c++ - Do you know tool building tree of include files in projectfile?

Question

Say, I'd like to have a tool (or script?) taking project (or .h file) and building searchable tree of "includes" included into it (of included into of included into and so so on). Is there exist something like this? Should I write this by myself [of course I am :), but may be somebody had it already written or may be has an idea how to get it]?

Answer 1

Not entirely sure this is what you're after, but you can easily get a list of includes by generating the post-CPP-processed file from the base c file, and grepping out the file/line number comments, e.g., using gcc

gcc -E main.c {usual flags} | grep '#' | cut -d' ' -f3 | sort | uniq

where main.c is your base c file.
