|
|
|
====================================
|
|
|
This guide will show you how to build bitcoind (headless client) for OSX.

|
|
Notes
|
|
|
-----
|
|
|
|
|
|
* Tested on OS X 10.7 through 10.10 on 64-bit Intel processors only.
|
|
|
|
|
|
* 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.
|
|
|
|
|
|
You will also need to install [Homebrew](http://brew.sh) in order to install library
|
|
|
dependencies.
|
|
|
|
|
|
The installation of the actual dependencies is covered in the Instructions
|
|
|
sections below.
|
|
|
|
|
|
Instructions: Homebrew
|
|
|
----------------------
|
|
|
|
|
|
#### Install dependencies using Homebrew
|
|
|
|
|
|
brew install autoconf automake libtool boost miniupnpc openssl pkg-config protobuf qt5
|
|
|
|
|
|
NOTE: Building with Qt4 is still supported, however, could result in a broken UI. As such, building with Qt5 is recommended.
|
|
|
|
|
|
#### 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/homebrew/homebrew/master/Library/Formula/berkeley-db4.rb -–without-java
|
|
|
```
|
|
|
|
|
|
The 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 link --force 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 --with-gui=qt5
|
|
|
make
|
|
|
|
|
|
3. It is also a good idea to build and run the unit tests:
|
|
|
|
|
|
make check
|
|
|
|
|
|
4. (Optional) You can also install bitcoind to your path:
|
|
|
|
|
|
make install
|
|
|
|
|
|
Use Qt Creator as IDE
|
|
|
------------------------
|
|
|
You can use Qt Creator as IDE, for debugging and for manipulating forms, etc.
|
|
|
Download Qt Creator from http://www.qt.io/download/. Download the "community edition" and only install Qt Creator (uncheck the rest during the installation process).
|
|
|
|
|
|
1. Make sure you installed everything through homebrew mentioned above
|
|
|
2. Do a proper ./configure --with-gui=qt5 --enable-debug
|
|
|
3. In Qt Creator do "New Project" -> Import Project -> Import Existing Project
|
|
|
4. Enter "bitcoin-qt" as project name, enter src/qt as location
|
|
|
5. Leave the file selection as it is
|
|
|
6. Confirm the "summary page"
|
|
|
7. In the "Projects" tab select "Manage Kits..."
|
|
|
8. Select the default "Desktop" kit and select "Clang (x86 64bit in /usr/bin)" as compiler
|
|
|
9. Select LLDB as debugger (you might need to set the path to your installtion)
|
|
|
10. Start debugging with Qt Creator
|
|
|
|
|
|
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-Core.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=10.7
|
|
|
-arch x86_64
|
|
|
-isysroot $(xcode-select --print-path)/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk
|
|
|
|
|
|
Once dependencies are compiled, see [doc/release-process.md](release-process.md) for how the Bitcoin-Core.app
|
|
|
bundle is packaged and signed to create the .dmg disk image that is distributed.
|
|
|
|
|
|
Running
|
|
|
-------
|
|
|
|
|
|
It's now available at `./bitcoind`, provided that you are still in the `src`
|
|
|
directory. We have to first create the RPC configuration file, though.
|
|
|
|
|
|
Run `./bitcoind` to get the filename where it should be put, or just try these
|
|
|
commands:
|
|
|
|
|
|
echo -e "rpcuser=bitcoinrpc\nrpcpassword=$(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
|
