This can happen if the machine crashes while you were compiling. Its timestamp is then ``recent'', so make won't rebuild it. (That's why make normally deletes the target under work if you hit ^C, unless you've marked it as .PRECIOUS in the Makefile.) j@uriah 691% grep ^vm_object_reference /sys/vm/*.c /sys/vm/vm_object.c:vm_object_reference(object) So watch out for vm_object.o. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
