Building OpenJDK Version 9 with OpenJ9

Our website describes a simple build process that uses Docker and Dockerfiles to create a build environment that contains everything you need to easily build a Linux binary of OpenJDK V9 with the Eclipse OpenJ9 virtual machine. A more complete set of build instructions are included here for multiple platforms:

Linux 🐧
AIX 📘
Windows 📒
MacOS 🍎
ARM 📱

Linux

🐧 This build process provides detailed instructions for building a Linux x86-64 binary of OpenJDK V9 with OpenJ9 on Ubuntu 16.04. The binary can be built directly on your system, in a virtual machine, or in a Docker container 🐳.

If you are using a different Linux distribution, you might have to review the list of libraries that are bundled with your distribution and/or modify the instructions to use equivalent commands to the Advanced Packaging Tool (APT). For example, for Centos, substitute the apt-get command with yum.

If you want to build a binary for Linux on a different architecture, such as Power Systems™ or z Systems™, the process is very similar and any additional information for those architectures are included as Notes 📝 as we go along.

1. Prepare your system

🐧 Instructions are provided for preparing your system with and without the use of Docker technology.

Skip to Setting up your build environment without Docker.

Setting up your build environment with Docker 🐳

If you want to build a binary by using a Docker container, follow these steps to prepare your system:

The first thing you need to do is install Docker. You can download the free Community edition from here, which also contains instructions for installing Docker on your system. You should also read the Getting started guide to familiarise yourself with the basic Docker concepts and terminology.
Obtain the Linux on 64-bit x86 systems Dockerfile to build and run a container that has all the correct software pre-requisites.

📝 Dockerfiles are also available for the following Linux architectures: Linux on 64-bit Power systems™ and Linux on 64-bit z Systems™

Either download one of these Dockerfiles to your local system or copy and paste one of the following commands:

For Linux on 64-bit x86 systems, run:

wget https://raw.githubusercontent.com/eclipse/openj9/master/buildenv/docker/jdk9/x86_64/ubuntu16/Dockerfile

For Linux on 64-bit Power systems, run:

wget https://raw.githubusercontent.com/eclipse/openj9/master/buildenv/docker/jdk9/ppc64le/ubuntu16/Dockerfile

For Linux on 64-bit z Systems, run:

wget https://raw.githubusercontent.com/eclipse/openj9/master/buildenv/docker/jdk9/s390x/ubuntu16/Dockerfile

Next, run the following command to build a Docker image, called openj9:

docker build -t openj9 Dockerfile .

Start a Docker container from the openj9 image with the following command, where -v maps any directory, <host_directory>, on your local system to the containers /root/hostdir directory so that you can store the binaries, once they are built:

docker run -v <host_directory>:/root/hostdir -it openj9

📝 Depending on your Docker system configuration, you might need to prefix the docker commands with sudo.

Now that you have the Docker image running, you are ready to move to the next step, Get the source.

Setting up your build environment without Docker

If you don't want to user Docker, you can still build an OpenJDK V9 with OpenJ9 directly on your Ubuntu system or in a Ubuntu virtual machine. Use the Linux on x86 Dockerfile like a recipe card to determine the software dependencies that must be installed on the system, plus a few configuration steps.

📝 Not on x86? We also have Dockerfiles for the following Linux architectures: Linux on Power systems and Linux on z Systems.

Install the list of dependencies that can be obtained with the apt-get command from the following section of the Dockerfile:

apt-get update \
  && apt-get install -qq -y --no-install-recommends \
    autoconf \
    ca-certificates \
    ...
    ...

📝 For Linux on z Systems, we specify the IBM SDK for Java 8 in the Dockerfile rather than the openjdk-8-jdk package because the IBM version contains a JIT compiler that will significantly accelerate compile time.

This build uses the same gcc and g++ compiler levels as OpenJDK, which might be backlevel compared with the versions you use on your system. Create links for the compilers with the following commands:

ln -s g++ /usr/bin/c++
ln -s g++-4.8 /usr/bin/g++
ln -s gcc /usr/bin/cc
ln -s gcc-4.8 /usr/bin/gcc

Download and setup freemarker.jar into a directory. The example commands use /root to be consistent with the Docker instructions. If you aren't using Docker, you probably want to store the freemarker.jar in your home directory.

cd /root
wget https://sourceforge.net/projects/freemarker/files/freemarker/2.3.8/freemarker-2.3.8.tar.gz/download -O freemarker.tgz
tar -xzf freemarker.tgz freemarker-2.3.8/lib/freemarker.jar --strip=2
rm -f freemarker.tgz

