Emacs語義自動完成顯示錯誤？

Question

我使用emacs語義來自動完成C語言結構，但當我標記「>」（Message->）時，它顯示錯誤「無法分析不受語義支持的緩衝區」。

谷歌很多次，我沒有找到任何解決方案。

調試消息：

Debugger entered--Lisp error: (error "Cannot analyze buffers not supported by Semantic") 
signal(error ("Cannot analyze buffers not supported by Semantic")) 
error("Cannot analyze buffers not supported by Semantic") 
semantic-analyze-current-context() 
byte-code("\301 \210^H\203^V^@\302 \204^Q^@\303 \203^V^@\304^H\305\"\210\306\207" [semantic-current-input-throw-symbol semantic-analyze-current-c$

您正在使用可怕的過時CEDET。 只需更新到最新的Emacs，或至少到24.3。 然後你可以用零配置進行測試：

emacs24.3 -Q ~/test.c 

M-Xsemantic-mode。之後，semantic-ia-complete-symbol將彈出 相應的彈出窗口。
