Topic on Project:Support desk

I've gone through all the instructions over and over and nothing seems to be working with Tex. I've added these lines into LocalSettings.php:

all the sub-programs run just fine from the command line, latex, convert, gs, dvips, no problem. if I run the command:

  texvc /var/wiki/images/tmp /var/wiki/images/math "y=x+2"

I get an image in the /var/wiki/images/math directory, as I expect.

I added these lines to the LocalSettings.php file: $IP = '/var/wiki'; require_once( "$IP/extensions/Math/Math.php" ); $wgUseTex = true; $wgTexvc = '/usr/bin/texvc'; $wgMathDisableTexFilter = true; $wgMathCheckFiles = true; $wgUploadPath = "/var/wiki/images"; $wgUploadDirectory = "/var/wiki/images"; $wgMathPath = "{$wgUploadPath}/math"; $wgMathDirectory = "{$wgUploadDirectory}/math"; $wgTmpDirectory = "{$wgUploadDirectory}/tmp";

I went into the wiki/maintenance directory and did 'php update.php' and no errors. Then I restarted apache.

However, if I go to the page: wiki/index.php?title=Special:Version on the wiki, it shows that the Math extension is NOT installed. No error message, nothing, it just doesn't see it, apparently.

I also notice I do not have a file /wiki/includes/Math.php...

and anything between tags is just ignored, not parsed into math images by the wiki.

So... What am I doing wrong? How do I enable the Tex / math extension here? I'm pulling my hair out!

To make sure we talk about the same thing, could you link to the "instructions" you refer to?

Here are the pages I have examined in effort to get the Tex / Math extension working:

Specifically, I'm running version 1.20 so I downloaded the extension from here:

http://www.mediawiki.org/wiki/Special:ExtensionDistributor?extdist_extension=Math&extdist_version=REL1_20&extdist_submit=Continue

But that was only after I had also installed OCaml and used Git to try installing the extension directly, with texvccheck, as per the instructions here:

http://www.mediawiki.org/wiki/Extension:Math

which built fine, but still did nothing towards actually enabling the extension. As I said, I can generate images from the command-line directly into /var/wiki/images/math as a target dir, so the back-end LaTeX stuff on the server seems to be fine.

I found there are two directories, /etc/mediawiki-extensions/extensions-enabled, and /etc/mediawiki-extensions/extensions-available. The only thing inside of /etc/mediawiki-extensions/extensions-enabled was wikidiff2.php, as a symbolic link to the wikidiff.php file in /etc/mediawiki-extensions/extensions-available. So I added another symbolic link there for Math.php. This had no effect. How does the wiki server normally move extensions from "available" to "enabled", and how can I get some feedback from that process to see why Math.php is not enabled?

I found a type above, my line

$wgUseTex = true;

should have been

$wgUseTeX = true;

With a capital X at the end there on $wgUseTeX, but that also made no difference, still not enabled. Ok. So I go searching for error messages on the server. I found that if you include:

$wgDebugLogFile = "/var/log/wiki.log";

in LocalSettings.php, you can get some info in the logs. So I find that when I do 'php update.php' from within the maintenance/ folder, I see this in the error logs:

..> Start command line script update.php

..> CACHES: EmptyBagOStuff[main] SqlBagOStuff[message] SqlBagOStuff[parser]

..> LocalisationCache: using store LCStore_Null

..> Fully initialised

..> Connecting to localhost my_wiki...

..> Profiler::instance called with bogus $wgProfiler setting, falling back to ProfilerStub for safety

..> Connected to localhost my_wiki.

..> DatabaseBase::query: Writes done: UPDATE `page` SET page_random = RAND() WHERE page_random = 0

..> SQL ERROR (ignored): Table 'my_wiki.profiling' doesn't exist (localhost)

..> Class ConvertUserOptions not found; skipped loading

That's all I have so far. I was about to go digging into:

http://www.mediawiki.org/wiki/Extension:Configure

unless you have some better advice... It doesn't look like 'Math' or 'Tex' are supported extensions for the "configure" tool, but I thought it might give me some more info at least...

Hmmmmmm, some more interesting stuff going on with our server. I tried adding the FootNote extension, just to see if I could get ANY extension working. So I add the line:

require_once( "$IP/extensions/Footnote/Footnote.php" );

and do 'php5 update.php',

but this time update.php gives no response, nothing shows up in the /var/log/wiki.log either. The Footnote extension is not enabled. Hmmm seems that our wiki server is somehow crippled for extensions. I may need to just reinstall the whole thing. How can I do this without losing all the current content? Or maybe there is another option to troubleshoot this issue? Please help?

Did you ever find a solution to this? I have the exact same problem. I'm running fedora 20. I keep getting "unknown error". I have followed every step. I have given up.

Mfort123, please create a NEW post for this. You say you have the exact same problem, but the original poster didn't mention unknown error
