I'm not exactly sure what the purpose of this is, but it doesn't look like portable code, so probably not something Automake should be generating. But don't let that stop you. You can add basically anything you'd like, including the above rules, to your project's Makefile.am and Automake will copy it through to the output. Cheers, Nick

I=E2=80=99m using automake 1.15.1 on Fedora 28.
I changed my AM_INIT_AUTOMAKE() to include subdir-objects.
As soon as I did this, I started seeing failures like:
make[2]: Entering directory '/home/philipp/git/snt/libntp'
Makefile:902: warning: overriding recipe for target =
'../lib/isc/pthreads/.dirstamp'
Makefile:802: warning: ignoring old recipe for target =
'../lib/isc/pthreads/.dirstamp'
Makefile:905: warning: overriding recipe for target =
'../lib/isc/pthreads/.deps/.dirstamp'
Makefile:805: warning: ignoring old recipe for target =
'../lib/isc/pthreads/.deps/.dirstamp'
Makefile:964: ../lib/isc/unix/.deps/time.Po: No such file or directory
make[2]: *** No rule to make target '../lib/isc/unix/.deps/time.Po'. =
Stop.
make[2]: Leaving directory '/home/philipp/git/snt/libntp'
After some head-scratching, I noticed:
$ find . -name '$*' -print
./sntp/tests/$(top_builddir)
./tests/ntpd/$(srcdir)
./libntp/$(srcdir)
$=20
and root-caused this to here:
# Extract the definition of DEPDIR, am__include, and am__quote
# from the Makefile without running 'make'.
DEPDIR=3D`sed -n 's/^DEPDIR =3D //p' < "$mf"`
test -z "$DEPDIR" && continue
am__include=3D`sed -n 's/^am__include =3D //p' < "$mf"`
test -z "$am__include" && continue
am__quote=3D`sed -n 's/^am__quote =3D //p' < "$mf"`
# Find all dependency output files, they are included files with
# $(DEPDIR) in their names. We invoke sed twice because it is the
# simplest approach to changing $(DEPDIR) to its actual value in the
# expansion.
for file in `sed -n "
s/^$am__include $am__quote\(.*(DEPDIR).*\)$am__quote"'$/\1/p' =
<"$mf" | \
sed -e 's/\$(DEPDIR)/'"$DEPDIR"'/g'`; do
# Make sure the directory exists.
test -f "$dirpart/$file" && continue
fdir=3D`$as_dirname -- "$file" ||
=E2=80=A6
as_dir=3D$dirpart/$fdir; as_fn_mkdir_p
# echo "creating $dirpart/$file"
echo '# dummy' > "$dirpart/$file"
done
Problem is, what happens if the line you=E2=80=99ve read looks like:
include $(srcdir)/../lib/isc/unix/$(DEPDIR)/time.Po
after mangling that, we end up with =
file=3D$(srcdir)/../lib/isc/unix/.deps/time.Po which is obviously wrong.
Yes, $(DEPDIR) needs to be substituted out=E2=80=A6 but so does every =
other variable potentially, including $(srcdir) =E2=80=A6
Either subdir-objects should handle ALL possible expansions (might =
require some hackery and recursively calling Makefile on each line to do =
expansions)=E2=80=A6 or configure should make sure that $file doesn=E2=80=99=
t match /\$(.*)/ indicating that it contains unexpanded variables=E2=80=A6=
and maybe suggest using @variable@ substitutions instead if possible.
If you want to reproduce this yourselves, grab the ntp-4.8.2p11 tarball =
and change configure.ac and sntp/configure.ac to use =
AM_INIT_AUTOMAKE([=E2=80=A6 subdir-objects =E2=80=A6]) instead.
Run:
./bootstrap
./configure --with-crypto --with-threads --disable-silent-rules =
--disable-local-libevent
and you=E2=80=99ll see the broken behavior.
Thanks,
-Philip
