[GRASS-dev] Calling GRASS from outside: cannot open shared object file

[Markus Neteler]

Hi,

I tried my current start-python-and-create-a-location script on Windows.
The location is generated but then a call of the scripting library fails
with a gettext error (I print the os.environment to understand more but no
idea):


Python 2.7.6 (default, Nov 10 2013, 19:24:18) [MSC v.1500 32 bit (Intel)]
on win32
Type "help", "copyright", "credits" or "license" for more information.

Imported NumPy 1.8.0, SciPy 0.13.3, Matplotlib 1.3.1
runfile('C:/Users/VPCF2/Desktop/STEM/grass7_python/start_grass7_create_new_location_ADVANCED
(1).py', wdir=r'C:/Users/VPCF2/Desktop/STEM/grass7_python')
+ guidata 1.6.1, guiqwt 2.3.1
Type "scientific" for more details.

Any suggestions? This is using OSGeo4W 32bit.
