I am running Mediawiki on my web site.

I would like to use the TEX math extension.

After running make in the math sub directory,

I get the following error when displaying a page with

I = \frac{P}{A} = \cfrac{P}{4pr^2}

in the source.

Failed to parse (Missing texvc executable; please see math/README to configure.): I = \frac{P}{A} = \cfrac{P}{4pr^2}

What am I doing wrong?
