[Xen-devel] Building unmodified_drivers fails in unstable x64 XEN

["Nowatzki, Thomas L" <Thomas.Nowatzki@xxxxxxxxxx>]

Per the instructions in the README I am trying to build the paravirtualized drivers from unmodified_drivers.  However, it doesn't seem to work in the latest unstable XEN version.  I am running SLES10 x64 version.  Quite possibly I am doing the build incorrectly although it seems quite straight forward:

SLESx64:/xen-unstable.hg/unmodified_drivers/linux-2.6 # ./mkbuildtree x86_64
SLESx64:/xen-unstable.hg/unmodified_drivers/linux-2.6 # make -C /usr/src/linux  M=$PWD modules
make: Entering directory `/usr/src/linux-2.6.16.21-0.8'
Makefile:450: .config: No such file or directory

  WARNING: Symbol version dump /usr/src/linux-2.6.16.21-0.8/Module.symvers
           is missing; modules will have no dependencies and modversions.
