Compiling node-webkit on raspberry pi

how to

cd ~
mkdir .gyp
nano .gyp/include.gypi
paste the following
{
'variables': {
'linux_use_gold_binary' : 0,
'linux_use_gold_flags' : 0,
'target_arch': 'arm',
'disable_nacl': 1, # NaCL does not build for ARM.
'linux_use_tcmalloc': 0, # tcmalloc does not build for ARM.
'armv7': 0, # Optional, for targeting ARMv7.
'armv6': 1, # Optional, for targeting ARMv6.
'arm_thumb': 0, # Optional, for targeting thumb. Combine with armv7 to target thumb2.
'arm_neon': 0, # Optional, to disable NEON. 1 is the default, and most people want to keep it that way.
'arm_fpu': 'vfp', # Optional, to select which version of vfp to use if NEON is off. Default is vfpv3.
'verbose': 1,
'use_system_yasm': 0,
'werror' : ''
}
}

-Save

nano arm.env
paste the following
export CXX=g++
export CC=gcc
export AR=ar
export AS=as
export RANLIB=ranlib
export CFLAGS="-I/usr/include/gtk-2.0 -I/usr/include/glib-2.0 -march=armv6 -mfpu=vfp -mfloat-abi=hard"

export GYP_DEFINES="target_arch=arm disable_nacl=1 linux_use_tcmalloc=0 armv6=1 arm_thumb=0 use_libjpeg_turbo=0"
export GYP_GENERATORS='make'

-Save 

source arm.env

sudo nano /etc/dphys-swapfile
overwrite the file contients with
CONF_MAXSWAP=3072
CONF_SWAPSIZE=3072

-Save

sudo dphys-swapfile setup
sudo dphys-swapfile swapon


-Get the src for node-webkit (i wont document that here)

cd src/third_party/ffmpeg
nano ffmpeg.gyp and replace "armv7-a" with "armv6", "vfp16-d3" with "vfp" and remove mtune=cortex-a8 and mthumb options.

./configure --arch=armel --target-os=linux --enable-gpl
cp config.h chromium/config/Chromium/linux/arm/

cd ../../
nano third_party/node/deps/v8/SConstruct

now just run 
make nw -j4 BUILDTYPE=Release

the compile will take about 3 days so you better have a good magazine to read
