Kubuntu 7.10; Qt4.3.4
./configure well done
but for attemt make i get: 

cd src/ && make -f Makefile

It's quite strange, because application.cpp includes the QSessionManager header. Perhaps your version of Qt is configured with session management disabled for some reason. If that's the case, the following modification would fix this: 

void Application::commitData( QSessionManager& manager )
{
#ifndef QT_NO_SESSIONMANAGER
    if ( manager.allowsInteraction() ) {
        if ( viewManager && !viewManager->queryCloseViews() )
            manager.cancel();
    }
#endif
}
