Ok, this works, but anyway, I can't create any instances of the String
class. I tried this:

 #include <iostream>
 #include <String>
 
 int main ()
 {
     String s = "Hello world";
     return 0;
 }

Building the project again produced said error messages:

> undefined reference to 'String::String(char const *)'
> undefined reference to 'String::~String(void)'
> undefined reference to 'String::~String(void)'

Any idea?
