I can guess you’ve probably solved it by now, but if not you can download the updated installer for CTRE TalonSRXs at the CTRE Website and use “#include <ctre/Phoenix.h>”. And the object has been changed to TalonSRX from CANTalon, but if you want to use it with WPILib Robotdrive and other things, you need to use WPI_TalonSRX.
