ていへんかけるたかさわるに

MacPorts のアップデートを行って, Emacs HEAD のコンパイルをする.
OS X El Capitan 上での作業である.

$ sudo port selfupdate
$ sudo port -uv upgrade outdated
$ cd ~/src/emacs.HEAD/emacs
$ ./autogen.sh
$ ./configure --with-ns --without-x
$ git pull git://git.sv.gnu.org/emacs.git
$ make bootstrap

ところが make bootstrap を実行した段階で,

configure: creating ./config.status

make: *** [Makefile] Error 1

と立て続けにエラーが出てコンパイルが進まない.
調べるだけの気力は殆ど無かったが, 一応メッセージを読んでみる.
そうしたら全部同じ類のエラーだった. 発生しているのは, 以下の形式のエラーである.

config.status: creating ...
dyld: Library not loaded: /opt/local/lib/libreadline.7.dylib
  Referenced from: /usr/local/bin/gawk
  Reason: image not found

これくらいだったら何とかなるかも知れない.

GNU awk: /usr/local/bin/gawk (これは MacPorts によってインストールされたもので /opt/local/bin/gawk にリンクされている) が呼び出された時点で, ライブラリー /opt/local/lib/libreadline.7.dylib が存在しないためにエラーとなっているようだ.

実際にディレクトリー /opt/local/lib の readline 関連のライブラリーを確認すると,

$ ls -1 /opt/local/lib/libreadline.*
/usr/local/lib/libreadline.8.0.dylib
/usr/local/lib/libreadline.8.dylib
/usr/local/lib/libreadline.a
/usr/local/lib/libreadline.dylib

と出力され, 確かに /opt/local/lib/libreadline.7.dyllib は存在しない.

そこで

$ sudo port upgrade gawk

を実行して GNU awk を El Capitan 対応の最新版にアップグレードする.

$ port installed gawk
  gawk @4.2.1_0                 # <- old version.
  gawk @4.2.1_2 (active)        # <- newly installed version.

GNU awk の新しいバージョンがインストールされたことが確認できる. 結果として, これで GNU awk は正常に動作するようになった.

Emacs のコンパイルに戻って

$ ./autogen.sh
$ ./configure --with-ns --without-x
$ git pull git://git.sv.gnu.org/emacs.git
$ make bootstrap
$ make check
$ make install

によってコンパイルを行う. エラー無しに終わる.

動作も確認できたのでシステムへのインストールを行って Emacs HEAD のアップデートは終了した.

そう言えば, Emacs を最新版に上げたのは今年になって初めてある.

やっと, こういう初歩のシステム管理ができるようになった, と言っていいのだろうか. まだ自信は無いが.
