Re: When some files need special compilation flags, ...

[Fabrice GIRARDOT]

You may try this way :

You can define variables which name is build with part
of a source filename :


SPECIAL_FLAG_file1.c = -DSOME_FLAG
SPECIAL_FLAG_file2.c = -DOTHER_FLAG

%.o: %.c
        $(CC) -c $< $(SPECIAL_FLAG_$(notdir $<)) -o $@


When a file does not need any special flag, then
$(SPECIAL_FLAG_$<) would evaluate to an empty string.
