Where does this backward_warning.h #warning come from?

Without looking at every source file in my Xcode project, is there a way to find out which #include triggers the following warning?

#warning This file includes at least one deprecated or antiquated header. 
Please consider using one of the 32 headers found in section 17.4.1.2 of the 
C++ standard. Examples include substituting the <X> header for the <X.h> 
header for C++ includes, or <iostream> instead of the deprecated header 
<iostream.h>. To disable this warning use -Wno-deprecated.

Clicking on an error in Xcode simply opens the backward_warning.h file, which is completely useless.

I know what this warning means, I know how to fix it (when I see this file and can see it #includes) ... but I just don’t know how to find the file that causes the error

Use a parameter -Hfor GCC that will display the header files to be included (along with an indication of nesting so you can see which file includes the header).

-H , , backward_warning.h.

, hash_map, :

mikeb@ubuntu:~$ g++  -H -c test.cpp
. /usr/include/c++/4.4/backward/hash_map
.. /usr/include/c++/4.4/backward/backward_warning.h
In file included from /usr/include/c++/4.4/backward/hash_map:60,
                 from test.cpp:3:
/usr/include/c++/4.4/backward/backward_warning.h:28: warning: #warning This file
includes at least one deprecated or antiquated header which may be removed without
further notice at a future date. Please use a non-deprecated interface with equivalent 
functionality instead. For a listing of replacement headers and interfaces, consult 
the file backward_warning.h. To disable this warning use -Wno-deprecated.

... a bunch of snipped output ...

You have an old style header somewhere.

something like that

IE:

#include <iostream.h>  //instead of <iostream>
#include <stdlib.h>    //instead of <cstdlib>
#include <stdio.h>    //instead of <cstdio>

if it is included in the library, then I think you are SOL, I personally will not rummage through the library to make it work, you will have to use them to use namespaces. etc.
