How do I call ::std::make_shared on a class with only protected or private constructors?

Question

I have this code that doesn\'t work, but I think the intent is clear:

testmakeshared.cpp

#include 

class A {
 public:
   stat

You can use this:

class CVal
{
    friend std::shared_ptr;
    friend std::_Ref_count;
public:
    static shared_ptr create()
    {
        shared_ptr ret_sCVal(new CVal());
        return ret_sCVal;
    }

protected:
    CVal() {};
    ~CVal() {};
};
