GNU Emacs 24.3 で el-get を使用して公式の CEDET 2.0 をインストールし、構成しました。コードのジャンプと補完にはうまく機能しますが、Emacs 組み込みの which-function-mode では適切に機能しません。メジャー モードが Java モードの場合、有効な関数が認識されないかのように、Emacs モードの行に [???] が表示されるだけです。しかし、CEDET 構成を削除すると、 which-function-mode はうまく機能します。したがって、問題は公式の CEDET 2.0 に関連していると思います。which-function-mode を手動で有効にしようとしましたが、問題は解決しません。
構成のどこで問題が発生するのかわかりません。
誰でも助けることができますか？ありがとう。
更新: 行 (semantic-mode 1) をコメントアウトしてセマンティックを無効にすると、 which-function-mode が機能します。CEDET ドキュメントを確認したところ、セマンティックは私が行った方法で有効になっています。
