    Default QtMultimedia not included

    Hi everyone, I'm new here and I have a big problem.
    I'm using qt libraries on ubuntu 12.04 system and I have compiled the 4.8.4 version with:

    ./configure -opengl
    sudo make install

    at the end of make execution, the program says to me that the libraries will be installed inside /usr/local/Trolltech/Qt-4.8.4 directory.
    I made a simple hello world program with gui and it works very well, but when I use QAudioInput from QtMultimedia and I try to compile, the compiler gives to me: No such file or directory.
    Qt Code:
    1. #include <QAudioInput>
    2. #include <QAudioOutput>
    To copy to clipboard, switch view to plain text mode 
    However the folder QtMultimedia inside /usr/local/Trolltech/Qt-4.8.4/include exists. Anyone knows how it is possible that the library is correctly installed but the compiler doesn't see it??

    After that I tried to include the libraries path inside the .pro file:
    Qt Code:
    1. INCLUDEPATH += -I/usr/local/Trolltech/Qt-4.8.4/include
    To copy to clipboard, switch view to plain text mode 
    it still does not link the library QAudioInput.
    Please help me...

    Probably you've just forgotten QT += multimedia in you .pro file. You do not need to change or add additional include files at all.
