Don't attach images of text. You attached the error log (and I formatted it for you). Attach that short code **as text** in the post itself. — StoryTeller - Unslander Monica, Oct 16 '17 at 06:22
[Also, read this](https://stackoverflow.com/questions/12573816/what-is-an-undefined-reference-unresolved-external-symbol-error-and-how-do-i-fix). You should have googled and come across this post before posting your own. — StoryTeller - Unslander Monica, Oct 16 '17 at 06:25
