Building arducopter 3.1.2 - missing libraries/AP_Math/edc.h


I have troubles with building arducopter 3.1.2 (from github).

My steps:

git clone -b ArduCopter-3.1.2 git://
make configure (in ArduCopter sub-directory)
make (in ArduCopter sub-directory)

But then I got this error:

make: *** No rule to make target /Users/creagel/arducopter/ardupilot/libraries/AP_Math/edc.h', needed by/var/folders/mm/d6b1g0yd2jvd2g1xn552vy6r0000gn/T/’. Stop.

The directory AP_Math has not this file inside:

AP_Math.cpp examples matrix3.cpp polygon.h rotations.h vector3.cpp
AP_Math.h keywords.txt matrix3.h quaternion.cpp vector2.cpp vector3.h
AP_Math_AVR_Compat.h location.cpp polygon.cpp quaternion.h vector2.h vectorN.h

What I am doing wrong?

I don’t use the process you are using but, if you are in Windows, try this: … ual-micro/

It works also with the free Atmel Studio 6.2
