dependency problem

[Bhaskar G]

Hi All,

Sorry for the incomplete question. I
have src/bg.c and src/bg1.c.
src/bg2.c doenot exist. So when I run
gmake I expect the error message "make: *** No rule to make target
`src/bg2.o', needed by `bg.a'.  Stop."

not  "cc src/bg.o src/bg1.o
src/bg2.o -o bg.a
cc: src/bg2.o: No such file or directory
make: *** [bg.a] Error 1"

Thanks & Regards,
Bhaskar

Hi All,

The following makefile results in the
below said behaviour. This is true for both gmake 3.80 and gmake 3.81 on
RHEL.

SRCS=src/bg.c src/bg1.c src/bg2.c
OBJS=$(SRCS:.c=.o)


bg.a: $(OBJS)
        $(CC) $(OBJS)
-o bg.a

$(OBJS):makefile

/tmp/bg/objs/%.o:%.c
        mkdir -p
$(dir $@)
        $(CC) -c
-o $@ $<

:-)) gmake
cc src/bg.o src/bg1.o src/bg2.o -o bg.a
cc: src/bg2.o: No such file or directory
make: *** [bg.a] Error 1
address@hidden [ /tmp/bg ]

Where as commenting the line $(OBJS):makefile
results in another behaviour. 

:-)) cat makefile
SRCS=src/bg.c src/bg1.c src/bg2.c
OBJS=$(SRCS:.c=.o)


bg.a: $(OBJS)
        $(CC) $(OBJS)
-o bg.a

#$(OBJS):makefile

/tmp/bg/objs/%.o:%.c
        mkdir -p
$(dir $@)
        $(CC) -c
-o $@ $<


:-)) gmake
make: *** No rule to make target `src/bg2.o',
needed by `bg.a'.  Stop.

How do I get the second behaviour with the first implementation.

Thanks in advance for you help.

Thanks & Regards,
Bhaskar
