Error in the program

#ifndef BASE_H
#define BASE_H
class Base
{
public:
    int m_nValue;

    Base(int nValue=0)
        : m_nValue(nValue)
    {
    std::cout << "Base" << std::endl;
    }
};
#endif



#ifndef DERIVED_H
#define DERIVED_H
#include "Base.h"
class Derived: public Base
{
public:
    double m_dValue;

    Derived(double dValue=0.0)
        : m_dValue(dValue)
    {
    std::cout << "derived se" << std::endl;
    }
    friend std::ostream & operator << (std::ostream& os, const Derived &d);
    friend std::istream & operator >>(std::istream& is,  Derived &d);
};
inline std::ostream& operator << (std::ostream& os, const Derived &d)

    return os << d.m_dValue;
}
inline std::istream & operator >>(std::istream& is,  Derived &d)

}

#endif



#include <iostream>
#include "Derived.h"
using namespace std;



int main()
{
    Derived d(4.5);
    cout << d;

}

And the error is

Can anybody throw a light on the reason of this error message?

Builds (and runs) fine on my system (using gcc V4.7.3 on Ubuntu 12.04).

It's actually quite an interesting thing. Relatively speaking.

You have this

gcc -std=c++11 -std=c++0x -W -Wall tt1.cpp

but should it be

g++ -std=c++11 -std=c++0x -W -Wall tt1.cpp
