Stop for a moment.
What are you trying to do? Are you writing a kernel module or a user-space
application?

If you're writing a kernel module, you can't use the headers from /usr/include.

If you're writing a user-space application, yuo should use the headers from
/usr/include, not the one from /usr/src/linux-headers-3.13.0.32-generic/include.

Let us know what you're trying to do, what you've got sofar, and what errors
you're getting.

Cheers,
