## In Linux do "which latex", "which convert" and "which identify" to find the paths which could

Further notes:

1. LatexRender produces GIFs by default - if you prefer PNG then change the variable at the beginning
of class.latexrender.php. Be aware though that ImageMagick may not make PNGs transparent so may show them
with a white background

2. The default is to use article.cls for LaTeX which is a common class but it only supports 10,11,12 point
font sizes. For smaller (or larger fonts) in the image, install the extsizes package available from CTAN
http://ctan.tug.org/" onclick="window.open(this.href);return false;. Add these files to a new extsizes directory in usr/share/texmf/tex/latex.
Refresh the database using "texhash" command, assuming you are using teTeX.
Then in class.latexrender.php you can change var $_font_size = 10; to var $_font_size = 8;

3. You can allow larger images and/or longer latex code by adjusting the default 500 in
class.latexrender.php in the lines
var $_xsize_limit = 500;
var $_ysize_limit = 500;
var $_string_length_limit = 500;

4. You can make equation arrays and other code that starts with \begin, by prefacing them with 2 new lines.

5. Displayed formulae can be rendered using \displaystyle and <center> tag

Eso es un problema por intentar incluir un fichero que no está en ninguna de las rutas autorizadas. En vez de usar la ruta absoluta usa rutas relativas.

Cambia
include("/var/htdocs/foros/latexrender/phpbb_hook_2.php");

Por:
include("../latexrender/phpbb_hook_2.php");

[dNielf]

mmm con los puntos .. ?

[Shaddow]

Si, ¿no funciona?

Ando en lo mismo, al parecer hice todo lo indicado y me sale este errro

Seguí estas instrucciones .. disculpen pero mis conocimientos todavia son de un 5% en todo esto, pero la ando luchando para lograr aprender ...

Off Topic:

PhpBB3 supone que está instalado en / var/www/phpBB3 y se ejecuta en el servidor Ubuntu 7.04 (que también debería aplicarse a Debian Linux también)
1. En el tipo de terminal: sudo apt-get install imagemagick texlive gs
2. Descargar, y desempaquetar latexrender.zip en / var/www/phpBB3/latexrender
3. Añadir los permisos adecuados. En la consola escribir:
Código: Seleccionar todo
sudo chmod -R u=rw /var/www/phpBB3/latexrender
sudo chmod -R g=r /var/www/phpBB3/latexrender
sudo chmod -R o=r /var/www/phpBB3/latexrender
sudo chmod u=rwx /var/www/phpBB3/latexrender/tmp
sudo chmod g=rwx /var/www/phpBB3/latexrender/tmp
sudo chmod o=rwx /var/www/phpBB3/latexrender/tmp
sudo chmod u=rwx /var/www/phpBB3/latexrender/pictures
sudo chmod g=rwx /var/www/phpBB3/latexrender/pictures
sudo chmod o=rwx /var/www/phpBB3/latexrender/pictures

4. Abra el archivo / var/www/phpBB3/latexrender/phpbb_hook_2.php.
5. Reemplazar todas las ocurrencias de dos uid $ en $ bbcode_uid. Debido a los permisos de los ficheros que debe ser root para hacer eso.
6. Reemplace todas las seis apariciones de texto en $ $ mensaje.
7. Abra el archivo / var/www/phpBB3/includes/bbcode.php y en la línea 118 (justo antes de "/ / Eliminar el uid de etiquetas que no se han transformado en HTML"), añadir el texto siguiente:
Código: Seleccionar todo
include("/var/www/phpBB3/latexrender/phpbb_hook_2.php");

8. Abra el Panel de Control Administrativo de phpBB3 utilizando la interfaz web, y en virtud del desplazamiento-> BBCode poner el uso
Código: Seleccionar todo
[tex]{TEXT}[/tex]

y comprobar en la pantalla de envío, y haga clic en Enviar.
9. Opcionalmente se puede querer hacer su propio LaTeX comandos disponibles para los usuarios de foro. Para ello tenemos que añadir a las líneas / var/www/phpBB3/latexrender/class.latexrender.php, entre las líneas 184 y 185:
Código: Seleccionar todo
function wrap_formula($latex_formula) {
$string = "\documentclass[".$this->_font_size."pt]{".$this->_latexclass."}\n";
$string .= "\usepackage[latin1]{inputenc}\n";
$string .= "\usepackage{amsmath}\n";
$string .= "\usepackage{amsfonts}\n";
$string .= "\usepackage{amssymb}\n";
<PUT NEW \usepackage OR \newcommand OR \DeclareMathOperator OR whatever here>
$string .= "\pagestyle{empty}\n";
$string .= "\begin{document}\n";
$string .= "$".$latex_formula."$\n";
$string .= "\end{document}\n";

return $string;
}

Cada LaTeX necesidad de comando envuelto en comillas. También tenemos que sustituir la barra con doble reacción (\ -> \ \), las comillas con barra quatation marca ( "-> \"). Cada línea debe terminar con \ n.
Ejemplo:
Código: Seleccionar todo
$string .= "\\newcommand{\\dbar}{d\\mkern-6mu\\mathchar'26}\n";
$string .= "\\newcommand{\\suchas}[1]{\\Bigr\\rvert_{#1}}\n";

Observaciones:
• Sí, si no queremos añadir comandos personalizados LaTeX, no la edición de class.latexrender.php se requiere en Ubuntu Server.
• Tengo totalmente idea de por qué no en el original cadena literal en función wrap_formula (/ var/www/phpBB3/latexrender/class.latexrender.php, líneas 188) único reacciones no se sustituye con el doble de barras ... Pero si queremos añadir comandos personalizados LaTeX que se corrió, tenemos que utilizar las directrices del punto 9.

Ah, los permitos dados fueron a través del CPanel y se le dio el maximo 777

saludos y gracias por si me pueden dar una luz.
