LaTeX Error: Environment tikzpicture undefined

[urcindalo]

Hi and thanks for reading this.

I use QtiPlot a lot, and this package can export .tex graphics, which can later be compiled in Latex.

The problem is whenever I load the .tex file into Texmaker (v1.92, stable for amd64) and try a quick compilation, I get this error:

Code: Select all

! LaTeX Error: Environment tikzpicture undefined.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
...
l.1 \begin{tikzpicture}
{0pt}{0pt}{502pt}{376pt}
Your command was ignored.

The beginning of the QtiPlot-generated .tex is this:

Code: Select all

\begin{tikzpicture}{0pt}{0pt}{502pt}{376pt}
	\clip(0pt,376pt) -- (377.912pt,376pt) -- (377.912pt,92.9425pt) -- (0pt,92.9425pt) -- (0pt,376pt);
	\color[rgb]{1,1,1}
	\fill(3.76406pt,372.236pt) -- (370.384pt,372.236pt) -- (370.384pt,103.482pt) -- (3.76406pt,103.482pt) -- (3.76406pt,372.236pt);
	\fill(45.1688pt,366.966pt) -- (362.103pt,366.966pt) -- (362.103pt,140.37pt) -- (45.1688pt,140.37pt) -- (45.1688pt,366.966pt);
\begin{scope}
	\clip(45.1688pt,366.966pt) -- (362.103pt,366.966pt) -- (362.103pt,140.37pt) -- (45.1688pt,140.37pt) -- (45.1688pt,366.966pt);

I have dev-tex/pgf-2.00 installed as a dependency for app-text/texlive-2008, dev-tex/latex-beamer-3.07 and sci-visualization/gnuplot-4.4.2.

Am I missing something? Is the stable texlive installation in Gentoo incomplete?

Thanks in advance.

Do you have the proper line in the preamble of your file (i.e. \usepackage{tikz}) ?

Also, I think you can not compile these generated files directly. You need to embed them in another document or give a proper preamble.
