Could anyone identify what going wrong here or how can i fix this error?

I´ve followed this howto building XEN: http://www.howtoforge.net/debian_etch_xen_3.1_p5

Maybe some depencys are not correct?

THanks for helping me!

Greetings Armin

I don't know what's wrong with this except that I've noted cc1: warnings being treated as errors in your message and the xen build process is not warnings free yet.
What I propose is the following:
Beeing on debian the safest way is to install via debs, so I would recommend to search packages.debian.org for xen-hypervisor with distribution sid, download the source package, unpack it with dpkg-source -x .....dsc, then cd to the created directory and dpkg-buildpackage -rfakeroot.
This way I was able to compile xen on my etch box.

Good Luck!
