Hello, All !!!

I have template class with only one constructor, which has parameters 
(non-default constructor). I want some object of this class to be a member of 
another class, but not a pointer. Here is an example:

template <class T>
class A
{
public:

  A (int param);
  ...
  int func (void);

};


class B
{

  A<int> a(5);  // this doesn't work. What can I do to make it work, without 
                // changing it to pointer
  ...

Can anyone tell me, why BCW 4.0 Linker doesn't find all non-inline functions of 
class A. I put them all in the same header file as required by "Smart 
Templates" option of BCW 4.0, but I get linker error: "Undfined symbol 
A<int>::func (void) in module ...".

Please e-mail me.
Thanks, beforehand.
Bob.
