                          INSTALLING Qt/Mac Version 4.4.0

Note for the binary package: If you have the binary package, simply double-click on the Qt.mpkg
and follow the instructions to install Qt. You can later run the \c{uninstal-qt.py}
script to uninstall the binary package. The script is located in /Developer/Tools and
must be run as root.

What follows is how to install Qt/Mac from the source package.

1.  If you have the commercial edition of Qt, install your license
    file as $HOME/.qt-license.

    For the open source version you do not need a license file.

2.  Unpack the archive if you have not done so already:

        cd /tmp
        gunzip qt-mac-opensource-src-4.4.0.tar.gz        # uncompress the archive
        tar xvf qt-mac-opensource-src-4.4.0.tar          # unpack it

    This creates the directory /tmp/qt-mac-opensource-src-4.4.0 containing the files
    from the archive.

3.  Building

    To configure the Qt library for your machine type, run the
    ./configure script in the package directory.

    By default, Qt is configured for installation in the
    /usr/local/Trolltech/Qt-4.4.0 directory, but this can be
    changed by using the -prefix option. Alternatively, the
    -prefix-install option can be used to specify a "local"
    installation within the source directory.

        cd /tmp/qt-mac-opensource-src-4.4.0
        ./configure

    Type "./configure -help" to get a list of all available options.

    Note that you will need to specify -universal if you want to
    build universal binaries, and also supply a path to the -sdk
    option if your development machine has a PowerPC CPU. By default,
    Qt is built as a framework, but you can built it as a set of
    dynamic libraries (dylibs) by specifying the -no-framework option.

    To create the library and compile all the demos, examples, tools,
    and tutorials, type:

        make

    If you did not configure Qt using the -prefix-install option,
    you need to install the library, demos, examples, tools, and
    tutorials in the appropriate place. To do this, type:

        sudo make install

    and enter your password, this requires that you have administrator access
    to your machine.

    If you need to reconfigure and rebuild Qt from the same location,
    ensure that all traces of the previous configuration are removed
    by entering the build directory and typing

        make confclean

    before running the configure script again.

    NOTE: If you encounter problems with header files having a size of zero and 
    no permissions, remove these files and try building again. This is typically 
    encountered when building with multiple jobs, so try running make -j1 instead.
    This is a known issue, and should be fixed in an upcoming release.

4.  Environment variables

    In order to use Qt, some environment variables needs to be
    extended.

        PATH               - to locate qmake, moc and other Qt tools

    This is done like this:

    In .profile (if your shell is bash), add the following lines:

        PATH=/usr/local/Trolltech/Qt-4.4.0/bin:$PATH
        export PATH

    In .login (in case your shell is csh or tcsh), add the following line:

        setenv PATH /usr/local/Trolltech/Qt-4.4.0/bin:$PATH

    If you use a different shell, please modify your environment
    variables accordingly.

5.  That's all. Qt is now installed.

    If you are new to Qt, we suggest that you take a look at the demos and
    examples to see Qt in action. Run the Qt Examples and Demos either by
    typing 'open /usr/local/Trolltech/Qt-4.4.0/bin/qtdemo.app' on the
    command line or by double-clicking on the 'qtdemo' icon in the Finder.
