Have you just #included the header (.h) file - but not added the source file (.c) to you project?

The pictures show where you call the functions - they do not show where you define them.

Where do you define them?

See: devzone.nordicsemi.com/.../156754

EDIT

Note that the Nordic SDKs require settings in the sdk_config.h file to enable (some of) the Nordic-provided definitions...

EDIT 2

See: https://devzone.nordicsemi.com/f/nordic-q-a/39503/undefined-reference-on-the-linker-level/152988#152988

Also search the forum for "undefined reference" and "L6218E" for many previous discussions ...
