See https://www.cl.cam.ac.uk/~pes20/cerberus/.

To build Cerberus, you need opam (>= 2.0.0, see here to install) and OCaml (>= 4.12.0).

First install the dependencies (including lem and menhir) using opam:

$ opam install --deps-only ./cerberus-lib.opam ./cerberus.opam

Then build the CLI using:

$ make

The CLI can then be used either from the source directory using:

$ dune exec cerberus -- ARG1 .. ARGN

or, after doing $ make install, using the cerberus executable.

To fully remove all object and Lem generated files:

$ make distclean

To remove the object files, but keep the Lem generated files (allowing for faster build when only working on .ml files):

$ make clean

$ cerberus --exec file1.c ... fileN.c

This will elaborate to Core, link, look for a main() function, and start executing the Core from there. To see a printout of the return value, and to get a machine-friendly collection of stdout and stderr, add the --batch argument.

$ cerberus --args="arg1","arg2" file.c

• The C abstract syntax (Cabs) and the Ail intermediate representation can be printed with --ast=cabs and --ast=ail.

• The Ail intermediate representation and the Core program can be pretty-printed with --pp=ail and --pp=core.

$ cerberus file1.c ... fileN.c

This will elaborate the C translation units to Core programs, and link them, before returning silently.

Include directories can be added with the usual -I, and macros can be forwarded to the preprocessor using -D (and unset with -U).

For more, see cerberus --help

Various C programs can be found in tests/.

Install the common dependencies and the following extra ones:

• angstrom (0.15.0)

$ opam install angstrom

Then run:

$ make cerberus-bmc

To run:

$ cerberus-bmc --help

Install the common dependencies and the following extra ones:

• lwt
• fpath (0.7.3)
• ezgzip (0.2.3)
• cohttp-lwt-unix (5.0.0)

$ opam install lwt fpath ezgzip cohttp-lwt-unix

Then:

$ make web

This installs all the available web instances as webcerb.* and the web server cerberus-webserver.

To build the UI, install node package manager npm (sudo apt install nodejs npm ) and:

$ make ui

Edit the generated config.json.

Run:

$ cerberus-server --help

Install the common dependencies and the APRON library (tested with v0.9.12).

$ opam install apron

Then:

$ make absint

You can also compile all the targets with:

$ make all

See https://github.com/rems-project/cerberus/blob/master/backend/cn/INSTALL.md

$ make -f Makefile_docker

creates a Docker image than can be used for example with:

$ docker run --volume `PWD`:/data/ cerberus:0.1 tests/tcc/00_assignment.c --pp=core

This image contains all the source code.

The main Cerberus developer is Kayvan Memarian. Victor Gomes made substantial contributions across the system. Kyndylan Nienhuis worked on the operational semantics for C11 concurrency. Stella Lau is the main developer of Cerberus BMC. The CN backend is by Christopher Pulte and Thomas Sewell. The CHERI memory model is by Vadim Zaliva. Cerberus originated with Justus Matthiesen's 2010-11 Part II project dissertation and his 2011-12 MPhil dissertation. James Lingard's 2013-14 MPhil dissertation developed a certifying translation validator for simple C programs for the Clang front-end, w.r.t. the Cerberus and Vellvm semantics.
