Compiling Electroneum from Source

Dependencies

The following table summarizes the tools and libraries required to build. A few of the libraries are also included in this repository (marked as "Vendored"). By default, the build uses the library installed on the system, and ignores the vendored sources. However, if no library is found installed on the system, then the vendored source will be built and used. The vendored sources are also used for tatically-linked builds because distribution packages often include only shared library binaries (.so) but not static library archives (.a).

[1] On Debian/Ubuntu libgtest-dev only includes sources and headers. You must build the library binary manually. This can be done with the following command sudo apt-get install libgtest-dev && cd /usr/src/gtest && sudo cmake . && sudo make && sudo mv libg* /usr/lib/ [2] libnorm-dev is needed if your zmq library was built with libnorm, and not needed otherwise

Install all dependencies at once on Debian/Ubuntu:

sudo apt update && sudo apt install build-essential cmake pkg-config libboost-all-dev libssl-dev libzmq3-dev libsecp256k1-dev libunbound-dev libsodium-dev libunwind8-dev liblzma-dev libreadline6-dev libldns-dev libexpat1-dev doxygen graphviz libpgm-dev libusb-dev libgmp-dev

Install all dependencies at once on macOS with the provided Brewfile: brew update && brew bundle --file=contrib/brew/Brewfile

FreeBSD one liner for required to build dependencies pkg install git gmake cmake pkgconf boost-libs cppzmq libsodium libsecp256k1

Cloning the repository

Clone recursively to pull-in needed submodule(s):

$ git clone --recursive https://github.com/electroneum/electroneum

If you already have a repo cloned, initialize and update:

$ cd electroneum && git submodule init && git submodule update

On OSX: Homebrew installs OpenSSL but doesn’t link it to /usr/local/include, where the compiler looks into during #include<…> Thus, you must manually link it instead:

ln -s /usr/local/opt/openssl/include/openssl /usr/local/include ln -s /usr/local/Cellar/openssl/[version]/include/openssl /usr/bin/openssl ln -s /usr/local/opt/openssl/lib/libssl.1.0.0.dylib /usr/local/lib/

Build instructions

Electroneum uses the CMake build system and a top-level Makefile that invokes cmake commands as needed.

On Linux and macOS

• Install the dependencies

• Change to the root of the source code directory, change to the most recent release branch, and build:

  cd electroneum
  make

  Optional: If your machine has several cores and enough memory, enable parallel build by running make -j<number of threads> instead of make. For this to be worthwhile, the machine should have one core and about 2GB of RAM available per thread.

  Note: If cmake can not find zmq.hpp file on macOS, installing zmq.hpp from https://github.com/zeromq/cppzmq to /usr/local/include should fix that error.

  Note: The instructions above will compile the most stable release of the Monero software. If you would like to use and test the most recent software, use git checkout master. The master branch may contain updates that are both unstable and incompatible with release software, though testing is always encouraged.

• The resulting executables can be found in build/release/bin

• Add PATH="$PATH:$HOME/electroneum/build/release/bin" to .profile

• Run electroneum with electroneumd --detach

• Optional: build and run the test suite to verify the binaries:

  make release-test

  NOTE: core_tests test may take a few hours to complete.

• Optional: to build binaries suitable for debugging:

  make debug

• Optional: to build statically-linked binaries:

  make release-static

Dependencies need to be built with -fPIC. Static libraries usually aren't, so you may have to build them yourself with -fPIC. Refer to their documentation for how to build them.

• Optional: build documentation in doc/html (omit HAVE_DOT=YES if graphviz is not installed):

  HAVE_DOT=YES doxygen Doxyfile

On Windows:

Binaries for Windows are built on Windows using the MinGW toolchain within MSYS2 environment. The MSYS2 environment emulates a POSIX system. The toolchain runs within the environment and cross-compiles binaries that can run outside of the environment as a regular Windows application.

Preparing the build environment

• Download and install the MSYS2 installer, either the 64-bit or the 32-bit package, depending on your system.

