How can I make Doxygen generate full inheritance diagrams across multiple projects?

How can I configure Doxygen to generate comprehensive and detailed inheritance diagrams across multiple projects, ensuring clear documentation of code structure and relationships?

To generate comprehensive inheritance diagrams across multiple projects with Doxygen, you'll need to ensure that Doxygen is configured correctly and that it can access all relevant files. Here are some steps to help you achieve this:

Install Graphviz: Doxygen uses the dot tool from Graphviz to generate advanced diagrams. Make sure Graphviz is installed and available in your system's PATH.

Configure Doxygen: Edit your Doxygen configuration file (Doxyfile) to enable inheritance diagrams and set up Graphviz.

Include Multiple Projects: Ensure that your Doxygen configuration file includes paths to all relevant projects. You can use the INPUT setting to specify the directories containing your source files.

Make sure to include all directories that contain the relevant source files.

Run Doxygen: Once your configuration file is set up, run Doxygen to generate the documentation and inheritance diagrams

eview Output: Check the generated HTML or other output formats to ensure that the inheritance diagrams are complete and accurate. You may need to adjust the configuration settings if some classes or relationships are missing.

By following these steps, you should be able to generate detailed inheritance diagrams across multiple projects with Doxygen.
