I assume you are actually looking at 
http://make.mad-scientist.us/autodep.html

In contrast to Mark's response, I had very little trouble 
incorporating Paul's autodep and multi-architecture suggestions into 
my build process.  The rule you posted is very similar to what I use. 
 In my case the source code is C, not C++.

%$(O) : %$(C)
        $(CC) $(CFLAGS) $(CPPFLAGS) $(TARGET_ARCH) -c -MD -o $@ $<
        @cp $*.d $*.P; \
        sed -e 's/#.*//' -e 's/^[^:]*: *//' -e 's/ *\\$$//' \
                -e '/^$$/ d' -e 's/$$/ :/' < $*.d >> $*.P; \
        rm -f $*.d


Did you look at the dependency file that was generated?  Does it look 
correct?  Did you remember to include it in the Makefile?

-include $(SRCS:.c=.P)
