Hi:

I've read some about the pimpl idiom and I know that it provides safe
ABI backward compatibility on shared libraries.

Let's consider the following definitions:

template <class T>
class A
{
public:
A()
{
}

virtual ~A()
{
}

T GetValue() const
{
return mValue;
}

private:
T mValue;
};


class B
{
public:
B(const A<int>& aA)
{
mValue = aA.GetValue();
}

private:
int mValue;
};


How can I provide ABI compatibility in this case, considering that I
cannot use the pimpl idiom in my template class implementation?

Thanks in advance,


Ernesto

Please heeeeelp!!!!!
