A Cookbook Approach
===================

This manual section was written by Neil Schemenauer
<neil_schemenauer@transcanada.com>.
This section provides a recipe for building a Python extension on
Windows.

Grab the binary installer from <http://www.python.org/> and install
Python.  The binary installer has all of the required header files
except for `config.h'.

Get the source distribution and extract it into a convenient location.
Copy the `config.h' from the `PC/' directory into the `include/'
directory created by the installer.

Create a `Setup' file for your extension module, as described in
chapter Note: Building C and C++ Extensions on UNIX.

Get David Ascher's `compile.py' script from
<http://starship.python.net/crew/da/compile/>.  Run the script to
create Microsoft Visual C++ project files.

Open the DSW file in Visual C++ and select *Build*.

If your module creates a new type, you may have trouble with this line:

         PyObject_HEAD_INIT(&PyType_Type)

Change it to:

         PyObject_HEAD_INIT(NULL)

and add the following to the module initialization function:

         MyObject_Type.ob_type = &PyType_Type;

Refer to section 3 of the  for details on why you must do this.
