Problem configuring Django 1.5b2 with PostGIS 2.0

[Odagi]

Hi, I have been struggling for two days to get a GeoDjango/PostGIS project started and I'll appreciate any help. Thanks

== My project ==

Two virtual machines: 

   Machine 1: Running Django 1.5b2

   Machine 2: Running a geospatial DB server (postgresql-server-dev-9.1, geos-3.3.5, proj-4.8.0, postgis-2.0.2) 

 

== My (wrong??) assumption ==

I don't need to install any geos/postgis library on Machine 1. Please let me know if this is incorrect.

== My Problem ==

When I run:

$  manage.py validate

The result is:

ImproperlyConfigured: Could not import user-defined GEOMETRY_BACKEND "geos".

== Tring to fix this ==

In Machine 1 (where I have my Django application), I include this line in settings.py

GEOS_LIBRARY_PATH = '/opt/geos/lib/libgeos_c.so'

But this path is the location of Geos library in Machine 2 (my DB server).

When I run $ manage.py validate, I get this error:

OSError: /opt/geos/lib/libgeos_c.so: cannot open shared object file: No such file or directory

So, may be I need some Geos libraries in Machine 1 in order to Django communicate with PostGIS, but I'm not sure. 

Any ideas?

I've been experiencing the same issue on OSX 10.8.2.  

$ ./manage.py shell

I've installed Postgresapp (http://postgresapp.com/documentation), which includes Postgres 9.2.2, PostGIS 2.0.2, GEOS 3.3.5, and Proj (not sure of the version, but likely recent).  Note: I also got the same error when installing postgres from homebrew.  Various tutorials indicate that I should set the following in settings.py.  (http://wiki.bitnami.org/Components/Django/GoeDjango_with_PostGIS_Quick_Start_Guide)

GDAL_LIBRARY_PATH="/Applications/Postgres.app/Contents/MacOS/lib/libgdal.dylib"

GEOS_LIBRARY_PATH="/Applications/Postgres.app/Contents/MacOS/lib/libgeos_c.dylib"

GDAL_DATA="/Applications/Postgres.app/Contents/MacOS/share/gdal"

Upon doing so, I get a different error.  

OSError: dlopen(/Applications/Postgres.app/Contents/MacOS/lib/libgeos_c.dylib, 6): Library not loaded: @executable_path/../lib/libgeos-3.3.5.dylib

  Referenced from: /Applications/Postgres.app/Contents/MacOS/lib/libgeos_c.dylib

  Reason: image not found

Below is evidence that the files from PATH statements above do exist.  

$ ls -la /Applications/Postgres.app/Contents/MacOS/lib/libgdal.dylib

My next step is to try to get this running in an Ubuntu virtual machine, but I'd really like to get it work natively in OSX. 

I see that you include a reference to the BitNami documentation, however just to confirm, none of you is working with the BitNami Django Stack, right? In any case the documentation although tested with BitNami should be quite general. Maybe it is a compatibility issue with the different components. Also you mentioned that you'd like to get it working on OS X, have you tried BitNami? It should work, or at least we may be able to provide support if you find any issue.

Best regards,

Victoria.
