Re: [Phpwiki-talk] Visualization with GraphViz dot

[Reini U. <ru...@x-...>]

Hi Walter,

I compiled dot on my own linux machine and copied it to the sf.net server.

Two things: Be sure that the dependent so's match the ones you have at
or host, (best not to rely on any .so, which is what I did on sf.net)
and be sure to check the font paths, so that the default font will be
picked up automatically.

Yes, because I again changed VisualWiki to inherit from the the new
GraphViz plugin, and this inherits from the enhanced WikiPluginCached.
(to support image maps for Ploticus)
And this execute method is broken again for linux. (to catch STDERR)
