[GRASS-user] Windows 7 32bit Grass and Python

GRASS GRASS user

Hello,

now I’m getting closer to the problem (but still have no clue how to solve it). Actually grass seems to work - at least the g.list command works fine with python on the windows machine. The problem is the v.in.ogr command which returns -1073741511 as an error code. I tried Grass 6.4.3, Grass 6.4.4 and Grass 7.0 beta the error is the same every time (of course I updated the environmental settings).

Does anybody have an idea how to solve this? That would be great.

Thanks in advance
Caro

Dear Mailing List Readers,

I have problems using grass gis with an external python script on windows 7 32bit. I don’t get any error messages but nothing happens in grass gis. I simply try to import a shapefile and nothing happens (but I have the same problem when trying to list all the existing files in my map set) Everything works fine on OS X so I assume it’s not a matter of wrong python code. When I do that manually in grass everything works fine.

Environmental settings:
GISBASE: C:\Program Files\GRASS GIS 6.4.3
GISRC: C:\Users<myusername>\AppData\Roaming\GRASS6\grassrc6 (this file exists and has the following information:

  • GISDBASE: E:\data\grass_data
  • LOCATION_NAME: Amazon_Brazil
  • MAPSET: Amazon
  • GRASS_GUI: wxpython
    which is the correct grass-location)
    GRASS_SH: C:\Program Files\GRASS GIS 6.4.3\msys\bin\sh.exe
    LD_LIBRARY_PATH: C:\Program Files\GRASS GIS 6.4.3\lib
    PATH: besides other entries C:\Program Files\GRASS GIS 6.4.3\etc;C:\Program Files\GRASS GIS 6.4.3\lib;C:\Program Files\GRASS GIS 6.4.3\bin;C:\Program Files\GRASS GIS 6.4.3\extralib;C:\Program Files\GRASS GIS 6.4.3\msys\bin

import grass.script as grass works. Are there any suggestions what I made wrong/forgot?

Thanks a lot for your help,
Caro

did you see this example?

I tested it successfully on several operating systems (of course
things may always be improved).
