I'm sorry but it didn't work.
I have reinstalled the addon but it didn't work, reinstalled GRASS 6.4
and neither, then installed GRASS7 again, and appears this message:
r.viewshed -b input=Portada@inisig output=visPort
coordinates=-3.74034324324,42.5352702703 obs_elev=9 tgt_elev=1.75

cumple.
I will try in another PC.
Thank you for your time.

Hi everyone,
when I try to run r.viewshed the output shows me this:
(in GRASS 6 it is an Addon)

Anyone has a clue about what it could be happening?
I'm using GRASS 6.4.4 in Xubuntu 14.04.
I have backported some fixes from GRASS 7 to the addon in GRASS 6.
Please reinstall the addon with g.extension and try again.
I think I must say that a few days ago I installed GRASS 7 but I removed it
and reinstalled GRASS 6.4.4. Maybe is there any incompatibility?
No, GRASS 6 and 7 can happily live together.
Please let us know if the updated Addon runs ok for you.
Markus
