# Installation guide

Urbit can be installed on most Unix systems.  There is no Windows
port.  Windows is a wonderful OS, we just haven't gotten to it yet.
Use a VM.

## Install as a package

### OS X - Homebrew

    brew install --HEAD homebrew/head-only/urbit

### Ubuntu or Debian

Third-party packages are available, at:

    https://github.com/yebyen/urbit-deb

Urbit is only supported on Jessie onward (but outbound HTTPS
requests only work on Stretch; I wish we knew why; help us!)

## Hand-build from source

First, install all external dependencies.  Then, make.

### Dependencies

urbit depends on:

    gcc (or clang)
    gmp
    libsigsegv
    openssl
    automake
    autoconf
    ragel
    cmake
    re2c
    libtool
    libssl-dev (Linux only)
    ncurses (Linux only)

#### Ubuntu or Debian

    sudo apt-get install libgmp3-dev libsigsegv-dev openssl libssl-dev libncurses5-dev git make exuberant-ctags automake autoconf libtool g++ ragel cmake re2c

#### Fedora

    sudo dnf install gcc gcc-c++ git gmp-devel openssl-devel openssl ncurses-devel libsigsegv-devel ctags automake autoconf libtool ragel cmake re2c

#### AWS

    sudo yum --enablerepo epel install gcc gcc-c++ git gmp-devel openssl-devel ncurses-devel libsigsegv-devel ctags automake autoconf libtool cmake re2c

#### OS X - Homebrew

    brew install git gmp libsigsegv openssl libtool autoconf automake cmake

#### OS X - Macports

    sudo port install git gmp libsigsegv openssl autoconf automake cmake

Although `automake`/`autoconf`/`libtool` are generally installed by
default, some have reported needing to uninstall and reinstall those
three packages, at least with Homebrew. Your mileage may vary.

#### FreeBSD

    pkg install git gmake gmp libsigsegv openssl automake autoconf ragel cmake re2c libtool

### Download and make

Clone the repo:

    git clone git://github.com/urbit/urbit.git

`cd` to the directory you just created:

    cd urbit

Run `make`:

    make

(On FreeBSD, use `gmake` instead.)
