The real pain is when not all of the files have changed and you check
in only those that did. This can cause an unwanted auto* rebuild.
I've taken to checking everything in at once whenever one thing
changes with:
cvs ci -f Makefile.am configure.in aclocal.m4 Makefile.in configure
This preserves the proper timestamp/dependency order (at least for me).
First: use a recent automake (1.9.x) that supports the
AM_MAINTAINER_MODE macro, and use that in your configure.ac file. This
will turn off the automatic dependency checking/regeneration of the
Makefile/configure/etc scripts unless you explicitly ask for them (using
configure --enable-maintainer-mode). As a general rule, you don't want
maintainer mode enabled. It was stupid of them to make it the default
behavior but at least it's possible to turn it off now.
One more note - it will make your lives easier if you standardize on a
single version of each tool, so that when you check in newly generated
files the diffs will be small and meaningful. Otherwise you get a lot of
noise, as Andrew already pointed out.
In the past we had things set up so that only a single maintainer was
permitted to regenerate and check in configure script and associated
files, to avoid the issue of having many tool versions in use. Also
there were fixes in our blessed tool versions that the upstream
maintainers hadn't rolled out yet, so we had to keep tarballs of the
specific tools available for download as well.
I think we still have a minor patch in our autoconf tool that the
upstream guys haven't adopted yet - redirecting stderr from the conftest
programs into the logfile instead of /dev/null (which stock autoconf
does), so that it's actually possible to diagnose why a config test
fails. It never fails to amaze me how incredibly un-useful these tools
are out of the box, and how long it takes to get them fixed.
