I compile the QEMU source download from qemu.git (http://git.qemu.org/git/qemu.git) on 4-9-2013, errors reported as below,

'vring_avail_event' and 'vring_need_event' defined in /linux-headers/linux/virtio_ring.h, are not available in vring.c ?

Please send the log of "make V=1".

The log of "make V=1" is identical with that of "make", shown as below,

I'm seeing the same failure. It turns out that linux-headers/linux/virtio_ring.h
is not being referenced, but rather /usr/include/linux/virtio_ring.h, which in
my case (and presumably yours as well) is not as recent and doesn't have
vring_avail_event() and vring_used_event().

I don't need the errors, I need the compiler command line.
