Re: [Mediawiki-l] Secrets for Enabling TeX ?

Here's the rundown on what you need available in the PATH: LaTeX (latex) dvips ImageMagick (convert) GhostScript (gs) Make sure those commands are available in the PATH for the web server. You also need to have installed the support program 'texvc', which verifies the TeX input, produces HTML text if possible, and sends it on to the above programs for rasterization. You'll find texvc in the 'math' subdirectory of the MediaWiki tarball; you'll need ocaml 3.06 or later to compile it. If Ocaml's installed, just go in and run 'make'. (On BSD systems you need to use gmake.) I've put a copy of the binary we use on Wikipedia, which should run without need for installing ocaml, up at: http://download.wikimedia.org/texvc-linux-x86-20040107.tar.gz The texvc binary should go in a 'math' subdirectory under the location where wiki.phtml is (or index.php in 1.2.0). Make sure that the $wgMathDirectory and $wgTmpDirectory variables in the config point to directories that are writable by the web server, and $wgMathPath should point to the URI path to get to the MathDirectory, which is where output .png files are put. The TmpDirectory is used to hold intermediate files. For troubleshooting, you might try manually running texvc to confirm it works; see is README file.
