在FC6下
安装QT4.2.3 gmake时 出现下面的问题
../../include/QtCore/../../src/corelib/tools/qmap.h:376: 警告：lowering visibility of ‘QDataStream& operator>>(QDataStream&, QMap<aKey, aT>&) [with aKey = aKey, aT = aT, Key = const QGraphicsItem*, T = QMap<int, QVariant>]’ to match its type
../../include/QtCore/../../src/corelib/tools/qmap.h: In instantiation of ‘QMap<int, QVariant>’:
graphicsview/qgraphicsitem.cpp:2289: instantiated from here
../../include/QtCore/../../src/corelib/tools/qmap.h:376: 警告：lowering visibility of ‘QDataStream& operator>>(QDataStream&, QMap<aKey, aT>&) [with aKey = aKey, aT = aT, Key = int, T = QVariant]’ to match its type
然后就一直循环警告，安装不下去了，望知者相告，谢谢
