Installation Instructions

These are instructions for building stellar-core from source.

For a potentially quicker set up, the following projects could be good alternatives:

Picking a version to run

Best is to use the latest stable release that can be downloaded from

Alternatively, branches are organized in the following way:

branch name description quality bar
master development branch all unit tests passing
testnet version deployed to testnet acceptance tests passing
prod version currently deployed on the live network no recall class issue found in testnet and staging

For convenience, we also keep a record in the form of release tags of the versions that make it to production:

  • pre-releases are versions that get deployed to testnet
  • releases are versions that made it all the way in prod

Build Dependencies

  • c++ toolchain and headers that supports c++14
    • clang >= 5.0
    • g++ >= 6.0
  • pkg-config
  • bison and flex
  • libpq-dev unless you ./configure --disable-postgres in the build step below.
  • 64-bit system
  • clang-format-5.0 (for make format to work)
  • pandoc
  • perl


Ubuntu 14.04

You will have to install the test toolchain in order to both build and run stellar-core.

Ubuntu 16.04

Just like 14.04, you can install the test toolchain to build and run stellar-core.

Alternatively, if you want to just depend on stock 16.04, you will have to build with clang and have use libc++ instead of libstdc++ when compiling.

After installing packages, head to building with clang and libc++.

Adding the test toolchain

# NOTE: newer version of the compilers are not
#    provided by stock distributions
#    and are provided by the /test toolchain
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update

Installing packages

# common packages
sudo apt-get install git build-essential pkg-config autoconf automake libtool bison flex libpq-dev
# if using clang
sudo apt-get install clang-5.0
# clang with libstdc++
sudo apt-get install gcc-6
# if using g++ or building with libstdc++
# sudo apt-get install gcc-6 g++-6 cpp-6

# optional: pandoc (to compile man pages)
sudo apt-get install pandoc

In order to make changes, you'll need to install the proper version of clang-format.

In order to install the llvm (clang) toolchain, you may have to follow instructions on

sudo apt-get install clang-format-5.0


When building on OSX, here's some dependencies you'll need:

  • Install xcode
  • Install homebrew
  • brew install libsodium
  • brew install libtool
  • brew install automake
  • brew install pkg-config
  • brew install libpqxx (If ./configure later complains about libpq missing, try PKG_CONFIG_PATH='/usr/local/lib/pkgconfig')
  • brew install pandoc



Basic Installation

  • git clone
  • cd stellar-core
  • git submodule init
  • git submodule update
  • Type ./
  • Type ./configure (If configure complains about compiler versions, try CXX=clang-5.0 ./configure or CXX=g++-6 ./configure or similar, depending on your compiler.)
  • Type make or make -j (for aggressive parallel build)
  • Type make check to run tests.
  • Type make install to install.

Building with clang and libc++

On some systems, building with libc++, LLVM's version of the standard library can be done instead of libstdc++ (typically used on Linux).

NB: there are newer versions available of both clang and libc++, you will have to use the versions suited for your system.

You may need to install additional packages for this, for example, on Linux Ubuntu:

# install libc++ headers
sudo apt-get install libc++-dev libc++abi-dev

Here are sample steps to achieve this:

export CC=clang-5.0
export CXX=clang++-5.0
export CFLAGS="-O3 -g1 -fno-omit-frame-pointer"
export CXXFLAGS="$CFLAGS -stdlib=libc++ -isystem /usr/include/libcxxabi"
git clone
cd stellar-core/
./ && ./configure && make -j6
