APstring

I have apstring.c and apstring.h, and I have the header files in struct where my name and profession is for my RPG that I'm making. But when I try to compile (no work with the apstring stuff yet), I get this error:

Code:

---

main.obj : error LNK2001: unresolved external symbol "public: __thiscall apstring::~apstring(void)" (??1apstring@@QAE@XZ)
main.obj : error LNK2001: unresolved external symbol "public: __thiscall apstring::apstring(void)" (??0apstring@@QAE@XZ)

---

I've spent about 15-25 mins trying to fix this, and spent another 10 mins searching around....I would greatly appreciate any help that anyone can offer me.

Are the files included in the project?

No, there in the include folder *I'm also using VC++ 6.0*

The .cpp file must be included inside the project, or you can edit the apstring.h to #include the apstring.cpp, but that's pretty ugly and hackish :).
