 <H1>SWIG Python Examples</H1>

 <p>
 The following examples illustrate the use of SWIG with Python.

 <ul>
 <li><a href="simple/index.html">simple</a>.  A minimal example showing how SWIG can
 be used to wrap a C function, a global variable, and a constant.
 <li><a href="constants/index.html">constants</a>.  This shows how preprocessor macros and
 certain C declarations are turned into constants.
 <li><a href="variables/index.html">variables</a>. An example showing how to access C global variables from Python.
 <li><a href="value/index.html">value</a>. How to pass and return structures by value.
 <li><a href="class/index.html">class</a>. Wrapping a simple C++ class.
 <li><a href="reference/index.html">reference</a>. C++ references.
 <li><a href="pointer/index.html">pointer</a>. Simple pointer handling.
 <li><a href="funcptr/index.html">funcptr</a>. Pointers to functions.
 </ul>

 <h2>Compilation Issues</h2>

 <ul>
 <li>To create a Python extension, SWIG is run with the following options:

 <blockquote>
 <pre>
 % swig -python interface.i
 </pre>
 </blockquote>

 <li>
 Please see the <a href="../../Doc/Manual/Windows.html">Windows</a> page in the main manual for information on using the examples on Windows. <p>
 </li>

 <li>On Unix the compilation of examples is done using the file <tt>Example/Makefile</tt>.  This
 makefile performs a manual module compilation which is platform specific.  Typically,
 the steps look like this (Linux):

 <blockquote>
 <pre>
 % swig -python interface.i
 % gcc -fpic -c interface_wrap.c -I/usr/local/include/python1.5
 % gcc -shared interface_wrap.o $(OBJS) -o interfacemodule.so
 % python
 Python 1.5.2 (#3, Oct  9 1999, 22:09:34)  [GCC 2.95.1 19990816 (release)] on linux2
 Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
 &gt;&gt;&gt; import interface
 &gt;&gt;&gt; interface.blah(...)
 ...
 </pre>
 </blockquote>

 <li>The politically "correct" way to compile a Python extension is to follow the steps
 described at <a href="http://www.python.org/doc/current/ext/building-on-unix.html">www.python.org</a>
 or in the most excellent (and shamelessly plugged) <a href="http://islab.cs.uchicago.edu/python">Python Essential Reference</a>:

 <p>
 <ol>
 <li>Create a file called <tt>Setup</tt> that looks like the following where $(SRCS) is filled
 in with any other source files you need to build the extension:

 <blockquote>
 <pre>
 *shared*
 interface interface_wrap.c $(SRCS)
 </pre>
 </blockquote>
 <li>Copy the file <tt>Makefile.pre.in</tt> from the Python distribution.  Usually it's located
 in the directory <tt>/usr/local/lib/python1.5/config</tt> on a Unix machine.

 <p>
 <li>Type the following to build the extension:

 <blockquote>
 <pre>
 % make -f Makefile.pre.in boot
 % make
 </pre>
 </blockquote>
 <li> And that's it.   If you are preparing an extension for distribution, you may want
 to look at the <a href="http://www.python.org/sigs/distutils-sig/">distutils</a>.
 </ol>
 </ul>

 <h2>Compatibility</h2>

 The examples have been extensively tested on the following platforms:

 <ul>
 <li>Linux
 <li>Solaris
 </ul>

 All of the examples were last tested with the following configuration (9/1/2000):

 <ul>
 <li>Sparc Solaris 2.8.
 <li>gcc-2.95.2
 <li>Python 1.6b1.
 </ul>
