[primer mensaje] problema adaptando raccoonshow

[Pablo Rodríguez]

Hola a todos,

éste es mi primer mensaje a la lista. Soy un novato auténtico en Python
(y no sé programar) y he intentado adaptar raccoonshow para que genere
presentaciones en Flash como las que hace Lawrence Lessig (en concreto
quiero adaptar ésta: http://lessig.org/blog/archives/003696.shtml).

Bien, el problema es que el código (que está debajo), me da cuando lo
invoco "python mracconshow.py -p orphanworks-x -t linetime.txt -w
orphan.mp3", el siguiente error:

Traceback (most recent call last):
  File "mracconshow.py", line 203, in ?
    main(sys.argv[1:])
  File "mracconshow.py", line 201, in main
    back.run()
  File "mracconshow.py", line 152, in run
    self.convertPdf(pdfcheck)
NameError: global name 'pdfcheck' is not defined

Sinceramente, no sé qué falla. Desde mi ignorancia absoluta creo que ése
es el único fallo, fundamentalmente porque he ido cambiando teniendo al
lado el raccoonshow original.

Agradecería si alguien me pudiese decir dónde está el fallo y cuál sería
el código parcheado.

Muchas gracias y perdonad las molestias (me corre cierta prisa).

Saludos,


Pablo
