誰かがjsonrpc-cppをコンパイルする手助けをしてくれることを願っています。 （http://jsonrpc-cpp.sourceforge.net/）C++：Sconsエラー： "あいまいなオーバーロード"
私はドキュメントごとにsconsを入力すると、私が手に：ここ

私は本当に誰かが正しい方向に私を向けることができると思っています。事前に
多くのおかげで、
編集：ここで私はライン208と213にやったことだ：
プロセス（ルート[（JSON ::バリュー:: ArrayIndex）i]と、RET） ; //行208
レスポンス[（Json :: Value :: ArrayIndex）j] = ret; //行213
ええ、私はそれを開発者に報告していますか？ –
コメントありがとうございました... – Eamorr
208行目と213行目で 'Json :: Value :: ArrayIndex'にキャストしようとするか、単にバグレポートを提出してください。 – slaphappy
