Building Ontology

The following document decribes how to build Ontology binaries from sources located at: https://github.com/ontio/ontology

Windows

  1. Install Visual Studio >= 2017 with CMake support.

2. Download and install Boost prebuilt binaries https://sourceforge.net/projects/boost/files/ boost-binaries/1.68.0/boost_1_68_0-msvc-14.1-64.exe, also add BOOST_ROOT to the Environment Variables.

  1. Download and install OpenSSL prebuilt binaries https://slproweb.com/products/Win32OpenSSL.html (Win64 OpenSSL v1.1.0h for example) and add OPENSSL_ROOT_DIR to the Environment Variables.
  2. Download and install QT 5.11 https://download.qt.io/official_releases/qt/5.11/5.11.0/qt-opensource-windows-x86-5.11.0.exe.mirrorlist and add QT5_ROOT_DIR to the Environment Variables (usually it looks like …/5.11.0/msvc2017_64), also add QML_IMPORT_PATH (it should look like %QT5_ROOT_DIR%qml). BTW disabling system antivirus on Windows makes QT installing process much faster.
  3. Add …/qt511/5.11.1/msvc2017_64/bin and …/boost_1_68_0/lib64-msvc-14.1 to the System Path.
  4. Open project folder in Visual Studio, select your target (Release-x64 for example, if you downloaded 64bit Boost and OpenSSL) and select CMake -> Build All.
  5. Go to CMake -> Cache -> Open Cache Folder -> beam (you’ll find beam.exe in the beam subfolder, beam-wallet.exe in ui subfolder).

Linux

  1. Create work directory and Get from source code
mkdir -p $GOPATH/src/github.com/ontio

cd $GOPATH/src/github.com/ontio

git clone https://github.com/ontio/ontology.git

or

go get github.com/ontio/ontology
  1. Fetch the dependent third party packages with glide.
$ cd $GOPATH/src/github.com/ontio/ontology
$ glide install
  1. Go to the project folder and call.
make all
  1. You’ll find two executable programs: “ontology” binary and “tools/sigsvr” in your project folder.

Mac

  1. Install Brew Package Manager.
  2. Install necessary packages using brew install openssl boost cmake qt5 command.
  3. Add export OPENSSL_ROOT_DIR=”/usr/local/opt/openssl” and export PATH=/usr/local/opt/qt/bin:$PATH to the Environment Variables.
  4. Go to Beam project folder and call cmake -DCMAKE_BUILD_TYPE=Release . && make -j4.
  5. You’ll find Beam binary in bin folder, beam-wallet in ui subfolder.

Note

If you don’t want to build UI don’t install QT5 and add -DBEAM_NO_QT_UI_WALLET=On command line parameter when you are calling cmake.
