I stumbled upon this warning in a compile log: [ 30%] [..]/work/kdelibs-4.5.2/kdeui/itemviews/kselectionproxymodel.cpp:2441:5: warning: "Qt_VERSION" is not defined The involved code is this: if (!sourceModel() || index.column() > 0 #if Qt_VERSION > 0x040700 || d->m_rootIndexList.isEmpty() #endif ) return 0; If I'm not all wrong "Qt_VERSION" must be "QT_VERSION", right?
Indeed it is, but please report it upstream directly, no need for us to patch it
