NTEmacsビルド(24.5 その2)

• MSYS2.html

の通りにインストール

GNU ミラーサイト 例えば、ftp://ftp.ring.gr.jp/pub/GNU/emacs/ からダウンロードする。

(今回、上記にはまだ置かれていなかったので http://ftp.gnu.org/gnu/emacs/ からダウンロードした)

• emacs-24.5.tar.gz を任意のディレクトリに展開する

$ export MSYSTEM=MINGW32
$ export PKG_CONFIG_PATH=/mingw32/lib/pkgconfig

何も指定しない場合は下記でよいのだが、

$ ./configure

/etc/PROBLEMS に、Emacs終了時にクラッシュする不具合についての記載がある。

\** Emacs crashes when exiting the Emacs session

This was reported to happen when some optional DLLs, such as those
used for displaying images or the GnuTLS library or zlib compression
library, which are loaded on-demand, have a runtime dependency on the
libgcc DLL, libgcc_s_dw2-1.dll.  The reason seems to be a bug in
libgcc which rears its ugly head whenever the libgcc DLL is loaded
after Emacs has started.

One solution for this problem is to find an alternative build of the
same optional library that does not depend on the libgcc DLL.

Another possibility is to rebuild Emacs with the -shared-libgcc
switch, which will force Emacs to load libgcc_s_dw2-1.dll on startup,
ahead of any optional DLLs loaded on-demand later in the session.

よって、これを回避する為、下記のオプションをつける。

-shared-libgcc 以外のオプションは、オプション無しで configure を実行した際に Makefile に記述されるオプションを元にしている。

$ ./configure CFLAGS="-O2 -shared-libgcc" --without-dbus

Configured for `i686-pc-mingw32'.

MSYS2がインストールされていないPCでも動作可能にする為、依存するDLLを emacsのexeファイルがあるフォルダにコピーする。

• C:\msys32\mingw32\bin から
  • libgcc_s_dw2-1.dll -shared-libgcc を指定した場合には不要・・・かと思ったが必要なようだ。無いとemacs自体が起動できない。
  • libgdk_pixbuf-2.0-0.dll
  • libgif-7.dll
  • libglib-2.0-0.dll
  • libgnutls-28.dll
