Installing¶
Until BuildStream is available in your distro, you may need to install it yourself from source. The necessary steps are:
Install BuildStream (from a git checkout, or from PyPi)
Alternatively, BuildStream can be run in a container.
Installing Dependencies¶
Before installing BuildStream from source, it is necessary to first install the system dependencies. Below are some linux distribution specific instructions for installing these dependencies.
BuildStream requires the following base system requirements:
python3 >= 3.6
pip
BuildStream also depends on the host tools for the Source plugins.
Refer to the respective source plugin documentation for host tool
requirements of specific plugins.
The default plugins with extra host dependencies are:
bzr
git
patch
pip
tar
Arch Linux¶
Install the dependencies with:
sudo pacman -S python python-pip
For the default plugins:
sudo pacman -S bzr git lzip patch
Debian¶
Install the dependencies with:
sudo apt-get install \
python3 python3-pip python3-dev
For the default plugins:
- sudo apt-get install
lzip git bzr patch
Fedora¶
For recent fedora systems, the following line should get you the system requirements you need:
dnf install -y \
python3 python3-pip python3-devel
For the default plugins:
dnf install -y \
bzr git lzip patch
Installing BuildBox¶
BuildStream master now depends on buildbox-casd to manage the local CAS cache and communicate with CAS servers. buildbox-run is used for sandboxing. BuildBox components are still in development and there are no stable releases yet. Thus, they’re not available yet in Linux distros and they have to be manually installed.
These components can be installed from binaries, or built from source.
Install binaries¶
sha256sum 872f221d06752bb3b7815fa8e59929dcdbc275543728ad1485675eace1c3e8baThe tarball contains the binaries buildbox-casd, buildbox-fuse,
buildbox-run-bubblewrap and the symlink buildbox-run, which should be
extracted into a directory in PATH, e.g., ~/.local/bin.
Build from source¶
Each of the 4 buildbox components can be installed separately from their respective git repositiories, and each respository has individual install instructions. Make sure that you’re installing the correct version of each component.
Finally, configure buildbox-run-bubblewrap as the default buildbox-run implementation:
ln -sv buildbox-run-bubblewrap /usr/local/bin/buildbox-run
Installing BuildStream¶
Installing from PyPI¶
Once you have the base system dependencies, you can install the BuildStream python package as a regular user.
To install from PyPI, you will additionally require:
pip for python3 (only required for setup)
Python 3 development libraries and headers
For the latest dev snapshot of BuildStream 2, simply run the following command:
pip3 install --user --pre BuildStream
This will install latest dev snapshot of BuildStream and its pure python
dependencies into your user’s homedir in ~/.local.
Note
At time of writing, BuildStream 2 is only available as dev snapshots; this
is why the --pre option is required. Running
pip3 install --user BuildStream (without the --pre option)
will install Buildsteam 1.
You can also install a specific dev snapshot of Buildstream by specifying the
version. eg pip3 install --user BuildStream==1.93.2.dev0.
Available versions can be found on the BuildStream history page on PyPi.
Note that some of the oldest versions are not available on PyPI.
Keep following the instructions below to ensure that the bst
command is in your PATH.
Upgrading from PyPI¶
Once you have already installed BuildStream from PyPI, you can later update to the latest dev snapshot like so:
pip3 install --user --upgrade --pre BuildStream
Installing from a git checkout¶
To install directly from the git repository
using python’s pip package manager, you will additionally require:
pip for python3 (only required for setup)
Python 3 development libraries and headers
git (to checkout BuildStream)
Before installing, please check the existing tags in the git repository and determine which version you want to install.
Run the following commands:
git clone https://gitlab.com/BuildStream/buildstream.git
cd buildstream
git checkout <desired release tag>
pip3 install --user .
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.
Upgrading from a git checkout¶
If you installed BuildStream from a local git checkout using -e option, 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 in virtual environments¶
You can consider installing BuildStream in a Virtual Environment if you want to install multiple versions of BuildStream, or to isolate BuildStream and its dependencies from other Python packages.
Here is how to install BuildStream stable and development snapshot releases in virtual environments of their own:
# Install BuildStream stable in an environment called "venv-bst-stable"
# (At time of writing, this will be BuildStream 1)
python3 -m venv venv-bst-stable
venv-bst-stable/bin/pip install BuildStream
# Install BuildStream latest development snapshot in an environment
# called "venv-bst-latest"
# (At time of writing, this will be Buildstream 2)
python3 -m venv venv-bst-latest
venv-bst-latest/bin/pip install --pre BuildStream
To start using BuildStream from the desired environment, you will need to
activate it first. Activating it will automatically add bst to your PATH
and set up other necessary environment variables:
# Use BuildStream stable from venv-bst-stable
source venv-bst-stable/bin/activate
bst --version
# Use BuildStream latest from venv-bst-latest
source venv-bst-latest/bin/activate
bst --version
# Once you are done, remember to deactivate the virtual environment
deactivate
If you do not want to manage your virtual environments manually, you can consider using pipx.
Post-install setup¶
After having installed from source using any of the above methods, some setup will be required to use BuildStream.
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.
Buildstream Inside a Container¶
If your system cannot provide the base requirements, it is possible to run BuildStream within a container. This gives you an easy way to get started using BuildStream on any Unix-like platform where containers are available, including macOS.
