Arduino DUE + i2C: massively problems with LCD LiquidCrystal LCD + Compass

Using Arduino Project Guidance
#1

It seems that the DUE has massively problems with the I2C library.

First I give it up to use a i2c compass (HMC 5883) and now also the LuqidCrystal LCD (SaintSmart) is not working.

#include <LiquidCrystal_I2C.h>

void setup(){}

void loop() {}

Error Message: libraries/LiquidCrystal_I2C/I2CIO.cpp:35: fatal error: …/Wire/Wire.h: No such file or directory. compilation terminated.

#include <Wire.h>

#include <LiquidCrystal_I2C.h>

void setup(){}

void loop() {}

Error Message: libraries/LiquidCrystal_I2C/LiquidCrystal.cpp: In member function ‘virtual void LiquidCrystal::setBacklight(uint8_t)’: libraries/LiquidCrystal_I2C/LiquidCrystal.cpp:173: error: expected primary-expression before ‘)’ token

// LCD Demo
#include <Wire.h>
#include <LCD.h>
#include <LiquidCrystal_I2C.h>
....

Error Message: LiquidCrystalSaintsmart16_2_Demo.ino: In function ‘void setup()’:
LiquidCrystalSaintsmart16_2_Demo:207: error: ‘PSTR’ was not declared in this scope
LiquidCrystalSaintsmart16_2_Demo:209: error: ‘fdevopen’ was not declared in this scope

Hint:All is working fine… if I use an UNO Board.

Has anybody got it to work with a DUE Board?
