Hi everyone,
I am new in Ardupilot and I am trying to setting the environment on Windows following this guide
http://ardupilot.org/dev/docs/editing-the-code-with-eclipse.html#
I cloned the repository and downloaded the toolchain, and I managed to create a project from a template
on Eclipse Juno (the one provided downloading the toolchain).
The problem is that when I open an ArduCopter class (the one I am interested to) there are lots of compiling errors like the following on these screenshot.
I can’t understand what I am missing and I don’t know what to do anymore
I also tried to follow the guide for Linux, but in the end I get the same error
What should I do?
Where did I go wrong? I missed some inclusion or to download something?
Thanks everyone 
EDIT- after I posted this I saw that the images aren’t so clear, so the error are

ArduCopter/ArduCopter.cpp
ahrs.update();
Method ‘update’ could not be resolved.

ArduCopter/Copter.h
GCS_MAVLINK_Copter gcs_chan[MAVLINK_COMM_NUM_BUFFERS];
The type ‘GCS_MAVLINK_Copter’ must implement the inherited pure virtual method ‘GCS_MAVLINK::handleMessage’
