Hi,

I am looking for a tool that will display the hierarchy of include
files for a C(++) source. For example for the following files

a.c:
#include "b.h"
#include "c.h"

b.h:
#include "d.h"

c.h:
#include "b.h"

the output would look similar to

a.c
  #include "b.h"
    #include "d.h"
  #include "c.h"
    #include "b.h"
      #include "d.h"

I guess this should be doable by analysing the result of the
preprocessor run during compilation, e.g. when compiling with
'gcc -save-temps'.

Does anybody know if such a tool exists, and if so, where I can find
it? I would like to run it in RedHat Linux 7.1, compiler is gcc-3.0.

Thanks

Ulrich

PS: Probably someone will reply along the lines of "But this is
already included with RH Linux!", and make me look stupid. But what
the heck ...

It would have to be gcc-specific (there's not enough info in the output from
some other compilers - Sun for instance lobotomized theirs 5-6 years ago).  I
did some related work in cproto (to keep track of levels of include-files to
selectively emit prototypes from a limited depth of includes).

(it might be useful to make that generate a hierarchy listing)

But generally if I want to know the include structure, I just edit the .i file
and select the "#" lines into a different buffer.

gcc -H

 `cpp -H a.c > /dev/null' does the trick for me.

Ah, I just knew it had to be there, but I never thought it would be
that easy.

Thanks a lot.
