在 ubuntu 上最少安装 emacs24

Question

我需要一个最小的 emacs 24 安装来在虚拟盒子中分发。当我尝试从突触安装 emacs-snapshot 时，我安装了大量的东西，比如 ghostscript 和 imagemagic 以及各种库。我需要他们吗？有没有解决的办法？

我需要一个最小的 emacs 24 安装来在虚拟盒子中分发。当我尝试安装 emacs 时...

我知道那种感觉...当我安装emacs-nox它时可能会超过 100 MB。对于某些资源受限的设备来说，这是不可接受的，例如只有几百 MB 可用存储空间的BeagleBoard或Banana Pro。

您可以使用以下命令获取和解压最新的 emacs（为了配方完整性）：

wget http://mirrors.syringanetworks.net/gnu/emacs/emacs-24.5.tar.gz
tar xzf emacs-24.5.tar.gz 
cd emacs-24.5/

以下是我用于emacs-24.5的配置。它生成了一个 25.4 MB 的二进制文件：

./configure --with-xml2 --with-zlib --without-x --without-sound --without-xpm \
  --without-jpeg --without-tiff --without-gif --without-png --without-rsvg \
  --without-imagemagick --without-xft --without-libotf --without-m17n-flt \
  --without-xaw3d --without-toolkit-scroll-bars --without-gpm --without-dbus \
  --without-gconf --without-gsettings --without-makeinfo \
  --without-compress-install

和：

$ ls -l /usr/local/bin/
total 26648

从源代码构建确实需要编译器和链接器之类的东西，但我还是通过build-essential包安装了它们。唯一缺少的依赖项是ncurses包 ( ncurses-dev)。

即使删除了所有额外的 GUI 内容，您仍然会看到带有超链接的烦人屏幕。但是二进制文件的大小是它的 1/4，所以我称之为胜利。
