    Mistake what I have? please

    Hi, I have some errors in the implementation of my program, but which are not, here I leave the errors:
    1) C:\ejemplos_qt\teratermobile\cliente.cpp:-1: error: undefined reference to `QTcpSocket::QTcpSocket(QObject*)'
    \QtSDK\Symbian\SDKs\Symbian1Qt473\EPOC32\BUILD\ejemplos_qt\teratermobile\TERATERMOBILE_EXE\GCCE\UREL\cliente.o:-1: In function `cliente::cliente()':

    2) C:\ejemplos_qt\teratermobile\cliente.cpp:-1: error: undefined reference to `QTcpSocket::QTcpSocket(QObject*)'
    \QtSDK\Symbian\SDKs\Symbian1Qt473\EPOC32\BUILD\ejemplos_qt\teratermobile\TERATERMOBILE_EXE\GCCE\UREL\cliente.o:-1: In function `cliente::recv()':

    3) C:\ejemplos_qt\teratermobile\cliente.cpp:-1: error: undefined reference to `cliente:arseMessage(QString)'

    4) C:\ejemplos_qt\teratermobile\cliente.cpp:-1: error: undefined reference to `QAbstractSocket::abort()'

    5) C:\ejemplos_qt\teratermobile\cliente.cpp:-1: error: undefined reference to `QAbstractSocket::connectToHost(QString const&, unsigned short, QFlags<QIODevice::OpenModeFlag>)'

    6) C:\ejemplos_qt\teratermobile\cliente.cpp:-1: error: undefined reference to `QAbstractSocket::isValid() const'

    and my code cliente.cpp is this:


    #include "cliente.h"
    #include <QtNetwork/QTcpSocket>

    cliente::cliente()
    {
    //READ: Instanciar Socket y conectar las señales, la

    ==>> socket = new QTcpSocket(this);

    connect( socket, SIGNAL(connected()), this, SLOT(conectado()));
    connect( socket, SIGNAL(readyRead()), this, SLOT(recv()));
    connect( socket, SIGNAL(disconnected()), this, SLOT(disconnect()));
    connect( socket, SIGNAL(error(QAbstractSocket::SocketError)),
    this, SLOT(displayError(QAbstractSocket::SocketError)));

    ¨¨¨¨¨¨¨¨

    and error mark me where is this sign ==>>

    an my code cliente.h is this.

    #ifndef CLIENTE_H
    #define CLIENTE_H



    #include <QObject>

    #include <QtNetwork/QTcpSocket>

    class cliente: public QObject
    {
    Q_OBJECT

    public:

    cliente();

    //READ: El socket que mantiene la comunicacion y un array de bytes para enviar
    // y leer mensajes
    QTcpSocket *socket;
    bool estaConectado;

    Re: Mistake what I have? please

    could it be that you are defined a function ParseMessage in cliente.h, and are trying to use it, and you forgot to actually implement it in the cliente.cpp file.
