<h2 id="boot-jdk-requirements">Boot JDK Requirements</h2>
|
||||
<p>Paradoxically, building OpenJDK requires a pre-existing JDK. This is called the "boot JDK". The boot JDK does not have to be OpenJDK, though. If you are porting OpenJDK to a new platform, chances are that there already exists another JDK for that platform that is usable as boot JDK.</p>
|
||||
<p>The rule of thumb is that the boot JDK for building JDK major version <em>N</em> should be an JDK of major version <em>N-1</em>, so for building JDK 9 a JDK 8 would be suitable as boot JDK. However, OpenJDK should be able to "build itself", so an up-to-date build of the current OpenJDK source is an acceptable alternative. If you are following the <em>N-1</em> rule, make sure you got the latest update version, since JDK 8 GA might not be able to build JDK 9 on all platforms.</p>

<h2 id="external-library-requirements">External Library Requirements</h2>
|
||||
<p>Different platforms require different external libraries. In general, libraries are not optional - that is, they are either required or not used.</p>
|
||||
<p>If a required library is not detected by <code>configure</code>, you need to provide the path to it. There are two forms of the <code>configure</code> arguments to point to an external library: <code>--with-<LIB>=<path></code> or <code>--with-<LIB>-include=<path to include> --with-<LIB>-lib=<path to lib></code>. The first variant is more concise, but require the include files an library files to reside in a default hierarchy under this directory. In most cases, it works fine.</p>
