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 ...
Best Regards
Martin
