MPU6050 library multiple definitions error

[brakulla]

Hello,

I started to use MPU6050 library about a week ago and it was a delicious thing, thanks for that.

Since I want to use it in a quadcopter, sensor readings is not all the work, so I created a library and do the sensor stuff under that library for simplicity of the main program. That's when I encountered with multiple definitions problem.

In my library, I included 6 axis motion apps library and try to do initializing and reading. The error output is below. I use Visual Micro for Arduino programming but Arduino IDE gives the same error. I couldn't find multiple definitions, so any help would be great.

Thanks in advance.
