More dependencies...

[Patrick Guio]

Refering to my earlier mail today,I have a comment about

.cpp.o:
  source='$<' object='$@' libtool=no \
  depfile='$(DEPDIR)/$*.Po' tmpdepfile='$(DEPDIR)/$*.TPo' \
  $(CXXDEPMODE) $(depcomp) \
  $(CXXCOMPILE) -c -o $@ `test -f $< || echo '$(srcdir)/'`$<

The name of the dependency file is connected to the source file, not the
object file, it should maybe better to build the name with the object file
since the object might have been compiled with different defines flags.

In my case I have a list of sources for a library 

MUDDIR = .
UTILSRC = $(MUDDIR)/argparsing.cpp $(MUDDIR)/integrate.cpp
MUDSRC = $(MUDDIR)/init.cpp $(MUDDIR)/lop.cpp $(MUDDIR)/mudfas.cpp\
$(MUDDIR)/prolon.cpp $(MUDDIR)/qnc.cpp $(MUDDIR)/restrict.cpp\
$(MUDDIR)/restrict_ops.cpp $(MUDDIR)/restrictphi.cpp\
$(MUDDIR)/smooth.cpp $(MUDDIR)/smooth_ops.cpp

This library is compiled in 2d (-DDIM=2) and 3d (-DDIM=3)

and I have 

MUD2DOBJ := $(patsubst %.cpp, %2d.o, $(MUDSRC))
MUD3DOBJ := $(patsubst %.cpp, %3d.o, $(MUDSRC))

$(MUD2DOBJ): %2d.o: %.cpp
  source='$<' object='$@' libtool=no \
  depfile='$(DEPDIR)/$*.Po' tmpdepfile='$(DEPDIR)/$*.TPo' \
  $(CXXDEPMODE) $(depcomp) \
  $(CXXCOMPILE) $(INCLUDES) -DDIM=2 -c -o $@ `test -f $< || echo
'$(srcdir)/'`$<
$(MUD3DOBJ): %3d.o: %.cpp
  source='$<' object='$@' libtool=no \
  depfile='$(DEPDIR)/$*.Po' tmpdepfile='$(DEPDIR)/$*.TPo' \
  $(CXXDEPMODE) $(depcomp) \
  $(CXXCOMPILE) $(INCLUDES) -DDIM=3 -c -o $@ `test -f $< || echo
'$(srcdir)/'`$<

But only '$(patsubst %.cpp, %.Po, $(MUDSRC))' are created.

Sincerely
