I have no idea what might happen, I would like help to solve it.
Thanks in advance.
Its an issue with the latest Facebook SDK (Sept 10th 2015). Download the release before it.
See this answer https://stackoverflow.com/a/32519847/1052084 which worked for me.

The error indicates to you that Unrar4iOS is both defined in Unrar4iOS.a and as individual file in your project.
So go to:
TargetSettings->Build Phases->Link Binary with Libraries and remove the Unrar4iOS.
Seems you have added the same library twice thats why it says "duplicate symbol __Z12CallbackProcjlll "
The Unrar library is written in C++. If you don't have any .mm files in your project, then Xcode doesn't link against the C++ standard library, and all the references to C++ fail to link.
Here is a compiled test well framework: Unrar4iOS.framework
