Do you know tool building tree of include files in project\file?

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]?

If I remember correctly, doxygen can do this.

There exists a tool called include gardener, which can be found here: https://github.com/feddischson/include_gardener This gives you the include tree in dot or graphml (xml) format. But it does not consider other preprocessor statements like #if, #else, #endif.

Include Finder is a pretty useful tool. It has some bugs, and hasn't been updated in a while, but the author does provide the source, so you can modify it to your liking.

Eclipse CDT has the Include Browser under Window --> Show View --> Other... --> C/C++ --> Include Browser.

I know this is an old question, a slightly more useful output than the gcc/g++ -E output alone would also used the -H flag (instead or in addition to):

g++ -H {my -I and other flags} -E -o /dev/null file.cpp

here is a sample output, tree structure helps figure out who included what as a bonus it also lists at the bottom which files may benefit from an include guard

. generated/gen-cpp/File.h
.. /usr/include/thrift/TProcessor.h
... /usr/lib/gcc/x86_64-redhat-linux/4.4.6/../../../../include/c++/4.4.6/string
.... /usr/lib/gcc/x86_64-redhat-linux/4.4.6/../../../../include/c++/4.4.6/x86_64-redhat-linux/bits/c++config.h
..... /usr/include/bits/wordsize.h
..... /usr/lib/gcc/x86_64-redhat-linux/4.4.6/../../../../include/c++/4.4.6/x86_64-redhat-linux/bits/os_defines.h

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.
