Problem to compile MD25_example

Hi, can somebody kindly help me with the following problem? When I compile MD25_example from Josh Villebrand I receive the following mesage:

MD25\MD25.cpp.o: In function MD25::sendWireCommand(unsigned char*, unsigned char)': C:\Arduino 1.5.5\libraries\MD25/MD25.cpp:217: undefined reference to I2c’
C:\Arduino 1.5.5\libraries\MD25/MD25.cpp:217: undefined reference to I2c' C:\Arduino 1.5.5\libraries\MD25/MD25.cpp:217: undefined reference to I2C::write(unsigned char, unsigned char, unsigned char*, unsigned char)’
MD25\MD25.cpp.o: In function MD25': C:\Arduino 1.5.5\libraries\MD25/MD25.cpp:31: undefined reference to I2c’

C:\Arduino 1.5.5\libraries\MD25/MD25.cpp:32: undefined reference to `I2C::timeOut(unsigned int)’

Library I2C is functional. Arduino 1.5.5
Tanks for any hint.

MD25 controller;

void setup() {
  controller = MD25(0xB0 >> 1);
  Wire.begin();

void loop()

Hi jugador!!

I've got the same problem, did you find any solution?

Thank you

You could try including the I2C header file in the sketch.
