Q:

Undefined symbols for architecture x86_64: CMMotionManager with SFML

I have been trying to build my SFML app for iOS but I keep running into hurdles. The latest of which is an error that I don't understand, I do not work on Mac much and therefore don't know what most of the errors mean. This specific error seems to be something to do with SFML itself. Is there anything I can do about that? Below is the error.
Undefined symbols for architecture x86_64:
"_OBJC_CLASS_$_CMMotionManager", referenced from:
   objc-class-ref in libsfml-window-s.a(SFAppDelegate.o)
ld: symbol(s) not found for architecture x86_64

I located CMMotionManager inside of SFML source, but I'm not sure how to fix this.
@property (nonatomic) CMMotionManager* motionManager;

Any help is much appreciated, please let me know if there is anything else you need to solve this problem, again, I don't know what most of the errors produced by XCode mean, so I don't know what to provide.
UPDATE:
Someone over on the SFML forums stated that it is possible I just forgot to link to the CoreMotion framework, I will try that as soon as I get back to my computer, and hopefully update this post again with the solution.

A:

The problem ended up being that I did not include the dependencies of libsfml-window-s.a in my project. One of the required dependencies was CoreMotion.framework.
