PSTricks error "Undefined control sequence \c@lor@to@ps"

Question

I have a problem with this file tex:

\begin{document}
\begin{figure}
\begin{center}
\begin{pspicture}(0,0)(1,3.8)
\psline{-<}(0,0)(0,.2)
\psline{-}(0,.2)(0,.4)
\psline{*->}(0,.4)(0,.9)
\psline{-*}(0,.9)(0,1.4)
\psline{-<}(0,1.4)(0,2.4)
\psline{-}(0,2.4)(0,3.4)
\psline{*-}(0,3.4)(0,3.6)
\psline{>-}(0,3.6)(0,3.8)
\rput(1,.4){$y=0$}%testo
\rput(1,1.4){$y=1$}
\rput(1,3.4){$y=3$}
\end{pspicture}
\end{center}
\caption{}
\end{figure}
\end{document}

but I don't understand where is the error.

Welcome to TeX.sx! A tip: If you indent lines by 4 spaces, they'll be marked as a code sample. You can also highlight the code and click the "code" button (with "{}" on it). I think we will need a full minimal working example (MWE) including your preamble. — Joseph Wright, Aug 26 '12 at 15:54
It is not related to your problem but it is worth mentioning that it is recommended to use \centering instead of \begin{center}...\end{center}. — kiss my armpit, Aug 26 '12 at 16:00

It was the typical error message when using pdflatex with PSTricks. With an up-to-date version you'll get an error message which explains what's the problem.

Run the document with xelatex or use the sequence latex->dvips->ps2pdf (which is often only one click in a GUI). See also FDE no 4 (Frequently Done Error) at http://PSTricks.tug.org

This worked for me. Wish I could get the tick beneath the answer :-P but only if it works for the asker! – Karthik C Oct 02 '13 at 04:59
Just click the grey tick mark beneath the score on the answer you want to accept. The tick mark will turn green. That means the answer is accepted and everyone will know that the problem has been solved. – Karthik C Oct 03 '13 at 06:30

There is another solution : you can use pdfLaTeX with pstricks, provided pdflatex is launched with one of these switches: --enable-write18 (MiKTeX) or --shell-escape (TeXLive, MacTeX), and you load the auto-pst-pdf package after pstricks.

Note that if you try to load xcolor with an option, there is an option clash for package 'xcolor' error message because pstricks already loads xcolor (without option). A work-around consists in adding the xcolor option to the document class options, or writing PassOptionsToPackage{option}{xcolor}.

As an example you may begin your document with something like:

\usepackage[11pt, a4paper, twoside, x11names, table]{article}

\usepackage{pst-plot}
\usepackage{auto-pst-pdf}
