[GRASS-dev] Re: [GRASS-windows] compiling WINGrass Python Scripts - ExpatError

[Johannes Radinger]

Hello,

I tried no to put 'set PYTHONPATH=%GISBASE%\etc\python;%PYTHONPATH%'
into the env.bat file of my selfcompiled GRASS6.5SVN on Windows.
Anyway it took me a while to get the 'real' correct line I think (as mentioned in the wiki)

In the env.bat file (C:\\OSGeo4W\apps\grass\grass-6.5.svn\etc\env.bat)
there are now following lines:

set GISBASE=%OSGEO4W_ROOT%\apps\grass\grass-6.5.svn
set GRASS_SH=%OSGEO4W_ROOT%\apps\msys\bin\sh.exe
set GRASS_WISH=%OSGEO4W_ROOT%\bin\wish.exe
set GRASS_PYTHON=%OSGEO4W_ROOT%\bin\python.exe
set GRASS_PROJSHARE=%OSGEO4W_ROOT%\share\proj
set GRASS_HTML_BROWSER=explorer
set PATH=%OSGEO4W_ROOT%\apps\grass\grass-6.5.svn\bin;%OSGEO4W_ROOT%\apps\grass\grass-6.5.svn\lib;%PATH%
set PYTHONPATH=%OSGEO4W_ROOT%\apps\Python25;%PYTHONPATH%

is that correct so far??? 
It seems that now a least the grass.script is found...but I still get
an erro when I want to call a python module/add on/script (with --help) from the GRASS commands console in the GRASS GUI:

Is there anything more I can check? It seems that grass.script needs
a via subprocess a module called collections which isn't included in the python25 from the osgeo4w framework... do I understand that error correctly?

Just another question: Is it possible to use also my "own" python windows installation. Like I want to call my own add-on/script which includes g.parser and is compiled with the source. This script needs to load other pyhton modules which don't come with the osgeo-python. I script of this type is working on my Mac without any problems...hopefully it will also work on windows...
                   
Thank you,

Johannes
