我正在使用 QT-Creator 作为 macOS 10.8 上的 IDE 使用 QT 5.3 编写 C++ 应用程序。当我尝试加载 QMYSQL 插件时出现问题
db = QSqlDatabase::addDatabase("QMYSQL");
它导致
QSqlDatabase: QMYSQL driver not loaded
QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QODBC QODBC3 QPSQL QPSQL7
所以我试过了
loader.setFileName("/Users/kilian/Qt/5.3/clang_64/plugins/sqldrivers/libqsqlmysql_debug.dylib");
qDebug() << loader.load();
qDebug() << loader.errorString();
获得更好的输出
"Die Bibliothek /Users/foob/Qt/5.3/clang_64/plugins/sqldrivers/libqsqlmysql_debug.dylib kann nicht geladen werden:

所以我尝试了 otool
otool -L build-$appname-Desktop-Debug/$appname.app/Contents/MacOS/$appname
