
CUSTOM_ID produces two labels, one automatic label by the LaTeX
exporter and one by CUSTOM_ID. However all hyperlinks to the heading
use the automatic label. For example, the following org code:
======== BEGIN =========
* Section 1
:PROPERTIES:
:CUSTOM_ID: sec:section-1
:END:
This is section 1.
* Section 2
Refer [[Section 1]].
======== END ===========
produces LaTeX code:
======== BEGIN =========
\section{Section 1}
\label{sec-1}
\label{sec:section-1}
This is section 1.
\section{Section 2}
\label{sec-2}
Refer \hyperref[sec-1]{Section 1}.
======== END ===========
Although this is not a bug, I think the LaTeX exporter should honor
the CUSTOM_ID property, and only assign an automatic label in the
absent of this property. The above LaTeX should read:
======== BEGIN =========
\section{Section 1}
\label{sec:section-1}
This is section 1.
\section{Section 2}
\label{sec-2}
Refer \hyperref[sec:section-1]{Section 1}.
======== END ===========
If the hyperlink is changed to using the CUSTOM_ID instead of the
heading text, it produces wrong LaTeX code:
\hyperref[sec-section-1]{\#sec:section-1}. This is definitely a bug.
