In 'src/_apachemodule.c'.

In 'src/connobject.c'.

Above similarly in other files in the 'src' directory.

These are symbols which are part of Apache and will not be able to be
resolved when compiling mod_python. Normally apxs would tell the
linker to ignore undefined symbols.

Build mod_python on a real UNIX system and watch the build output. You
should see apxs echo back the real compiler command. You just need to
perform the equivalent.

No. The APR is a C library used by Apache in its implementation.

The 'apxs' program is a wrapper script to assist in compiling Apache modules.

The mod_python code uses APR C library. Has because of how Apache also uses it.

Are you truly trying to get mod_python running so you can use
mod_python features, or do you simply want a way of running Python web
applications under Apache and don't care about what the Python web
server API is?
