Homebrew Tap for Ethereum

Installation

brew tap ethereum/ethereum

Go client

brew install ethereum

C++ client

brew install cpp-ethereum
brew linkapps cpp-ethereum

Running

Go client

geth

C++ client

eth

Development

Get the latest development version with the --devel flag. Use --build-from-source if you don't want a pre-built bottle. Alternatively you can use the --successful flag (cpp-ethereum only, see important note below) or any other available options.

C++ client

brew reinstall cpp-ethereum --devel

For the latest successful build on develop (last successful build from cpt-obvious):

brew reinstall cpp-ethereum --devel --successful

Important note when using --successful

If you get an error looking like this:

==> Cloning https://github.com/ethereum/cpp-ethereum.git
Updating /Library/Caches/Homebrew/ethereum--git
fatal: reference is not a tree: <latest commit hash>
Error: Failed to download resource "ethereum"
Failure while executing: git checkout -q -f

Either try brew fetch cpp-ethereum --devel or simply delete the cache with rm -rf /Library/Caches/Homebrew/cpp-ethereum--git

Go client

brew reinstall ethereum --devel

Current branches

Go:

  • --devel is on develop branch
  • normal install is on master branch

C++:

  • --devel is on develop
  • normal install is on master branch

Upgrading

brew update && brew upgrade

Minor updates

Go client

brew update && brew reinstall ethereum

C++ client

brew update && brew reinstall cpp-ethereum

Versions

List available versions with:

ls -l /usr/local/Cellar/ethereum
ls -l /usr/local/Cellar/cpp-ethereum

If you have other versions installed, you can switch with:

brew switch ethereum <version>

Or follow this StackOverflow answer

These brews can be installed via the raw GitHub URLs, or by cloning this repository locally with brew tap ethereum/ethereum. You can also install binary bottles directly with brew install <bottle_url>, see cpt-obvious for previous builds.

Options

See brew info ethereum or brew info cpp-ethereum for all options. --with-... features are experimental patches.

cpp-ethereum options

Option desc.
--with-evmjit Build with LLVM and enable EVMJIT
--successful Last successful build using --devel only
--with-debug Pass -DCMAKE_BUILD_TYPE=Debug
--with-vmtrace Build with -DVMTRACE=1
--with-paranoia Build with -DPARANOID=1

Note: --with-evmjit requires LLVM to be installed with brew install llvm --HEAD --with-clang

Troubleshooting

  • Use --verbose to get more info while installing.
  • Make sure to update XCode and the command line tools.
  • Run brew update and brew upgrade
  • Fix what the brew doctor says.
  • Reinstall dependencies: brew reinstall boost --c++11 --with-python
  • Make changes to /usr/local/Library/Taps/ethereum/homebrew-ethereum/ethereum.rb
  • Reinstall with brew reinstall ethereum.rb (send a pull request!)
  • Take a walk

Patching

First cd /Library/Caches/Homebrew/ethereum--git/ and make your changes. Then git diff > shiny.patch, copy/paste the content of your patch under __END__ of ethereum.rb and replace the def patches block with:

def patches
  DATA
end

If you want to submit your change, save your patch in a gist, add your option 'shiny-option', 'Shiny description' and the URL to your gist in the patches block and submit a pull request. Make sure to send a pull request to Ethereum also!
