[Mediawiki-l] math: Failed to parse (unknown error)

[Rob Desbois]

From command-line, try the following:
   sudo apache texvc /mediawiki/images/tmp /mediawiki/images/math "y=x+2" iso-8859-1

If that doesn't work, you should be able to debug from there.
Potential fixes:
try chgrp'ing images/math and images/tmp to apache as well as chown.

If it works on command-line, try viewing your wiki test page via 'edit this page' - I had problems with the page being cached if I viewed it normally.

SUBJECT:   [Mediawiki-l] math: Failed to parse (unknown error)

Hello all:

Can you please help me get math set up right with mediawiki?

Here is the problem: Typing "<math>a + b = c</math>" on a page
produces output that says "Failed to parse (unknown error): a + b =
c".

My OS is Fedora Core 4. I installed mediawiki using instructions on
http://meta.wikimedia.org/wiki/Help:Running_MediaWiki_on_Fedora_Core

I've checked following four things:
-----------------------------------------------------------------------------------
1) I have created directories math and tmp:
$ pwd
/var/www/mediawiki/images
$ ls -l
total 24
drwxrwxr-x  2 apache root 4096 May 19 14:18 math
-rw-r--r--  1 root   root  202 May  7  2004 README
drwxrwxr-x  2 apache root 4096 May 19 14:18 tmp

2) latex, dvips, gs and convert are available:
$ which gs convert latex dvips
/usr/bin/gs
/usr/local/bin/convert
/usr/bin/latex
/usr/bin/dvips

3) Here are some lines from my LocalSettings.php file:
$IP = "/var/www/mediawiki";
$wgScriptPath       = "/mediawiki";
$wgUploadPath       = "$wgScriptPath/images";
$wgUploadDirectory  = "$IP/images";

$wgUseTeX                       = true;
$wgMathPath         = "{$wgUploadPath}/math";
$wgMathDirectory    = "{$wgUploadDirectory}/math";
$wgTmpDirectory     = "{$wgUploadDirectory}/tmp";

$wgEnableUploads                = true;
$wgUseImageResize               = true;
$wgUseImageMagick = true;
$wgImageMagickConvertCommand = "/usr/local/bin/convert";

4) Finally, there is a texvc file in the math directory:
$ ls -l
total 380
-rwxr-xr-x  1 root root 377016 Apr  3 08:48 texvc

-----------------------------------------------------------------------------------
Everything seems okay, but it doesn't work anyway. Any ideas? How do I
test the texvc file on command line?

Thanks,
- Sonali.
