Bug 7445

Changing the summary to be more general.  For reference, comment 1 refers to 
mediawiki-addMathextensionToInstances.

--------------------------------
To use this extension, you have to add
the following lines to your LocalSettings.php

require_once("/usr/share/mediawiki/extensions/Math/Math.php");
$wgTexvc = "/usr/share/mediawiki/extensions/Math/texvc";

Then run mediawiki-addMathExtensionToInstances as root.

In addition make sure the variables $wgMathDirectory,
$wgMathPath and $wgTmpDirectory are set as well as the
more general variables $wgEnableUploads and $wgUploadPath
according to your wiki instance paths.

Then run mediawiki-updateall to update the databases of
your mediawiki instances.

For more information, see http://www.mediawiki.org/wiki/Extension:Math
-------------------------------------


$wgTexvc gives an incorrect path to texvc executable.
$wgTexvc = "/usr/share/mediawiki/extensions/Math/texvc";
should be..
$wgTexvc = "/usr/share/mediawiki/extensions/Math/math/texvc";

The paragraph starting 'In addition..' needs some clarification. Where should these variables be set? They are not present in LocalSettings.php but I think that is where you mean. Could you add some more info about them please.

I tested with the <math> example from here:http://www.mediawiki.org/wiki/Manual:Math

This is the result..

Failed to parse (PNG conversion failed; check for correct installation of latex and dvipng (or dvips + gs + convert)): \operatorname{erfc}(x) = \frac{2}{\sqrt{\pi}} \int_x^{\infty} e^{-t^2}\,dt = \frac{e^{-x^2}}{x\sqrt{\pi}}\sum_{n=0}^\infty (-1)^n \frac{(2n)!}{n!(2x)^{2n}}

I may just be missing some part of the configuration, mathpath or mathdirectory or something but not sure.

Summary: Mediawiki-math README.urpmi gives mediawiki-addMathExtensionToInstances - should be mediawiki-addMathextensionToInstances => Mediawiki-math README.install.urpmi gives unclear instructions

Created attachment 2805 [details]
Debug log using the math extention.

Following the same <math> example as Claire, ends in the same results:

Failed to parse (PNG conversion failed; check for correct installation of latex and dvipng (or dvips + gs + convert)):    \operatorname{erfc}(x) = ... 

In the code, that error is printed because the png file is not found. There doesn't appear to be any other errors in the log. 

FYI: I stumbled into a new feature (as of 1.19) that is somewhat helpful here. Adding this line to LocalSettings.php:

$wgDebugToolbar = true;

Puts a bar across the bottom of the window with some useful information, including the debugging log.

Even if a higher version, we do still have the same package:


Sat Jan 12 2013 umeabot <umeabot> 1.0-1.110614.3.mga3

+ Revision: 359908

Reassigning to bugsquad, there is no dedicated maintainer for this package anymore.

And now assigning to all packagers collectively, since we have a dedicated bugzilla user and mailing list for that.
