These are instructions for building stellar-core from source.
For a potentially quicker set up, the following projects could be good alternatives:
- stellar-core in a docker container
- stellar-core and horizon in a docker container
- pre-compiled packages
Best is to use the latest stable release that can be downloaded from https://github.com/stellar/stellar-core/releases
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
We maintain a pre-configured Docker configuration ready for development with VSCode.
See the dev container's README for more detail.

You can install the test toolchain to build and run stellar-core with the latest version of the llvm toolchain.
Alternatively, if you want to just depend on stock Ubuntu, you will have to build with clang and have use libc++
instead of libstdc++
when compiling.
Ubuntu 18.04 has clang-10 available, that you can install with
# install clang-10 toolchain
sudo apt-get install clang-10
After installing packages, head to building with clang and libc++.
# 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
# common packages
sudo apt-get install git build-essential pkg-config autoconf automake libtool bison flex libpq-dev libunwind-dev parallel
# if using clang
sudo apt-get install clang-10
# clang with libstdc++
sudo apt-get install gcc-8
# if using g++ or building with libstdc++
# sudo apt-get install gcc-8 g++-8 cpp-8
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 https://apt.llvm.org/
sudo apt-get install clang-format-10
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 parallel (required for running tests)
git clone https://github.com/stellar/stellar-core.git
cd stellar-core
git submodule init
git submodule update
- Type
./autogen.sh
. - Type
./configure
(If configure complains about compiler versions, tryCXX=clang-10 ./configure
orCXX=g++-8 ./configure
or similar, depending on your compiler.) - Type
make
ormake -j<N>
(where<N>
is the number of parallel builds, a number less than the number of CPU cores available, e.g.make -j3
) - Type
make check
to run tests. - Type
make install
to install.
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 18.04 LTS with clang-10:
# install libc++ headers
sudo apt-get install libc++-10-dev libc++abi-10-dev
Here are sample steps to achieve this:
export CC=clang-10
export CXX=clang++-10
export CFLAGS="-O3 -g1 -fno-omit-frame-pointer"
export CXXFLAGS="$CFLAGS -stdlib=libc++"
git clone https://github.com/stellar/stellar-core.git
cd stellar-core/
./autogen.sh && ./configure && make -j6
Configuring with --enable-tracy
will build and embed the client component of the Tracy high-resolution tracing system in the stellar-core
binary.
The tracing client will activate automatically when stellar-core is running, and will listen for connections from Tracy servers (a command-line capture utility, or a cross-platform GUI).
The Tracy server components can also be compiled by configuring with --enable-tracy-gui
or --enable-tracy-capture
.
The GUI depends on the capstone
, freetype
and glfw
libraries and their headers, and on linux or BSD the GTK-2.0
libraries and headers. On Windows and MacOS, native toolkits are used instead.
# On Ubuntu
$ sudo apt-get install libcapstone-dev libfreetype6-dev libglfw3-dev libgtk2.0-dev
# On MacOS
$ brew install capstone freetype2 glfw
