我正在尝试使用"A gentle introduction to cedet"在Emacs 24.3中设置CEDET 2.2，以便为我提供自动补全功能，但是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自己的完成功能，但是该功能没有提供“弹出菜单”，只能提供它可以找到的第一个完成功能，并且无法循环浏览。然后，我使用软件包安装了自动完成功能，并按照the page上的说明进行设置。这也行不通-自动完成崩溃时显示auto-complete error: (void-variable ac-source-semantic)。 ac-source-gtags也是如此。
难道是因为CEDET当时存在错误，还是我配置错误？
最佳答案
配置CEDET非常麻烦(在现有项目中花了几个月的时间才能获得跳转到定义和自动完成的功能)。
因此，您肯定可能配置了CEDET，因为很难正确配置，我将在这里保留我的配置供您浏览，但这实际上取决于您的项目，而且很愚蠢。
