gcc say is source fault . 

strndup is a macro in glibc header files.  Use (strndup) to disable the macro
function.

This is not a GCC bug or a glibc bug (since you supply  _GNU_SOURCE which says
define this macro) as the header is using something in the GNU_SOURCE
namespace.

I don't see what this has to do with building the X server - all the snippets
here are headers out of context.

When building the X server, the configure script detects if your platform has
strndup and defines HAVE_STRNDUP in dix-config.h & xorg-config.h, which xf86.h
includes when used inside the X server builds.

What are you really doing when you see this error?

I am trying compile VirtualBox-OSE-4.1.10 for Fedora 17, rpmfusion.org packages 

but I reduce the problem to 
teste.c 
#define _GNU_SOURCE 1
#include <xf86.h>

I also add 
#define HAVE_STRNDUP 1 to source and finally could compile the VirtualBox.   

./configure add defines, seems to me that is not the best way, but I don't know, I have to think and I'm not an expert. 
Thanks,

since all problem is not define HAVE_STRNDUP
are you saying ? that  
/usr/share/xorg-x11-server-source/include/xorg-config.h
and 
/usr/share/xorg-x11-server-source/include/dix-config.h
should define HAVE_STRNDUP ?
I want compile X11 parts of VirtualBox with Fedora X11 server sources.

I have no idea what you put in /usr/share/xorg-x11-server-source, but if you 
download the sources X.Org provides for the X server and run the configure 
script, it should put

#define HAVE_STRNDUP 1

in include/dix-config.h and include/xorg-server.h if your platform supports
strndup().

> I have no idea what you put in /usr/share/xorg-x11-server-source,

rpm -qf /usr/share/xorg-x11-server-source

xorg-x11-server-source-1.11.4-2.fc16.noarch

Neither do I, I use xorg-x11-server-source provide by Fedora 17

seems don't have it

fail without #define HAVE_STRNDUP 1

For Compile VirtualBox-4.3.8 for Fedora 21 . I still need define HAVE_STRNDUP

#define HAVE_STRNDUP 1

I manage to drop Buildrequires of xorg-x11-server-source-1.15.0-5.fc21 

Now we just need :
BuildRequires:  libdrm-devel
BuildRequires:  libpciaccess-devel
BuildRequires:  mesa-libGL-devel
BuildRequires:  mesa-libOSMesa-devel
BuildRequires:  pixman-devel
BuildRequires:  xorg-x11-proto-devel
BuildRequires:  xorg-x11-server-devel
BuildRequires:  libXcursor-devel
BuildRequires:  libXcomposite-devel
BuildRequires:  libXmu-devel

Please ask for more info and what information that you need ?

better look of fail without #define HAVE_STRNDUP 1

Hi , I think that find what I'm missing is include :

#include "/usr/share/xorg-x11-server-source/include/xorg-server.h"

to compile X11 drv for guest system (vm) of Fedora on VirtualBox

so this can bug report can be closed ?
