Hola Daniel!

Mi consulta es con respescto a Lua.
Tengo la maquina virtual de Ginga sobre Kubuntu.
Los archivos .ncl los ejecuta bien.
Ahora cuando quiero agregar dependencias a un archivo .lua   ya no funciona bien.

La Aplicacion corresponde a un punto del Test Suite 1.2.0----> http://tvd.lifia.info.unlp.edu.ar/ginga.ar/index.php/testsuite-menu )
(La aplicacion muestra sobre un fondo azul:

a la izquierda y de arriba hacia abajo:

-un rectangulo vacio y de borde blanco

- un rectangulo blanco lleno

- 16 lineas horizontales de color verde cuya opacidad dismi-

nuye de arriba a abajo

a la derecha y de arriba hacia abajo:

- un logotipo

- textos dibujados utilizando distintos tama~nos, estilos y co-

lores de fuentes. )

Me explico mejor ... el código ncl es:

------------------------- el NCL ----------------------------------------
<?xml version="1.0" encoding="ISO-8859-1"?>
<ncl id="canvas" xmlns="http://www.ncl.org.br/NCL3.0/EDTVProfile">
    <head>
        <regionBase>
            <region id="reg" width="100%" height="100%" left="0%" top="0%" />
        </regionBase>
        <descriptorBase>
            <descriptor id="desc" region="reg"/>
        </descriptorBase>
    </head>
    <body>
        <port id="pLua" component="lua" />
        <media id="lua" src="30_canvas.lua" descriptor="desc" />
    </body>
</ncl>

--------------------------- Lua -----------------------------------------
--background
canvas:attrColor('navy')
canvas:clear()

--top left
canvas:attrColor('white')
canvas:drawRect('frame', 50, 50, 250, 100)
canvas:drawRect('fill', 50, 200, 250, 100)

-- top left
for i=0, 15 do
    canvas:attrColor(0, 255, 0, 255 - (i * 16) )
    local y = 50 + (i * 10)
    canvas:drawLine(525, y, 680, y)
end

-- right
image = canvas:new('../resources/images/logo.jpg')
canvas:compose(325, 50, image)

local colors = {"white", "black", "silver", "gray", "red" , "maroon" , "fuchsia", "purple", "lime", "green", "yellow", "olive", "blue", "navy", "aqua", "teal"}
local fontWeight = {"normal", "bold", "italic"}
local fontFamily = {"Tiresias", "Tiresias"}

for i=0, 7 do
    for j=0,2 do
        local ff = ''
        if i < 4 then
            ff = fontFamily[1]
        else
            ff = fontFamily[2]
        end
        local fw = fontWeight[j + 1]
        local offset = i * 2 + j
        canvas:attrFont(ff, 14 + offset, fw)
        canvas:attrColor(colors[i * 2 + (j % 2) + 1])
        canvas:drawText(40 + 225 * j , 310 + 30 * i, ff .. ' ' .. fw)
    end
end

-- flush
canvas:flush()

---------------------------------------------------------------------------

y el Error al compilar dice esto:

... si ejecuto un codigo lua simple como :

canvas:attrColor('blue')
canvas:clear()
canvas:flush()

No se produce ningun Error.

Podra ser alguna libreria que me falte de Lua?
... o nose que puede ser :?

desde ya Muchas Gracias Daniel!!!!!!

Saludos!
