undefined refrence to QTcpServer::QTcpServer(QObject *)

while creating a object of QTcpServer in my constructor using new operator giving me this pbm.
It also leads to pbm in listen() saying undefined refrence to QHostAddress()...
I have included network module.
I successfully compiled the code of fortune server example. I tried to match both code but i donot find any difference.
Any suggestion to sort out this issue


quick nitin

Add "QT += network" to your .pro file.
