charset="us-ascii" Content-Transfer-Encoding: 7bit Hello automakers. Currently, the Automake-generated rebuild rules[1] invoke automake with some command-line options derived from arguments given to AM_INIT_AUTOMAKE. [1] For more info, see: <http://www.gnu.org/software/automake/manual/html_node/Rebuilding.html> For example, putting `foreign' in AM_INIT_AUTOMAKE generates remake rules that rebuild outdated Makefile.in files using "$(AUTOMAKE) --foreign"; similarly, `no-dependencies' in AM_INIT_AUTOMAKE generates remake rules that rebuild outdated Makefile.in files using "$(AUTOMAKE) --ignore-deps". This semantic clearly breaka remake rules in the (admittedly unlikely and corner-case) situation when e.g., `foreign' or `no-dependencies' arguments are removed from the call to AM_INIT_AUTOMAKE (see attached testcases, which should work with latest master -- v1.11-564-g635a250). Let's now see explicitly and in detail how this happens (for the case of the `foreign' option) ... -*-*- First, the developer creates a configure.ac that contains: AM_INIT_AUTOMAKE([foreign -Wall]) He runs aclocal, autoconf and automake; this generates a Makefile.in that contains rebuild rules which call automake as "$(AUTOMAKE) --foreign". He then runs configure, and those rebuild rules end up verbatim in the generated Makefile. At this point, the developer decides he wants to switch to the 'gnu' strictness for his package; since 'gnu' is indeed the default strictness, he simply modifies the AM_INIT_AUTOMAKE call to read: AM_INIT_AUTOMAKE([-Wall]) and then run "make", trusting that the rebuild rules in Makefile will do all the required updates for him. But alas, the existing rebuild rules in the Makefile will call "$(AUTOMAKE) --foreign", and so, since no strictness is explicitly specified in AM_INIT_AUTOMAKE, the 'foreign' strictness will still be used. -*-*- Cooking up a patch to fix this problem shouldn't be difficult; but such a patch would need to touch the same parts of the code modified by the pending patch series "Explicit warning levels must always take precedence over those implied by the strictness": <http://lists.gnu.org/archive/html/automake-patches/2010-12/msg00139.html> Thus I will wait for that series to be applied first, to spare me useless conflicts when merging and/or rebasing.

I agree that this is a bug. Question is, does removing the arguments break other, legitimate uses? Or was this functionality purely added at a time before automake could trace configure.ac macros? The tests might suffer from the trace caching bug as well, haven't checked. Thanks, Ralf

Thanks for the research. It seems we should move away from this then. Only thing I really wonder is why Alexandre (or Akim) didn't do that at the time autoconf tracing started to be used. It seems like such an obvious move to make that it makes me unsure we're overlooking something. > > The tests might suffer from the trace caching bug as well, haven't > > checked. > > > Am I missing something, or is this a quite serious bug of autom4te? Well, it seems to work fine when we ensure configure.ac is strictly newer than the files in autom4te.cache. But I wanted to avoid sleeping. So I tried --force, but that failed. The two things I still need to check are: do 'aclocal --force' and 'automake --force' need to pass --force to 'autom4te --trace' resp. 'autoconf --trace' and do things work out then? Cheers, Ralf
