Problem with listings-ext [closed]

Question

I am using listings-ext on Ubuntu 11.10 (with LyX) and listings.cfg defines the style colored-code - which I also use in the LaTeX preamble:

\usepackage[style=colored-code]{listings-ext}

But whenever I try to compile the document - into DVI or PDF I get this:

 \newcommand
                {\lstdef}[3]{%
The following styles weren't loadable:
    ,colored-code$
This may cause errors in the sequel.

And a message saying "Package Listings Error: style colored-code undefined".

How can I fix this?

This is what listings.cfg has:

\lstdefinestyle{colored-code}{
  backgroundcolor=\color{yellow!10},%
  basicstyle=\footnotesize\ttfamily,%
  identifierstyle=\color{black},%
  keywordstyle=\color{blue},%
  stringstyle=\color{teal},%
  commentstyle=\itshape\color{orange},%
}

Answer 1

I just tried:

\documentclass[a4paper, 11pt]{article}

\usepackage[style=colored-code]{listings-ext}

\begin{document}
test
\end{document}

with the example listings.cfg:

\ProvidesFile{listings.cfg}%
  [2009/08/23 v1.0 listings configuration of listings-ext]

\RequirePackage{xcolor}

\def\lstlanguagefiles{lstlang1.sty,lstlang2.sty,lstlang3.sty}
\lstset{defaultdialect=[ANSI]C,
        defaultdialect=[ISO]C++,
        defaultdialect=[95]Fortran,
        defaultdialect=Java,
        defaultdialect=[LaTeX]TeX,
        frame=tlb,
        resetmargins=false,
        }
\lstdefinestyle{colored-code}{
  backgroundcolor=\color{yellow!10},%
  basicstyle=\footnotesize\ttfamily,%
  identifierstyle=\color{black},%
  keywordstyle=\color{blue},%
  stringstyle=\color{teal},%
  commentstyle=\itshape\color{orange},%
}
\lstdefinestyle{bw-code}{
  basicstyle=\small\fontfamily{lmtt}\fontseries{m}\fontshape{n}\selectfont,
  % instead of lmtt one should use ul9 (luximono) for boldface characters
  keywordstyle=\small\fontfamily{lmtt}\fontseries{b}\fontshape{n}\selectfont,
  commentstyle=\small\fontfamily{lmtt}\fontseries{m}\fontshape{sl}\selectfont,
  stringstyle

=\small\fontfamily{lmtt}\fontseries{m}\fontshape{it}\selectfont,
}

and it is all compiling without errors. I think your listings.cfg is wrong.
