wildcard - Create rule in makefile for just a set of files -

i writing makefile, , want use generic rule wildcards, like

%: bkp/%     cp $< $@ 

but wanted rule valid few specific files. wanted define variable list, example

file_list = foo.c bar.c zzz.c

and configure rule valid files listed in variable. how do that?

you want static pattern rule:

file_list = foo.c bar.c zzz.c  $(file_list): %: bkp/%         cp $< $@ 

the syntax similar implicit pattern rule using. , yes, it's safer (more predictable).
