i'm tring to utilize a python function iside the grass environment,

If "make clean" and rebuilding doesn't fix it, then it sounds like you
have more than one version of GRASS on your system, and it's picking
up the wrong libraries.
Yes it is, i tried make clean && make distclean,
i also tried on a fresh svn download.
I've installed on my system different grass versions :
grass64 (binary verion)
grass65 , grass70 (from svn)
outside a running GRASS, it works from python. From python started
inside a GRASS shell, it doesn't work.
That sounds like multiple versions.
How to avoid this problem?
has my system hardcoded some where the existence oh other grss
version? can i masherate/eliminate something?
the function i'm using is prety simple :
###
import os
import subprocess
def OssimImg2rr(img1):
os.environ['DYLD_FRAMEWORK_PATH'] = '/var/tmp/XcodeBuilds/
Release'
os.environ['OSSIM_PREFS_FILE'] = '/Users/sasha/ossim_preferences'
output = subprocess.Popen(['/var/tmp/XcodeBuilds/Release/
img2rr' ,str(img1)],stdout=subprocess.PIPE).communicate()[0]
Leave os.environ alone; create a new environment dictionary and pass
that to subprocess.Popen(), e.g.:
myenv = os.environ.copy()
myenv['DYLD_FRAMEWORK_PATH'] = '/var/tmp/XcodeBuilds/Release'
myenv['OSSIM_PREFS_FILE'] = '/Users/sasha/ossim_preferences'
output = subprocess.Popen(..., env = myenv).communicate()[0]
This isn't related to this specific problem, though, just general
Python coding advice.
Thanks! i'm self.teached so advice like these ere for me a great help
i hope i modified it well :
def OssimImg2rr(img1):
myenv = os.environ.copy()
myenv['DYLD_FRAMEWORK_PATH'] = '/var/tmp/XcodeBuilds/Release'
myenv['OSSIM_PREFS_FILE'] = '/Users/sasha/ossim_preferences'
output = subprocess.Popen(['/var/tmp/XcodeBuilds/Release/
img2rr' ,str(img1)], stdout=subprocess.PIPE, env = myenv).communicate()
