[GRASS-user] Installing r.viewshed add-on in GRASS 6.4.3 in Windows 7

GRASS GRASS user

Hi all,

I am a newbie to GRASS and i recently installed GRASS 6.4.3 for Windows 7. When I try to add r.viewshed add-on, it gives an error as follows:

g.extension.py extension=r.viewshed svnurl=http://svn.osgeo.org/grass/grass-addons/grass6
Downloading precompiled GRASS Addons <r.viewshed>…
ERROR: GRASS Addons <r.viewshed> not found
(Wed Dec 19 20:17:56 2012) Command finished (1 sec)

Could somebody help to solve this?

Cheers, Brian.

Did you use the installation from the graphical user interface,
right?

The addon for winGRASS is precompiled there:
http://wingrass.fsv.cvut.cz/grass64/addons/grass-6.4.3svn/

I am not sure why this fails for you. Others, any idea?

Thanks. Yes with Graphical user interface. In that I used running with
Coomand output, but the same error.
Initially i got and error saying following:

ERROR: Unable to create 'C:/Program Files/GRASS GIS 6.4.3RC1\man\man1':
[Error 5] Access is denied: 'C:/Program Files/GRASS GIS 6.4.3RC1\\man'

I am not on Windows myself, hence no idea.

Commonly we suggest to not install GRASS in paths with white space.

Regarding your other offlist question: no compiler needed since the
installer will just fetch the ZIP'ed executable from our server and
unpacks it.

Hi, Markus

I could install r.viewshed without any trouble with GRASS 6.4.3svn from SVN nightly built version. It does not work with stable winGRASS 6 probably a bug!.

Cheers, Brian.
