I am developing multiple libraries as part of the same project. Everything now compiles OK except for the one error message "error: id returned 1 exit status" from file "collect2.exe".

I have bumped into this problem before and learned to try to compile the project in the Arduino IDE. When I do this, I get the following:

Arduino: 1.6.7 Hourly Build 2015/12/11 06:50 (Windows 10), Board: "Arduino Nano, ATmega328"

D:\Users\Bob.ObigOne\Documents\Arduino\Rover\Rover.ino:28:21: fatal error: BJMotor.h: No such file or directory

#include "BJMotor.h"

                     ^

compilation terminated.

I have attached a screen shot of the Solution Explorer and the output log.
