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'.

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

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

At the moment, all of them. Automake 2.0 (currently a work in progress if you check out the right branches in git) requires GNU make, for more compact makefiles at the expense of ditching portability to other arcane makes, now that GNU make is more likely to be easily obtained on modern systems. But automake 1.x still tries as hard as possible to produce Makefiles portable to all common make implementations, as long as your Makefile.am doesn't add non-portable code to be passed through to Makefile. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3266 Virtualization: qemu.org | libvirt.org
