I am using C/C++ Eclipse. Is there an option in the IDE or an external tool to figure out the chain as to how a header file is eventually being included?

MSVS has an option that does just that. – Luchian Grigore Jan 21 '14 at 15:58

@LuchianGrigore I know MSVS has that option, but I'm using Eclipse – Iceman Jan 21 '14 at 15:59

@Iceman MSVC counts as an "external tool", doesn't it? – JBentley Jan 21 '14 at 16:06

You could just put an #error in the header file, the compiler should give you a trace like:
In file included from someheader.h:1:0,
from myheader.h:1,
from mysourcefile.c:1:
header_im_tracing.h:1:2: error: #error foobar

No it didn't show the complete chain.. only the header file and the parent source file. – Iceman Jan 21 '14 at 16:22

That depends on your compiler (not your IDE), on MinGW it does. Oh well :] – remram Jan 22 '14 at 18:56

An alternative would be to remove such header and try to build your project. Your compiler will (likely) show you the include chain.
