[Mediawiki-l] Math Problems

[Andreas Schwarz]

Hello,

I installed Mediawiki 1.1.0, but there are no PNG images generated for
math formulas.

latex, dvips and convert are in the path and executable by the
webserver, and the following paths are writable:

$wgMathDirectory    = "/var/www/wiki.mikrocontroller.net/upload/math";
$wgTmpDirectory     = "/var/www/wiki.mikrocontroller.net/upload/tmp";

HTML formulas are displayed correctly, but no PNG image is created, both
$wgMathDirectory and $wgTmpDirectory are empty. The following message
appears in the Apache error log every time a formula is changed:

This is dvips(k) 5.86e Copyright 2001 Radical Eye Software (www.radicaleye.com)
' TeX output 2004.02.03:1832' -> 
<texc.pro>. [1]

Any hints?

Andreas
