Mediawiki Math Extension
was simple - upgrade to MediaWiki-1.6.3. Bonza! [[Joejk2 14:47, 29 April 2006 (UTC)]] Still having problems.... Can anybody please suggest why certain symbols fail to render correctly in my install. Something like P ( r ) α r n − 1 exp ( − k r 2 / 2 σ 2 ) {\displaystyle P(r)\alpha r^{n-1}\exp(-kr^{2}/2\sigma ^{2})} renders beautifully whereas replacing the \alpha with a \propto causes download texvc the whole equation to be shown without rendering as P(r) \propto r^{n-1} \exp(-kr^2/2\sigma^2) Certain other symbols also don't work e.g. \nabla and \sim. The strange thing is that perfect png images are created in my images/math folder - just for some reason they are not correctly displayed. Many thanks in advance. Joejk2 18:55, 3 May 2006 (UTC) The reason the above works is that it doesn't have to make a png to lay it out (it's all html). I think you should make sure your latex, dvips, convert are working. m:Help talk:Running MediaWiki on Mac OS X this link shows you how to do that in the OS X section. Basiclaly, execute Check that you got something that worked using a command line like ./texvc '/Library/WebServer/Documents/wiki99/images/tmp' '/Library/WebServer/Documents/wiki99/images/math' '\int_{-N}^{N} e^x\, dx' 'utf-8' (As before, replace the two wiki99/images paths with the math and tmp paths we just created above. Assuming this worked, we should get a cryptic line of output, This is dvips(k) 5.95a Copyright 2005 Radical Eye Software (www.radicaleye.com) ' TeX output 2005.07.23:0928' ->

Hide topic Mfort123 (talkcontribs) I have pretty much given up on troubleshooting this issue. I simply cannot get math/Latex to work. mediawiki texvc windows Here is the relevant information about my setup: Operating system: Fedora 20 mediawiki mathjax Mediawiki version: 1.23.5 Database server: MySql 5.6.21 PHP: 5.5.17 (apache2handler) LocalSettings.php: $wgEnableUploads = true; $wgUseImageMagick = true; $wgImageMagickConvertCommand mathoid = "/usr/bin/convert"; require_once("$IP/extensions/Math/Math.php"); $wgUseTeX =true; $wgUploadDirectory = "{$IP}/images"; $wgUploadPath ="{$wgScriptPath}/images"; $wgMathPath = "{$wgUploadPath/}math"; $wgMathDirectory = "{$wgUploadDirectory}/math"; $wgTmpDirectory = "{$wgUploadDirectory}/tmp"; $wgTexvc ="{$IP}/extensions/Math/math"; $wgDebugLogFile="{$IP}/images/tmp/logfile.log"; Troubleshooting already done: Did not forget to https://www.mediawiki.org/wiki/Manual_talk:Troubleshooting_math_display_errors use php ./maintenance/update.php after changing my LocalSettings.php file. I have a tmp and math directory in /images. They have group owner "apache" with the appropriate permissions (775). I checked texvc by issuing this command in the terminal (with the appropriate directory names changed): texvc /home/wiki/tmp /home/wiki/math "y=x+2" iso-8859-1 "rgb 1.0 1.0 1.0" and everything is fine (the file https://www.mediawiki.org/wiki/Thread:Project:Support_desk/Failed_to_parse_(unknown_error)_when_using_the_math_extension/reply is created in the math directory). I tried editing my page with SELinux turned off by using "setenforce 0" and I still get "unknown error" when using math. I've made every relevant .php and .php5 file executable with group owner set to "apache". I've check the Special:Version page and the math extension is correctly installed. Here is the log file that is generated after trying to access the wiki page: Start command line script ./maintenance/update.php [caches] main: EmptyBagOStuff, message: SqlBagOStuff, parser: SqlBagOStuff [caches] LocalisationCache: using store LCStoreNull Fully initialised Connected to database 0 at localhost 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) I tried placing the latex.fmt file in the /images/tmp directory and that still doesn't work. Final comments: I've followed every troubleshooting method that I could find through web search and nothing has worked. At this point, I have given up and I'm asking for some help.

I checked the LocalSettings.php file, and I have set the proper variable($wgUseTeX) to true.

threaded view ♦ ♦ | Report Content as Inappropriate ♦ ♦ math: Failed to parse (unknown error) 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?
