Then when running python the error itself:

Traceback (most recent call last):
  File "classes.py", line 6, in <module>
    t.set("bom dia!")
Boost.Python.ArgumentError: Python argument types in
    World.set(World, str)
did not match C++ signature:
    set(World {lvalue}, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >)

What could be the problem? The interesting is that the build pass 100% with gcc 4.4, but I need to use older versions and it fails for 6,7,8 (which I tried).

Which libraries (full path!) are actually used during compile time and run time? This looks like a mismatch between both.
