Hi Maria,
	as for most Linux programs, you also have to run 'make install' after
'make'. If you have administrator privileges on your computer, you can
run 'make install' with your current configuration (or 'sudo make
install' if you need to get the required privileges.) After that, 

g++ filename.cpp -o filename -lQuantLib

should work. Otherwise, you can install in your user space: run first

./configure --with-boost-include=/home/maria/Boost/boost_1_35_0
--prefix=/home/maria/

(on one line, of course) and then 'make install'. The installation will
create a few directories (include, lib, bin...) in your home directory;
if you want them somewhere else, just provide a different prefix to
configure. After this, you can use

g++ filename.cpp -o filename -l/home/maria/include -L/home/maria/lib
-lQuantLib

(of course, replace /home/maria with the correct prefix if you chose a
different one.)
