Autotools - yamanetoshi's diary

こんなのとかこんなのを参照しつつ、unbound-1.0.2 の debian/rules とかログを確認。

build

ログが以下。

 debian/rules build
dh build --before configure
   dh_testdir
libtoolize --force
You should update your `aclocal.m4' by running aclocal.
aclocal
autoheader
autoconf
dh_auto_configure -- \
                --disable-rpath \
                --with-chroot-dir=/var/lib/unbound \
                --with-pidfile=/var/lib/unbound/unbound.pid
checking for gcc... gcc
(以下略

debian/rules によれば確かに上記の順でナニ。aclocal は man によると

automatically generate aclocal.m4 from configure.in

とある。その直前に実行されていると思われる libtoolize が出力していると思われるメセジが微妙に気になりますな。man で確認するに --force は

Replace existing libtool files. By default, `libtoolize' won't overwrite existing files.

との事。具体的に何をどうなのかが微妙なんですが、ヤッてみれば良いのかな。

debian/rules 確認

からナニ。

$ fakeroot debian/rules clean
dh clean
   dh_testdir
   dh_auto_clean
   dh_clean
$

で、順に中身をナニしてみるか。こんどは一つづつ。

$ dh build --before configure
    dh_testdir

$

ざっくり上記のみであれば

config.guess
config.sub
ltmain.sh

が libtoolize --force で作成された模様。上記を元に aclocal 以降で云々、なのでしょうか。

aclocal

という事で次は aclocal

$ aclocal

$

ええと、このタイミングで aclocal.m4 と autom4te.cache が更新されている模様。ちなみに libtoolize の瞬間に debian ディレクトリが touch されているらしい。
# debian の中身に変更は無い、というのが根拠なんですが ...

autoheader

次は autoheader との事。

うーん。この時点で更新されたのは autom4te.cache のみ。このあたりは参照している図面と異なる状態遷移なのかなぁ。ってか、中間ファイルを云々、に見えます。

ここで configure が出力されております。

autom4te とか

微妙。m4 とか全然ワケワカだけに。

で、ここでいきなり clean

してみる。

debian が touch されてる
autom4te.cache は削除
configure はそのまま
aclocal.m4 もそのまま

結局何をしようとしたのかワケワカになりつつあるんですが、微妙な中間ファイルで一層迷路に入りつつあるのでしょうか。
