Hi, 
 Are you trying to include the MPU6050 driver that is present in the SDK? This driver does not have any functions with the name InitMPU6050 . Try with mpu6050_init(0x68) instead. 
 If you are trying to add another MPU6050 library, you need to include the path to the correct header files in your Makefile. 
 Best regards, 
 Jørgen
