I am not sure why this is needed. The .. here is the path from foo-softmmu/ to the build root. QEMU's build system is only one-level recursive, something like foo-softmmu/hw/virtio/virtio.c is compiled from foo-softmmu/ (whose Makefile is Makefile.target) and thus the path needs to be relative from foo-softmmu/. It need not be relative to foo-softmmu/hw/virtio. Paolo
