  • nealthwin Please start new thread with you question.
    I suggest you to use the latest (5.2.1) version of Qt.
    You can download it "here":http://qt-project.org/downloads

    EDIT: I have split this out into a new thread --JKSH

    Hi nealthwin,

    [quote]-I/usr/share/qt4/mkspecs/linux-g++[/quote]Your system is trying to mix Qt 3 and Qt 4. You cannot mix versions.

    How did you install Qt? What is the title of the book?
