Installing Qt/Mac

You may need to be logged in as root, depending on the permissions of the directories where you choose to install Qt.

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

        cd /Developer
        gnutar xzf qt-mac-version.tar.gz

    This creates the directory /Developer/qt-version containing the files from the main archive.

    Rename qt-version to qt (or make a symlink):

        mv qt-version qt

    The rest of this file assumes that Qt is unpacked in /Developer/qt.

  2. Set some environment variables in the file .profile (or .login, depending on your shell) in your home directory. Create the file if it is not there already.

    This is done like this:

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


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

        setenv QTDIR /Developer/qt
        setenv PATH $QTDIR/bin:$PATH
        setenv MANPATH $QTDIR/man:$MANPATH

    After you have done this, you will need to login again, or re-source the profile before continuing.

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

  4. Compile the Qt library, and build the example programs, the tutorial and the tools (e.g. Qt Designer) as follows.


        cd $QTDIR

    This will configure the Qt library for your machine. Note that GIF support is turned off by default. Run ./configure -help to get a list of configuration options.

    To create the library and compile all examples and the tutorial:

    If you have problems, see http://www.trolltech.com/platforms/.

  5. Once you have built Qt, it is ready to use. If Qt has not been configured with the -static option, then in order to be able to launch Qt applications from the Finder you must place the relevant libraries in a directory where they can be found. We recommend making these symbolic links (if you have configured Qt with -thread please change the libqt below with libqt-mt):

        ln -sf $QTDIR/lib/libqt.3.dylib /usr/lib
        ln -sf $QTDIR/lib/libqui.1.dylib /usr/lib

    You may need to have 'administrator' access to do this, (in which case, precede each command with sudo', e.g. sudo ln -s ...). If you use sudo you'll be prompted for the administrator password.

    If you do not have administrator access, or you would prefer to do a user install (rather than system install) of the libraries you can do (if you have configured Qt with -thread please change the libqt below with libqt-mt):

        ln -sf $QTDIR/lib/libqt.3.dylib $HOME/lib
        ln -sf $QTDIR/lib/libqui.1.dylib $HOME/lib

That's all! Qt is now installed. Qt's documentation can be read with Qt Assistant or by any web browser; the contents page is $QTDIR/doc/html/index.html.
