Error when compiling Basic_SPI.ino / Arduino mega SDK

[Manujaya94]

I've got an error when compiling the Basic_SPI.ino to Arduino Mega ADK board.

More info would be useful. What is "Basic_SPI"? Is that your program sketch?
Have you included MPU9250.h at the top?
Are you using the Arduino IDE?

It appears you are using functions that don't exist in the library such as getAccelY_mss().
I have no clue what this is but sounds like you don't really know what you're doing. Unfortunately I can't help you much with that. Start from the example sketches and work your way from there. Issues here should mainly be about bugs/improvements etc :)

Actually i am sorry for the above error . That was actually my mistake.
