[Gdal-dev] Ogr and Postgis support

[Lucian Canacheu]

Hi Gus,
In short, no. PostGIS support is disabled by default and if you user the 
binary distro fromgdal.org, that it is a "minimalist" build. Whatever 
Python bindings you add to it you won't get PostGIS support - it is not 
"enabled" in that distribution.
I passed over your messages. I'm using Python bindings for GDAL/OGR/OSR 
with PostGIS and  a couple of years  ago (I think with version 1.3.0 or 
so) I had very  tough times trying to install GDAL binaries into a 
Python "clean" environment. I've tried lots of things and in my opinion 
it was not the right way to do it. So, it may sound scary, you have to 
build yourself most of the needed libraries from sources (in this order) 
- proj4.5, libecw3.3, install Postgresql and PostGIS, geos2.2.3. The 
GDAL compilation works flawlessly on Win32 with VS 2003 and on Linux 
with compiler gcc 3.4.6.
I used these setup procedures ever since GDAL v 1.3.x. Give it a try and 
you'll see it works.
If you work this way, you'll have the chance to enable PostGIS 
extensions on Win32 platform. These are disabled by default:

# PostGIS Libraries
#PG_INC_DIR = n:\pkg\libpq_win32\include
#PG_LIB = n:\pkg\libpq_win32\lib\libpqdll.lib wsock32.lib
in the nmake.opt file

On Linux, you have to do something like this:
./configure --with-python=/opt/python-2.4.4/bin/python 
--with-postgres-includes=/usr/include/pgsql 
--with-postgres-libraries=/usr/lib

in order to enable PostGIS.

Cheers,
Lucian
