[Mediawiki-l] math/texvc problem

Hello, I'm trying to make TeX formula working in MediaWiki under Windows. It doesn't work yet (experiments are described in the preceding mail). I tried manual test of texvc.exe texvc.exe "c:\temp" "c:\temp" "x^2" The displayed output: --------------------------------------------------------------------------------- latex: unrecognized option `-quiet' gs: Interpreter revision (854) does not match gs_init.ps revision (707). gs: Interpreter revision (854) does not match gs_init.ps revision (707). convert: no decode delegate for this image format `c:\temp\1996_caeec96a64f7a8a9 edff9788f38e8083.ps'. convert: Postscript delegate failed `c:\temp\1996_caeec96a64f7a8a9edff9788f38e80 83.ps'. convert: missing an image filename `c:\temp\caeec96a64f7a8a9edff9788f38e8083.png '. ccaeec96a64f7a8a9edff9788f38e8083<i>x</i>² + <i>z</i>⁴ + < i>z</i>⁸ --------------------------------------------------------------------------------- but nothing was saved in c:\temp. Can anybody explain to me, what's going on there? Imagemagik's convert works well... Problem of ghostscript?? Why there is nothing saved to in c:\temp?? When I tried the original render.ml, the file 1996_af70815e91e661db930956cdd84e0b52.tex was saved to c:\temp with correct TeX code \nonstopmode \documentclass[12pt]{article} \pagestyle{empty} \begin{document} $$ x^{2} $$ \end{document} but mediawiki wrote "Failed to parse(unknown error): x^2", when I wrote <math> x^2</math> on the page. So I change the render.ml as adviced in http://meta.wikimedia.org/wiki/Running_Mediawiki_on_Windows and then received the result above... Any hint, what's wrong here? Martin
