LaTeX Failed to Parse(Unknown Error) on MediaWiki

Question

On my wiki implemented by the MediaWiki interface, I am receiving a Failed to Parse (Unknown Error) for the LaTeX in the page. I checked the LocalSettings.php file, and I have set the proper variable($wgUseTeX) to true.

If it helps, the error message before this was a Failed to Parse(Missing texvc executable), but I "fixed" it to the best of my knowledge by running "make" inside the math directory and installing the texvc executable there. I tested texvc and it works on the commandline.

Could there be anything that I am missing?

Answer 1

Have a look at the README file, paying particular attention to "Ensure that the temporary and math directories exist and can be written to by the user account the web server runs under; if you don't control the server, you may have to make them world-writable."

If that does not help, edit render.ml, comment out the block that says "Commenting this block out will aid in debugging", and re-run make. This will leave all temporary files (including the TeX log) so that you can hopefully see what went wrong.

Answer 2

Found the answer here: MediaWiki Forums LaTeX Error

It seems that I had to clear the math directory except for the original files, rebuild ocaml, and finally rebuild texvc.
