Apacheのqpidをインストールするときに "エラー：変更の意味"

Question

AMQPメッセージを大規模なC++プログラムに統合するために、SUSE Linuxシステムにqpid陽子0.14.0ライブラリをインストールしようとしています。インストールには "cmake"と "make all"が必要です。 『構造体陽子::はdelivery_mode』エラーから 『はdelivery_mode』の意味は」変化を研究する

このことを信じて私をリード：「すべて作る」を呼び出す際に、ビルドは、エラーをスローし、32％に完全取得します構造体と同じ名前を持つコンストラクタ関数を実行する問題である。私は以下のdeliver_modeの構造体宣言を含むよ。私はこれらのライブラリをインストールするために得ることができる方法についてどのような考えは？ありがとう！

namespace proton { 

/// The message delivery policy to establish when opening a link. 
/// This structure imitates the newer C++11 "enum class" so that 
/// The enumeration constants are in the delivery_mode namespace. 
struct delivery_mode { 
    /// Delivery modes 
    enum modes { 
     /// No set policy. The application must settle messages 
     /// itself according to its own policy. 
     NONE = 0, 
     /// Outgoing messages are settled immediately by the link. 
     /// There are no duplicates. 
     AT_MOST_ONCE, 
     /// The receiver settles the delivery first with an 
     /// accept/reject/release disposition. The sender waits to 
     /// settle until after the disposition notification is 
     /// received. 
     AT_LEAST_ONCE 
    }; 

    /// @cond INTERNAL 

    delivery_mode() : modes_(NONE) {} 
    delivery_mode(modes m) : modes_(m) {} 
    operator modes() { return modes_; } 

    /// @endcond 

    private: 
    modes modes_; 
}; 

}

これは、 GCCバージョンの問題です.GCCのいくつかのバージョンは、この状況をエラーとして扱います。これらのバージョンの1つを使用している必要があります。具体的にタイプproton::delivery_modeを参照することによってあいまいさがあります。また、私が修正した相互運用性テストの構築にも問題がありました。私はまだ私が望むPythonのバインディングを構築することはできませんが、以下の変更でProton自身がビルドします。 Pythonバインディングの問題を見つけたら、この回答を更新します。
