You need to install Homebrew, OS X command line tools, Git, and Go.

These instructions were tested on a fresh copy of OS X Mavericks, but they should work on most recent versions of OS X.

This document assumes that you are using the default shell, which is Bash.

Homebrew

Homebrew is a widely-used OS X package manager. We'll use it to install other prerequisites.

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

OS X command line tools

These are the standard UNIX command line tools for development.

Enterthe following command in a terminal window:

xcode-select --install

This will pop up a dialog window to install the command line tools:

Click “Install”.

Note, you can also install all of Xcode, but that's not needed for Vanadium unless you are using the Node.js libraries.

If you are using a version of OS X that is older than 10.9, you will need to get the command line tools for your version from https://developer.apple.com/downloads/ (login required).

Git

Vanadium code is managed using Git. Learn more about Git setup on GitHub.

The OS X command line tools include git, but usually an out-of-date copy. We recommend you install the latest version using Homebrew.

brew install git

Go

Go can be installed with an OS X package installer:

1. Download the darwin .pkg installer for your system and OS version from https://golang.org/dl/
2. Open it (double-click it in the Finder) and follow the instructions

The installer will install go in /usr/local and add /usr/local/go/bin to your PATH. You will have to open a new terminal window for the PATH change to take effect.

There are several alternative installation options described at golang.org.

You're all set
