Can't Build ArduCopter on SkyViper v2450

Hello! I’m having trouble with building the firmware for Skyviper 2450

So, I simply followed the instructions in this site (, however I cant seem to build it.

I cloned the codes first using (Ubuntu)

git clone


cd ardupilot
git checkout skyviper-latest
git submodule update --init --recursive
./waf configure --board=px4-v3 (i also tried --board=skyviper-v2450, but it didnt work for the next step either)

However in this next step:

./waf build --target=bin/arducopter

I keep getting an error that said:

Build failed

Traceback (most recent call last):

File “/home/uavdlsu/ardupilot/modules/waf/waflib/”, line 270, in task_status

return tsk.runnable_status()

Any help would be appreciated. Thanks!

Exactly the same problem here.
