Here is a little howto to build gdal 1.4.0 with MSVC Toolkit 2003,
latest GEOS 3 lib and Python NG bindings.

 

The built library is available  here .

 

The patch mentionned in the article is availabe here .

Latest svn release (3.0.0RC1 17/01/2007) of GEOS must be modified in
order to be compiled :

 

• capi/geos_c.h.in -> capi/geos_c.h

• source\headers\geos\version.h.in --> source\headers\geos\version.h

• source\headers\geos\platform.h.vc --> source\headers\geos\platform.h

In the files geos_c.h and version.h, update the @VERSION_MAJOR@,
@VERSION_MINOR@, @VERSION_PATCH@, @VERSION@ to the right values (3, 0, 0
and 3.0.0 in my case).

According to some info, I haven't updated @JTS_PORT@, nor the
@CAPI_VERSION_MAJOR@, etc.

Then :

GEOS_SOURCE\source\>nmake -f makefile.vc

There is no install target in the makefile, so you should copy the
produced dll into a directory in yout PATH (or update your path ...).

Update the nmake.opt to match your installation (GDAL_HOME, GEOS libs,
Python install, etc),

GDAL_SOURCE\>nmake -f makefile.vc

Install the files into your GDAL_HOME

GDAL_SOURCE\>nmake -f makefile.vc install

After having built and installed gdal, build the new swig interface
going in the swig directory :

GDAL_SOURCE\swig\>nmake -f makefile.vc python

! Your python installation must have a numpy version > 1 (I've added a
test in the GDAL_SOURCE\swig\python\setup.py file)

I have modified the GDAL_SOURCE\swig\makefile.vc in order to install the
python modules after having them built (see the attached patch). This
will install the modules into your Python installation directory (C:
\Python24\Lib\site-packages\ on my computer). Otherwise your PYTHONPATH must point to the pymod directory.

 

Then, after having updated the PATH environment variables so that it
includes $GDAL_HOME\bin\ (path to the gdal14.dll), you can use GDAL 1.4
with it's new-generation python interface.
