Environment lstlisting undefined

Question

Hi I have installed the listings package in order to display my code. I am running the following code within my document:

\begin{lstlisting}
public static void main(String[] args) {
System.out.println("Hello World");
}
\end{lstlisting}

But that is giving me the following error:

! LaTeX Error: Environment lstlisting undefined.

I have mentioned \usepackage{listings} so I really dont know what the problem can be. Would anyone be kind enough to help or guide me the right way?

EDIT: Minimum working example:

\documentclass[a4paper,12pt]{book}

\usepackage{times,a4wide}
\usepackage{graphicx}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\usepackage{listings}

\begin{document}

\begin{lstlisting}
public static void main(String[] args) {
System.out.println("Hello World");
}
\end{lstlisting}

\end{document}

Can you take a look at this question? http://tex.stackexchange.com/questions/107534/how-often-do-i-have-to-synchronize-miktex — Mario S. E., Apr 30 '13 at 00:07
Welcome to TeX.sx! Please add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. — egreg, Apr 30 '13 at 00:07
@Matt9Atkins because I had a problem like that once, and even though I was loading the package with \usepackage I had to synchronize MiKTeX — Mario S. E., Apr 30 '13 at 00:09

@egreg MWE is added. I tried the MWE in a separate document and it work, just doesnt seem to work in my current document — M9A, Apr 30 '13 at 00:14
@Matt9Atkins then the package is installed... try running your present document with only the listings environment commented. check for any other errors — Mario S. E., Apr 30 '13 at 00:15
@MarioS.E. I algo get this error: LaTeX Warning: You have requested package listings', but the package provideslisting'. — M9A, Apr 30 '13 at 00:17
@Matt9Atkins FYI: Your MWE works fine... TeX Live 2012, Mac OS — , Apr 30 '13 at 00:18
It works fine in a new doc by just not in my current doc, any reasons why? — M9A, Apr 30 '13 at 00:19
Well, as an immediate workaround you could put your code inside a verbatim environment (\begin{verbatim} your code \end{verbatim}). However, there must be a reason why you are having this problem — Mario S. E., Apr 30 '13 at 00:27
having the exact same problem, looks like an "illegal" character (obtained by a copy-paste action) is the cause of the error message. I can't say more ;-) — PatrickT, Oct 15 '15 at 14:59

Based on the information you have given us, and due to the fact that your MWE runs OK in several of our systems (and even yours when pasted into a new document) I humbly conclude that there must be a typo somewhere in your original document.

As an immediate workaround, you could use the verbatim environment:

\begin{verbatim}
public static void main(String[] args) {
System.out.println("Hello World");
}
\end{verbatim}

But as mentioned before, this code runs perfectly on my system:

\documentclass{article}

\usepackage{listings}

\begin{document}

\begin{lstlisting}
public static void main(String[] args) {
System.out.println("Hello World");
}
\end{lstlisting}

\end{document}

ok so all you need is \usepackage{listings} - why not put that at the top of the answer? — Charlie Parker, Feb 23 '22 at 18:29
