multiple definition of template specialization when using different objects

Question

When I use a specialized template in different object files, I get a \"multiple definition\" error when linking. The only solution I found involves using the \"inline\" func

Answer 1

You've explicitly instantiated a template in your header (void Hello::print_hello(T var)). This will create multiple definitions. You can solve it in two ways:

1) Make your instantiation inline.

2) Declare the instantiation in a header and then implement it in a cpp.
