Hi,

I want to use cscope to extract all the dependencies between the
header files used in a large (10 MLOC) project. The project parses ok
and creates a correct database. However, I don't seem to have an
option in cscope to say "give me all the headers included directly,
or
indirectly, by a given file".


I need to do this BOTH for C (source) files as well as for headers
themselves, both project headers but also system headers (e.g.
stdio.h, etc)


Any ideas how to do this? If this is not directly possible in
cscope's
interface, I would be willing either to write some plugin that does
this, or maybe directly access the cscope.out database to query the
information.


Actually, I tried to do this with other tools and no luck (!!). Only
gcc/cpp seem to do this reliably, but they are very very slow on such
a large project...


Many thanks in advance for any hint on the this topic!!!


Alex
