Mac OS X Build Instructions and Notes ==================================== This guide will show you how to build bitcoind(headless client) for OSX. Notes ----- * Tested on OS X 10.6 through 10.9 on 64-bit Intel processors only. Older OSX releases or 32-bit processors are no longer supported. * 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 also an assumption that you already have `git` installed. If not, it's the path of least resistance to install [Github for Mac](https://mac.github.com/) (OS X 10.7+) or [Git for OS X](https://code.google.com/p/git-osx-installer/). It is also available via Homebrew or MacPorts. You will also need to install [Homebrew](http://brew.sh) or [MacPorts](https://www.macports.org/) in order to install library dependencies. It's largely a religious decision which to choose, however, Homebrew is now used for building release versions. The installation of the actual dependencies is covered in the Instructions sections below. Instructions: MacPorts ---------------------- ### Install dependencies sudo port install boost db48@+no_java openssl miniupnpc autoconf pkgconfig automake libtool Optional: install Qt4 sudo port install qt4-mac qrencode protobuf-cpp ### Building `bitcoind` 1. Clone the github tree to get the source code and go into the directory. git clone git@github.com:bitcoin/bitcoin.git bitcoin cd bitcoin 2. Build bitcoind (and Bitcoin-Qt, if configured): ./autogen.sh ./configure make 3. It is a good idea to build and run the unit tests, too: make check Instructions: Homebrew ---------------------- #### Install dependencies using Homebrew brew install autoconf automake libtool boost miniupnpc openssl pkg-config protobuf qt Note: After you have installed the dependencies, you should check that the Homebrew installed version of OpenSSL is the one available for compilation. You can check this by typing openssl version into Terminal. You should see OpenSSL 1.0.1h 5 Jun 2014. If not, you can ensure that the Homebrew OpenSSL is correctly linked by running brew link openssl --force Rerunning "openssl version" should now return the correct version. If it doesn't, make sure `/usr/local/bin` comes before `/usr/bin` in your PATH. #### Installing berkeley-db4 using Homebrew The homebrew package for berkeley-db4 has been broken for some time. It will install without Java though. Running this command takes you into brew's interactive mode, which allows you to configure, make, and install by hand: ``` $ brew install https://raw.github.com/mxcl/homebrew/master/Library/Formula/berkeley-db4.rb -–without-java ``` These rest of these commands are run inside brew interactive mode: ``` /private/tmp/berkeley-db4-UGpd0O/db-4.8.30 $ cd .. /private/tmp/berkeley-db4-UGpd0O $ db-4.8.30/dist/configure --prefix=/usr/local/Cellar/berkeley-db4/4.8.30 --mandir=/usr/local/Cellar/berkeley-db4/4.8.30/share/man --enable-cxx /private/tmp/berkeley-db4-UGpd0O $ make /private/tmp/berkeley-db4-UGpd0O $ make install /private/tmp/berkeley-db4-UGpd0O $ exit ``` After exiting, you'll get a warning that the install is keg-only, which means it wasn't symlinked to `/usr/local`. You don't need it to link it to build bitcoin, but if you want to, here's how: $ brew --force link berkeley-db4 ### Building `bitcoind` 1. Clone the github tree to get the source code and go into the directory. git clone https://github.com/bitcoin/bitcoin.git cd bitcoin 2. Build bitcoind: ./autogen.sh ./configure make 3. It is also a good idea to build and run the unit tests: make check Creating a release build ------------------------ You can ignore this section if you are building `bitcoind` for your own use. bitcoind/bitcoin-cli binaries are not included in the Bitcoin-Qt.app bundle. If you are building `bitcoind` or `Bitcoin-Qt` for others, your build machine should be set up as follows for maximum compatibility: All dependencies should be compiled with these flags: -mmacosx-version-min=10.6 -arch x86_64 -isysroot $(xcode-select --print-path)/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.6.sdk For MacPorts, that means editing your macports.conf and setting `macosx_deployment_target` and `build_arch`: macosx_deployment_target=10.6 build_arch=x86_64 ... and then uninstalling and re-installing, or simply rebuilding, all ports. As of December 2012, the `boost` port does not obey `macosx_deployment_target`. Download `https://gavinandresen-bitcoin.s3.amazonaws.com/boost_macports_fix.zip` for a fix. Once dependencies are compiled, see release-process.md for how the Bitcoin-Qt.app bundle is packaged and signed to create the .dmg disk image that is distributed. Running ------- It's now available at `./bitcoind`, provided that you are still in the `src` directory. We have to first create the RPC configuration file, though. Run `./bitcoind` to get the filename where it should be put, or just try these commands: echo -e "rpcuser=bitcoinrpc\nrpcpassword=$(xxd -l 16 -p /dev/urandom)" > "/Users/${USER}/Library/Application Support/Bitcoin/bitcoin.conf" chmod 600 "/Users/${USER}/Library/Application Support/Bitcoin/bitcoin.conf" The next time 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; you can monitor its process by looking at the debug.log file, like this: tail -f $HOME/Library/Application\ Support/Bitcoin/debug.log Other commands: ------- ./bitcoind -daemon # to start the bitcoin daemon. ./bitcoin-cli --help # for a list of command-line options. ./bitcoin-cli help # When the daemon is running, to get a list of RPC commands
