Hi,
I am trying to use the packages algorithm and hyperref together. Depending
on the order in which the packages are loaded, this does or doesn't work.
The order that works however, is impossible to set using LyX. Consider the
following latex source:
========================= test.tex =========================
\documentclass{article}
\usepackage{algorithm}
\usepackage{algorithmic}
\usepackage{hyperref}
\begin{document}
\tableofcontents
\pagebreak
\section{First section}
\label{firstlabel}
\pagebreak
\section{Second section}
\label{secondlabel}
\pagebreak
\begin{algorithm}
\begin{algorithmic}
\STATE x $\leftarrow$ 1
\end{algorithmic}
\caption{The caption for the algorithm}
\label{algorithmlabel}
\end{algorithm}
\pagebreak
See Algorithm \ref{algorithmlabel} to understand Section \ref{firstlabel}.
\end{document}
========================= test.tex =========================
This produces the following output (actually on the second run, when the
.aux file is generated):
========================= output =========================

The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

========================= output =========================
If it put "\usepackage{hyperref}" before "\usepackage{algorithm}" the
problem is solved. However, the only way to include hyperref in LyX
1.6.1fix1 is to include it in the preamble, where it appears after the
packages LyX includes. Does anyone know a good workaround for this problem?
