Hi Anthony,
currently QEMU 1.1 doesn't compile virtfs correctly on Ubuntu:
qemu/hw/9pfs/virtio-9p-handle.c: In function ‘handle_update_file_cred’:
qemu/hw/9pfs/virtio-9p-handle.c:66:58: error: ‘AT_EMPTY_PATH’ undeclared (first
use in this function)
qemu/hw/9pfs/virtio-9p-handle.c:66:58: note: each undeclared identifier is
reported only once for each function it appears in
qemu/hw/9pfs/virtio-9p-handle.c: In function ‘handle_lstat’:
qemu/hw/9pfs/virtio-9p-handle.c:87:34: error: ‘AT_EMPTY_PATH’ undeclared (first
use in this function)
qemu/hw/9pfs/virtio-9p-handle.c: In function ‘handle_symlink’:
qemu/hw/9pfs/virtio-9p-handle.c:314:62: error: ‘AT_EMPTY_PATH’ undeclared
(first use in this function)
qemu/hw/9pfs/virtio-9p-handle.c: In function ‘handle_link’:
qemu/hw/9pfs/virtio-9p-handle.c:337:45: error: ‘AT_EMPTY_PATH’ undeclared
(first use in this function)
qemu/hw/9pfs/virtio-9p-handle.c: In function ‘handle_chown’:
qemu/hw/9pfs/virtio-9p-handle.c:373:58: error: ‘AT_EMPTY_PATH’ undeclared
(first use in this function)
a patch was sent on the 24th of Feb to fix the issue (also see below):
http://marc.info/?l=qemu-devel&m=133011313912147
Even though it is not particularly pretty, in the absence of better
alternatives it should probably be applied.
Cheers,
Stefano
