[C++] Move assignment operator and constant qualifier

[mstanichenko]

Hello,

I've been playing with simple-binary-encoding and CME templates and came across an issue which I don't know how to resolve. I am not able to compile generated stubs because they have a constant parameter for default move assignment operator. Below is a model example which illustrates a problem:

class A {
public:
  A(){};
  ~A(){};

  A(A&& other) = default;
  A& operator=(const A&& other) = default;
};

int main()
{
  A a;

  return 0;
}

$ g++ -std=c++11 a.cc
a.cc:7:6: error: defaulted declaration ‘A& A::operator=(const A&&)’
   A& operator=(const A&& other) = default;
      ^
a.cc:7:6: error: does not match expected signature ‘A& A::operator=(A&&)’

For example, this issue occurs if one generates stubs based on CME template file and tries to include generated MessageHeader.hpp header

Would you be so kind as to elaborate on it? Do we really need a const rvalue here?

The const snuck in there and shouldn't.

Also, the use of default is not going to make Visual Studio 2015 happy.

I'll see if I can get some time to explicitly define the correct move assignment operators in the generator today.

Take a look and let me know if this is handled for you appropriately now.

Hello @tmontgomery,

Thank you so much for the quick reply.
With the commit applied it works appropriately now.
