Introduction

This tutorial describes how to build the Go Ethereum Implementation from source on OSX Mavericks.

Since POC5, new PoC binaries are now released regularly on https://github.com/ethereum/go-ethereum/releases. This makes building from source a little less necessary than it used to, which is a good thing. That said, sometimes you might want to be building from source regardless, and the below guide should help you.

The below should work on any OSX Mavericks installation, and was successfully tested on a completely new install of OSX Mavericks.

For convenience, if you're worried about messing things up, you can always use a http://parallels.com virtual machine installed from your recovery partition - they offer a 14 day trial.

If you're finding yourself having difficulties, please post your question in the Go category: http://forum.ethereum.org/categories/go-implemenation.

Finally, for all documentation please refer to the wiki: https://github.com/ethereum/go-ethereum/wiki.


Installing

Keep in mind it is important that you do not use sudo. Sudoing is not required in most cases (after all, you installed most of your OSX apps without requiring it) and could lead to path issues down the line.

Install Brew

First, install brew. Installing brew will also install the xcode tools that are needed.

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

Now run brew doctor

brew doctor



Install Go and Dependencies

brew install gmp go

You no longer need to worry about setting up GOPATH etc... like you did in the previous tutorials.
You no longer need to install QT as Mist is now an Electron single page app, and is installed separately.



Install Go Ethereum

Find a nice folder to put go-ethereum in, then:
git clone https://github.com/ethereum/go-ethereum
cd go-ethereum
make geth


Run Go Ethereum!

You should now be able to use Geth, the go-ethereum CLI!

~/YOURFOLDER/go-ethereum/build/bin/geth console

CLI switches are documented here: https://github.com/ethereum/go-ethereum/wiki/Command-Line-Options


Troubleshooting

Note that the develop branch can sometimes have bugs, preventing it from building. If you hit such an issue let us know in the forums.

Your config files are in:
~/Library/Ethereum (contains the chain)
~/Library/Ethereum/keystore (contains your keys)
~/.ethash (contains the DAG when mining)


Upgrading

To upgrade to the latest release, simply go to the folder where you git cloned go-ethereum, and type
git pull
make geth

What's next?

To get started with Ethereum, the best place is our official gitbook at: http://ethereum.gitbooks.io/frontier-guide/content/

Once you have digested that, you can dig into the official solidity tutorial: https://github.com/ethereum/wiki/wiki/Solidity-Tutorial

If it's mining you'd like to learn more about, the guide is at https://forum.ethereum.org/discussion/197/mining-faq-live-updates
