Since there are three styles of dynamic loading, there are also three
groups of instructions for building a dynamically loadable module.
Instructions common for all three styles are given first. Assuming
your module is called
spam, the source filename must be
spammodule.c', so the object name is `
module must be written as a normal Python extension module (as
Note that in all cases you will have to create your own Makefile that
compiles your module file(s). This Makefile will have to pass two
`-I' arguments to the C compiler which will make it find the
Python header files. If the Make variable PYTHONTOP points to
the toplevel Python directory, your CFLAGS Make variable should
contain the options `-I$(PYTHONTOP) -I$(PYTHONTOP)/Include'.
(Most header files are in the `
Include' subdirectory, but the
config.h' header lives in the toplevel directory.)
