[GRASS-dev] Re: [GRASS-windows] wingrass and ArcGIS with Python

I'm using XP BTW.

In my experience Windows often seems to look in windows\system32 for
DLLs rather than where it should...

------- Forwarded message follows -------

I use ArcMap as well - I initially had a problem running either GRASS
or the QGIS GRASS plugin (sorry, I can't remember which) and ended up
copying the pywintypes25.dll version 2.5.212.0 file into the
windows\system32 folder (after renaming the existing version, which
was 2.5.214.0).

Hope this helps someone...

Cheers
Peter

For those who need to run both ArcGIS and GRASS with Python (common
situation in GIS labs), here is the solution for the reported problem
from our technical support:

I found there are different builds of winpython 2.5 . The version
that
works for both is build is 212. I found it here...

Just an update, in case somebody else has a similar problem -
GRASS from OSGeo4W installer runs with nviz on the same VISTA
computers that had the problem below.

But we got an interesting issue with the native installer on our XP
machines in the teaching lab. After a separate Python2.5 install
GRASS wxpython does not run anymore

The error message says:
python.exe
the procedure entry point ?
PyWinObject_AsHABDLE@@YAHPAU_object@@PAPAX@Z
could not be located in the dynamic link library pywintypes25.dll

when we searched for pywintypes25.dll we got
C:\GRASS6-6-SVN\extralib 112KB 1/11/2009
C:\WINDOWS\system32 100KB 9/22/2006
C:\Python25\Lib\site_packages\ 100KB 9/22/2006
C:\GRASS6-6-SVN\Python25\Lib 112KB 1/11/2009

so it looks like the C:\Python25\Lib\site_packages version
is different from the one used by GRASS I asssume that the problem
we have is that GRASS is looking into the wrong pywintypes25.dll. Is
there a solution to this? So far it looks like removing the second
install of Python2.5 is not an option.

thanks,

Helena

Has anybody installed the latest install on VISSTA?
we get only the first two icons and no Tcltk runs (that means no
nviz)
