Depending on your user privileges, you may have to precede some of the commands in the steps below with sudo.

Requirements

To get started with b9 using the Ninja build system, you'll need the following:

  • git
  • build-essential
  • nodejs (Minimum version 4.5.0)
  • npm
  • cmake (Minimum version 3.2.0)
  • ninja

You can install the packages above using the following command:

apt-get update && apt-get install git build-essential nodejs npm cmake

Clone the repository and get the submodules

git clone --recursive https://github.com/b9org/b9.git

Upgrade node.js

If you are running Ubuntu 16.04 and older, your nodejs may be older than version 4.5, in which case you will need to upgrade it. You can install newer nodejs binaries from NodeSource's PPA using:

curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash - \
&& sudo apt-get install -y nodejs

Check out this guide for more information on obtaining node.js packages.

You may run nodejs -v to verify that your nodejs version is 4.5.0 or above.

cd b9 \
&& npm install esprima

Build b9

mkdir build \
&& cd build \
&& cmake -GNinja -DCMAKE_BUILD_TYPE=Debug .. \
&& ninja
