Follow-up Comment #2, bug #27714 (project make): i didnt think it a race condition because the original test case had a fairly lengthy $(shell) code and the targets always ran in the same order (and obviously only one cpu at a time -- the other cpus stayed idle) using sleep shows that it is indeed a make bug. i see one target show up every 10 seconds: $ cat makefile t = 0 a b c 1 d e f 2 g h i 3 j k l 4 m n o 5 p q r 6 all: $(t) ; @echo $(t): ; @printf $@ $(shell sleep 10) $ make -f makefile <10 seconds>0<10 seconds>a<10 seconds>b............ _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?27714> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
