[GRASS-user] Grass 7.0 - Topology error?

[Richard Chirgwin]

Hi,

I've taken the plunge and installed Grass-7.0 for a look. Attempting a 
v.distance, I'm getting a feature type error. Here is v.info on the "to" 
map:

> GRASS 7.0.svn (Australia):~ > v.info MapB -t
> nodes=0
> points=5113
> lines=0
> boundaries=0
> centroids=0
> areas=0
> islands=0
> primitives=5113
> map3d=0

Here's what happens to v.distance:

> GRASS 7.0.svn (Australia):~ > v.distance from=MapA from_type=centroid 
> to=MapB to_type=point upload=dist column=Dist
> ERROR: No features of selected type found in <MapB at Copy>

Since the maps were copied over from an 6.4 install, I have run v.build 
on all maps.

Environment is Debian (a new install in a virtual machine).

Cheers,
Richard C
