I am looking for a way to place a reference to an object on a global list or vector. I think I need something like weak_from_this() in c++17. Unfortunately I need to use c++11:( I would like to do something like:

typedef std::weak_ptr<class Test> WP_Test;
vector<WP_Testl> TestVector;

class Test {
...
   void placeOnVector() { TestVector.push_back(this);}
}

But the compiler is unable to convert "this" to a weak_ptr.

What exactly are you trying to accomplish with this? – merlin2011 Dec 29 '16 at 20:54
You need `std::shared_from_this()`. – Violet Giraffe Dec 29 '16 at 21:31
