Emacs語義自動完成顯示錯誤？

Question

我使用emacs語義自動完成C語言結構，但是當我標記“>”（消息->）時，它顯示錯誤“無法分析語義不支持的緩沖區”。

Google很多次了，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()

您使用的是過時的CEDET。 只需更新到最新的Emacs，或至少更新到24.3。 然后您可以使用零配置進行測試：

emacs24.3 -Q ~/test.c

Mx semantic-mode 。 此后， semantic-ia-complete-symbol將彈出相應的彈出窗口。
