Formula doesn't appear...

Hello,

on my old server all worked well. I have transfered Moodle on a new server with Linux FreeBSD, I have activated the filter but the formula appears how to come writing. I don't have errors but simply the filter seems doesn't work.

Some idea?

Thanks
Federico

I am new at this, but I noticed that you need a different mimetex for every installation. If your operating system is different from what is was originally, you may need to go to www.moodle.org/download/mimetex/freebsd and download that mimetex to work with your new installation.

Good luck,
Tom

The first thing you want to do is activate your tex debugger:

Hallo Zbigniew, (sorry for my english blush )

Much thankful for the answer, i have recalled the file texdebug.php and to appear this:

Your system is not configured to run mimeTeX. You need to download the appropriate
executable from http://moodle.org/download/mimetex/, or obtain the C source
from http://www.forkosh.com/mimetex.zip, compile it and put the executable into your
moodle/filter/tex/ directory. You also need to edit your moodle/filter/tex/pix.php file
by adding the line
       case "FreeBSD":
           $cmd = "\"$CFG->dirroot/$CFG->texfilterdir/mimetex.freebsd\" -e \"$pathname\" ". escapeshellarg($texexp);
You also need to add this to your texdebug.php file.

then I have uploaded the file for FreeBSD  http://moodle.org/download/mimetex ...but I have to compile? Because is not already compiled? Some it may do for me? I don't know to do...

thank you very much
Federico

You do not need to compile the executable file you get from http://moodle.org/download/mimetex/. Just put it in your filter/tex/ folder and set its file permissions to 755 or 777. You also do not need to edit your pix.php or texdebug.php

There are two different filters which use mimetex
  1. algebra filter which uses @: @@@x/2@@@ ==> @@x/2@@
  2. tex filter which uses $: $$$\frac{x}{2}$$$ ==> $$\frac{x}{2}$$
