1.5 Compilation and Linkage
         
</H1>

<P>
There are two more things to do before you can use your new extension:
compiling and linking it with the Python system.  If you use dynamic
loading, the details depend on the style of dynamic loading your
system uses; see the chapter ``Dynamic Loading'' for more information
about this.

<P>
If you can't use dynamic loading, or if you want to make your module a
permanent part of the Python interpreter, you will have to change the
configuration setup and rebuild the interpreter.  Luckily, this is
very simple: just place your file (<tt class=file>spammodule.c</tt> for example) in
the <tt class=file>Modules/</tt> directory of an unpacked source distribution, add
a line to the file <tt class=file>Modules/Setup.local</tt> describing your file:

<P>
<dl><dd><pre class=verbatim>
spam spammodule.o
</pre></dl>

<P>
and rebuild the interpreter by running <b class=program>make</b> in the toplevel
directory.  You can also run <b class=program>make</b> in the <tt class=file>Modules/</tt>
subdirectory, but then you must first rebuild <tt class=file>Makefile</tt>
there by running `<b class=program>make</b> Makefile'.  (This is necessary each
time you change the <tt class=file>Setup</tt> file.)

<P>
If your module requires additional libraries to link with, these can
be listed on the line in the configuration file as well, for instance:

<P>
<dl><dd><pre class=verbatim>
spam spammodule.o -lX11
</pre></dl>
