Note for Raspbian and Armbian users: Compiling the bitcoin daemon will probably fail on a RPi or RPi clone due to insufficient memory. Fortunately, ARM binaries are available for both Bitcoin Core and Bitcoin ABC. See the binary installation page for details.

Install dependencies:

Make sure the required boost library development packages are installed:

    sudo apt-get install libboost-system-dev libboost-filesystem-dev libboost-program-options-dev libboost-chrono-dev libboost-test-dev libboost-thread-dev

You'll also need the following standard dependencies, if they're not already on your system:

    sudo apt-get install build-essential libtool autotools-dev autoconf pkg-config libssl-dev libdb-dev libdb++-dev libevent-dev

Compile and install Bitcoin Core:

Clone the Bitcoin Core repository from Github, configure, and build:

    $ git clone https://github.com/bitcoin/bitcoin.git
    $ cd bitcoin
    $ ./autogen.sh
    $ ./configure --without-gui --with-incompatible-bdb
    $ make -j4

The '-j4' option will speed the build process up by using 4 cores of a 4-core processor, if you have them. If overheating issues are a problem for your CPU or you're short on memory, you may want to omit it or use '-j2'.

For more detailed build information, consult the file doc/build-unix.md in the bitcoin source repository.

Your freshly compiled bitcoind daemon is now in the src/ directory. Install it, along with the 'bitcoin-cli' utility, into your executable path:

    $ cd src
    $ strip bitcoind bitcoin-cli
    $ sudo cp bitcoind /usr/local/bin
    $ sudo cp bitcoin-cli /usr/local/bin

Compile and install Bitcoin ABC (optional):

Regard Bitcoin ABC as experimental software. The author of the MMGen project has only partially reviewed its codebase and makes no guarantees regarding its safety or reliability.

If you want to transact BCH, also known as “Bitcoin Cash” or “Bcash”, then clone the Bitcoin ABC repository, and configure and build exactly as you did with Bitcoin Core above:

    $ git clone https://github.com/Bitcoin-ABC/bitcoin-abc
    $ cd bitcoin-abc
    $ ./autogen.sh
    $ ./configure --without-gui --with-incompatible-bdb
    $ make -j4

The resulting executable is also named 'bitcoind', so you must install it under a different name to avoid overwriting your Core daemon:

    $ cd src
    $ strip bitcoind bitcoin-cli
    $ sudo cp bitcoind /usr/local/bin/bitcoind-abc

From now on, you'll invoke the daemon as 'bitcoind-abc' instead of 'bitcoind'. Or alternatively, to simplify the starting and stopping of two daemons on the same machine, download and use the node start and stop scripts from the MMGenLive project:

    $ curl -O 'https://raw.githubusercontent.com/mmgen/MMGenLive/master/home.mmgen/bin/mmlive-node-{start,stop}'
    $ sudo install mmlive-node-{start,stop} /usr/local/bin

Refer to Run: on the binary installation page for instructions on running your freshly compiled bitcoin daemon(s).
