Repo Workspace

All Scenarios OS uses repo to provide full workspace setup that includes all the repositories needed for building All Scenarios OS and developing on top.

The Repo Tool

In order to setup a sources workspace of All Scenarios OS, the git-repo tool is required on the host.

All Scenarios OS provides a patched version of the repo tool for Ubuntu 20.04 at launchpad PPA, for rpm/dnf based distributions at copr, and for openSUSE, Arch and a few other distributions at OBS.

The patches are also available in the tool’s source repository. One can install this tool by following the next steps:

On Ubuntu:

$ sudo add-apt-repository ppa:openharmony/tools
$ sudo apt-get update
$ sudo apt-get install git-repo

On distributions that use dnf:

$ sudo dnf copr enable openharmony/tools
$ sudo dnf --refresh install repo

On openSUSE or SUSE Enterprise Linux:

$ sudo zypper addrepo http://download.opensuse.org/repositories/home:/openharmony:/tools/openSUSE_Tumbleweed/home:openharmony:tools.repo
$ sudo zypper in repo

In the zypper addrepo line, replace openSUSE_Tumbleweed with the distribution you’re using - a list of distributions for which the package is available here.

On Arch Linux:

Add our OBS repository to /etc/pacman.conf:

[openharmony-tools]
Server = http://download.opensuse.org/repositories/home:/openharmony:/tools/Arch/$arch/

Optionally, install the repository’s signing key.

Then install the repo package with pacman.

On OpenMandriva:

OpenMandriva has already added All Scenarios OS’s version of repo to its official repositories. If you’re on OpenMandriva, simply dnf install repo.

The Manifests

The manifest repository provides the manifest for configuring a workspace. The project provides a single default.xml manifest file in each of the active branches.

Depending on the specific branch of the manifest repository, that manifest may either allow some projects to follow changes by selecting git branches or pin all projects to a specific git commit revision.

Setting up the Workspace

Once the repo tool is installed, you can initialize and populate the workspace. This will bring in all the needed sources for building All Scenarios OS:

$ mkdir ohos; cd ohos
$ repo init -u https://git.ostc-eu.org/OSTC/OHOS/manifest.git -b stable
$ repo sync --no-clone-bundle

You can checkout latest development source code by using develop branch instead of stable as part of the above repo init command.

Workspace structure

A fully set workspace, will provide a structure similar to:

./ohos/
└── sources
    ├── meta-freertos
    ├── meta-ohos
    ├── meta-openembedded
    ├── meta-zephyr
    ├── <various yocto layers>
    └── poky

The sources directory will include poky and all the build system layers that are part of the build process. Any new layers will be included under this directory.

It is recommended to use the root of the workspace for the build directories using build as directory name prefix.
