Software Requirements

The following software are required to use the tool (newer versions are OK):

Erlang/OTP 25 or newer
The security checkers requires Erlang/OTP 25 or newer
C++ compiler (g++ 4.3.6 or a newer version) -- for the NIF graph, the Kyoto Cabinet, and the duplicated code detectors
There are other optional dependencies depending on the used features/interfaces of the tool. These dependencies are listed under the wiki page of the corresponding features.

Source Packages

The current release is available with three different representations, one is the Mnesia representation, one that uses a C++ graph representation (so called NIF graph) and the new Kyoto Cabinet representation. You can choose between them at startup.

This package contains the source code of the release. Compilation requires only Erlang/OTP and a C++ compiler if you want to use the the NIF graph, the Kyoto Cabinet, and the duplicated code detector. For installation instruction please check the corresponding wiki page.
