Hi all,
I just installed GRASS 6.4.3svn and Python 2.7.3 in Windows 7. I need to
call GRASS functions from outside GRASS. I set the environment variables
given
in the grasswiki except:
GISRC= C:\Documents and settings\user\.grassrc6
Because i cannot find this .grassrc6 in the given path or in any other
path. However with other variables, i tried to use from grass.lib
importgrass in Python27 IDLE. Then it gives an error. I think the
variables are
not set correctly. Could somebody help me to sort this out?
Cheers, Brian.

Hi all,
I have GRASS 6.4.3svn installed in my machine running Windows 7. Also in my
machine i installed Python 2.7.3 for Windows.
Now i need to call GRASS libraries from Python and not within the Python
shell in GRASS GUI itself. I set the environment variables
in the env.bat for this. But connection fails. This is the env.bat i have:
set GISBASE=C:\Program Files\GRASS GIS 6.4.3svn
set HOME=%USERPROFILE%
set LD_LIBRARY_PATH = %GISBASE%\lib
set PATH= %GISBASE%\etc;%PATH%
set PATH=%GISBASE%\Python27;%PATH%
set
PATH=%GISBASE%\lib;%GISBASE%\bin;%GISBASE%\extralib;%GISBASE%\msys\bin;%PATH%
set PATH=C:\Python27;%PATH%
set PYTHONLIB= C:\Python27;%PYTHONLIB%
set PYTHONPATH= %GISBASE%\etc\python;%PYTHONPATH%
rem Environmental variables for GRASS stand-alone installer
set GRASS_WISH=%GISBASE%\extrabin\wish.exe
set GRASS_PYTHON=python
set GRASS_PROJSHARE=%GISBASE%\proj
set GRASS_HTML_BROWSER=explorer
set GRASS_SH=%GISBASE%\msys\bin\sh.exe
set PYTHONHOME=%GISBASE%\Python27
set GDAL_DATA=%GISBASE%\share\gdal
set PROJ_LIB=%GISBASE%\proj
set GEOTIFF_CSV=%GISBASE%\share\epsg_csv
set PATH=%GISBASE%\msys\bin;%PATH%
set PATH=%GISBASE%\extrabin;%GISBASE%\extralib;%PATH%
set PATH=%GISBASE%\tcl-tk\bin;%GISBASE%\sqlite\bin;%GISBASE%\gpsbabel;%PATH%
set PATH=%GISBASE%\bin;%PATH%
rem Path to the python directory --
rem set PYTHONHOME=%GISBASE%\Python27
rem if "x%GRASS_PYTHON%" == "x" set GRASS_PYTHON=python
Can somebody help me in rectifying the problem.
Cheers, Brian.

A suitable should be created the first time you run GRASS.
Alternatively, you can create the file yourself, e.g.:
GISDBASE: /opt/grass-data
LOCATION_NAME: spearfish57
MAPSET: user1
GRASS_DB_ENCODING: ascii

If GISRC doesn't refer to a valid settings file, nothing will work.

Could you explain bit more. You mean without .grasssrc6, it will not work.
I created a new location and mapset as you instructed. But where to
find GRASS_DB_ENCODING: ascii in WinGRASS?

I uninstalled GRASS and then re-installed with spearfish data set with its
spearfish60 location and user1 mapset. Still i cannot see .grassrc6 file
created. Any idea? Please not i use Grass for Windows 7.
