[Gdal-dev] Built gdal with python support - error

I recently built gdal's python support on OS X 10.3 (with the OS  
supplied Python 2.3) by relying on the apple compiler's support for  
frameworks.

After you configure --without-python, edit the python section of  
GDALMake.opt like so:

PYTHON_INCLUDES =  
-I/System/Library/Frameworks/Python.framework/Versions/2.3/include/ 
python2.3
PYTHON_LIBS = -framework Python
PYTHON_CFLAGS =
PYTHON = yes

and run make. The only other problem seems to be that the shared  
library is not created as a bundle so after everything is built, you  
need to build the python module using something like:

  g++ -bundle -flat_namespace gdal_wrap.o numpydataset.o gdalnumeric.o  
-L.. -lgdal -framework Python -ljpeg -lpng -lz -ldl -o _gdalmodule.so

If you run otool -L on the .so file, you can verify that it is using  
the appropriate libraries.
