[Xen-users] how to compile a xen kernel (on debian testing)?
Hello,
I was wondering how do other people using debian build the xen kernels
form source on a debian testing system?
I am using a Debian testing system. I have installed the xen package and
it works nicely. However, I would like to change some options in the xen
kernels (like adding IPv6) and compile them myself. I have downloaded
the stable xen release
(http://www.cl.cam.ac.uk/Research/SRG/netos/xen/downloads/xen-2.0.7-src.tgz)
and tried:
make kernels
make CC=gcc-3.4 kernels
make CC=gcc-3.3 kernels
and with all I ended up at
[snip]
CC arch/xen/i386/kernel/process.o

An earlier message on this list says for redhat using gcc-3.2 helped.
But I can't find a gcc-3.2 package for debian. Anybody knows where to
get it?
I have also tried to build the debian xen package from source. AFAIK,
this one uses the 2.0.6 xen release. It sets the Makefile CC to gcc-3.4,
but it also tries to use kenel-source-2.6.11 and
kernel-patch-debian-2.6.11 packages, which again I cannot find anywhere.
Using dpkg-buildpackage -d, I got again hit by the same problem:

I guess the debian patch for 2.6.11 does some magic so that it compiles
with gcc-3.4, but I'm not sure how to get that patch.
Trying to compile the testing version of xen, I got a similar problem:
$ make CC=gcc-3.4 kernels
[snip]
CC arch/xen/i386/kernel/process.o
arch/xen/i386/kernel/process.c: In function `cpu_idle':
arch/xen/i386/kernel/process.c:118: warning: unused variable `cpu'
{standard input}: Assembler messages:
{standard input}:910: Error: suffix or operands invalid for `mov'
{standard input}:911: Error: suffix or operands invalid for `mov'
make[4]: *** [arch/xen/i386/kernel/process.o] Error 1
[snip]
I have also tried the unstable version. This one compiles without
problems and I could also "make install". But then I got various
problems later on the way and in general, I would prefer to run the
stable version.
Thanks,
Matus
