Can one of you gurus give me some help please. I am a new programmer so please bear with me. I have a header file called Deck.h and a cpp file called Deck.cpp. In my header file, I have a class called Deck which has prototype function called createPack as one of its member functions. the createPack function is defined in Deck.cpp. I also have a file called PokerEngine.cpp which holds my main function. However, when I create an instance of class Deck and try and call the function createPack, I get undefined reference errors. I have tried using both the "." and "->" operators and I am still getting the errors. I was hoping you guys will be able to help me solve this.
