[Mediawiki-l] setting environmental variables for a wiki

[Emma Gottesman]

I'm trying to get the math formatting working on my wiki.  I've 
installed OCaml and teTeX but I'm having problems with ImageMagick. I'm 
running on Solaris 10.  The texconfig for the teTex installation works fine.

As part of the set-up I need to set the environmental variables 
MAGICK_HOME and LD_LIBRARY_PATH.
I've got the following lines in /etc/profile
export MAGICK_HOME="/usr/local/ImageMagick-6.2.1"
export LD_LIBRARY_PATH="/usr/local/ImageMagick-6.2.1/lib:$LD_LIBRARY_PATH"
and I've got them again in /.login and /.profile.

However, I'm getting the error
*Failed to parse (PNG conversion failed; check for correct installation 
of latex, dvips, gs, and convert): \int_{s=a-1}^{b} f(s)\, ds \le 
\sum_{i=a}^{b} f(i) \le \int_{s=a}^{b+1} f(s)\, ds*
on a sample math equation I've got.

How do I set an evironmental variable for the wiki? What user is it?  I 
think it may be webservd:
(extract from /etc/passwd) **webservd:x:80:80:WebServer Reserved UID:/:
and that has no home directory or shell so I can't set it in ~/home.

Just in case it makes a difference the wiki is installed in 
/var/apache2/htdocs/wiki. Also I've enabled $wgUseTeX in 
LocalSettings.php and the make in /var/apache2/htdocs/wiki/math 
generated no errors.

Help?

PS
I used symbolic links from /usr/local/bin instead of setting the PATH 
for dvips, convert etc:
root[k)(sh]@sunray21#which latex
/usr/local/bin/latex
root[k)(sh]@sunray21#which dvips
/usr/local/bin/dvips
root[k)(sh]@sunray21#which convert
/usr/local/bin/convert
root[k)(sh]@sunray21#which gs
/usr/sfw/bin/gs
