* Installing and compiling from a tarball
   :PROPERTIES:
   :CUSTOM_ID: tar
   :END:

The latest release of Spot is version {{{LASTRELEASE}}}:

- {{{LASTTARBALL}}} (see also the {{{LASTNEWS}}})

Past releases can be found [[https://www.lrde.epita.fr/dload/spot/][in the same directory]].  If you are
interested in /future/ releases, you can always peek at the [[https://gitlab.lre.epita.fr/spot/spot/-/jobs/artifacts/next/browse?job=make-dist][last
successful development build]].

** Requirements

Spot requires a C++17-compliant compiler.  =g++= 7.0 or later, as well
as =clang++= 5.0 or later should work.

Spot expects a complete installation of Python (version 3.5 or later).
Especially, Python's headers files should be installed (the package to
install has a name like =python-dev= or =libpython3-dev= in most
distributions).  If you don't have Python installed, and do NOT want
to install it, you should run =./configure= with the
=--disable-python= option.

** Installation

The installation follows the usual =./configure=, =make=, =make install= steps.

Please *do* install Spot somewhere: while skipping =make install= and
running the command-line tools directly from the build directory
should work, it will be slower than if you run =make install= and run
the installed binaries.

By default, =make install= will install everything under
=/usr/local/=, so unless you have write access to this directory you
will either have to run =sudo make install=, or choose another
installation prefix.

For instance to install Spot in =~/usr= (i.e., in your home
directory), use

#+BEGIN_SRC sh
./configure --prefix ~/usr
make
make install
#+END_SRC

Files =INSTALL= and =README= included in the tarball contains more
explanations about the various options you can use during this
process.  Also note that =README= has a section about troubleshooting
installations.

* Installing the Debian packages
   :PROPERTIES:
   :CUSTOM_ID: Debian
   :END:

We build Debian packages for amd64 and i386, for both releases and the
development versions.  Packages for releases are built for Debian
Bullseye (a.k.a. Debian stable) while packages for development are built
for Sid (a.k.a. Debian unstable).

Here is how to install the stable packages:

#+BEGIN_SRC sh
wget -q -O - https://www.lrde.epita.fr/repo/debian.gpg | apt-key add -
echo 'deb http://www.lrde.epita.fr/repo/debian/ stable/' >> /etc/apt/sources.list
apt-get update
apt-get install spot libspot-dev spot-doc python3-spot # Or a subset of those
#+END_SRC

Here is how to install the unstable packages:

#+BEGIN_SRC sh
wget -O /etc/apt/trusted.gpg.d/lrde.gpg https://www.lrde.epita.fr/repo/debian.gpg
echo 'deb http://www.lrde.epita.fr/repo/debian/ unstable/' >> /etc/apt/sources.list
apt-get update
apt-get install spot libspot-dev spot-doc python3-spot # Or a subset of those
#+END_SRC

Note that our Debian repository is signed since that is the new Debian
policy, and both of the above command blocks start with a download of
our [[https://www.lrde.epita.fr/repo/debian.gpg][GPG key]].  Its fingerprint is =209B 7362 CFD6 FECF B41D 717F 03D9
9E74 44F2 A84A=, if you want to verify it.

The package =spot= contains the [[file:tools.org][command-line tools]]. =libspot-dev=
contains the header files if you plan to use Spot in a C++17
program. =spot-doc= contains some html (including these pages) and pdf
documentation. Finally =python3-spot= contains some Python bindings
(this package also installs some ipython notebooks that you can use as
examples).  The packages containing the libraries (=libspot0=,
=libbddx0=, =libspotltsmin0=) are automatically installed as
dependencies of the previous packages.

* Installing the Fedora packages
   :PROPERTIES:
   :CUSTOM_ID: Fedora
   :END:

We build Fedora packages for amd64, for both releases and the
development versions.  Both builds are currently made for Fedora 28.

Our `stable` repository contains RPM for released versions of Spot, add it with:
#+BEGIN_SRC sh
sudo dnf config-manager --add-repo https://www.lrde.epita.fr/repo/fedora/lrde.repo
#+END_SRC

Our `unstable` repository contains RPM for the development versions of Spot,
you can opt to use that instead:

#+BEGIN_SRC sh
sudo dnf config-manager --add-repo https://www.lrde.epita.fr/repo/fedora/lrde.repo
sudo dnf config-manager --set-enabled lrde-unstable
sudo dnf config-manager --set-disabled lrde-stable
#+END_SRC

Once the repository is set up, you can simply install Spot with:
#+BEGIN_SRC sh
sudo dnf install spot python3-spot spot-devel spot-doc
#+END_SRC
or a subset of those packages.  The package =spot= contains the
command-line tools, =python3-spot= contains the Python bindings,
=spot-devel= contains the C++ header files, and =spot-doc= the
documentation that you can also find online.  Those packages depends
on =libspot= that contains the shared libraries.

* Installing as a Conda package

  Spot is available as a [[https://anaconda.org/conda-forge/spot][Conda-forge package]] for Linux and OS X.

  A typical installation would go as follow:

#+BEGIN_SRC sh
  conda create --name myenv python=3.8 # adjust as desired
  conda activate myenv
  conda install -c conda-forge spot
#+END_SRC

  Note that this package is built automatically by the conda-forge
  infrastructure, but this requires some manual trigger after each
  release.  Therefore there might be a delay between the moment a
  release of Spot is announced, and the availability of the Conda
  package.

* Installing and compiling from git
   :PROPERTIES:
   :CUSTOM_ID: git
   :END:

The =master= branch of the git repository contains the code for the
latest released version, possibly with a few yet-to-be-released
bug fixes.  The =next= branch is the main development branch, and contains
the (working) code that should be part of the next major release.

To clone the git repository, use

#+BEGIN_SRC sh
git clone https://gitlab.lre.epita.fr/spot/spot.git
#+END_SRC

This should put you on the =next= branch by default.  From there, read
the [[https://gitlab.lre.epita.fr/spot/spot/blob/next/HACKING][HACKING]] file that should be at the top of your cloned repository:
it lists all the tools you should install before attempting to compile
the source tree.
