PX4 and ArduPilot are two separate softwares. If you want help building ArduPilot, this is the right place. If you want help building PX4, these are the right forums: http://discuss.px4.io/
what problems did you have? To set up the build environment in Ubuntu -
sudo apt-get -qq -y install git
git clone https://github.com/ArduPilot/ardupilot.git
cd ardupilot
git submodule update --init --recursive
./Tools/scripts/install-prereqs-ubuntu.sh -y
~/.profile
Then logout, log back in, and good to go
cd ardupilot
./waf configure --board sitl
./waf copter
For building the px4 firmware, I have tried the command make px4-v2. But I think the cloned ardupilot library have some problems in the files. When I run this command, it shows error in some .c programs. Also showing make[4] : Nothing to be done for ‘context’ error.
