Undefined reference, trying to write a TCP/IP application

[Dane]

Hello out there.

To learn some small things about TCP/IP, I'm trying to write my own small "chat".

It seems that there are no errors in my code, but the IDE still says: "undefined reference to '_imp___ZN10QTcpSocketC1EP7QObject'.

So I might have forgott to link some libraries.

Could you tell me which those are?

Regards,

Dane

Well,

QT += network

in your .pro file is enough. You should post some more details.

Hi,

I think it's still not working correctly.

My .pro file looks like this:

@#-------------------------------------------------

Project created by QtCreator 2010-08-02T14:56:46

#-------------------------------------------------

QT += core
+= network

QT -= gui

TARGET = SERVER_CLIENT
CONFIG += console
CONFIG -= app_bundle

TEMPLATE = app

SOURCES += main.cpp
client.cpp
server.cpp
packetwriter.cpp
packetreader.cpp

HEADERS +=
client.h
server.h
packetwriter.h
packetreader.h
@

The errors do still exist.

Regards,

Dane

Try replacing lines 7 and 8 are not correct qmake syntax. Try @QT += core network@ instead.
