# Incompatibility between lipics and hyperref

I am using the lipics document class. I want to use the hyperref package with this and pass some parameters to it. When I use this code,

\documentclass[a4paper,UKenglish]{lipics}
\usepackage[pdftex,bookmarks=false,pdfstartpage=5]{hyperref}


I am getting the following error:

! LaTeX Error: Option clash for package hyperref.


When I try the following code,

\documentclass[a4paper,UKenglish,hyperref={bookmarks=false,pdfstartpage=5}]{lipics}


I am getting 469 errors and the first one is:

! LaTeX Error: Missing \begin{document}.


What is the right way to combine lipics and hyperref?

Welcome to TeX.SE. You could try \RequirePacakge[pdftex,bookmarks=false,pdfstartpage=5]{hyperref} before \documentclass? –  Peter Grill Oct 6 '12 at 15:27
@peter-grill: The code you mentioned, gives the following warning: Package hyperref Warning: Option 'pdfpagelabels' is turned off (hyperref) because \thepage is undefined. –  Arindam Pal Oct 7 '12 at 3:54
@peter-grill: and the following errors: ! LaTeX Error: Command \maketitle already defined. ! LaTeX Error: Command \appendix already defined. –  Arindam Pal Oct 7 '12 at 3:56
@Ok, I did not have the lipics class so was not able to test it myself. –  Peter Grill Oct 7 '12 at 4:07

You can use \hypersetup:

\documentclass[a4paper,UKenglish]{lipics}
\hypersetup{bookmarks=false,pdfstartpage=5}
\begin{document}
test
\end{document}


This suppresses the errors, but still leaves a warning:

Package hyperref Warning: Option bookmarks' has already been used, setting the option has no effect on input line 2


To suppress the bookmarks, you can use the bookmark package and its depth option:

\documentclass[a4paper,UKenglish]{lipics}
\hypersetup{pdfstartpage=5}
\usepackage[depth=0]{bookmark}
\usepackage{lipsum}% just to generate text for the example
\begin{document}
\section{test}
\lipsum[1-90]
\end{document}

This works fine. Thank you very much! –  Arindam Pal Oct 7 '12 at 4:00
