[I suppose that you want to write a long list of words separated by comma on multiple lines, the same as with space separated word lists; for a simple assignment, you can just do it with var = a,b,c]

I don't think that's possible with the standard make; with GNU make (the default on linux), you can use the subst() function for that:

$ cat Makefile

list = first,second,

    third,fourth,

    fifth,sixth



e :=

c := ,

list := $(subst $c $e,$c,$(list))



list:; echo $(list)

$ make

echo first,second,third,fourth,fifth,sixth

first,second,third,fourth,fifth,sixth

If you're using GNU make a better approach would be to the define the list as space-separated, and transform it to comma-separated later on:

$ cat Makefile

words = first     second 

        third     fourth 

        fifth     sixth



e :=

c := ,

clist = $(subst $e $e,$c,$(strip $1))



words:; echo $(call clist,$(words))



$ make

echo first,second,third,fourth,fifth,sixth

first,second,third,fourth,fifth,sixth
