More dependencies II

[Patrick Guio]

I wonder whether it's actually possible to use depcomp with _LDADD object
files, like object with different compilation flags?
It looks like that the files ~/.deps/*.Po are created while configure is
run when detected in _SOURCES files but not _LDADD.
Sincerely

Patrick

Subject: More dependencies...


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.
