I'm trying to load a module GDAL into a Python script. The loader/binder that is then called, seems to be generated by SWIG, a project with which I'm unfortunately not familiar. The part of the SWIG generated code that fails on me is as follow:
------ start code snip 1 ------------- # This file was automatically generated by SWIG (http://www.swig.org). # Version 1.3.39 # # Do not make changes to this file unless you know what you are doing--modify # the SWIG interface file instead. from sys import version_info if version_info >= (2,6,0): def swig_import_helper(): from os.path import dirname import imp fp = None try: fp, pathname, description = imp.find_module('_gdal', [dirname(__file__)]) except ImportError: import _gdal return _gdal if fp is not None: print "fp:",fp # <- My code ... print "pn:",pathname # <- My code ... print "de:",description # <- My code ... try: _mod = imp.load_module('_gdal', fp, pathname, description) finally: fp.close() return _mod _gdal = swig_import_helper() del swig_import_helper else: import _gdal del version_info ... <shortened by me> ------ end code snip 1 ------------- I had to redo the indents manually in this mail, I hope I didn't make any mistakes. When I run the script that activates this code, it returns the following: ------ start code snip 2 ------------- fp: <open file 'C:\gdal\bin\gdal\python\osgeo\_gdal.pyd', mode 'rb' at 0x00B35D88> pn: C:\gdal\bin\gdal\python\osgeo\_gdal.pyd de: ('.pyd', 'rb', 3) Traceback (most recent call last): File "C:\Martin\Work_Eclipse\Hilfe\src\check_GDAL.py", line 8, in <module> import gdal File "C:\gdal\bin\gdal\python\osgeo\gdal.py", line 27, in <module> _gdal = swig_import_helper() File "C:\gdal\bin\gdal\python\osgeo\gdal.py", line 26, in swig_import_helper return _mod UnboundLocalError: local variable '_mod' referenced before assignment ------ end code snip 2 ------------- It appears to me that the objects returned by imp.find_module, and printed out as fp:, pn: and de:, are valid. So why is mp.load_module returning what appears to be some flavour of NULL ? I'm using Python version 2.6.6 (r266:84297, Aug 24 2010, 18:46:32) [MSC v.1500 32 bit (Intel)] The GDAL lib is from http://download.osgeo.org/gdal/win32/1.6/gdalwin32exe160.zip All suggestions appreciated ...
