Compilation and Linkage
=======================

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 chapters about building extension modules on UNIX
(chapter Note: Building C and C++ Extensions on UNIX) and Windows
(chapter Note: Building C and C++ Extensions on Windows) for more
information about this.

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 (`spammodule.c' for example) in the
`Modules/' directory of an unpacked source distribution, add a line to
the file `Modules/Setup.local' describing your file:

     spam spammodule.o

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

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

     spam spammodule.o -lX11
