<h4>Building with ccache</h4>
<p>A simple way to radically speed up compilation of native code
(typically hotspot and native libraries in JDK) is to install
ccache. This will cache and reuse prior compilation results, if the
source code is unchanged. However, ccache versions prior to 3.1.4
does not work correctly with the precompiled headers used in
OpenJDK. So if your platform supports ccache at 3.1.4 or later, we
highly recommend installing it. This is currently only supported on
linux.</p>
<p>The OpenJDK build supports building with ccache
when using gcc or clang. Using ccache can
radically speed up compilation of native code if
you often rebuild the same sources. Your milage
may vary however so we recommend evaluating it for
yourself. To enable it, make sure it's on the path
and configure with <code>--enable-ccache</code>.</p>
