我正在尝试在 Emacs 24.3 中设置 CEDET 2.2 来为我提供自动补全功能，使用“对 cedet 的温和介绍”，但它并不完全希望按照我想要的方式工作。

首先，我尝试使用 CEDET 自己的补全，但是那个不提供“弹出菜单”，只有它可以找到的第一个补全，并且无法循环。然后我安装了带有包的自动完成功能并按照页面上的描述进行设置。这也不起作用 - 自动完成崩溃说auto-complete error: (void-variable ac-source-semantic). ac-source-gtags 也是如此。

由于目前 CEDET 有问题，这是不可能的，还是我配置错误？

配置 CEDET 是一件非常痛苦的事情（我花了几个月的时间才在现有项目中实现跳转到定义和自动完成）。

因此，您当然可能错误地配置了 CEDET，因为它很难正确配置，我将把我的配置留在这里供您查看，但这确实取决于您的项目，而且非常挑剔。
