Note that you don't actually need to compile the examples yourself -
they're built by the xapian-core build system.  But it's a useful small
testcase for problems building with Xapian.

It's better (more portable and more future-proof) to use xapian-config
to get the required flags.  (Also, "-lxapian" is more portable than
"-l xapian" I believe).

This is documented here (and possibly elsewhere too):

http://xapian.org/docs/quickstart.html

For example:

c++ quickstartindex.cc `xapian-config --libs --cxxflags` -o quickstartindex
