I'm not sure about this specific error, but in general the ceph-client code requires the very latest kernel release from Linus (ie, 2.6.35 now). For older kernels, you need to use the backports branches available in http://git.kernel.org/?p=linux/kernel/git/sage/ceph-client-standalone.git Right now the rbd branch doesn't have a backports equivalent, but you could try to checkout the unstable-backport and merge the rbd branch in and see if it works. Otherwise I believe the rbd branch will be merged into unstable very soon, so you shouldn't have long to wait. :) -Greg On Sun, Aug 1, 2010 at 8:52 PM, Xiaoguang Liu <syslxg@xxxxxxxxx> wrote: > I wanted to build RBD client.
