Answer 1

Judging from undefined reference to __gxx_personality_v0 linker message it looks like you are linking with gcc. You need to link C++ applications with g++. Or link with gcc and add -lstdc++ to the linker command line.

Answer 2

You aren't showing the relevant code and compiler invocation, but know that std::exception has an unimplemented virtual member function what() that you're expected to override, so don't go throwing naked std::exceptions if you want to callwhat().

Any of the derived, specific exceptions in <stdexcept> will implement what() and allow you to store a message when you're constructing the exception object.
