Seeking tool to graphically show (header) file dependancies in C/C++

Question

I know that header guards avoid (most) trouble; call me @n@l if you like, but I just don't like a sloppy header-file tree.

If I draw on paper a box for each header file and connect them by lines representing #include, I like to see a neat hierarchy. But what I usually see is a complex web.

Maybe I am @n@l, but to me that tangled web represents sloppy-thinking and I would like to induce order by reorganizing the #include hierarchy.

Does anyone know of a tool which will let me vizualize the #include hierarchy? Preferably a free tool.

(and, yes, I know that I "could probably do it with graphviz dot", but that is not an answer ;-)

Answer 1

Doxygen can do this for you if you use it along with the dot tool.

Here is an example: http://www.neuraladvance.com/json-c/html/json_8h.html

Answer 2

You could try cinclude2dot
