How do I get the dependencies for the pgfSweave package (e.g. a current PGF) in MikTeX?

Question

I installed the pgfSweave package for color syntax in LaTeX documents, but I ran aground when it comes to a LaTeX dependency. I've installed the pgf package via MikTeX's Package Manager (Admin) and believe to be up to date (I've looked around in the package folder in my MiKTeX install folder, but I have not seen any version numbers). What am I missing?

Answer 1

On MikTex repositories, the used version is apparently 2.00. The latest version 2.10 can be downloaded here. The installation instructions can be find in the manual that is included in the zip file under ...\pgf_2.10.tds\doc\generic\pgf.

If you move the complete folder according to the installation instructions. It boils down to copy the relevant gpf folders from the directory structure in the zip file to the directory structure in you miktex installation. Best is to try a TDS-compliant installation, where you replace the texmf/ in the installation instruction with your miktex installation folder.

Don't forget to refresh the FNDB (filename database) in via the miktex settings app.

Alternatively, you can uninstall the pgf package and place the unzipped directory tree somewhere where Tex can find it. Again, don't forget to refresh the FNDB. Note though that the installed pgf package will have folders in different places of the directory tree of MikTex. So don't just paste everything you find on one folder you find in the directory system.

EDIT :

To know the pgf version that is loaded in your tex distribution, try following small document :

\documentclass{article}
\usepackage{tikz}
\begin{document}
\pgfversion
\end{document}
