OS X Build Instructions and Notes

This guide will show you how to build twisterd for OS X.

Notes

• Tested on OS X 10.9.1 on Intel processors only. PPC is not supported because it is big-endian.
• All of the commands should be executed in a Terminal application. The built-in one is located in /Applications/Utilities.

Preparation

You need to install Xcode with all the options checked so that the compiler and everything is available in /usr not just /Developer. Xcode should be available on your OS X installation media, but if not, you can get the current version from https://developer.apple.com/xcode/. If you install Xcode 4.3 or later, you'll need to install its command line tools. This can be done in Xcode > Preferences > Downloads > Components and generally must be re-done or updated every time Xcode is updated.

There's an assumption that you already have git installed, as well. If not, it's the path of least resistance to install GitHub Desktop or Git for OS X. It is also available via Homebrew or MacPorts.

You will also need to install Homebrew or MacPorts in order to install library dependencies. It's largely a religious decision which to choose, but I tested only with Homebrew.

The installation of the actual dependencies is covered in the Instructions sections below.

Instructions: HomeBrew

Install dependencies using Homebrew

brew install boost miniupnpc openssl berkeley-db4 autoconf automake libtool

Building twisterd

1. Clone the github tree to get the source code and go into the directory.

    git clone https://github.com/miguelfreitas/twister-core.git
    cd twister-core
   

2. Build twister using autotool

    ./autotool.sh
    ./configure --enable-logging --with-openssl=/usr/local/opt/openssl --with-libdb=/usr/local/opt/berkeley-db4
    make
   

(If you have multi core CPU, use "make -j N" where N = number of your cores)

3. If things go south, before trying again, make sure you clean it up:

    make clean
   

If all went well, you should now have a twisterd executable in the twister-core directory. See the Running instructions below.

Instructions: MacPorts (UNTESTED!!)

Install dependencies

Installing the dependencies using MacPorts is very straightforward.

sudo port install boost db48@+no_java openssl miniupnpc libtool

Once installed dependencies, do:

./autotool.sh
./configure --enable-logging
make

If things go south, before trying again, make sure you clean it up:

make clean

Running

It's now available at ./twisterd, provided that you are still in the twister-core directory. We have to first create the RPC configuration file, though.

Run ./twisterd to get the filename where it should be put, or just try these commands:

mkdir -p "/Users/${USER}/.twister"
echo -e "rpcuser=user\nrpcpassword=pwd\nrpcallowip=127.0.0.1" > "/Users/${USER}/.twister/twister.conf"
chmod 600 "/Users/${USER}/.twister/twister.conf"

When next you run it, it will start downloading the blockchain, but it won't output anything while it's doing this. This process may take several hours. If you see a lonely connect: Operation timed out, don't freak out, it seems to work fine.

Other commands:

tail -f ~/.twister/debug.log
./twisterd --help  # for a list of command-line options.
./twisterd -daemon # to start it as a daemon.
./twisterd help    # When the daemon is running, to get a list of RPC commands

In order to get the HTML interface, you'll have to download it and link it in .twister:

 git clone https://github.com/miguelfreitas/twister-html.git /Users/${USER}/Library/Application\ Support/twister/html

Once you do that, it will be available at http://localhost:28332/home.html

Troubleshooting

1. You get "DHT network down" in WEB interface on /network.html page

• Reboot your Mac
