Undefined reference to _Unwind_Resume and __gxx_personality_v0

For those coming to this from google (like i did), the real cause of the undefined references to _Unwind_Resume and __gxx_personality_v0 is "using a gcc that uses a different stack unwinding method than dwarf2" [1]

In my case it was attempting to link code compiled with GCC 4.9 upwards with a library compiled with GCC 4.8 or below. The solution is to recompile the library with the same compiler you're building with.

I encountered that same problem attempting to use g++ -g -std=c++17 ... . I removed that option and, once I had removed use of a C++17 feature, it compiled, linked and ran.
