Installation

master brunch is always lastest release version of N2. Let’s start clone it. $> git clone https://github.com/kakao/n2.git Then, update sub modules git submodule update --init.

Python

The easiest way is to use pip. Simply do sudo pip install n2 to fetch the package from Python Package Index(PyPI). This will also install cython dependency.

For MacOS users, please set $CXX and $CC to your gcc/g++ path. e.g:

$> export CXX=/usr/local/bin/g++-7
$> export CC=/usr/local/bin/g++-7

If no gcc available, we recommend use brew to install gcc.

$> brew install gcc
$> export CXX=/usr/local/bin/g++-7  # check g++ location on your system
$> export CC=/usr/local/bin/g++-7
$> sudo pip install n2

You can also build from source by python setup.py install. You may want to run unit-test by issue the following command: make test_python.

C++

  1. make static_lib
    • if you need shared library, then type make shared_lib
  2. make install
    • you can specify where to install n2 with PREFIX environment value. default path is /usr/local/.
  3. make test_cpp # unit test

Go

  1. Set GOPATH first!
  2. make go

Requirements

  • gcc
  • openmp
  • spdlog
