Question

我正在尝试在Emacs 24.3中设置CEDET 2.2以使用"A gentle introduction to cedet"为我提供自动完成功能，但它并不完全希望以我想要的方式工作。

首先，我尝试使用CEDET自己的完成，但是那个没有提供“弹出菜单”，只有它可以找到的第一个完成，并且没有办法循环。然后我安装了自动完成包，并按照the page中的描述进行设置。这也行不通 - 自动完成崩溃auto-complete error: (void-variable ac-source-semantic)。 ac-source-gtags也是如此。

这是不可能的，因为目前有错误的CEDET，还是我错误配置了它？

Answer 1

配置CEDET是一个巨大的痛苦（我花了几个月的时间才能在现有项目中进行跳转到定义和自动完成工作）。

所以你肯定可能错误配置了CEDET，因为它很难做到正确，我会在这里留下我的配置供你查看，但这实际上取决于你的项目并且是愚蠢的挑剔。
