在CEDET中自动完成？

Question

我试图在Emacs 24.3中设置CEDET 2.2来为我提供自动完成，使用"A gentle introduction to cedet"，但它并不完全想按照我希望的方式工作。

首先，我尝试使用CEDET自己的完成，但那个不提供“弹出式菜单”，只有第一次完成它才能找到，并且没有办法循环。然后我安装了自动完成软件包，并将其设置为the page中描述的那样。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的错误，或者我错误配置了它，这仅仅是不可能的吗？

Answer 1

配置CEDET是一个巨大的痛苦（花了几个月的时间才得到跳转到定义和自动完成在现有项目中工作）。

所以你当然可能错误配置了CEDET，因为它很难得到正确的结果，我将把我的配置留在这里让你查看，但这取决于你的项目，而且很愚蠢。
