This works just fine:

//----------------------------------------------------------------------
#include <iostream>

namespace geometry
{
    class A
    {
     public:
        int value() const { return 5; }
    };

    inline std::ostream& operator<<(std::ostream& os, const A& obj)
    {
        os << obj.value();
        return os;
    }
}

int main()
{
    geometry::A a;
    std::cout << a << std::endl;
}
//----------------------------------------------------------------------
