#must look like something like this:

#	[build_ext]
#	#define=
#	include_dirs=/usr/local/include
#	library_dirs=/usr/local/lib
#	libraries=sqlite3
#	#define=SQLITE_OMIT_LOAD_EXTENSION

sudo python setup.py install

# now run your Django project by
python manage.py runserver

I try follow this steps, but now I'm getting this error:

OSError: /usr/lib/x86_64-linux-gnu/libspatialite.so.7: undefined symbol: sqlite3_create_function_v2

Can you help me with this? I need to install spatialite like dependency in my django project.
