$$$install-mac.html-description --> <div class="descr"> <a name="details"></a> <p>Qt for Mac OS X has some requirements that are given in more detail in the <a href="requirements-mac.html">Qt for Mac OS X Requirements</a> document.</p> <p>The following instructions describe how to install Qt from the source package.</p> <p>For the binary package, simply double-click on the Qt.mpkg and follow the instructions to install Qt. You can later run the <tt>uninstall-qt.py</tt> script to uninstall the binary package. The script is located in /Developer/Tools and must be run as root.</p> <p><b>Note:</b> Do not run the iPhone simulator while installing Qt. The <a href="http://openradar.appspot.com/7214991">iPhone simulator conflicts with the package installer</a>.</p> <a name="step-1-install-the-license-file-commercial-editions-only"></a> <h2>Step 1: Install 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> <p>Unpack the archive if you have not done so already. For example, if you have the <tt>qt-everywhere-opensource-src-4.8.5.tar.gz</tt> package, type the following commands at a command line prompt:</p> <pre class="cpp"> cd /tmp gunzip qt-everywhere-opensource-src-4.8.5.tar.gz # uncompress the archive tar xvf qt-everywhere-opensource-src-4.8.5.tar # unpack it</pre> <p>This creates the directory <tt>/tmp/qt-everywhere-opensource-src-4.8.5</tt> containing the files from the archive.</p> <a name="step-2-build-the-qt-library"></a> <h2>Step 2: Build the Qt 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/Trolltech/Qt-4.8.5</tt> directory, but this can be changed by using the <tt>-prefix</tt> option.</p> <pre class="cpp"> cd /tmp/qt-everywhere-opensource-src-4.8.5 ./configure</pre> <p>Type <tt>./configure -help</tt> to get a list of all available options.</p> <p>Note that you will need to specify <tt>-universal</tt> if you want to build universal binaries, and also supply a path to the <tt>-sdk</tt> 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 <tt>-no-framework</tt> option.</p> <p>Qt can also be configured to be built with debugging symbols. This process is described in detail in the <a href="debug.html">Debugging Techniques</a> document.</p> <p>To create the library and compile all the demos, 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, demos, examples, tools, and tutorials in the appropriate place. To do this, type:</p> <pre class="cpp"> sudo make -j1 install</pre> <p>This command requires that you have administrator access on your machine.</p> <p><b>Note:</b> There is a potential race condition when running make install with multiple jobs. It is best to only run one make job (-j1) for the install.</p> <p>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-3-set-the-environment-variables"></a> <h2>Step 3: Set the Environment variables</h2> <p>In order to use Qt, some environment variables need to be extended.</p> <pre class="cpp"> PATH - to locate qmake, moc and other Qt tools</pre> <p>This is done like this:</p> <p>In <tt>.profile</tt> (if your shell is bash), add the following lines:</p> <pre class="cpp"> PATH=/usr/local/Trolltech/Qt-4.8.5/bin:$PATH export 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 /usr/local/Trolltech/Qt-4.8.5/bin:$PATH</pre> <p>If you use a different shell, please modify your environment variables accordingly.</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 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> <p>You might also want to try the following links:</p> <ul> <li><a href="how-to-learn-qt.html">How to Learn Qt</a></li> <li><a href="tutorials.html">Tutorials</a></li> <li><a href="http://qt-project.org">Developer Network</a></li> <li><a href="deployment.html">Deploying Qt Applications</a></li> </ul> <p>We hope you will enjoy using Qt.
