A binary package is available and the <a href="qtinstaller.html">Qt Installation Program</a> page describes the installation in more detail.</p> <a name="step-1-installing-the-license-file-commercial-editions-only"></a> <h2>Step 1: Installing the License File (commercial editions only)</h2> <p>If you have the commercial edition of Qt, install your license file as <tt>$HOME/.qt-license</tt>.</p> <p>For the open source version you do not need a license file.</p> <a name="step-2-unpacking-the-archive"></a> <h2>Step 2: Unpacking the Archive</h2> <p>Unpack the archive if you have not done so already. For example, if you have the <tt>qt-everywhere-opensource-src-5.1.1.tar.gz</tt> package, type the following commands at a command line prompt:</p> <pre class="cpp">cd <span class="operator">/</span>tmp gunzip qt<span class="operator">-</span>everywhere<span class="operator">-</span>opensource<span class="operator">-</span>src<span class="operator">-</span><span class="number">5.1.1.tar.gz</span> <span class="preprocessor"># uncompress the archive</span> tar xvf qt<span class="operator">-</span>everywhere<span class="operator">-</span>opensource<span class="operator">-</span>src<span class="operator">-</span><span class="number">5.1.1.tar</span> <span class="preprocessor"># unpack it</span></pre> <p>This creates the directory <tt>/tmp/qt-everywhere-opensource-src-5.1.1</tt> containing the files from the archive. We only support the GNU version of the tar archiving utility. Note that on some systems it is called gtar.</p> <a name="step-3-building-the-library"></a> <h2>Step 3: Building the Library</h2> <p>To configure the Qt library for your machine type, run the <tt>./configure</tt> script in the package directory.</p> <p>By default, Qt is configured for installation in the <tt>/usr/local/Qt-5.1.1</tt> directory, but this can be changed by using the <tt>-prefix</tt> option.</p> <pre class="cpp">cd <span class="operator">/</span>tmp<span class="operator">/</span>qt<span class="operator">-</span>everywhere<span class="operator">-</span>opensource<span class="operator">-</span>src<span class="operator">-</span><span class="number">5.1.1</span> <span class="operator">.</span><span class="operator">/</span>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 examples, tools, and tutorials, type:</p> <pre class="cpp">make</pre> <p>If <tt>-prefix</tt> is outside the build directory, you need to install the library, examples, tools, and tutorials in the appropriate place. To do this (as root if necessary), type:</p> <pre class="cpp">make install</pre> <p>Note that on some systems the make utility is named differently, e.g. gmake. The configure script tells you which make utility to use.</p> <p><b>Note:</b> If you later 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 <tt>make confclean</tt> before running <tt>configure</tt> again.</p> <a name="step-4-set-the-environment-variables"></a> <h2>Step 4: Set the Environment Variables</h2> <p>In order to use Qt, some environment variables needs to be extended.</p> <pre class="cpp">PATH <span class="operator">-</span> to locate qmake<span class="operator">,</span> moc <span class="keyword">and</span> other <span class="type">Qt</span> tools</pre> <p>This is done like this:</p> <p>In <tt>.profile</tt> (if your shell is bash, ksh, zsh or sh), add the following lines:</p> <pre class="cpp">PATH<span class="operator">=</span><span class="operator">/</span>usr<span class="operator">/</span>local<span class="operator">/</span><span class="type">Qt</span><span class="operator">-</span><span class="number">5.1.1</span><span class="operator">/</span>bin:$PATH <span class="keyword">export</span> PATH</pre> <p>In <tt>.login</tt> (in case your shell is csh or tcsh), add the following line:</p> <pre class="cpp">setenv PATH <span class="operator">/</span>usr<span class="operator">/</span>local<span class="operator">/</span><span class="type">Qt</span><span class="operator">-</span><span class="number">5.1.1</span><span class="operator">/</span>bin:$PATH</pre> <p>If you use a different shell, please modify your environment variables accordingly.</p> <p>For compilers that do not support rpath you must also extended the <tt>LD_LIBRARY_PATH</tt> environment variable to include <tt>/usr/local/Qt-5.1.1/lib</tt>. On Linux with GCC this step is not needed.</p> <p><b>That's all. Qt is now installed.</b></p> <a name="qt-demos-and-examples"></a> <h2>Qt Demos and Examples</h2> <p>If you are new to Qt, we suggest that you take a look at the examples to see Qt in action. Run the Qt Examples either by typing <tt>qtdemo</tt> on the command line or through the desktop's Main menu.</p> <p>You might also want to try the following links:</p> <ul> <li>How to Learn Qt</li> <li><a href="qtexamplesandtutorials.html">Qt Examples and Tutorials</a></li> <li><a href="deployment.html">Deploying Qt Applications</a></li> </ul> <p>We hope you will enjoy using Qt.
