I have received code of API at 05/13/2018 and it was build successfully, but when I have tried to build my project, I have received errors about undefined reference to method:
const client::JsonCppArray<Activity > get_items() const;
which declared in correspondent activities.h, but not defined in the activities.cpp.
Also I see in http_authorisation.cc not defined destructor for class AuthorizationCredentials, which was declared in http_authorization.h
