Installation procedure on Linux
===============================
We cover first Debian-like distribution, then a generic recipie for all other
version is given.
Installation procedure on Debian/Ubuntu
---------------------------------------
PyFAI has been designed and originally developed on Ubuntu and debian-linux.
Now, the pyFAI library is included into debian, Ubuntu and
Mint distribution for example.
To install the package provided by the distribution, use:
.. code-block:: shell
sudo apt-get install pyfai
The issue with distribution based installation is the obsolescence of the version
available.
Thanks to the work of Frédéric-Emmanuel Picca, the debian package of pyFAI
provides a pretty good template which allows continuous builds.
From silx repository
++++++++++++++++++++
You can automatically install the latest nightly built of pyFAI with:
.. code-block:: shell
wget http://www.silx.org/pub/debian/silx.list
wget http://www.silx.org/pub/debian/silx.pref
sudo mv silx.list /etc/apt/sources.list.d/
sudo mv silx.pref /etc/apt/preferences.d/
sudo apt-get update
sudo apt-get install pyfai
**Nota:** The nightly built packages are not signed, hence you will be prompted
to install non-signed packages.
Build from sources
++++++++++++++++++
One can also built the current development version from sources:
.. code-block:: shell
sudo apt install git
sudo apt-get build-dep pyfai
git clone https://github.com/silx-kit/pyFAI
cd pyFAI
./build-deb.sh --install
The first line installes all the dependences for building
*debian* package, including debug and documentation.
The build procedure last for a few minutes and you will be prompted for your
password in order to install the freshly built packages.
The *deb-*files, available in the *package* directory are backports for your local
installation.
Installation procedure on other linux distibution
-------------------------------------------------
If your distribution does not provide you pyFAI packages, using the **PIP** way
is advised, via wheels packages. First install *pip* and *wheel* and activate a
virtual environment:
.. code-block:: shell
python3 -m venv pyfai
source pyfai/bin/activate
pip install pyFAI
Or you can install pyFAI from the sources:
.. code-block:: shell
python3 -m venv pyfai
source pyfai/bin/activate
pip install build
git clone https://github.com/silx-kit/pyFAI
cd pyFAI
pip install -r requirements.txt
pip install . --upgrade
**Nota:** One should never use *sudo pip* as it is likely to interfer with the software installed with the system.
