indeed. I believe you have found a bug, and I believe it is
desirable to fix it.
Though I'm not able to write a patch right now, I can write down some
hints: perhaps they will inspire someone to contribute a patch. ;-)
First, let's start with a completely different example:
wow_SOURCES = boo.cc baux.h bleah.zz
.zz.cc:
cp $< $@
Then the generated Makefile.in contains:
am_wow_OBJECTS = boo.$(OBJEXT) bleah.$(OBJEXT)
wow_OBJECTS = $(am_wow_OBJECTS)
Why? Obviously, Automake knows there is a .cc.o rule, which results
in boo.o. Automake also knows there is no rule to compile *.h to an
object file, so there is no baux.o in the list.
Most interestingly, Automake is able to discover that *.zz will be
eventually compiled into *.o, via a *.cc file.
Look at the procedure derive_suffix in automake/automake.in.
For example, derive_suffix('.zz', '$(OBJEXT)') evaluates to '.cc'.
So back to your example:
I believe Automake knows foo.cc is the last step before foo.o, and I
believe the code should be fixed to use foo.cc instead of foo.x in
the `aaa-foo.o' rule.
If you are willing to make a first iteration of the patch, I believe
it would be welcome. The next step would be to run "make check" with
that patch.
Hope this helps,
Stepan
