Hi there,
i have some errors using I2Cdev.h and MPU6050_6Axis_MotionApps20.h at compiling/check in Arduino IDE
Arduino IDE version: 1.89
I have no idea what causes those errors... Can someone help please?
Thank you in advance...

Errors:

I had a similar problem. I resolved it my adding the i2cdev and mpu6050 library folders to the MY DOCUMENTS/ARDUINO/LIBRARIES FOLDER.

For some reason they need to be there even if they exist in the library folder of ARDUINO residing in the Program Files Folder.
