<div class="descr"> <a name="details"></a>
<p>This page gives a brief description of the different options available when building Qt using the <tt>configure</tt> script or <tt>configure.exe</tt> binary. To build Qt using the default options, just call configure from the command line as shown below.</p>
<p>When building on Linux, Mac OS X and Unix platforms:</p>
<p><tt>./configure</tt></p>
<p>On Windows, run the corresponding executable:</p>
<p><tt>.\configure.exe</tt></p>
<p>If you would like to customize your build, please use the options listed in the following tables. To see the full list of options, invoke the configure tool with the <tt>-help</tt> command line option.</p>
