Problem with drawLabelCache on openSUSE

[Daniel Morissette]

Dimitris,

It's possible the FGS binaries had some problems, we know there were 
problems with them on some platforms and badly need to refresh what's 
available on the download site. Have you tried configuring PHP as a CGI 
and see if that helps? You'd do that by changing the 
www/conf.d/php4.conf and restarting FGS, if I remember correctly there 
are sample config files for both PHP as CGI and PHP as module in that 
directory.
You could also try using the latest "FGS-msx" that contain more recent 
versions of everything, including daily builds of the latest MapServer 
5.0.0 release candidate code:
