bf IMPORTANT: You must compile your extension module with the additional C flag `-G0' (or `-G 0'). This instruct the assembler to generate position-independent code.
You don't need to link the resulting `foomodule.o' file; just
copy it into a directory along the Python module search path.
The first time your extension is loaded, it takes some extra time and
a few messages may be printed. This creates a file
`foomodule.ld' which is an image that can be loaded quickly into
the Python interpreter process. When a new Python interpreter is
installed, the dl package detects this and rebuilds
`foomodule.ld'. The file `foomodule.ld' is placed in the
directory where `foomodule.o' was found, unless this directory is
unwritable; in that case it is placed in a temporary
directory.
If your extension modules uses additional system libraries, you must
create a file `foomodule.libs' in the same directory as the
`foomodule.o'. This file should contain one or more lines with
whitespace-separated options that will be passed to the linker -
normally only `-l' options or absolute pathnames of libraries
(`.a' files) should be used.
