Can I change a variable inside a rule?

[Martin Mensch]

Hello,

 

is there a way to change a variable inside a rule?

Maybe like this:

 

LIST = a.c b.c c.c d.c

 

%.c:

# creating %.c

here add $@ to the variable FILES, but simply FILES += $@ doesn't work here

 

end:

    @echo files compiled: $(FILES)

 

all: $(LIST) end

 

Thank you for any help

 

Martin
