Compile errors compiling MPU6050_example_1 for BCM2385

[Xantrim]

I tried to get an MPU 6050 working on a Raspberry PI. Compiling and installing the BCM2035 library was no problem, but when I try to compile the example I get the output at the bottom of this message. The trouble seems to be that it uses MPU6050.cpp from the Arduino part of the library, which uses functions not available outside the Arduino framework.

`gcc -o MPU6050_example_1 ${PATH_I2CDEVLIB}RaspberryPi_bcm2835/MPU6050/examples/MPU6050_example_1.cpp -I ${PATH_I2CDEVLIB}RaspberryPi_bcm2835/I2Cdev ${PATH_I2CDEVLIB}RaspberryPi_bcm2835/I2Cdev/I2Cdev.cpp -I ${PATH_I2CDEVLIB}/Arduino/MPU6050/ ${PATH_I2CDEVLIB}/Arduino/MPU6050/MPU6050.cpp -l bcm2835 -l m 1>error.log 2>&1
