[GRASS-user] Grass 6.3 on OS X

Hi,

In using the William Kyngesburye build on Mac OS X, I have a persistent problem with vector files. Even where I have built the vector inside Grass (for eg, by importing a shapefile such as the outline of Australia), there is a coor file problem. Step by step:

1) Start Grass
2) Import shapefile
3) Select new vector file
4) Display - OK.

5) Exit Grass
6) Restart Grass

7) Select vector file
8) Display

At (8), Grass says the Coor files is larger than it should be, and asks me to rebuild the topology. It will not display the file. V.build doesn't fix the problem.

Any suggestions?

I think this is another example of an issue importing certain shapefiles via
OGR. There has been a thread discussing this on this list over the past few
days. I didn't follow it closely, but you need to set one of the flags
(don't create topology??).

at step 5, what is your exact method of exiting GRASS?
File->Quit and then "exit" in the terminal window?

were is your GRASS data stored? /Users/you/grassdata/ ?

try without the GUI? from the command prompt:

v.in.ogr out=<map>
v.info <map>
g.region vect=<map>
d.mon x0
d.vect <map>
