We can’t really do much based on such error messages - you’ll need to provide the minimal input for reproducing the failure.

Does this line in your code?

using namespace std;

solely based off error provided it looks like multiple defintions of byte and compiler cant decide which one to use you may need be more specific this solely based of what you shared and may not be totallly accurate without knowing more it is hard to say
