Install ros on drive agx

Hi shayNV,

All I do is just following the link:
http://wiki.ros.org/kinetic/Installation/Ubuntu . to install ros on the AGX Xavier A.
And I encountered the problem I mentioned.

Then I read the information on
ROS - How to cross compile ROS for DRIVE AGX Developer Kit with DRIVE Software 10.0
,

And I guess the meaning of“cross compile”is that compile ros of aarch64
architecture (which the AGX is) on the host pc (whose
architecture is x86_64)。Am I right about the understanding of the term “cross compile”?

And If I am right, could I just compile from the ros source code on the AGX Xavier A ? is and difference between them?
