make problem: multiple taget patterns

Tue Jul 1 16:41:00 GMT 1997

Hello all,
I'm having a problem with the GNU make from b18...
My makefiles use gcc to build .d files and then include them into the
make. I also use pattern matching to build the object files.
Here's a cut from the makefiles:
%.o:	%.c
	$(GREPSTRING)
	$(CC) $(CFLAGS) $(INC) -c $< -o $@
%.o:	%.s
	$(GREPSTRING)
	$(CC) $(CFLAGS) $(INC) -c $< -o $@
%.o:	%.cxx
	$(CC) $(CFLAGS) $(INC) -c $< -o $@
%.d:	%.cxx
	(trap 'rm $@' 2; $(ECHO) "$@ " | tr -d '012円' > $@ ; \
	$(DCC) $(CFLAGS) $(INC) -M -DDEPCHK $< >> $@ || rm $@ )
%.d:	%.c
	(trap 'rm $@' 2; $(ECHO) "$@ " | tr -d '012円' > $@ ; \
	$(DCC) $(CFLAGS) $(INC) -M -DDEPCHK $< >> $@ || rm $@ )
include $(OBJS:.o=.d)
So my .d files end up looking something like this:
hdrgen.d hdrgen.o: hdrgen.c hdrgen.h (more random header files)
Now when I run make, it complains about the multiple header files (I
think)
hdrgen.d:1: *** multiple target patterns. Stop.
gmake: *** [apps] Error 2
gmake: *** [all] Error 2
gmake: *** [tools] Error 2
Compilation exited abnormally with code 2 at Tue Jul 01 16:09:06
I've manually edited my .d file to this
hdrgen.o: hdrgen.c
which works, but as soon as I add a header file dependency, it fails
hdrgen.o: hdrgen.c hdrgen.h
BTW, this all works fine with make v3.70 on UNIX
Anybody of any insights?
Thanks,
Yung Hsien
