Hi,

you must add qtnetwork module in your .pro file

@
QT += network

Hello and welcome,

"QTcpServer":http://qt-project.org/doc/qt-5.0/qtnetwork/qtcpsocket.html (and "QNetworkSession":http://qt-project.org/doc/qt-5.0/qtnetwork/qnetworksession.html) classes are held in a "QtNetwork":http://qt-project.org/doc/qt-5.0/qtnetwork/qtnetwork-module.html module. Did you add it to your project .pro file to link against it when compiling?
To "link against QtNetwork":http://qt-project.org/doc/qt-5.0/qtnetwork/qtnetwork-module.html#details, add this line:
@QT += network@
