Question

I have a situation where I am using a library (collection of C++ header files only) that is 80MB in size in my project.

Now, I am only including 3 header files from that library in one of my source codes, but unfortunately each one of those header files include other header files and so on.

I would like to find a way to somehow traverse the header files starting from the 3 header files that I initially include to list all the header files that are being used.

I am trying to do so, so I can only include the necessary header files from that huge library in hope of reducing its size.

Answer 1

GCC has the -M flag (and similar) to generate lists of dependencies. I imagine other compilers have something similar.