• Open the MSYS shell via the MSYS2 Shell shortcut

• Update packages using pacman:

  pacman -Syu

• Exit the MSYS shell using Alt+F4

• Edit the properties for the MSYS2 Shell shortcut changing "msys2_shell.bat" to "msys2_shell.cmd -mingw64" for 64-bit builds or "msys2_shell.cmd -mingw32" for 32-bit builds

• Restart MSYS shell via modified shortcut and update packages again using pacman:

  pacman -Syu

• Install dependencies:

To build for 64-bit Windows:

  pacman -S git mingw-w64-x86_64-toolchain make mingw-w64-x86_64-cmake mingw-w64-x86_64-boost mingw-w64-x86_64-zeromq mingw-w64-x86_64-libsodium mingw-w64-x86_64-hidapi autoconf automake libtool
  git clone https://github.com/bitcoin-core/secp256k1 && cd secp256k1 && ./autogen.sh && ./configure && make && make install

To build for 32-bit Windows:

  pacman -S mingw-w64-i686-toolchain make mingw-w64-i686-cmake mingw-w64-i686-boost mingw-w64-i686-openssl mingw-w64-i686-zeromq mingw-w64-i686-libsodium mingw-w64-i686-hidapi autoconf automake libtool
  git clone https://github.com/bitcoin-core/secp256k1 && cd secp256k1 && ./autogen.sh && ./configure && make && sudo make install

• Open the MingW shell via MinGW-w64-Win64 Shell shortcut on 64-bit Windows or MinGW-w64-Win64 Shell shortcut on 32-bit Windows. Note that if you are running 64-bit Windows, you will have both 64-bit and 32-bit MinGW shells.

Cloning

• To git clone, run:

  git clone --recursive https://github.com/electroneum/electroneum.git

Building

• Change to the cloned directory, run:

  cd electroneum

• If you would like a specific version/tag, do a git checkout for that version. eg. 'v3.1.0.0'. If you don't care about the version and just want binaries from master, skip this step:

  git checkout v3.1.0.0

• If you are on a 64-bit system, run:

  make release-static-win64

• If you are on a 32-bit system, run:

  make release-static-win32

• The resulting executables can be found in build/release/bin

Building Portable Statically Linked Binaries

By default, in either dynamically or statically linked builds, binaries target the specific host processor on which the build happens and are not portable to other processors. Portable binaries can be built using the following targets:

• make release-static-linux-x86_64 builds binaries on Linux on x86_64 portable across POSIX systems on x86_64 processors
• make release-static-linux-i686 builds binaries on Linux on x86_64 or i686 portable across POSIX systems on i686 processors
• make release-static-linux-armv8 builds binaries on Linux portable across POSIX systems on armv8 processors
• make release-static-linux-armv7 builds binaries on Linux portable across POSIX systems on armv7 processors
• make release-static-linux-armv6 builds binaries on Linux portable across POSIX systems on armv6 processors
• make release-static-win64 builds binaries on 64-bit Windows portable across 64-bit Windows systems
• make release-static-win32 builds binaries on 64-bit or 32-bit Windows portable across 32-bit Windows systems

Running electroneumd

The build places the binary in bin/ sub-directory within the build directory from which cmake was invoked (repository root by default). To run in foreground:

./bin/electroneumd

To list all available options, run ./bin/electroneumd --help. Options can be specified either on the command line or in a configuration file passed by the --config-file argument. To specify an option in the configuration file, add a line with the syntax argumentname=value, where argumentname is the name of the argument without the leading dashes, for example log-level=1.

To run in background:

./bin/electroneumd --log-file electroneumd.log --detach

To run as a systemd service, copy electroneumd.service to /etc/systemd/system/ and electroneumd.conf to /etc/. The example service assumes that the user electroneum exists and its home is the data directory specified in the example config.

If you're on Mac, you may need to add the --max-concurrency 1 option to electroneum-wallet-cli, and possibly electroneumd, if you get crashes refreshing.
