[GRASS-dev] grass.find_program() failing

[Markus Neteler]

Hi,

there are new troubles on Windows8, apparently grass.find_program() is failing.

Regularly ".py" application errors pop up, asking to assign a software to this
extension. The real problem may be different, example:

GRASS 7.0.svn> g.manual.py -i
D2/5: filename = C:/OSGeo4W/apps/grass/grass-7.0.svn/scripts/g.manual.py
D2/5: G_file_name(): path = C:\Users\neteler\Documents\GIS DataBase/nc_spm_08_gr
ass7/user1
D2/5: G_file_name(): path = C:\Users\neteler\Documents\GIS DataBase/nc_spm_08_gr
ass7/user1
FEHLER: Browser <explorer> not found
GRASS 7.0.svn>
GRASS 7.0.svn> which explorer.exe
/c/Windows/system32/explorer.exe

Unrelated or not, a recent commit where my test of finding a GRASS module
in order to not crash otherwise was commented out. Certainly I had tested
it and it used to work.

Related to the python version?

GRASS 7.0.svn> python
Python 2.7.4 (default, Apr  6 2013, 19:54:46) [MSC v.1500 32 bit (Intel)] on win
32
...


GRASS 7.0.svn> which python
/osgeo4w/bin/python.exe

I thought we wanted to use the one from extrabin\ first?

GRASS 7.0.svn> g.version -g
version=7.0.svn
date=2013
revision=56788
build_date=2013-05-19
