Verify at compile time that objects are created as shared_ptr

There are classes that I write (often as part of boost::asio) whose objects depend on being wrapped in a shared_ptr because they use shared_from_this(). Is there a way to prevent an object from being compiled if it's not instantiated in a shared_ptr?

So, what I'm looking for:

std::shared_ptr<MyClass> a = std::make_shared<MyClass>(); // should compile fine
std::unique_ptr<MyClass> a = std::make_unique<MyClass>(); // compile error
MyClass a; // compile error
