undefined reference Error in helloworld program !

[prady]

Hi,

I am again new to Qt world !

I have created a Helloworld Program in Qt 4.7.0 ( 32 bit windows ), using QtCreater 2.0.1.

#include <QtCore/QCoreApplication>
#include <QtGui/QLabel>
 
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
 
    QLabel label("Hello World!");
    label.show();
 
    return a.exec();
}

#include <QtCore/QCoreApplication>
#include <QtGui/QLabel>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    QLabel label("Hello World!");
    label.show();

    return a.exec();
}

To copy to clipboard, switch view to plain text mode 

when I build this code getting the following errors,

main.cpp:11: undefined reference to `_imp___ZN6QLabelD1Ev'
 
collect2: ld returned 1 exit status

main.cpp:11: undefined reference to `_imp___ZN6QLabelD1Ev'

collect2: ld returned 1 exit status

To copy to clipboard, switch view to plain text mode 

could anybody let me know, what I am doing wrong in this simple code ???

Thanks,
Pradeep.
