Oh, dear - unless the OP know _exactly_ what he's doing he should remove the
distributions devel package to
avoid hard-to-debug problems:

 sudo apt-get purge libxapian-dev

The code post4ed works fine on Debian/testing with the distributed devel
packages as well.

You want to use xapian-config-1.3 here, not xapian-config (which will be the
installed version, not the trunk version you built).

I've just built trunk (on Mac OS, admittedly), and your code compiled and
linked fine, and when run created an empty database as expected.
