[ZOO-Discuss] Error when running GRASS processes

Sun May 1 17:13:21 PDT 2011

Hi Soeren,

I've been correcting gms/Testing/Python/XML/v.voronoi.xml but I keep
having the following error:

<?xml version="1.0" encoding="utf-8"?>
<ows:ExceptionReport xmlns:ows="http://www.opengis.net/ows/1.1"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xml:lang="en-US" version="1.1.0">
  <ows:Exception exceptionCode="NoApplicableCode">
    <ows:ExceptionText>Python module v.voronoi cannot be loaded.
</ows:ExceptionText>
  </ows:Exception>
</ows:ExceptionReport>

Here's my /usr/lib/cgi-bin:

root at grass:/usr/lib/cgi-bin# ll

drwxr-xr-x   3 root root  12288 2011-05-02 12:04 ./

-rwxr-xr-x   1 root root 355333 2011-04-28 14:45 zoo_loader.cgi*

Here's the content of v_voronoi.* and v.voronoi.xml:

root at grass:/usr/lib/cgi-bin# more v_voronoi.zcfg | grep voronoi
[v_voronoi]
Abstract = http://grass.osgeo.org/grass70/manuals/html70_user/v.voronoi.html
serviceProvider = v.voronoi
root at grass:/usr/lib/cgi-bin# more v_voronoi.py | grep voronoi
def v_voronoi(m, inputs, outputs):
    service.fromMaps("v.voronoi", inputs, outputs)
root at grass:/usr/lib/cgi-bin# more gms/Testing/Python/XML/v.voronoi.xml
| grep voronoi
                <ows:Identifier>v.voronoi</ows:Identifier>

<ows:Abstract>http://grass.osgeo.org/grass70/manuals/html70_user/v.voronoi.html</ows:Abstract>

Obviously the problem is that ZOO cannot find the v.voronoi module.
But I can't really understand if this is a problem of GRASS config in
GlobalGrassSettings.py, or a problem in the v_voronoi.* files.

Cheers,

Pierre
