## compiling-phantomjs-on-raspberry-pi.txt
There is an excellent article about compiling Phantomjs on Raspberry Pi 2:
http://raspberrypimaker.com/how-to-compile-phantomjs-on-the-raspberry-pi-2

But I would like to emphasize attention on one part which is RAM usage. RAM usage of cc1plus on this project is really huge. If you will
compile with `./build.py --jobs=N` where N is greater or equal 2 then you will propably run into issues:

If a process has been killed the first thing to do is to check `dmesg` and you can see that this was done by Linux OOM Killer:

[17714366.996789] Out of memory: Kill process 30580 (cc1plus) score 222 or sacrifice child

So I recommend compile only with single worker:

./build.py --jobs=1
