Hi Maurizio,
Things keep getting stranger and stranger... indeed, I'm not getting any output from the texvc command, although the command itself seems to be correct:
TeX: ./math/texvc '/var/www/html/wiki/images/tmp' '/var/www/html/wiki/images/tmp' '\sqrt{n^2}' 'UTF-8' TeX output:
--- OutputPage::sendCacheControl: private caching; ** Request ended normally [bgoncalves@azrael wiki]$
And if I run the command manually from the wiki directory, it works fine:
[bgoncalves@azrael wiki]$ pwd /var/www/html/wiki [bgoncalves@azrael wiki]$ ./math/texvc '/var/www/html/wiki/images/tmp' '/var/www/html/wiki/images/tmp' '\sqrt{n^2}' 'UTF-8' +7db31f1ef8b4b7d1bfcc94576455fa0a[bgoncalves@azrael wiki]$
with the png image ending up in /var/www/html/wiki/images/tmp. Anything else you can think of? Thanks for all the help!
Bruno

Hi Maurizio,
- you have to have dvipng installed, in addition to LaTex
I do.
- if texvc is not run you see a red box telling you so where you'd
normally expect math equations to appear.
I see red letters saying "*Failed to parse (unknown error): \sqrt{n}"*
This means that texvc is run but Math.php doesn't understand the returned HTML or (more likely) you get no output from texvc. In Math.php line 69 you can print the variable $content and see what it looks like. If you're under Windows I'd investigate the communication between PHP and the subprocess running texvc.
I have modified texvc so as not to delete the auxiliary files. I couldn't find anywhere on Math.php where it did this.
You're right. That's in texvc. Bad memory.
Any more ideas?
I'm afraid not. Unfortunately I don't know much of PHP and I have to fight my way through these things by trial and error.
