<li>If you have the commercial edition of Qt, install your license file as <tt>$HOME/.qt-license</tt>.<p>For the open source version you do not need a license file.</p>

</li>

<li>Unpack the archive if you have not done so already:<pre>  cd /tmp

gunzip qt-x11-opensource-desktop-4.0.0.tar.gz # uncompress the archive

tar xvf qt-x11-opensource-desktop-4.0.0.tar # unpack it</pre>

<p>This creates the directory <tt>/tmp/qt-x11-opensource-desktop-4.0.0</tt> containing the files from the archive.</p>

</li>

<li>Building<p>To configure the Qt library for your machine type:</p>

<pre>  cd /tmp/qt-x11-opensource-desktop-4.0.0

./configure</pre>

<p>Type <tt>./configure -help</tt> to get a list of all available options.</p>

<p>To create the library and compile all the demos, examples, tools, and tutorials, type:</p>

<p>To install the library, demos, examples, tools, and tutorials, type:</p>

<pre>  su -c "make install"</pre>

<p>and enter the root password. Qt is by default installed into <tt>/usr/local/Trolltech/Qt-4.0.0</tt> but this can be changed by using the <tt>-prefix</tt> parameter.</p>

</li>

<li>Environment variables<p>In order to use Qt, some environment variables need to be extended.</p>

<pre>  PATH - to locate qmake, moc and other Qt tools</pre>

<p>In <tt>.profile</tt> (if your shell is bash), add the following lines:</p>

<pre>  PATH=/usr/local/Trolltech/Qt-4.0.0/bin:$PATH

export PATH</pre>

<p>In <tt>.login</tt> (in case your shell is csh or tcsh), add the following line:</p>

<pre>  setenv PATH /usr/local/Trolltech/Qt-4.0.0/bin:$PATH</pre>

<p>If you use a different shell, please modify your environment variables accordingly.</p>

</li>

<li>That's all. Qt is now installed.<p>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 <tt>qtdemo</tt> on the command line or through the desktop's Start menu.</p>
