TPythia8.h: No such file or directory

I have installed ROOT and Pythia8 from the Ubuntu software repositories.
When I want to compile occur error:

$ g++ cut_test.cxx `root-config --libs --cflags` -o cut_test
cut_test.cxx:9:22: fatal error: TPythia8.h: No such file or directory
 #include "TPythia8.h"
                      ^
compilation terminated.

You’re possibly missing some packages, e.g. “root-plugin-montecarlo-pythia8” and/or “pythia8-root-interface”.

I have this packages.