2. Get the source

🐧 First you need to clone the Extensions for OpenJDK for OpenJ9 project. This repository is a git mirror of OpenJDK without the HotSpot JVM, but with an openj9 branch that contains a few necessary patches. Run the following command:

git clone https://github.com/ibmruntimes/openj9-openjdk-jdk9

Cloning this repository can take a while because OpenJDK is a large project! When the process is complete, change directory into the cloned repository:

cd openj9-openjdk-jdk9

Now fetch additional sources from the Eclipse OpenJ9 project and its clone of Eclipse OMR:

bash ./get_source.sh

3. Configure

🐧 When you have all the source files that you need, run the configure script, which detects how to build in the current build environment.

bash ./configure --with-freemarker-jar=/root/freemarker.jar

⚠️ You must give an absolute path to freemarker.jar

4. Build

🐧 Now you're ready to build OpenJDK V9 with OpenJ9:

make all

⚠️ If you just type make, rather than make all your build will fail, because the default make target is exploded-image. If you want to specify make instead of make all, you must add --default-make-target=images when you run the configure script. For more information, read this issue.

Two Java builds are produced: a full developer kit (jdk) and a runtime environment (jre)

build/linux-x86_64-normal-server-release/images/jdk
build/linux-x86_64-normal-server-release/images/jre

🐳 If you built your binaries in a Docker container, copy the binaries to the containers /root/hostdir directory so that you can access them on your local system. You'll find them in the directory you set for <host_directory> when you started your Docker container. See Setting up your build environment with Docker.

📝 On other architectures the /jdk and /jre directories are in build/linux-ppc64le-normal-server-release/images (Linux on 64-bit Power systems) and build/linux-s390x-normal-server-release/images (Linux on 64-bit z Systems)

5. Test

🐧 For a simple test, try running the java -version command. Change to the /jre directory:

cd build/linux-x86_64-normal-server-release/images/jre

Run:

./bin/java -version

Here is some sample output:

openjdk version "9-internal"
OpenJDK Runtime Environment (build 9-internal+0-adhoc.openj9-openjdk-jdk9)
Eclipse OpenJ9 VM (build 2.9, JRE 9 Linux amd64-64 Compressed References 20171030_000000 (JIT enabled, AOT enabled)
OpenJ9   - 731f323
OMR      - 7c3d3d7
OpenJDK  - 1983043 based on jdk-9+181)

🐧 Congratulations! 🎉

AIX

📘

🚧 This section is still under construction. Further contributions expected.

The following instructions guide you through the process of building an OpenJDK V9 binary that contains Eclipse OpenJ9 on AIX 7.2.

1. Prepare your system

📘 You must install the following AIX Licensed Program Products (LPPs):

Java8_64
xlc/C++ 13.1.3
x11.adt.ext

A number of RPM packages are also required. The easiest method for installing these packages is to use yum, because yum takes care of any additional dependent packages for you.

Download the following file: yum_install_aix-ppc64.txt

This file contains a list of required RPM packages that you can install by specifying the following command:

yum shell yum_install_aix-ppc64.txt

It is important to take the list of package dependencies from this file because it is kept right up to date by our developers.

Download and setup freemarker.jar into your home directory by running the following commands:

cd /<my_home_dir>
wget https://sourceforge.net/projects/freemarker/files/freemarker/2.3.8/freemarker-2.3.8.tar.gz/download -O freemarker.tgz \
tar -xzf freemarker.tgz freemarker-2.3.8/lib/freemarker.jar --strip=2 \
rm -f freemarker.tgz

2. Get the source

📘 First you need to clone the Extensions for OpenJDK for OpenJ9 project. This repository is a git mirror of OpenJDK without the HotSpot JVM, but with an openj9 branch that contains a few necessary patches. Run the following command:

git clone https://github.com/ibmruntimes/openj9-openjdk-jdk9

Cloning this repository can take a while because OpenJDK is a large project! When the process is complete, change directory into the cloned repository:

cd openj9-openjdk-jdk9

Now fetch additional sources from the Eclipse OpenJ9 project and its clone of Eclipse OMR:

bash ./get_source.sh

3. Configure

📘 When you have all the source files that you need, run the configure script, which detects how to build in the current build environment.

bash ./configure --with-freemarker-jar=/<my_home_dir>/freemarker.jar /
                 --with-cups-include=<cups_include_path> /
                 --disable-warnings-as-errors

where <my_home_dir> is the location where you stored freemarker.jar and <cups_include_path> is the absolute path to CUPS. For example /opt/freeware/include.

4. build

📘 Now you're ready to build OpenJDK with OpenJ9:

make all

⚠️ If you just type make, rather than make all your build will fail, because the default make target is exploded-image. If you want to specify make instead of make all, you must add --default-make-target=images when you run the configure script. For more information, read this issue.

