Dependency analyzer for C/C++ projects

Project Description

cppdep performs dependency analysis among components/packages/package groups of a large C/C++ project. This is a rewrite of dep_utils(adep/cdep/ldep), which is provided by John Lakos’ book “Large-Scale C++ Software Design”, Addison Wesley (1996).


  • Indirect extern declarations of global variables or functions instead of including the proper component header with the declarations.
  • Embedded dynamic dependencies, such as dynamic loading and configurable internal services.
  • Preprocessing or macro expansion is not performed. Dependency inclusion via preprocessor meta-programming is not handled.
  • Dependency exclusion with C style multi-line comments or macros is not respected.


  1. Python 2.7 or 3.4+
  2. NetworkX
  3. pydot
  4. pydotplus
  5. PyYAML
  6. PyKwalify 1.6.0+

The dependencies can be installed with pip.

$ sudo pip install -r requirements.txt


From the source:

$ ./ install

The latest stable release from PyPi:

$ pip install cppdep


Create a configuration file that describes the project for analysis. config_schema.yml is given for guidance.

In the root directory of the project with the configuration file, run the following command to generate dependency analysis reports and graphs.

$ cppdep -c /path/to/config/file

More documentation and example configurations can be found in project wiki.


  • John Lakos for inventing the analysis and providing dep_utils.
  • Zhichang Yu for rewriting dep_utils into Python.
