Hi Fellows,

I am following the instructions on http://ardupilot.org/dev/docs/sitl-native-on-windows.html#sitl-native-on-windows to set up the SITL on the Windows and I ran into the problems, firstly, 

git clone git://github.com/ArduPilot/ardupilot.git did not check out all the files needed. i.e. dsdl in the uavcan 
is empty, therefore I have to check it out separately, secondly, there are compile error: please refer to the message below:

v.xian@SOPENG-VINCENT ~/ardupilot/ArduCopter
$ make sitl -j4

What did I do wrong?

Thank you in advance with best regards
