Download the latest stable Doxygen release from the official website. Choose the appropriate installer for your operating system (Windows, macOS, Linux). Run the installer and follow the on-screen instructions. This usually involves selecting installation directory and components.
Configuring Your Doxygen Project
Create a Doxyfile. This configuration file controls Doxygen’s behavior. You can either create it manually or use Doxygen’s wizard. The wizard guides you through key settings; the manual approach offers more control. At a minimum, specify the project name, input files, and output directory. Adjust other parameters like the output format (HTML, LaTeX, etc.) and desired features (e. g., call graphs, inheritance diagrams) to suit your project’s needs. Experiment! The Doxygen documentation provides detailed descriptions for each setting.
For your input files, specify the paths to your source code files (`.c`, `.cpp`, `.h`, etc.) using the INPUT parameter. Add any necessary preprocessor definitions using the PREDEFINED parameter to ensure correct documentation generation for your code. Consider using a wildcard to include multiple files conveniently. For instance, INPUT = src/*.c src/*.h includes all `.c` and `.h` files in the `src` directory.
Once configured, run Doxygen from your command line or IDE. Point to your Doxyfile using the – f option (e. g., `doxygen – f Doxyfile`). Doxygen will then process your source code and generate documentation in your specified output directory. Explore the generated HTML documentation in a web browser.
