Xen users - Jun 2011 - Compiling Xen 4.1 on SL6: error: libslirp.h: No such file or directory

Hi,

I am trying to build Xen 4.1 (from the tarball) on Scientific Linux 6.0

I managed to get Xen itself built through ''make xen'' but I am
stuck on trying to
build the tools.

I initially received the following error (with several previous warnings about 
redefinition):-

/root/xen/xen-4.1.0/tools/ioemu-qemu-xen/net.h:110:1: warning: this is the 
location of the previous definition
In file included from /root/xen/xen-4.1.0/tools/ioemu-qemu-xen/audio/audio.h:27,
                 from /root/xen/xen-4.1.0/tools/ioemu-qemu-xen/net.c:30:

prototype for ‘slirp_output’
/root/xen/xen-4.1.0/tools/ioemu-qemu-xen/net.c: In function ‘slirp_receive’:


I managed to find the missing header file and put a soft link in. No idea why it
would need it, though and I wasn''t convinced it would help.

ln slirp/libslirp.h libslirp.h -s


Now it compiles a little further on, but then I receive this:- 

/config-host.h:20:1: warning: "DEFAULT_NETWORK_DOWN_SCRIPT" redefined
In file included from /root/xen/xen-4.1.0/tools/ioemu-qemu-xen/net.c:25:

‘restrict’
/root/xen/xen-4.1.0/tools/ioemu-qemu-xen/libslirp.h:8: error: invalid use of 
‘restrict’

Does anyone have any suggestions on how to proceed?

Thanks in advance,

Ian.
