Hi all,
I have recently installed Mediawiki here at work and everything
is going fine. During the install I thought that I wouldn't need maths
formula rendering so didn't install imagemagic etc. Now it's a case of
"silly me" as there is a mathematician here who used Tex when doing his
PhD and would like to enter maths formula's on his pages.
I've subsequently set $whUseTex to true and then installed
imagemagick etc. I next loaded one of his pages and get in red text:
Failed to parse (PNG conversion failed; check for correct installation
of latex, dvips, gs, and convert):
If I fire up a shell, I'm running Gentoo Linux with the version of
Mediawiki being the latest, and type in:
latex
I get:
This is pdfeTeX, Version 3.141592-1.30.5-2.2 (Web2C 7.5.5)

dvips
I get:

gs
I get:

convert
I get:

If I go into the ....../mediawiki/math directory view the README file
and grab the bit of example code for texvc and run it:
texvc /tmp /home/samba/public "y=x+2" iso-8859-1
I get a nice *.png file with y = x+2 rendered on it.
I think I have all of the appropriate apps in place and within
the PATH, all of the above was entered from
/var/www/localhost/htdocs/mediawiki, although texvc is in the
....../mediawiki/math dir and I had to explicitly go into this dir for
it to run. Can anyone think of what could be wrong and in turn point me
in the right direction so that I can make the mathematician happy.
Either a fix to my problem or where to look to start debugging would be
greatly appreciated.
Regards,
Andrew Lowe
