Building Golos

Compile-Time Options (cmake)

CMAKE_BUILD_TYPE=[Release/Debug]

Specifies whether to build with or without optimization and without or with the symbol table for debugging. Unless you are specifically debugging or running tests, it is recommended to build as release.

LOW_MEMORY_NODE=[FALSE/TRUE]

Builds golosd to be a consensus-only low memory node. Data and fields not needed for consensus are not stored in the object database. This option is recommended for witnesses and seed-nodes.

CLEAR_VOTES=[TRUE/FALSE]

Clears old votes from memory that are no longer required for consensus.

BUILD_GOLOS_TESTNET=[FALSE/TRUE]

Builds golos for use in a private testnet. Also required for building unit tests.

Building under Docker

We ship a Dockerfile. This builds both common node type binaries.

git clone https://github.com/goloschain/golos
cd golos
docker build -t goloschain/golos .

Building on Ubuntu 16.04

For Ubuntu 16.04 users, after installing the right packages with apt Golos will build out of the box without further effort:

# Required packages
sudo apt-get install -y \
    autoconf \
    automake \
    cmake \
    g++ \
    git \
    libssl-dev \
    libtool \
    make \
    pkg-config

# Boost packages (also required)
sudo apt-get install -y \
    libboost-chrono-dev \
    libboost-context-dev \
    libboost-coroutine-dev \
    libboost-date-time-dev \
    libboost-filesystem-dev \
    libboost-iostreams-dev \
    libboost-locale-dev \
    libboost-program-options-dev \
    libboost-serialization-dev \
    libboost-signals-dev \
    libboost-system-dev \
    libboost-test-dev \
    libboost-thread-dev

# Optional packages (not required, but will make a nicer experience)
sudo apt-get install -y \
    doxygen \
    libncurses5-dev \
    libreadline-dev \
    perl

git clone https://github.com/goloschain/golos
cd golos
git submodule update --init --recursive
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make -j$(nproc) golosd
make -j$(nproc) cli_wallet
# optional
make install  # defaults to /usr/local

Building on Ubuntu 14.04

Here are the required packages:

# Required packages
sudo apt-get install -y \
    autoconf \
    cmake \
    g++ \
    git \
    libssl-dev \
    libtool \
    make \
    pkg-config

# Packages required to build Boost
sudo apt-get install -y \
    libbz2-dev \
    python-dev

# Optional packages (not required, but will make a nicer experience)
sudo apt-get install -y
    doxygen \
    libncurses5-dev \
    libreadline-dev \
    perl

Golos requires Boost 1.57 or later. The Boost provided in the Ubuntu 14.04 package manager (Boost 1.55) is too old. So building Golos on Ubuntu 14.04 requires downloading and installing a more recent version of Boost.

According to this mailing list post, Boost 1.58 is not compatible with gcc 4.8 (the default C++ compiler for Ubuntu 14.04) when compiling in C++11 mode (which Golos does). So we will use Boost 1.57; if you try to build with any other version, you will probably have a bad time.

Here is how to build and install Boost 1.57 into your user's home directory (make sure you install all the packages above first):

BOOST_ROOT=$HOME/opt/boost_1_57_0
URL='http://sourceforge.net/projects/boost/files/boost/1.57.0/boost_1_57_0.tar.bz2/download'
wget -c "$URL" -O boost_1_57_0.tar.bz2
[ $( sha256sum boost_1_57_0.tar.bz2 | cut -d ' ' -f 1 ) == \
    "910c8c022a33ccec7f088bd65d4f14b466588dda94ba2124e78b8c57db264967" ] \
    || ( echo 'Corrupt download' ; exit 1 )
tar xjf boost_1_57_0.tar.bz2
cd boost_1_57_0
./bootstrap.sh "--prefix=$BOOST_ROOT"
./b2 install

Then the instructions are the same as for golos:

git clone https://github.com/golosit/golos
cd golos
git submodule update --init --recursive
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make -j$(nproc) golosd
make -j$(nproc) cli_wallet

Building on macOS X

Install Xcode and its command line tools by following the instructions here: https://guide.macports.org/#installing.xcode. In OS X 10.11 (El Capitan) and newer, you will be prompted to install developer tools when running a developer command in the terminal.

Accept the Xcode license if you have not already:

sudo xcodebuild -license accept

Install Homebrew by following the instructions here: http://brew.sh/

Initialize Homebrew:

brew doctor brew update brew tap homebrew/versions

Install golos dependencies:

brew install \
    autoconf \
    automake \
    cmake \
    git \
    homebrew/versions/boost160 \
    libtool \
    openssl \
    python3

Note: brew recently updated to boost 1.61.0, which is not yet supported by golos. Until then, this will allow you to install boost 1.60.0.

Optional. To use TCMalloc in LevelDB:

brew install google-perftools

Clone the Repository

git clone https://github.com/golosit/golos.git
cd golos

Compile

export OPENSSL_ROOT_DIR=$(brew --prefix)/Cellar/openssl/1.0.2h_1/
export BOOST_ROOT=$(brew --prefix)/Cellar/boost160/1.60.0/
git submodule update --init --recursive
mkdir build && cd build
cmake -DBOOST_ROOT="$BOOST_ROOT" -DCMAKE_BUILD_TYPE=Release ..
make -j$(sysctl -n hw.logicalcpu)

Also, some useful build targets for make are:

golosd
chain_test
cli_wallet

e.g.:

make -j$(sysctl -n hw.logicalcpu) golosd

This will only build golosd.

Building on Other Platforms

  • Windows build instructions do not yet exist.

  • The developers normally compile with gcc and clang. These compilers should be well-supported.

  • Community members occasionally attempt to compile the code with mingw, Intel and Microsoft compilers. These compilers may work, but the developers do not use them. Pull requests fixing warnings / errors from these compilers are accepted.
