I am trying to use vector and boost property tree get() method but i am getting compile errors as follows. could you please help me in resolving these errors.

I am trying to get an std::vector<unsigned char> value using ptree (boost property tree) by typecasting as follows.
const std::vector<unsigned char> Result = pti.get<std::vector<unsigned char>>("XmlMsg.MsgDevice.MsgCommand.resultElement");

But I am getting the following errors: Please let me know how to resolve them.
