External dependencies are needed to build the
project, which can be pulled in automatically with <a href=https://nixos.org/nix/>nix</a> using the provided <code>default.nix</code> and <code>shell.nix</code>
files.</p><p>The project is written in Coq, a theorem prover, which is extracted to OCaml so that it can then be
compiled and executed. The dependencies of this project are the following:</p><ul><li><a href=https://coq.inria.fr/>Coq</a>: theorem prover that is used to also program the HLS tool.</li><li><a href=https://ocaml.org/>OCaml</a>: the OCaml compiler to compile the extracted files.</li><li><a href=https://github.com/ocaml/dune>dune</a>: build tool for ocaml projects to gather all the ocaml files and compile them in the right
order.</li><li><a href=http://gallium.inria.fr/~fpottier/menhir/>menhir</a>: parser generator for ocaml.</li><li><a href=https://github.com/ocaml/ocamlfind>findlib</a> to find installed OCaml libraries.</li><li><a href=https://gcc.gnu.org/>GCC</a>: compiler to help build CompCert.</li></ul><p>These dependencies can be installed manually, or automatically through Nix.</p><h2 id=downloading-compcert>Downloading CompCert
<a class=anchor href=#downloading-compcert>#</a></h2><p>CompCert is added as a submodule in the <code>lib/CompCert</code> directory. It is needed to run the build
process below, as it is the one dependency that is not downloaded by nix, and has to be downloaded
together with the repository. To clone CompCert together with this project, you can run:</p><div class=highlight><pre class=chroma><code class=language-shell data-lang=shell>git clone --recursive https://github.com/ymherklotz/vericert
</code></pre></div><p>If the repository is already cloned, you can run the following command to make sure that CompCert is
also downloaded:</p><div class=highlight><pre class=chroma><code class=language-shell data-lang=shell>git submodule update --init
</code></pre></div><h2 id=setting-up-nix>Setting up Nix
<a class=anchor href=#setting-up-nix>#</a></h2><p>Nix is a package manager that can create an isolated environment so that the builds are
reproducible. Once nix is installed, it can be used in the following way.</p><p>To open a shell which includes all the necessary dependencies, one can use:</p><div class=highlight><pre class=chroma><code class=language-shell data-lang=shell>nix-shell
</code></pre></div><p>which will open a shell that has all the dependencies loaded.</p><h2 id=makefile-build>Makefile build
<a class=anchor href=#makefile-build>#</a></h2><p>If the dependencies were installed manually, or if one is in the <code>nix-shell</code>, the project can be built
by running:</p><div class=highlight><pre class=chroma><code class=language-shell data-lang=shell>make -j8
</code></pre></div><p>and installed locally, or under the <code>PREFIX</code> location using:</p><div class=highlight><pre class=chroma><code class=language-shell data-lang=shell>make install
</code></pre></div><p>Which will install the binary in <code>./bin/vericert</code> by default. However, this can be changed by changing
the <code>PREFIX</code> environment variable, in which case the binary will be installed in <code>$PREFIX/bin/vericert</code>.</p><h2 id=testing>Testing
<a class=anchor href=#testing>#</a></h2><p>To test out <code>vericert</code> you can try the following examples which are in the test folder using the
following:</p><div class=highlight><pre class=chroma><code class=language-shell data-lang=shell>./bin/vericert test/loop.c -o loop.v
./bin/vericert test/conditional.c -o conditional.v
./bin/vericert test/add.c -o add.v
</code></pre></div><p>Or by running the test suite using the following command:</p><div class=highlight><pre class=chroma><code class=language-shell data-lang=shell>make <span class=nb>test</span>
</code></pre></div></p></article><footer class=book-footer><div class="flex flex-wrap justify-between"></div></footer><div class=book-comments></div><label for=menu-control class="hidden book-menu-overlay"></label></div><aside class=book-toc><nav id=TableOfContents><ul><li><ul><li><a href=#downloading-compcert>Downloading CompCert</a></li><li><a href=#setting-up-nix>Setting up Nix</a></li><li><a href=#makefile-build>Makefile build</a></li><li><a href=#testing>Testing</a></li></ul></li></ul></nav></aside></main></body></html>
