Mac OS X Build Instructions and Notes

This guide will show you how to build twisterd for OSX.

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 for Mac (OS X 10.7+) 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

Note: After you have installed the dependencies, you should check that the Brew-installed version of OpenSSL is the one available for compilation. You can check this by typing

    openssl version

into Terminal. You should see OpenSSL 1.0.1e 11 Feb 2013.

If that's not the case, you could brew link --force openssl but it's a bad idea. Instead, it's enough to make sure the right openssl binary is on your $PATH:

    export PATH=/usr/local/opt/openssl/bin:$PATH

Building twisterd

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

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

2. Set system variables to match your environment. THIS IS IMPORTANT!

    export OPENSSL_INCLUDE_PATH=/usr/local/opt/openssl/include
    export OPENSSL_LIB_PATH=/usr/local/opt/openssl/lib
    export BDB_INCLUDE_PATH=/usr/local/opt/berkeley-db4/include
    export BDB_LIB_PATH=/usr/local/opt/berkeley-db4/lib
    export BOOST_INCLUDE_PATH=/usr/local/opt/boost/include
    export BOOST_LIB_PATH=/usr/local/opt/boost/lib
    export BOOST_LIB_SUFFIX=-mt
    export LDFLAGS="-L$OPENSSL_LIB_PATH -L$BDB_LIB_PATH -L$BOOST_LIB_PATH"
    export CPPFLAGS="-I$OPENSSL_INCLUDE_PATH -I$BDB_INCLUDE_PATH -I$BOOST_INCLUDE_PATH"
   

3. Build libtorrent

    cd libtorrent
    ./bootstrap.sh
    ./configure --enable-logging --enable-debug --enable-dht
    make
    # note: install is optional, might conflict with existing libtorrent install
    make install  
   

4. Build twisterd. Note: it will emit a lot of warnings, but as long as you don't get actual error messages, it should be fine:

    cd ../
    cd src
    make -f makefile.osx
   

5. It is a good idea to build and run the unit tests, too:

   make -f makefile.osx test
   

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

    make -f makefile.osx clean

If all went well, you should now have a twisterd executable in the src 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

Building twisterd

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

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

2. Build twisterd:

   cd src
   make -f makefile.osx
   

3. It is a good idea to build and run the unit tests, too:

   make -f makefile.osx test
   

Running

It's now available at ./twisterd, provided that you are still in the src 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:

echo -e "rpcuser=user\nrpcpassword=pwd" > "/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:

./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 git@github.com:miguelfreitas/twister-html.git
ln -s twister-html /Users/${USER}/.twister/html
