Install node java package on Raspberry Pi 2 B

NodeJavaOnPi.sh

# Because I'm not entirely sure if all the previous steps were needed or only the final one, I included other problems 
#   that may cause the node-gyp rebuild to fail during java installation (or bcrypt throwing install errors)
# This assumes you are using 7.8 "wheezy"

# More information regarding other distros: https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions

# Use the correct node version for the Raspberry ARM architecture:
# https://stackoverflow.com/questions/32563173/installing-node-js-on-raspberry-pi-2
wget http://yourARMarchitecurelink
cd /usr/local
sudo tar xzvf path/to/tarfile/yournodeversion.tar.gz --strip=1
#     If its .tar.xz   remove the -z flag from tar

# If you don't have `make` already
sudo apt-get update && sudo apt-get upgrade
sudo apt-get install build-essential

# Make sure you have gcc 4.8 and g++ 4.8, as its required for the latest node/node-gyp (4.0+ ?)
# https://stackoverflow.com/questions/33532528/nodejs-4-5-npm-install-fail-for-bcrypt-and-db-migrate
# I only had to do the 2 steps:
# If you had `make` and didnt already: sudo apt-get update && sudo apt-get upgrade
# NOTE THE BELOW MAY NOT BE THE BEST WAY, BUT IN THE END IT WORKED FOR ME
# I tried doing update-alternatives, but in the end I removed gcc and gcc 4.8 and started fresh
sudp apt-get remove gcc
sudo apt-get install gcc-4.8 g++-4.8
sudo ln -s /usr/bin/gcc-4.8 /usr/bin/gcc
sudo ln -s /usr/bin/g++-4.8 /usr/bin/g++
# Or instead of symlinking (if you know what youre doing)
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.8

# For me, jdk8 worked
sudo apt-get install oracle-java8-jdk

# Use python 2.7 when installing node-gyp/java package (also in node-gyp README):
# https://stackoverflow.com/questions/20454199/how-to-use-a-different-version-of-python-during-npm-install
npm config set python python2.7

# And finally thanks to:  https://github.com/joeferner/node-java/issues/179 & https://github.com/joeferner/node-java/pull/256
# The `gyp: Undefined variable javalibdir in binding.gyp while trying to load binding.gyp` was my main source
#   of anguish, which the below command fixed (which is a slight modification from the npm java README)
# DEPENDING ON MANY VARIABLES, TRY ANY ONE OF THE 4 METHODS MENTIONED IN URL. It took several trys to find the right combination:
GYP_DEFINES="armv7=0 javalibdir=/usr/lib/jvm/jdk-8-oracle-arm-vfp-hflt/jre/lib/arm/server/" CCFLAGS='-march=armv6' CXXFLAGS='-march=armv6' npm install java


# Hope this helps!
