## 3.2.1 Shared Libraries

You must link the ``.o`' file to produce a shared library. This is done using a special invocation of the Unix loader/linker, ld(1). Unfortunately the invocation differs slightly per system.

On SunOS 4, use

        ld spammodule.o -o spammodule.so

On Solaris 2, use

        ld -G spammodule.o -o spammodule.so

On SGI IRIX 5, use

        ld -shared spammodule.o -o spammodule.so

On other systems, consult the manual page for `ld`(1) to find what flags, if any, must be used.

If your extension module uses system libraries that haven't already been linked with Python (e.g. a windowing system), these must be passed to the `ld` command as ``-l`' options after the ``.o`' file.

The resulting file ``spammodule.so`' must be copied into a directory along the Python module search path.
