Considering the speed of the development of new features, or even Hardware is created in the OpenPOWER ecosystem, it's a challenge to get them in the traditional stable GNU/Linux distribution scenario.

open-power-host-os/builds repository is an open source collaboration effort that aims to help administrators to build and deploy the latest and greatest capabilities in the OpenPOWER world through a build script that provides software well packaged and designed for the Supported GNU/Linux distributions.

• CentOS 7.3 PPC64LE

Refer to 30. How does CentOS versioning work?.

• Clone the repository

git clone https://github.com/open-power-host-os/builds.git
cd builds

• Install epel repository (Extra Packages for Enterprise Linux):

sudo yum install epel-release

• Install RPM dependencies

sudo yum install -y $(cat rpm_requirements.txt)

• Add user to mock group

sudo usermod -a -G mock $(whoami)

• Build a single or multiple packages

./host_os.py build-packages --packages kernel libvirt

• Build all software

./host_os.py --verbose build-packages

Note the --verbose parameter to get all the log messages in the console. Instead of the standard ordinary messages. Please see --help for more options.

./host_os.py --help

or

./host_os.py build-packages --help

• Build old versions

For details on building OpenPOWER Host OS old versions, refer to the documentation at https://github.com/open-power-host-os/builds/blob/master/BUILD_OLD_VERSIONS.md.

• Build custom software

The build code keeps a cache of all packages source code (Git/Mercurial/SVN) repositories so that they do not need to be downloaded on every build. If it is desired to change the source code of a package, you may edit the package local repository content. To build the package from this modified local repository, either use a file:https:// URL pointing to it in the package metadata (YAML) file or disable package repositories update in config.yaml.

At the end of the process you'll see a new result directory inside this project's root. It contains the built packages repositories under packages and a yum repository config under repository_config, to simplify using those repositories.

To install them, follow the instructions here.
