Hi,
I get it running (on Linux, winGRASS untested) when setting up the
LD_LIBRARY_PATH at system level:
su
echo "`grass71 --config path`/lib" > /etc/ld.so.conf.d/grass71.conf
ldconfig
exit
# run as normal user:
python python_test_ctypes.py
...
precip_annual@user1
/home/neteler/grassdata/nc_spm_08_grass7
Works.
The issue is that we cannot easily enforce the users to add a file in
/etc/ld.so.conf.d/ since it requires admin rights.
Suggestions?

import os
import sys

grass7bin = 'grass71'
# FIRST TIME PREPARATION
#sudo echo "`grass71 --config path`/lib" > /etc/ld.so.conf.d/grass71.conf ; ldconfig

# query GRASS 7 itself for its GISBASE

startcmd = grass7bin + ' --config path'
p = subprocess.Popen(startcmd, shell=True,
stdout=subprocess.PIPE, stderr=subprocess.PIPE)
out, err = p.communicate()
