[Solved] 'undefined reference to `QTcpSocket::QTcpSocket(QObject*)'

endla.ravi

hi,

I am unable to to use QTcpSocket(same with the case of other QTNetwork modules like QUdpSocket..)

even if i give
@QTcpSocket tcp;@

and run the code,i am getting these compilation errors
@
/home/ravi/Messenger-build-desktop/../Messenger/messengerwindow.cpp:215: error: undefined reference to `QTcpSocket::QTcpSocket(QObject*)'

/home/ravi/Messenger-build-desktop/../Messenger/messengerwindow.cpp:215: error: undefined reference to `QTcpSocket::~QTcpSocket()'

/home/ravi/Messenger-build-desktop/../Messenger/messengerwindow.cpp:215: error: undefined reference to `QTcpSocket::QTcpSocket(QObject*)'

/home/ravi/Messenger-build-desktop/../Messenger/messengerwindow.cpp:215: error: undefined reference to `QTcpSocket::~QTcpSocket()'

error: collect2: ld returned 1 exit status
@

And by the way,i have included evrything i should

ie..

@
#include<QTNetwork/QTcpSocket>
@

and when i type tcp. I am able to see the snippet.There is no problem while including the class..but only problem while compilation.

How can i solve this problem

thanks in advance

This is a linker error and caused by QtNetwork lib not being linked to your program.

Did you add

@
QT += network
@

to your .pro file? This should make your linker error go away.

Have you updated your .pro file with:
@
QT += network
@?
