The ODR rule works exactly the same for static libraries as it does for object files, but things aren't so clear when we build our code with SHARED libraries. A linker will allow duplicated symbols here. In the following example, we'll create two shared libraries, A and B, with one duplicated() function and two unique a() and b() functions:
