Getting GIS Working - possible kernel32 problem

[Robin St.Clair]

Hi

I am working with a project started by somebody else.It uses GIS. I have installed GDAL and OpenGeo4W, plus the C++ runtime.

I have the following included in the path

• C:\Python27\;C:\Python27\Scripts;C:\Python27\Tools\Scripts\;C:\Python27\lib\site-packages;C:\gdalwin32-1.6\bin;C:\usr\bin;C:\Program Files\GDAL;C:\ms4w\Apache\cgi-bin;C:\OSGeo4W\bin;
  

and the following environment variables are set

• GDAL_DATA = %OSGEO4W_ROOT%\share\gdal
  
• GDAL_DRIVER_PATH = C:\Program Files\GDAL\gdalplugins
  
• GEOS_LIBRARY_PATH=C:\OSGeo4W\lib
  
• OSGEO4W_ROOT=C:\OSGeo4w
  
• PROJ_LIB=%OSGEO4W_ROOT%\share\proj
  
• PYTHON_ROOT=C:\Python27
  

Originally this development started on a linux box, I am using Vista SP2.

My database is PostgreSQL 9.3, I have installed the PostGIS options and set up a normal and a GIS database.

When I start runserver through Pycharm, I get the errors at the bottom of this post.

It appears, and I might be wrong as I'm not mega experienced with this, that django/python can't find kernell32. This is used by the C library.

Here is what I have found from thr debugger

self = unable to get repr for class <class 'ctypes.WinDLL'

handle=None

mode=0

name='kernel32'

Funcptr = <class 'ctypes.WinDLL'>

Can somebody please point me in the correct direction, I'm banging my head

Thanks

Robin

Can you try running 'python.exe manage.py runserver' outside of
PyCharm, i.e. in the Command Prompt/PowerShell?

I've got a similar setup, although on Windows 7, and it works. Instead
of setting environment variables, I added the following parameters
into my settings.py to indicate the location of the GEOS DLLs -

GEOS_LIBRARY_PATH = os.sep.join((PROJECT_PATH, '..', 'Scripts', 'geos_c.dll'))
GDAL_LIBRARY_PATH = os.sep.join((PROJECT_PATH, '..', 'Scripts', 'gdal110.dll'))

Find those two files on your system (I didn't install GDAL or OSGeo4W
so I can't tell you where) and set the above parameters in settings.py
and see how you go.
