Hi Ben,
I didn't find my error, so i decide to proceed with another method:
I use a project which works.
I create the file : rfid_file.cc and rfid_file.h
I modify the file rfid.i
I use the command: ./boostrap
./configure
./make
./make configure
And i have no errors :-),
But i have an error after that, when i import my block in my file .py.
*
Traceback (most recent call last):

Btw, thank you a lot for your help!
