Description
When compiled with clang, the module QmlPluginDump produces the following error:
qtdeclarative/tools/qmlplugindump/main.cpp:118:44: error: use of overloaded operator '==' is ambiguous (with operand types 'const QString' and 'QHashedString') || versionInfo.pluginImportUri == ty.module() ~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~ /home/twdragon/src/qt5/build/qtbase/include/QtCore/../../../../qtbase/src/corelib/text/qstring.h:806:31: note: candidate function friend Q_CORE_EXPORT bool operator==(const QString &s1, const QString &s2) noexcept; ^ ../../include/QtQml/5.15.2/QtQml/private/../../../../../../../qtdeclarative/src/qml/qml/ftw/qhashedstring_p.h:212:21: note: candidate function (with reversed parameter order) bool QHashedString::operator==(const QHashedString &string) const ^ ../../include/QtQml/5.15.2/QtQml/private/../../../../../../../qtdeclarative/src/qml/qml/ftw/qhashedstring_p.h:218:21: note: candidate function (with reversed parameter order)
The workaround is to select the inherited type explicitly in file qtdeclarative/tools/qmlplugindump/main.cpp:
static bool matchingImportUri(const QQmlType &ty, const QmlVersionInfo& versionInfo) { if (versionInfo.strict) { return (versionInfo.pluginImportUri == static_cast<QString>(ty.module()) && (ty.majorVersion() == versionInfo.majorVersion || ty.majorVersion() == -1)) || ty.module().isEmpty(); } return ty.module().isEmpty() || versionInfo.pluginImportUri == static_cast<QString>(ty.module()) || ty.module().startsWith(versionInfo.pluginImportUri + QLatin1Char('.')); }
instead of:
static bool matchingImportUri(const QQmlType &ty, const QmlVersionInfo& versionInfo) { if (versionInfo.strict) { return (versionInfo.pluginImportUri == ty.module() && (ty.majorVersion() == versionInfo.majorVersion || ty.majorVersion() == -1)) || ty.module().isEmpty(); } return ty.module().isEmpty() versionInfo.pluginImportUri == ty.module() ty.module().startsWith(versionInfo.pluginImportUri + QLatin1Char('.')); }
