I may be doing something wrong but can't realize what...

I want to set a label for a piece of code represented by:

\lstinputlisting[language=Python, label={lst:control_os_call}, firstline=231, lastline=257]{./code/server.py}

so, I just try to link it using \ref

\ref{lst:control_os_call}

but I am getting a label missing error all the time (just for labels on \lstinputlisting). So... Should I import any specific package to reference those kind of labels or what am I doing wrong?

Thanks a lot :)

You need to add a caption thats all

\documentclass{article}
\usepackage{filecontents}
\begin{filecontents*}{server.py}
This is some python code
\end{filecontents*}

\usepackage{listings}
\lstset{basicstyle=\ttfamily}

\begin{document}
\lstinputlisting[language=Python,caption={some python code}, label={lst:control_os_call}, firstline=1, lastline=257]{server.py}

Here is the code~\ref{lst:control_os_call}
\end{document}
