Installing BuildStream
======================
BuildStream requires the following base system requirements:
* python3 >= 3.4
* libostree >= v2017.8 with introspection data
* bubblewrap >= 0.1.2
* fuse2
* PyGObject introspection bindings
* psutil python library (so you don't have to install GCC and python-devel to build it yourself)
BuildStream also depends on the host tools for the :mod:`Source <buildstream.source>` plugins.
Refer to the respective :ref:`authoring_source_plugins` documentation for host tool
requirements of specific plugins.
If you intend to push built artifacts to a remote artifact server,
which requires special permissions, you will also need:
* ssh
Installing from source (recommended)
------------------------------------
Until BuildStream is available in your distro, you will need to install
it yourself from the `git repository <https://gitlab.com/BuildStream/buildstream.git>`_
using python's ``pip`` package manager.
For the purpose of installing BuildStream while there are no distro packages,
you will additionally need:
* pip for python3 (only required for setup)
* Python 3 development libraries and headers
* git (to checkout buildstream)
Installing dependencies
~~~~~~~~~~~~~~~~~~~~~~~
Arch Linux
++++++++++
Install the dependencies with::
sudo pacman -S fuse2 ostree bubblewrap git \
python python-pip python-gobject python-psutil
Debian
++++++
Stretch
^^^^^^^
With stretch, you first need to ensure that you have the backports repository
setup as described `here <https://backports.debian.org/Instructions/>`_
By adding the following line to your sources.list::
deb http://ftp.debian.org/debian stretch-backports main
And then running::
sudo apt-get update
At this point you should be able to get the system requirements with::
sudo apt-get install \
fuse ostree gir1.2-ostree-1.0 bubblewrap git \
python3 python3-pip python3-gi python3-psutil
sudo apt-get install -t stretch-backports \
gir1.2-ostree-1.0 ostree
Buster or Sid
^^^^^^^^^^^^^
For debian unstable or testing, only the following line should be enough
to get the base system requirements installed::
sudo apt-get install \
fuse ostree gir1.2-ostree-1.0 bubblewrap git \
python3 python3-pip python3-gi python3-psutil
Fedora
++++++
For recent fedora systems, the following line should get you the system
requirements you need::
dnf install -y fuse ostree bubblewrap git \
python3 python3-pip python3-gobject python3-psutil
Installing
~~~~~~~~~~
Once you have the base system dependencies, you can clone the BuildStream
git repository and install it as a regular user::
git clone https://gitlab.com/BuildStream/buildstream.git
cd buildstream
pip3 install --user -e .
This will install buildstream's pure python dependencies into
your user's homedir in ``~/.local`` and will run BuildStream directly
from the git checkout directory.
Keep following the instructions below to ensure that the ``bst``
command is in your ``PATH`` and to enable bash completions for it.
.. note::
We recommend the ``-e`` option because you can upgrade your
installation by simply updating the checked out git repository.
If you want a full installation that is not linked to your
git checkout, just omit the ``-e`` option from the above commands.
Adjust PATH
~~~~~~~~~~~
Since BuildStream is now installed under your local user's install directories,
you need to ensure that ``PATH`` is adjusted.
A regular way to do this is to add the following line to the end of your ``~/.bashrc``::
export PATH="${PATH}:${HOME}/.local/bin"
.. note::
You will have to restart your terminal in order for these changes to take effect.
Bash completions
~~~~~~~~~~~~~~~~
Bash completions are supported by sourcing the ``buildstream/data/bst``
script found in the BuildStream repository. On many systems this script
can be installed into a completions directory but when installing BuildStream
without a package manager this is not an option.
To enable completions for an installation of BuildStream you
installed yourself from git, just append the script verbatim
to your ``~/.bash_completion``:
.. literalinclude:: ../../buildstream/data/bst
:language: yaml
Upgrading BuildStream
~~~~~~~~~~~~~~~~~~~~~
Assuming you have followed the default instructions above, all
you need to do to upgrade BuildStream is to update your local git
checkout::
cd /path/to/buildstream
git pull --rebase
If you did not specify the ``-e`` option at install time, you will
need to cleanly reinstall BuildStream::
pip3 uninstall buildstream
cd /path/to/buildstream
git pull --rebase
pip3 install --user .
Installing from distro packages
-------------------------------
Arch Linux
~~~~~~~~~~
Install `buildstream <https://aur.archlinux.org/packages/buildstream>`_
from `AUR <https://wiki.archlinux.org/index.php/Arch_User_Repository#Installing_packages>`_.
Alternatively, use
`buildstream-git <https://aur.archlinux.org/packages/buildstream-git>`_
for the lastest version of the development branch.
