You may need to be root, depending on the permissions of the directories where you choose to install Qt.
    cd /usr/local
    gunzip qt-x11-version.tar.gz    # uncompress the archive
    tar xf qt-x11-version.tar       # unpack it
 
This creates the directory /usr/local/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 installed in /usr/local/qt.
This is done like this:
In .profile (if your shell is bash, ksh, zsh or sh), add the following lines:
    QTDIR=/usr/local/qt
    PATH=$QTDIR/bin:$PATH
    MANPATH=$QTDIR/man:$MANPATH
    LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
    export QTDIR PATH MANPATH LD_LIBRARY_PATH
 
In .login (in case your shell is csh or tcsh), add the following lines:
    setenv QTDIR /usr/local/qt
    setenv PATH $QTDIR/bin:$PATH
    setenv MANPATH $QTDIR/man:$MANPATH
    setenv LD_LIBRARY_PATH $QTDIR/lib:$LD_LIBRARY_PATH
 
After you have done this, you will need to login again, or re-source the profile before continuing, so that at least $QTDIR is set. The installation will give an error message and not proceed otherwise.
On AIX set LIBPATH and on HP-UX set SHLIB_PATH instead of LD_LIBRARY_PATH.
Note that the SGI MIPSpro o32 and Sun WorkShop 5.0 targets are no longer supported as of Qt 3.3.
Type:
    ./configure
 
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. Read PLATFORMS for a list of supported platforms.
To create the library and compile all examples and the tutorial:
    make
 
If you have problems, see
http://www.trolltech.com/platforms/.
If you have problems running the example programs, e.g. messages like
    can't load library 'libqt.so.2'
 
you probably need to put a reference to the qt library in a
configuration file and run /sbin/ldconfig as root on your system.
And don't forget to set LD_LIBRARY_PATH as explained in 2) above.
You're done. Qt is now installed.
