Re: Multiple inheritance/interface delegate through template function not working

The code must be:

#include <iostream>

class PureVirtual
{
public:
    virtual void VirtFun() = 0;
};

template <long I, class T>
class TPureVirtual : public PureVirtual
{
public:
        virtual void VirtFun()
        {
                // 1.
                static_cast<T&>(*this).Done(I);
                // 2.
                static_cast<T&>(*this).template TDone<I>();
        }
};

class ImplVirtual : public TPureVirtual<1, ImplVirtual>,
                                        public TPureVirtual<2,
ImplVirtual>
{
public:

        void
    Done(long I)
    {
                std::cout << "ImplVirtual<" << I << ">::Done" <<
std::endl;
    }

        template <long I> void
    TDone()
    {
                std::cout << "ImplVirtual<" << I << ">::TDone" <<
std::endl;
    }

};

//Main should not have explicit linkage specification
int main()
{
        ImplVirtual impl;

        TPureVirtual<1, ImplVirtual> *pv1 = &impl;//no need to do
explicit cast here
        pv1->VirtFun();
        TPureVirtual<2, ImplVirtual> *pv2 = &impl;//no need to do
explicit cast here
        pv2->VirtFun();

        return 0;
}
