<h1 class="section">Sharing Defaults</h1> <p>If you want to set default values for <code>configure</code> scripts to share, you can create a site shell script called <code>config.site</code> that gives default values for variables like <code>CC</code>, <code>cache_file</code>, and <code>prefix</code>. <code>configure</code> looks for <samp>PREFIX/share/config.site</samp> if it exists, then <samp>PREFIX/etc/config.site</samp> if it exists. Or, you can set the <code>CONFIG_SITE</code> environment variable to the location of the site script. A warning: the Bash <code>configure</code> looks for a site script, but not all <code>configure</code> scripts do. </p><div class="_attribution">
