おはようございます、
私は現在、Qt プロジェクト (使用するソフトウェア: VS 2010) に取り組んでいます。QLogger.cpp で、関数 addDestination に C2511 エラーがありますが、すべての関数が正しく使用されているため、理由がわかりません。デバッグモードでは動作しないため、リリースモードでコーディングしています。
ここに完全なメッセージエラーがあります:
エラー 1 エラー C2511: 'bool QLogger::QLoggerManager::addDestination(const QString &,const QString &,QLogger::LogLevel)': オーバーロードされたメンバー関数が 'QLogger::QLoggerManager' C:\Users\gdeca_000\Desktop に見つかりません\qt-coding\QLogger\QLogger.cpp 104
ここで.hコード：
static QString levelToText(const LogLevel &level);
/**
* @brief This method creates a QLoogerWriter that stores the name of the file and the log
* level assigned to it. Here is added to the map the different modules assigned to each
* log file. The method returns <em>false</em> if a module is configured to be stored in
* more than one file.
*
* @param fileDest The file name and path to print logs.
* @param modules The modules that will be stored in the file.
* @param level The maximum level allowed.
* @return Returns true if any error have been done.
