Ethos Checker

A Flexible and Efficient Proof Checker for SMT Solvers

Building the Ethos checker

You need CMake (>= version 3.12) and GMP to build the Ethos Checker.

To build a regular build, issue:

cd /path/to/ethos_checker
./configure.sh
    # use --prefix to specify an install prefix (default: /usr/local)
    # use --name=<PATH> for custom build directory
cd <build_dir>   # default is ./build
make             # use -jN for parallel build with N threads
make install     # to install into the prefix specified above

The executable, called ethos, will be created in the <build_dir>/src folder.

The ethos's build system provides the following pre-defined build profiles:

• release: Optimized, assertions and tracing disabled.

• debug: Unoptimized, debug symbols, assertions, and tracing enabled.

The default build profile is release, which you will get if you just run ./configure.sh. To choose a different build profile use:

./configure.sh <profile>

Using the Ethos checker

ethos [script]

where script is a Eunoia script. See tests and proofs for examples.

Running Tests

You can add tests in the tests directory.

Run them using make test in the build directory.

You can also filter tests using regular expressions for example:

ctest -R arith
