h1. Jessie2

 (fork of the Jessie plugin for Frama-C)

*Jessie2* is a fork of the Jessie plug-in that allows deductive verification of C programs annotated with "ACSL":http://frama-c.com/acsl.html and is primarily targeted at Linux kernel modules source code. It uses the language and tools of the "Why3 verification platform":http://why3.lri.fr/. Unlike  original Jessie, Jessie2 is not distributed as a part of the "Why2 verification platform":http://why.lri.fr/ and is compiled/installed separately.

*Note*: For now, this fork requires modified version of the __Frama-C__ source code analysis platform, that is based on the @Neon 20140301@ version of the original platform.

h2. Installation

h3. Using OPAM

  * Install "OPAM":https://opam.ocaml.org/ as described on the OPAM "documentation":https://opam.ocaml.org/doc/Install.html.

    For example (installing to @/usr/local/bin@ unsing the binary installer):

    <pre><code class="bash">

    wget https://raw.github.com/ocaml/opam/master/shell/opam_installer.sh

    chmod +x opam_installer.sh

    sudo ./opam_installer.sh /usr/local/bin

    </code></pre>

  * Initialize OPAM to use the OCaml 4.02.1 compiler:

    <pre><code class="bash">

    opam init --comp 4.02.1

    eval `opam config env`

    </code></pre>

  * Install "Git":http://git-scm.com/.

    For example on Ubuntu:

    <pre><code class="bash">

    sudo apt-get install git

    </code></pre>

  * Add ISPRAS OPAM repository at @https://forge.ispras.ru/git/astraver.opam-repository.git@ with Jessie2 and modified Frama-C Neon packages to the OPAM installation

    (@ispras@ is just an arbitrary name of the new repository):

    <pre><code class="bash">

    opam repo add ispras https://forge.ispras.ru/git/astraver.opam-repository.git

    </code></pre>

  * Install external dependencies for the Jessie2 and Frama-C build i.e. Autoconf, Gtk2 development files and M4.

    Ubuntu example:

    <pre><code class="bash">

    sudo apt-get install $(opam install -e ubuntu jessie2)

    </code></pre>

  * Build and install the Jessie2 plugin for Frama-C with OPAM (the Frama-C itself will be built and installed automatically). One

    can use the @-j@ option to speed-up compilation on a multi-core machine:

    <pre><code class="bash">

    opam install -j 4 jessie2

    </code></pre>

  * Build and install either original or patched (negative assumption highlighting and minor explanation fixes) version of the Why3 verification platform:

    <pre><code class="bash">

    sudo apt-get install $(opam install -e ubuntu why3) # Install GMP (external dependency) on Ubuntu

    opam install -j 4 why3

    </code></pre>

  * The one using Jessie would also likely need SMT solvers e.g. "Alt-Ergo":http://alt-ergo.ocamlpro.com/ (also "Z3":http://http://z3.codeplex.com/, "CVC4":http://cvc4.cs.nyu.edu/web/ and others). Alt-Ergo can be installed via OPAM:

    <pre><code class="bash">

     opam install alt-ergo altgr-ergo satML-plugin

    </code></pre>

  * The Why3 IDE should be initialized to detect available provers (and plugins):

    <pre><code class="bash">

    why3 config --detect-provers --detect-plugins

    </code></pre>
