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 on Dynamic Loading for more info 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, add a line to the file
`Modules/Setup' 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 rebuilt the `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 `Setup' file as well, for instance:
spam spammodule.o -lX11
