How Can I Track Header File Dependencies in My C Code?

Tracking #include Dependencies: Methods and Tools

In software development, accurate tracking of header file dependencies is crucial for maintaining code integrity and preventing compilation errors. Suppose you wish to identify all files that directly or indirectly include a particular header. What tools and approaches can you utilize to accomplish this?

One recommended approach is to leverage GCC/G :

The -M option in GCC/G generates a list of include dependencies for a specified header file. While it lacks additional features found in other tools, it offers the advantage of directly accessing the compiler's internal information. This ensures that dependencies are accurate and sourced from the correct locations.
