<li><p>Configure and build the LLVM libraries and tools. There are two ways to
do this: either with <i>objdir</i> == <i>srcdir</i> or not. It is recommended
that <i>srcdir</i> not be the same as <i>objdir</i>:</p>

<li>With <i>objdir</i> != <i>srcdir</i>:<pre>

<p>This will build all of the LLVM tools and libraries. The <tt>--prefix</tt>
option defaults to /usr/local (per configure standards) but unless you are a
system administrator, you probably won't be able to install LLVM there because
of permissions. Specify a path into which LLVM can be installed (e.g.
<tt>--prefix=/home/user/llvm</tt>).</p>