Two Java builds are produced: a full developer kit (jdk) and a runtime environment (jre)

build/aix-ppc64-normal-server-release/images/jdk
build/aix-ppc64-normal-server-release/images/jre

📝 A JRE binary is not currently generated due to an OpenJDK bug.

5. Test

📘 For a simple test, try running the java -version command. Change to the /jdk directory:

cd build/aix-ppc64-normal-server-release/images/jdk

Run:

./bin/java -version

Here is some sample output:

openjdk 9-internal
OpenJDK Runtime Environment (build 9-internal+0-adhoc..openj9-openjdk-jdk9)
Eclipse OpenJ9 VM (build 2.9, JRE 9 AIX ppc64-64 Compressed References 20171017_000000 (JIT enabled, AOT enabled)
OpenJ9   - d2e7c02
OMR      - 3271be8
OpenJDK  - 437530c based on jdk-9+181)

📘 Congratulations! 🎉

Windows

📒

The following instructions guide you through the process of building a Windows OpenJDK V9 binary that contains Eclipse OpenJ9. This process can be used to build binaries for Windows 7, 8, and 10.

1. Prepare your system

📒 You must install a number of software dependencies to create a suitable build environment on your system:

Cygwin, which provides a Unix-style command line interface. Install all packages in the Devel category. In the Archive category, install the packages zip and unzip. Install any further package dependencies that are identified by the installer. More information about using Cygwin can be found here.
Windows JDK 8, which is used as the boot JDK.
Microsoft Visual Studio 2013, which is the same compiler level used by OpenJDK. Later levels of this compiler are not supported.
Freemarker V2.3.8
Freetype2 V2.3

You can download Visual Studio, Freemarker, and Freetype manually or obtain them using the wget utility. If you choose to use wget, follow these steps:
Open a cygwin terminal and change to the /temp directory:

cd /cygdrive/c/temp

Run the following commands:

wget https://go.microsoft.com/fwlink/?LinkId=532495 -O vs2013.exe
wget https://sourceforge.net/projects/freemarker/files/freemarker/2.3.8/freemarker-2.3.8.tar.gz/download -O freemarker.tgz
wget http://download.savannah.gnu.org/releases/freetype/freetype-2.5.3.tar.gz

Before installing Visual Studio, change the permissions on the installation file by running chmod u+x vs2013.exe.
Install Visual Studio by running the file vs2013.exe.
To unpack the Freemarker and Freetype compressed files, run:

tar -xzf freemarker.tgz freemarker-2.3.8/lib/freemarker.jar --strip=2
tar --one-top-level=/cygdrive/c/temp/freetype --strip-components=1 -xzf freetype-2.5.3.tar.gz

2. Get the source

📒 First you need to clone the Extensions for OpenJDK for OpenJ9 project. This repository is a git mirror of OpenJDK without the HotSpot JVM, but with an openj9 branch that contains a few necessary patches.

Run the following command in the Cygwin terminal:

git clone https://github.com/ibmruntimes/openj9-openjdk-jdk9

Cloning this repository can take a while because OpenJDK is a large project! When the process is complete, change directory into the cloned repository:

cd openj9-openjdk-jdk9

Now fetch additional sources from the Eclipse OpenJ9 project and its clone of Eclipse OMR:

bash ./get_source.sh

3. Configure

📒 When you have all the source files that you need, run the configure script, which detects how to build in the current build environment.

bash configure --disable-warnings-as-errors --with-toolchain-version=2013 --with-freemarker-jar=/cygdrive/c/temp/freemarker.jar --with-freetype-src=/cygdrive/c/temp/freetype

📝 Modify the paths for freemarker and freetype if you manually downloaded and unpacked these dependencies into different directories. If Java 8 is not available on the path, add the --with-boot-jdk=<path_to_jdk8> configuration option.

4. build

📒 Now you're ready to build OpenJDK with OpenJ9:

make all

Two Java builds are produced: a full developer kit (jdk) and a runtime environment (jre)

build/windows-x86_64-normal-server-release/images/jdk
build/windows-x86_64-normal-server-release/images/jre

5. Test

📒 For a simple test, try running the java -version command. Change to the /jdk directory:

cd build/windows-x86_64-normal-server-release/images/jdk

Run:

./bin/java -version

Here is some sample output:

openjdk version "9-internal"
OpenJDK Runtime Environment (build 9-internal+0-adhoc.Administrator.openj9-openjdk-jdk9)
Eclipse OpenJ9 VM (build 2.9, JRE 9 Windows 8.1 amd64-64 Compressed References 20171031_000000 (JIT enabled, AOT enabled)
OpenJ9   - 68d6fdb
OMR      - 7c3d3d72
OpenJDK  - 198304337b based on jdk-9+181)
