Subject [jira] [Commented] (IGNITE-2920) CPP: IgniteError should be derived from std::runtime_error not from std::exception

Igor Sapego commented on IGNITE-2920:
-------------------------------------

Vladimir,
The problem is that the signature of the {{std::exception::what()}} method has changed in
C++11. Thus we Ignite will not be able to be compiled for modern C++ if we leave it as it
is now.
As an alternative we can adjust signature of the {{IgniteError::what()}} with macros so it
will be valid for both C++11 and C++03.
What do you think?

> It seems like std::exception is not supposed to be used as a base class by user classes.
It is suggested to use std::runtime_error instead.
