| 有効/無効設定 | このワーニングクラスのチェックはデフォルトで無効になっており、プロジェクトには非正規の C向けAST
が必要になります。有効にするにはプロジェクト設定ファイル (configuration file) に以下の WARNING_FILTER ルールと
RETAIN_UNNORMALIZED_C_AST 設定を追加してください。
RETAIN_UNNORMALIZED_C_AST = Yes WARNING_FILTER += allow class="Use of Array Type" If you prefer to enable this class for C++ code only, add language=c++ to your WARNING_FILTER rule: WARNING_FILTER += allow class="Use of Array Type" language=c++ |

設定ファイルの以下のパラメータがこのワーニングクラスのチェックに影響します。
