Cannot access private member in singleton class destructor

Question

I\'m trying to implement this singleton class. But I encountered this error:

\'Singleton::~Singleton\': cannot access private member declared in class \'Singleton\'

Answer 1

Personally i haven't put destructors in my singletons unless i am using a template singleton class, but then i make them protected.

template
class Singleton
{
public:
    static T &GetInstance( void )
    {
        static T obj;
        return obj;
    }

    static T *GetInstancePtr( void )
    {
        return &(GetInstance());
    }

protected:
    virtual ~Singleton(){};
    Singleton(){};

};

then write my class as

class LogWriter : public Singleton
{
friend class Singleton;
}
