# Go

## Option 1: Homebrew tap <a href="#option-1-homebrew-tap" id="option-1-homebrew-tap"></a>

Assumptions:

* Brew is installed. If not, run:

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

  and follow the prompts.

```
brew tap lattice/lattice
brew install lattice
```

Install the latest develop branch with `--devel`.

Add `--with-gui` to brew the `mist` browser.

Then run `mist` (GUI) or `geth` (CLI)

For options and patches, see: <https://github.com/lattice/homebrew-lattice>

## Option 2: Manual installation <a href="#option-2-manual-installation" id="option-2-manual-installation"></a>

Assumptions:

* Go 1.2+ is installed. If not refer to [this](https://github.com/ethereum/go-ethereum/wiki/Installing-Go) page.
* Brew is installed. If not, run `ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"` and follow the prompts

Install Qt 5.4.x:

`brew install qt5`

Now configure some path for go-qml to properly build:

```
export PKG_CONFIG_PATH=/usr/local/opt/qt5/lib/pkgconfig
export CGO_CPPFLAGS="-I/usr/local/opt/qt5/include/QtCore"
export LD_LIBRARY_PATH=/usr/local/opt/qt5/lib
```

Compile **Mist**

```
go get github.com/lattice/go-lattice/cmd/mist
```

This should start Mist and connect you to the Lattice network. However, if you want a traditional `*.app` file we'll need to use our [build tool](https://github.com/ethereum/go-build).

```
git clone git@github.com:lattice/go-build.git
cd go-build/osx && python build.py
```

This will save a `Mist.app` in the **osx** directory.
