Hello all! I have a very strange linking problem... I'm trying to make dynamic library with gcc (MacX gcc 4.0.1). All necessary files has been compiled, but I can▓t link them. I got message: a lot of undefined symbols. For example: Ld : Undefined symbols: ┘ __ZNK6TVect3IdE19CrossProdERKSO_ .. In my project I have a class ⌠Vect3■ and ⌠CrossProd■ method inside it. Command nm vect3.o √a shows that vect3.o contains _ZNK6TVect3IdE19CrossProdERKSO_ . so I don▓t have any ideas what I am doing wrong thanks very much in advance, & best regards Vladimir
