Re: [Xen-users] Kernel build help

[Mark Williamson <mark.williamson@xxxxxxxxxxxx>]

You need to run *all* the make commands in the Linux directory with ARCH=xen, 
not just the configure (the Linux build system doesn't remember what arch you 
configured for - you get the same problem building UML with ARCH=um).

Cheers,
Mark
