Question

遵循emacs-eclim的安装指南后，我想通过“start-eclimd”启动eclimd，但是Mini-Buffer中会弹出以下错误消息。

符号作为变量的值为void：eclimd-port

Eclimd脚本在eclipse中启动时完美无瑕。

在shell中运行脚本会出现以下错误：

您的jvm不支持您安装的eclipse所需的体系结构：-d32

我的Java版本：

java版“1.7.0_21” OpenJDK运行时环境（IcedTea 2.3.9）（7u21-2.3.9-1ubuntu1） OpenJDK 64位服务器VM（版本23.7-b01，混合模式）

这是64位问题吗？

我只想控制emacs或至少脚本中的守护进程。这些行与我的.emacs相关：

;; Eclim - eclipse interface for emacs
(require 'eclim)
(global-eclim-mode)
(require 'eclimd)

Answer 1

我认为eclimd.el文件中有一个错误（〜/ .emacs.d / elpa / emacs-eclim-20140809.207 / eclimd.el）

我为eclimd-port添加了一个defvar，解决了这个问题。（在此报道：https://github.com/senny/emacs-eclim/issues/156）

    (defvar eclimd-port nil
      "The active eclimd port number")

Answer 2

似乎这不是emacs问题。当您在emacs上运行start-eclimd时，它可能使用与从shell运行脚本时相同的上下文来触发进程，在那里您会收到32位与64位错误。

也许您应该尝试修复您的eclim设置，以便当您从shell运行它时，您会得到一个看起来像

的输出

Eclim Server在端口上启动...

This可能会有所帮助。

符号的值作为变量是void：eclimd-port
