Problem with link

Wr3ckinCr3w (9)
I'm trying to work with Link Lists and I keep getting a link error when I try and create an instance of the class. I've been working on figuring out this problem for the better part of the weekend. I've seen solutions on downloading an SDK and adding some linkers, but non of those have worked. Thanks in advance.

The problem is when I declare this:
BlackJack BJ;

Here are the errors:
Error 1 error LNK2019: unresolved external symbol "public: __thiscall BlackJack::~BlackJack(void)" (??1BlackJack@@QAE@XZ) referenced in function _main Main.obj BlackJackClass

Error 2 fatal error LNK1120: 1 unresolved externals C:\Documents and Settings\Desktop\BlackJackClass\Debug\BlackJackClass.exe 1 BlackJackClass
