Compiling errors on Raspberry Pi 3

Hi.

I am trying to compile the latest version of Arducopter following the instruction as described in the documentation with “Building ArduPilot using Waf build system”. However, the build failed with a ‘mavlink’ error. ImportError: No module named future. Any help will be appreciated.

Thank you.

I have downloaded the latest stable binary from;
http://firmware.eu.ardupilot.org/Copter/stable/ and copied it into;
“opt/apm/bin/”. It is much simpler.
