gnu make - Makefile command modification -



gnu make - Makefile command modification -

i modify makefile command:

-rm -f $(objs) -rm -f $(objs:.o=.mod)

the first removes filenames.o , sec removes filenames.mod. however, modify sec such get: mod_filenames.mod, i.e., add together string "mod_".

i tried: -rm -f mod_$(objs:.o=.mod), affected first file in list. i'm jet guessing here. if suggest wide site such programming explained, grateful.

gnu create manual.

there gnu create unleased book , gnu create standard library.

see 8.3 functions file names of manual, can utilize $(addprefix ...) (there other ways) get:

-rm -f $(objs) -rm -f $(addprefix mod_,$(objs:.o=.mod))

it improve utilize $(rm) (it's rm -f):

-$(rm) $(objs) -$(rm) $(addprefix mod_,$(objs:.o=.mod))

makefile gnu-make
