Just take a look at the samples in the zip file.
You can post latex codes on your forums which will generate a picture with the formular.

please attach the compiled mimetex.cgi as a zip file....

and if you want give us more infromations about the installation ...

I am not a profissional like you :tired:

thanks and best regards

As I said in my first post, I don't know if I can do this nor do I know if there is anything server specific in my CGI file.
Here a quote from the install README:
Quote:
QUICK START
------------------------------------------------------------------------
To compile and install mimeTeX
* unzip mimetex.zip in any convenient working directory
* to produce an executable that emits anti-aliased
gif images (recommended)
cc -DAA mimetex.c gifsave.c -lm -o mimetex.cgi
-or- for gif images without anti-aliasing
cc -DGIF mimetex.c gifsave.c -lm -o mimetex.cgi
-or- to produce an executable that emits mime xbitmaps
cc -DXBITMAP mimetex.c -lm -o mimetex.cgi
(For Windows, see "Compile Notes" in Section III below.)
* mv mimetex.cgi to your server's cgi-bin/ directory
* mv mimetex.html to your server's htdocs/ directory
* if the relative path from htdocs to cgi-bin isn't
../cgi-bin then edit mimetex.html and change the
few dozen occurrences as necessary.
Then, to quickly learn more about mimeTeX
* point your browser to www.yourdomain.com/mimetex.html
Any problems with the above?
* read the more detailed instructions below,
or see http://www.forkosh.com/mimetex.html

This is very complex way .... :cry: :cry: :cry: :cry: :cry:


Can you give me another way to compile the cgi file ? please ?


Thanks & best regards

I've just installed this and have followed the directions thoroughly. Note that there's a missing close quote and ; from line 11 of the functions_mimetex.php in the zip file.

When I try to put an equation in a thread, I now get an error message:

Warning: system() has been disabled for security reasons in /includes/functions_mimetex.php on line 49

How do I address this error message? I see the system() call is what's actually referencing the cgi file, so it's clearly critical to this functionality.

edst 08-31-2005 04:04 PM
Okay, I've found a workaround. So if you cannot use system calls on your system, replace all the lines inside the $do_latex loop as follows:
Code:
    if($do_latex) {
            $mimetex_formula = $tex_matches[1][$i];
          $text = substr_replace($text, "<img src='".$cgi_path."?".$mimetex_formula."' alt='".htmlentities($mimetex_formula, ENT_QUOTES)."' align=absmiddle>",$pos,strlen($tex_matches[0][$i]));
    }
Where $cgi_path is defined at the top as:
Code:
        $cgi_path = "http://yourdomain/cgi-bin/mimetex.cgi";
There are no images stored with this method, so some could be trimmed down from the initial php code too.

edit: cleaned up the img tag a bit.
