What is BuildStream?
`BuildStream <>`_ is a Free Software tool for
building/integrating software stacks.
It takes inspiration, lessons and use-cases from various projects including
OBS, Reproducible Builds, Yocto, Baserock, Buildroot, Aboriginal, GNOME Continuous,
JHBuild, Flatpak Builder and Android repo.
BuildStream supports multiple build-systems (e.g. autotools, cmake, cpan, distutils,
make, meson, qmake), and can create outputs in a range of formats (e.g. debian packages,
flatpak runtimes, sysroots, system images) for multiple platforms and chipsets.
Why should I use BuildStream?
BuildStream offers the following advantages:
* **Declarative build instructions/definitions**
BuildStream provides a flexible and extensible framework for the modelling
of software build pipelines in a declarative YAML format, which allows you to
manipulate filesystem data in a controlled, reproducible sandboxed environment.
* **Support for developer and integrator workflows**
BuildStream provides traceability and reproducibility for integrators handling
stacks of hundreds/thousands of components, as well as workspace features and
shortcuts to minimise cycle-time for developers.
* **Fast and predictable**
BuildStream can cache previous builds and track changes to source file content
and build/config commands. BuildStream only rebuilds the things that have changed.
* **Extensible**
You can extend BuildStream to support your favourite build-system.
* **Bootstrap toolchains and bootable systems**
BuildStream can create full systems and complete toolchains from scratch, for
a range of ISAs including x86_32, x86_64, ARMv7, ARMv8, MIPS.
How do I use BuildStream?
Please refer to the `documentation <>`_
for information about installing BuildStream, and about the BuildStream YAML format
and plugin options.
How does BuildStream work?
BuildStream operates on a set of YAML files (.bst files), as follows:
* Loads the YAML files which describe the target(s) and all dependencies.
* Evaluates the version information and build instructions to calculate a build
graph for the target(s) and all dependencies and unique cache-keys for each
* Retrieves previously built elements (artifacts) from a local/remote cache, or
builds the elements in a sandboxed environment using the instructions declared
in the .bst files.
* Transforms/configures and/or deploys the resulting target(s) based on the
instructions declared in the .bst files.
How can I get started?
To get started, first `install BuildStream by following the installation guide
and then follow our tutorial in the
`user guide <>`_.
