Yeah, I was just about to suggests this. However, in general would it be a problem if a mock library would link with say libvirt_utils statically? That way we shouldn't have any dependency problems, should we? Michal -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
