# error with hyperref and the krantz class [closed]

I'm using the krantz.cls to write a book, and I ran into an error with the hyperref package. Here is a minimal example (test.tex):

\documentclass{krantz}
\usepackage{hyperref}
\begin{document}
\chapter{Introduction}
\end{document}


When I compile it with pdflatex test.tex, I get this error:

Runaway argument?
{Introduction}]{[}{Introduction}]{Introduction} \end {document}
! File ended while scanning use of \Hy@org@chapter.
<inserted text>
\par
<*> test.tex


Without hyperref, it compiles fine. I appreciate if anyone can tell me why this happens and how to fix it.

## Update

I contacted the author of this package and the problem was solved. See the corrected krantz.cls.

I figured out that the recent versions of the krantz class do not work with the latest version of hyperref. I systematically tried versions from:

The crash occurs at starting at version

File: hyperref-6.83b.tds.zip 3925 KB 18/08/2012 12:00:00 AM

and higher (crashes with 6.83c, 6.83f, 6.83k, 6.83m) and will compile with the earlier version

File: hyperref-6.83a.tds.zip 3915 KB 13/08/2012 12:00:00 AM

The older version 6.83a has lines like:

\hyper@linkstart{link}{#4}{#2}\hyper@linkend


and has been replaced in the newer version 6.83b with

\hyper@linkstart{link}{\Hy@tocdestname}{#2}\hyper@linkend


The error that is generated when compiling with 6.83b is

! Undefined control sequence.
<argument> \Hy@tocdestname

l.6 \tableofcontents

?


My guess is that is the region causing the errors.

So the work around is to use hyperref version 6.83a.

Seems to be an error in the class; contact the author. – Martin Schröder Dec 8 '12 at 13:37
Despite the class' claim - this is not a standard LaTeX class. In particular its internal command \@chapter used for chapters has a non-standard argument format, which hyperref therefore does not recognise. – Andrew Swann Dec 8 '12 at 18:08
@AndrewSwann Thanks a lot! That \@chapter is exactly what I want to know; at least I know the direction to fix it now. – Yihui Dec 8 '12 at 18:11
