Mime-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Content-Disposition: inline Thank you, Rob. Okay, here's something. The command you suggested did not work as it is. However, after a bit of tweaking, I got it to create a .png file in the images/math directory. Here is what I needed to change: 1) sudo apache --> sudo -u apache. This is trivial. 2) texvc --> ./texvc. It gave me a message: "sudo: ignoring `texvc' found in '.' Use `sudo ./texvc' if this is the `texvc' you wish to run." otherwise. 3) /mediawiki/images/tmp --> /var/www/mediawiki/images/tmp, and similarly for math. With these changes, it worked. The command "sudo -u apache ./texvc /var/www/mediawiki/images/tmp /var/www/mediawiki/images/math "y=x+2" iso-8859-1" created a .png file in the math directory. How do I see a .png file, by the way? I am sure this is hinting at a resolution of the problem, but I am not sure what it is saying. :-) I tried modifying the LocalSettings.php file in the obvious ways: 1) Tried adding math directory to the path: Changed "ini_set( "include_path", ".:$IP:$IP/includes:$IP/languages" );" to "ini_set( "include_path", ".:$IP:$IP/includes:$IP/languages:$IP/math" );" This did not work. 2) Just for the heck of it, tried changing $wgScriptPath from /mediawiki to /var/www/mediawiki, but this generated some errors when I tried to save a page on the wiki, so I changed that back. Any other suggestions what I can try? Thanks again, - Sonali.
