Unresolved external error (LNK 2019)

[4Dimensional]

Is there any libraries that need to be included with this, because I am getting LNK2019 error messages. I'm using visual studio 2017.

You've not told me the link errors, but since I'm guessing you're on Windows you'll likely need an implementation of the POSIX getline() (this one works https://gist.github.com/MacDue/51c5f64e4d70fd3da8642f9599ad38d6)
