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,


I am getting the following error:

! LaTeX Error: Option clash for package hyperref.

When I try the following code,


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? Oct 6, 2012 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. Oct 7, 2012 at 3:54
  • @peter-grill: and the following errors: ! LaTeX Error: Command \maketitle already defined. ! LaTeX Error: Command \appendix already defined. Oct 7, 2012 at 3:56
  • @Ok, I did not have the lipics class so was not able to test it myself. Oct 7, 2012 at 4:07

You can use \hypersetup:


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:

\usepackage{lipsum}% just to generate text for the example
