description: Building Pantheon from source code

Build from Source

Prerequisites

!!!important Pantheon requires Java 8+ to compile; earlier versions are not supported.

Running Locally

Running On Virtual Machine

Installation on Linux / Unix / Mac OS X

###Clone the Pantheon Repository

Clone the PegaSysEng/pantheon repo to your home directory (/home/<user>):

$ git clone --recursive https://github.com/PegaSysEng/pantheon.git

Build Pantheon

After cloning, go to the pantheon directory.

Build Pantheon with the Gradle wrapper gradlew, omitting tests as follows:

$ ./gradlew build -x test

Go to the distribution directory:

$ cd build/distributions/

Expand the distribution archive:

$ tar -xzf pantheon-<version>.tar.gz

Move to the expanded folder and display the Pantheon help to confirm installation.

$ cd pantheon-<version>/
$ bin/pantheon --help

Continue with the Private Network Quickstart or Starting Pantheon.

Installation on Windows

!!!note Pantheon is currently supported only on 64-bit versions of Windows, and requires a 64-bit version of JDK/JRE. We recommend that you also remove any 32-bit JDK/JRE installations.

Install Pantheon

In Git bash, go to your working directory for repositories. Clone the PegaSysEng/pantheon repo into this directory:

git clone --recursive https://github.com/PegaSysEng/pantheon

Build Pantheon

Go to the pantheon directory:

cd pantheon

Open a Windows command prompt. Build Pantheon with the Gradle wrapper gradlew, omitting tests as follows:

.\gradlew build -x test

!!!note To run gradlew, you must have the JAVA_HOME system variable set to the Java installation directory. For example: JAVA_HOME = C:\Program Files\Java\jdk1.8.0_181.

Go to the distribution directory:

cd build\distributions

Expand the distribution archive:

tar -xzf pantheon-<version>.tar.gz

Move to the expanded folder and display the Pantheon help to confirm installation.

cd pantheon-<version>
bin\pantheon --help

Continue with the Private Network Quickstart or Starting Pantheon.

Installation on VM

You can run Pantheon on a virtual machine (VM) on a cloud service such as AWS or Azure, or locally using a VM manager such as VirtualBox.

If you set up your own VM locally using a VM manager such as VirtualBox, there are a few considerations:

  • Make sure that Intel Virtualization Technology (VTx) and Virtualization Technology for Directed I/O (VT-d) are enabled in BIOS settings.

  • On Windows, you might need to disable Hyper-V in the Windows Feature list.

It is recommended that you create a VM with the following attributes:

  • Memory Size: Set to 4096 (recommended)

  • Create a virtual hard disk with at least 10 GB; 20 GB is recommended

  • Virtual hard disk file type: VDI (if you need to share it with other apps, use VHD)

  • (Optional) You can create a shared directory in order to copy block files or genesis files from the host computer to the VM. For details on how to create a shared directory, see "Share Folders" in Install Ubuntu on Oracle VirtualBox.
