Cannot build application using Qt

[debugger]

Hi all,

I am a newbie. I developed an application that worked on Qt 4.8.0, and am trying to port it to Qt 5.1.1. But I cannot link the application. Compiling is done successfully and thus all .o files are created. Now with the linking, it shows undefined reference to <class> : <function>

I have given LIB path correctly.. But it shows linking error with all functions in QtWebKit and QtWebKitWidgets... Please help..

Have a look at "this":http://qt-project.org/doc/qt-5.0/qtdoc/portingguide.html and "that":http://qt-project.org/wiki/Transition_from_Qt_4.x_to_Qt5

Hi Rahul Das,

Thanks for your reply. I've gone throught the links provided. Especially "this":http://qt-project.org/wiki/Transition_from_Qt_4.x_to_Qt5

But when I added QT+=webkitwidgets and tried to do qmake,
I get the following error

Project ERROR: Unknown module(s) in QT: webkitwidgets

I saw in some forum to perform this:
sudo apt-get locate libqt5webkit5-dev

But was unable to locate the same...

Also I coudnt find fixqt4headers perl script
