These errors (at least the first few, I didn't check all of them) comes 
from lines where Glib::ustring is mentioned. Some of the libxml++ header 
files include <glibmm/ustring.h>, and without `pkg-config --cflags 
--libs libxml++-2.6` g++ can't find that file.

What makes you think that you should be able to compile and link without 
`pkg-config --cflags --libs libxml++-2.6`? Is there any documentation 
that says so? In that case, it's wrong. Or what's the problem with 
including `pkg-config --cflags --libs libxml++-2.6` in the g++ command? 
You can store it in a makefile or a shell script. You don't have to 
write it every time you compile your program.
