Thread: binary trees and protected data

this ones has keep me up all night long

binTNode.h defines the nodes with a constructor that looks something like this.

Code:

public:
binTNode(const T& =T(), binTNode<T>* =0, binTNode<T>* =0);

binTree.h is a friend of binTNode.h and from what i assume should be able to create a new node like so.

Code:

root = new binTnode<T>();

however this error comes up.

Code:

Undefined                       first referenced
 symbol                             in file
binTNode<int>::binTNode[in-charge](int const&, binTNode<int>*, binTNode<int>*)prog3.o
ld: fatal: Symbol referencing errors. No output written to prog3.exe
collect2: ld returned 1 exit status
bash-3.00$

also the bin tree class creates a

Code:

binTNode<T>* root;

pointer without a problem. as for now im fried. any suggestions appreciated.
