General ⇒ cleveref | Multiple References in Appendix

[craq]

Hi,
I use the cleveref package to reference more than one equation simultaneously, like multicite. But it doesn't work in the appendix. I get the error
"A number should have been here; I inserted `0'." in the log file or
"Missing number, treated as zero. I use \cref{eqn:3,eqn:4}" in the kile output. This minimum working example should show what I mean:

Code: Select all

\documentclass[a4paper,10pt]{report}
\usepackage{cleveref}
\begin{document}
\chapter{sec1}
\begin{equation}
 1+1=2\label{eqn:1}
\end{equation}
\begin{equation}
 1+1=2\label{eqn:2}
\end{equation}
I use \cref{eqn:1,eqn:2}

\appendix
\chapter{app1}
\begin{equation}
 1+1=2\label{eqn:3}
\end{equation}
\begin{equation}
 1+1=2\label{eqn:4}
\end{equation}
I use \cref{eqn:3,eqn:4}
\end{document}

Does anybody know how to make it work? Is it a bug in cleveref?

No problem here. Perhaps a matter of an outdated package. Add the \listfiles command as very first line to your example and take a look at the list of used files in the log file. Compare with mine.

Code: Select all

 *File List*
  report.cls    2007/10/19 v1.4h Standard LaTeX document class
  size10.clo    2007/10/19 v1.4h Standard LaTeX file (size option)
cleveref.sty    2011/03/22 v0.17.9 Intelligent cross-referencing
 ***********

Get an update as the case may be.

P.S.: Very good example.

You were right, thanks! I had cleveref.sty from 2009, which is in the current version of texlive in the ubuntu repositories. It was a bit of a challenge to install the new texlive manually, so I'll write out what I did here. (At least I'll be able to find it next time.) The main problem was disk space, texlive 2011 is 3GB!

1. Check free disk space on the root (or /usr) partition
2. Download latest texlive and run install.tl
3. edit /etc/texmf/texmf.d/05TeXMF.cnf so that the path where texlive is installed appears on the "main distribution tree". Specifically, change
   TEXMFDIST = /usr/share/texmf-texlive
   to
   TEXMFDIST = /usr/local/texlive/2011/;/usr/share/texmf-texlive
4. sudo update-texmf && sudo texhash && sudo mktexlsr
