# epspdfconversion isn't working

I'm with a problem with the package epspdfconversion. I use the following preamble:

\documentclass[pdftex,12pt,a4paper,openany]{memoir}
\usepackage[brazil]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{indentfirst}
\usepackage{latexsym}
\usepackage{amsmath,amssymb,amsfonts,wasysym}
\usepackage{graphicx}
\usepackage[help]{epspdfconversion}
\usepackage[left=3cm,right=2cm,top=3cm,bottom=2cm]{geometry}
\usepackage[center]{caption}
\usepackage{color}
\setcounter{secnumdepth}{3}
\setcounter{tocdepth}{3}
\usepackage[all]{hypcap}

and when I try to add a figure:

\begin{figure}
\includegraphics[scale=0.5]{ocupfd.eps}
\caption{a}
\end{figure}

the program gives me the following error:

What should I do?

Are you calling pdflatex with the -shell-escape option? If you don't need any of the fancy options of epspdfconversion, maybe \usepackage{epstopdf} will do, without even the command line option, if your TeX distribution is recent. – egreg Nov 14 '11 at 23:39
@egreg How do I execute this -shell-escapeoption? – Rodrigo Thomas Nov 15 '11 at 0:24
It depends on your settings: operating system and editor. – egreg Nov 15 '11 at 0:25
I use Ubuntu, and TeXMaker – Rodrigo Thomas Nov 15 '11 at 0:27
@egreg Could you tell me how do I execute the -shell-escapeoption for the TeXMaker on Ubuntu? – Rodrigo Thomas Nov 15 '11 at 1:21
