My CINT script is run, but when I try compile I have this error:

There is something fishy with your installation of Pythia8. You have Pythia header files in /usr/include/Pythia8 and in /usr/include/Pythia8/Pythia8 that are getting mixed. Probably from different versions.
I removed /usr/include/Pythia8/Pythia8 and I have error :

Yes. You need to link to the pythia library now by adding -lpythia8 in tour command.
I added -lpythia8
$ g++ cut_test.cxx `root-config --libs --cflags` -lpythia8 -o cut_test22

Sorry, I meant -lEGPythia8, which is the ROOT library implementing TPythia8::…
another problem:
$ g++ cut_test.cxx `root-config --libs --cflags` -lEGPythia8 -o cut_test22
/usr/bin/ld: cannot find -lEGPythia8
collect2: error: ld returned 1 exit status

What is output of " root-config --libs --cflags " ?
$ root-config --libs --cflags
-L/usr/lib/x86_64-linux-gnu -lCore -lCint -lRIO -lNet -lHist -lGraf -lGraf3d -lGpad -lTree -lRint -lPostscript -lMatrix -lPhysics -lMathCore -lThread -pthread -lm -ldl -rdynamic -pthread -m64 -I/usr/include/root

How did you install ROOT in your system? Are the ROOT libraries in /usr/lib/x86_64-linux-gnu? Did you enable pythia8?
I installed from Ubuntu repositories. (sudo apt-get install packages)

As I said the TPythia8 class is implemented in library libEGPythia8.so . If this library is not in your installation you will need to build from sources.
My CINT script is loaded in such a way:
gSystem->Load("/usr/lib/x86_64-linux-gnu/libpythia8");
gSystem->Load("libEG");
gSystem->Load("libEGPythia8");
Assuming that you have “root-plugin-montecarlo-pythia8” and “pythia8-root-interface” packages installed, try:
I try:
g++ cut_test.cxx `root-config --libs --cflags` -L/usr/lib/x86_64-linux-gnu/root5.34 -o cut_test22

and where’s the library name?
