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.

Usually, in C++, you should put or include the implementation code for the template class into the 'same' header file. That is the way you should do in BC, though some C++ compiler can handle something like 'temp.h' and 'temp.c' and then produce 'temp.o'.
