Building: Ubuntu 12.0

The compiler that ships with Ubuntu 12.0 is too old to build libjsapi. Update it as follows:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update

To build on Debian 8.0 you should run the following script to install the required packages:

sudo apt-get install curl wget unzip bzip2 pkg-config zlib1g-dev
sudo apt-get install make autoconf automake libtool git ccache
sudo apt-get install gcc-4.9 g++-4.9
