[GRASS-dev] re: python grass problems on OSX (Incompatible library version for module)

[massimo di stefano]

I'm tring to debug these weird situation ....

assured that only osx is affcted by these problems, (on linux i've no  
problems)

i tried to run the img2rr executable, using python inside a grass  
session (6.4, 6.5 & 7.0)
using a grass raster file it do not works, while using a simple geotif  
instead of a grass file ... it works :


GRASS 6.4.0RC3 (spearfish60):~ > export OSSIM_PREFS_FILE=/Users/sasha/ 
ossim_preferences
GRASS 6.4.0RC3 (spearfish60):~ > ipythonPython 2.5.1 (r251:54863, Jan  
13 2009, 10:26:13)

^^^ Using a GTiff file


so ... the problem is in :
export OSSIM_PREFS_FILE=/Users/sasha/ossim_preferences

inside grass - python it do not works as aspected.


here other debug :

start a new grass shell, omitting the step :

export OSSIM_PREFS_FILE=/Users/sasha/ossim_preferences


GRASS 6.4.0RC3 (spearfish60):~ > ipython
..
...
In [1]: import os
In [2]: import subprocess

Shared/grassdata/spearfish60/PERMANENT/cellhd/geology', shell=True)
MPI running with 1 processors...
WARNING: Unable to open image file /Users/Shared/grassdata/spearfish60/

^^^ the same message come up in bash too, if i don't export the  
"OSSIM_PREFS_FILE=/Users/sasha/ossim_preferences"


adding the export line :

In [4]: os.environ['OSSIM_PREFS_FILE'] = '/Users/sasha/ 
ossim_preferences'

In [5]: subprocess.call('/var/tmp/XcodeBuilds/Release/img2rr /Users/ 
Shared/grassdata/spearfish60/PERMANENT/cellhd/geology', shell=True)
MPI running with 1 processors...
ERROR: Incompatible library version for module
Out[5]: 1

it give me the lib error




but ... the libs are not broken!
beacouse inside a standard python it works :

In [1]: import os

In [2]: import subprocess

In [3]: os.environ['OSSIM_PREFS_FILE'] = '/Users/sasha/ 
ossim_preferences'
In [4]: subprocess.call('/var/tmp/XcodeBuilds/Release/img2rr /Users/ 
Shared/grassdata/spearfish60/PERMANENT/cellhd/geology', shell=True)

doing a more depth debug ....
i tried to wrote a script in grass, to avoid use of python,  that is :


####################################
#!/bin/sh
#% Module
#%  description: Calculates Optimum-Index-Factor table for LANDSAT TM  
bands 1-5, & 7
#%  keywords: raster, imagery, statistics
#% End
#% option
#% key: image1
#% type: string
#% gisprompt: old,cell,raster
#% description: LANDSAT TM band 1.
#% required : yes
#% end

if  [ -z "$GISBASE" ]
then
	echo "You must be in GRASS GIS to run this program" >&2
	exit 1
fi

if   [ "$1" != "@ARGS_PARSED@" ]
then
	exec g.parser "$0" "$@"
fi

eval `g.gisenv`
: ${GISBASE?} ${GISDBASE?} ${LOCATION_NAME?} ${MAPSET?}
LOCATION=$GISDBASE/$LOCATION_NAME/$MAPSET

export OSSIM_PREFS_FILE=/Users/sasha/ossim_preferences
/var/tmp/XcodeBuilds/Release/img2rr $LOCATION/cellhd/$GIS_OPT_IMAGE1

####################################


unlucky i get the same error :

GRASS 6.4.0RC3 (spearfish60):~ > i.img2rr image1=geology
MPI running with 1 processors...
ERROR: Incompatible library version for module



... at least i eliminate the python ... as the cause of my problrems :-(

please people help mde to know what is the problem, if exists a wok- 
around ... or do you know a solution ...

but ... maybe a know the answer, is these problem generated by a  
difference in the libs that i'm using to build ossim and grass ???

for the build i'm using the exactly same gdal.framework ... but my  
think is about tiff/libgeotiff files ... maybe they can be the cause?


any suggestion is really  welcome!


Have you any ideas about these weird behavioure, why it happens, how  
to debug it ?

please tell me if you need better description, or log.


Thanks!!!
