[gdal-dev] Python Bindings

[Jeff Hamann]

I've built GDAL/OGR (1.7.2) with the following ./configure options 

$ ./configure \
 CC="gcc -arch i386" \
 CXX="g++ -arch i386" \
 OBJC="gcc -arch i386" \
 F77="gfortran -arch i386" \
 FC="gfortran -arch i386" \
  --with-pg=/usr/local/pgsql/bin/pg_config \
  --without-macosx-framework \
  --without-sqlite3 \
  --with-python

Even though I run on a mac, I really don't want to build with the framework. 

When I attempt to run a simple Python script:

#! /usr/bin/env python
from osgeo import gdal

I get the following:

Jeff-Hamanns-MacBook-Pro:scripts hamannj$ python pytest.py 
Traceback (most recent call last):

I know *nothing* about python. 

There are a bunch of these statements:

from osgeo import gdal
from osgeo import osr
import osgeo.gdalconst as gdalc
from optparse import OptionParser, OptionGroup
import binascii
import glob
import math
import numpy
import os
import sys

in the gdal2wktraster.py file that I eventually want to run, but I don't know enough about python to diagnose, debug, and correct these problems. 

Is this a python binding problem with gdal/ogr? 

When I ./configured gdal/ogr: I got the following results:
