    Question Qt websocket program not compiling

    I have been working with QT and Ubuntu(14.04) for the last 2 months. I am using QT Creator 3.0.1 which is based on Qt 5.2.1.Currently I am developing a websocket program. When I compile a sample program I get the following error
    /usr/bin/ld: cannot find -lQt5WebSockets

    I have installed the following libraries:
    libqt5webkit5
    libqt5webkit5-dev
    libqt5webkit5:i386
    Please guide me as to how to fix this problem. Thanks and regards

    Do you have libQt5WebSockets.so in your library path?
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    Please ask Qt related questions on the forum and not using private messages or visitor messages.

    I have installed the following libraries:
    libqt5webkit5
    libqt5webkit5-dev
    libqt5webkit5:i386
    If you look at the names you will see that there is a certain difference.
    The library you look for ends in "sockets" the packages you have end in "kit".

    Based on that we could derive that the package you are looking for is
    libqt5websockets5-dev

    A quick search using the package manager confirms that.

    Cheers,

    I installed QT 5.3. Later I formed a symbolic link to the library. I also had to update the LD_LIBRARY_PATH to reflect the location of library. Thanks everything works now.
