## 3.2.2 SGI IRIX 4 Dynamic Loading

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 ``spammodule.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 ``spammodule.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 ``spammodule.ld`'. The file ``spammodule.ld`' is placed in the directory where ``spammodule.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 ``spammodule.libs`' in the same directory as the ``spammodule.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.
