General discussions / Re: Need help with ResourceHolder class from book

interesting... I implemented the resource holder class in a file called ResourceHolder.cpp. Why is that turning out to be a problem?

Also I never used a .inl file before, what is that supposed to be? I am really confused why we use inl file and not .cpp file

General discussions / Need help with ResourceHolder class from book

I am going through the SFML game development book and I hit a road block with the resource holder class. I am developing on mac using xCode.

I implemented the class based on the book and I am trying to use it but I get this error

Undefined symbols for architecture x86_64:
  "ResourceHolder<sf::Texture, Textures::ID>::load(Textures::ID, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&)", referenced from:
      _main in main.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)


for the following usage

ResourceHolder<sf::Texture, Textures::ID> textures;
   try
   {
        std::string loc = resourcePath()+"Eagle.png";
        textures.load(Textures::Airplane, loc);
         }
   catch (std::runtime_error& e)
   {
      std::cout << "Exception: " << e.what() << std::endl;
      return 1;
   }

I dont understand why this is happening.
I attached the source files if that helps

Thanks
