    I have board I.MX6Q and try build Qt5.4 from source.

    I got http://download.qt-project.org/development_releases/qt/5.4/5.4.0-beta/single/qt-everywhere-opensource-src-5.4.0-beta.tar.xz

    When I compile I got errors:

    .obj/qsqldatabase.o:qsqldatabase.cpp:function QSqlDatabasePrivate::database(QString const&, bool): error: undefined reference to ‘QDebug::~QDebug()’

    .obj/qsqlfield.o:qsqlfield.cpp:function operator<<(QDebug, QSqlField const&): error: undefined reference to ‘QDebug::~QDebug()’

    .obj/qtestlog.o:qtestlog.cpp:function QTest::messageHandler(QtMsgType, QMessageLogContext const&, QString const&): error: undefined reference to ‘qFormatLogMessage(QtMsgType, QMessageLogContext const&, QString const&)’

    .obj/qnetworkaccessbackend.o:qnetworkaccessbackend.cpp:function QNetworkAccessBackend::createUploadByteDevice(): error: undefined reference to ‘QNonContiguousByteDeviceFactory::createShared(QSharedPointer<QRingBuffer>)’
