\documentclass{scrbook}
\usepackage{listings}
\usepackage{cleveref}
\begin{document}
Ref: \ref{test}.
Cref: \cref{test}.
\begin{lstlisting}[caption={Test},label={test}]
test
\end{lstlisting}
\end{document}
This produces Ref: 1. Cref: ?? 1.. I expected something like Ref: 1. Cref: Listing 1.
I get a LaTeX Warning: \Cref reference format for label type 'lstlisting' undefined on input line 9.
Solution 1
Add the following to your header:
\crefname{lstlisting}{listing}{listings}
\Crefname{lstlisting}{Listing}{Listings}
Solution 2
Download the newest version from here (cleveref.dtx and cleveref.ins) and run latex cleveref.ins.
LaTeX Warning: \Cref reference format for label type 'lstlisting' undefined on input line 9.. Seriously, my cleveref version was to old :).
tlmgr info cleveref tells I run 0.19 2014-02-26 which I assume is even newer. Still, I ran latex several times, and it would not detect the listing as a listing. Had to go with solution 1 :(
\Crefname is superfluous in the above case. As mentioned in section 8.1.2 of the cleveref documentation, "If the corresponding \Crefname is undefined when \crefname is called, it will automatically define \Crefname to be a capitalised version of \crefname, using \MakeUppercase."
listings is included BEFORE cleveref!
