Out of memory, how to reduce this program's size

Something in these:
#include <Wire.h>
#include "I2Cdev.h"
#include "RTIMUSettings.h"
#include "RTIMU.h"
#include "RTFusionRTQF.h"
#include "CalLib.h"
#include <EEPROM.h>

Disable them 1 by 1, see who the culprit is.Might have to comment out code here & there as you go for the library calls as you it.
