This is the Universa network codebase (Java core), containing the node, the console client (uniclient) and the associated subsystems.
To build, you need to have the following installed:
(Tested with Ubuntu 16.04 LTS).
First, install java-package (the tool that will help you to pack the Oracle JDK tarball into the .deb package). Also, install Gradle (the Java build tool using in Universa).
sudo apt-get install java-package gradle
Visit the Oracle JDK 8 site and download the tarball (.tar.gz) package for Linux x64. You will get a file like jdk-8u152-linux-x64.tar.gz (the title may vary, depending on the version).
Using the java-package framework, convert the tarball into the .deb package (replace the jdk-8u152-linux-x64.tar.gz with your specific name, if needed).
make-jpkg jdk-8u152-linux-x64.tar.gz
It will create a .deb package named accordingly. Install it (replace the oracle-java8-jdk_8u152_amd64.deb with your specific name, if needed).
sudo dpkg -i oracle-java8-jdk_8u152_amd64.deb
Now your Linux environment is ready to use Java and Gradle to build Universa.
Create a directory where the project will be placed, and run the following commands:
git clone git@github.com:UniversaBlockchain/universa.git ./
git submodule init; git submodule update
gradle build -x test
To successfully compile it, you may need GNU Multiple Precision Arithmetic Library (“libgmp”) installed. See the details specific to your operating system regarding how it can be installed.
