Implicit rules and directory names

[René Rebe]

Hi all,

to gain some benefits I convert our Makefiles from recursion to non-recursion 
and using the various "Recursive Make considered harmful" or "Recursive Make 
reloaded" papers on the net.

So far this worked out quite nicely, however I have trouble with multiple 
executables per directory. I would either like an implicit rule, in the form:

$($(X_MODULE)_OUTPUT)/%: %.o $(DEPS)
        @echo '  LINK EXEC $@'
        $(Q)$(CXX) $(CXXFLAGS) $(CPPFLAGS) $(TARGET_ARCH) -o '$@' $^ $(LDFLAGS)

However due to the full patch (I think) this rule does not match, and also if 
I (for testing) modify this to not use pathes it does not use the $(DEPS) and 
ignores the prerequisits.

I fear implicit rules are not intended to be used this way - what also would 
work out is generating a explicit rule for each target like (pseudo code):

foreach x $(X_MODULE_BINARY)
$($(X_MODULE)_OUTPUT)/$(x)%: $(X_MODULE)/$(x).o $(DEPS)
        @echo '  LINK EXEC $@'
        $(Q)$(CXX) $(CXXFLAGS) $(CPPFLAGS) $(TARGET_ARCH) -o '$@' $^ $(LDFLAGS)
endeach

Thoght I find nothing in the make info page to allow such a construct.

Any ideas?
