You will need to install CUDA before installing kabukinai.

The most straight-forward way of doing this is to go to the NVIDIA CUDA website, and follow the instructions for your platform:

http://docs.nvidia.com/cuda/cuda-installation-guide-linux/

You will also need to install cmake before proceeding.

On Debian based linux systems, this can be done by executing at the command line:

# sudo apt-get install cmake

On RedHat based linux systems, execute (note that on CentOS you may first need to run yum install epel-release):

# sudo yum install cmake3

On OS X, cmake can be installed using Homebrew

# brew install cmake

First, get the source:

# git clone https://github.com/TESSscience/kabukinai.git

Build:

# make -C kabukinai

This places binaries in kabukinai/build/bin/.
