Hi bug-make, It appears that if there are no normal prerequisites, $< will ignore any order-only prerequisites.
This is not the behavior I expected, and I could not find documentation describing this behavior. Possibly relevant documentation: https://www.gnu.org/software/make/manual/make.html#index-_0024_003c https://www.gnu.org/software/make/manual/make.html#Prerequisite-Types Below is a sample Makefile that demonstrates this unexpected behavior. Thanks! -Parke ---- $ cat Makefile main: message foo bar foo: Makefile bar: | Makefile foo bar: @ echo $@ $< message: @ echo @ echo expected output: @ echo @ echo foo Makefile @ echo bar Makeflie @ echo @ echo actual output: @ echo $ make expected output: foo Makefile bar Makeflie actual output: foo Makefile bar _______________________________________________ Bug-make mailing list Bug-make@gnu.org https://lists.gnu.org/mailman/listinfo/bug-make
