I'll wait the customary 72 hours before pushing. Thanks. OK, but please remove all the comments about tar unportability in the tests. It's so obvious. ;-) OK done. (and there are probably a dozen other places in the Automake source tree that you'd have to put the comment at as well, for any amount of consistency. I think having one comment, the one that already exists in lib/am/distdir.am, is fully sufficient.) I'm ok with fixing the manual also, although it's usually clear for people still having to use those vendor tars (and inconvenient for the rest). Yes, I'd say we leave the examples in manual untouched. Agreed? OK. Subject: [PATCH] tests: portability fixes in tests on amhello examples * tests/amhello-binpkg.test: Don't use tar xzf too.tag.gz to extract a gzip-compressed tarball, that's unportable to some tar implementations; use the gzip -dc fo.tar.gz | tar xf - idiom instead. * tests/amhello-cflags.test: Likewise. * tests/amhello-cross-compile.test: Likewise. Thanks, Ralf Pushed now. Thanks, Stefano
bug#9026: Supporting $ACLOCAL_PATH?
Hello, On an FHS-style system, all macros are picked up from /usr/share/aclocal. Conversely, on a Stow/Nix-style installation, macros are to be found in /foo/automake/share/aclocal, /bar/guile/share/aclocal, /baz/pkg-config/share/aclocal, etc. It seems to me that the latter calls for user environment-specific settings, which an $ACLOCAL_PATH environment variable would handily support [0]. WDYT? Bruno rightfully noted the importance of having a reproducible way of producing tarballs, and user-specific environment settings appear to go counter this goal. However, there will always be a need for this kind of setting on Stow/Nix-style systems, AFAICS. Thanks, Ludo’. [0] In fact Nixpkgs/NixOS has a wrapper around ‘aclocal’ that does exactly this (see https://svn.nixos.org/repos/nix/nixpkgs/trunk/pkgs/development/tools/misc/automake/builder.sh.)

JFTR, there's a pending patch series by Paolo Bonzini that introduces exactly the feature you're requesting: http://lists.gnu.org/archive/html/automake-patches/2010-11/msg00089.html I'm highly in favor of having the series applied to maint ASAP, but we should wait for Ralf's ACK before doing that (and probably he won't be avaiable this weekend).

Also, it is important for distributors to be able to regenerate the 'configure' file of packages, for a variety of reasons. They can only do so if the tarball contains the _complete_ source code of the configure file, that is, all the .m4 files that were used to create it, except the .m4 files of Automake and Autoconf. Have you ever tried to rebuild the configure file of a package that did not package pkgconfig.m4 or glib.m4? It's a nightmare. Therefore, please don't encourage maintainers to omit nontrivial .m4 files from the tarball. Adding support $ACLOCAL_PATH would do exactly that.

Following your line of thinking, we should also drop the support for the `dirlist' special file then. The fact that a feature can be misused is IMHO not a good reason against its introduction, if it can also be used legitimately and profitably. Also, a conscientious user would anyway add `--install -I m4' to his ACLOCAL_AMFLAGS, so that third-party m4 files would be copied in the local m4 directory (and thus automatically distributed by automake). I say we should instead follow the UNIX practice of giving the user enough rope to hang himself, but advise him not to do so; metaphors aside, this means we should implement $ACLOCAL_PATH, but also vouch your concerns clearly and strongly in the manual (as usual, patches welcome ;-) Regards, Stefano

Hi Stefano, I say we should instead follow the UNIX practice of giving the user enough rope to hang himself, but advise him not to do so This is a good attitude for the many features with which a developer can only harm himself and which cause no harm to others. But with $ACLOCAL_PATH he can harm the freedom of the distributors of his package; I think this requires special consideration.

Hi Stefano,
Also, a conscientious user would anyway add
`--install -I m4' to his ACLOCAL_AMFLAGS, so that third-party m4 files
would be copied in the local m4 directory (and thus automatically
distributed by automake).
Hey, the --install option is something I need to mention in the GNU gettext
documentation. I wasn't aware of it up to now.

* gettext.texi (aclocal): Recommend the use of aclocal's --install
option.
