<h1 id="背景"><a href="#背景" class="headerlink" title="背景"></a>背景</h1><p>出于对JVM的好奇，笔者最近在看《HotSpot 实战》，希望能够更加深入的了解下JVM内部的原理和实现。作者第一步就让我们尝试自己去编译Openjdk，看似简单，然而bug频出，笔者查了无数资料才得以编译成功，所以分享出来希望能够为想要编译openjdk的朋友提供点微小的帮助。</p>

</ul>
<h1 id="编译"><a href="#编译" class="headerlink" title="编译"></a>编译</h1><p>上面的几步问题都不大, 关键是编译过程遇到的问题，非常的坑。</p>
<blockquote>
<p>Error: JAVA_HOME is not defined correctly.<br>We cannot execute /NO_BOOTDIR/bin/java</p>
</blockquote>
<p>这个问题的原因是没有设置<strong>ALT_BOOTDIR</strong>，之前脚本确实设置过，但是为什么没生效笔者也没搞懂，希望懂的同志能够留个言。</p>
<blockquote>
<p>ERROR: Cannot find source for project jaxp.<br>ALLOW_DOWNLOADS=true</p>
</blockquote>
<p>这个问题的原因是openjdk中的一部分组件包括jaxws, jaxp的源码是在编译期才会去下载，所以要开启允许下载选项。</p>
<blockquote>
<p>ERROR: echo “<em>*</em> This OS is not supported:” ‘uname -a’; exit 1; </p>
</blockquote>
<p>关闭操作系统版本检查</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">export DISABLE_HOTSPOT_OS_VERSION_CHECK=OK</span><br></pre></td></tr></table></figure>
<blockquote>

</blockquote>
<p>这里我处理的方法有点笨，对照 <a href="http://hg.openjdk.java.net/hsx/hsx23/hotspot/rev/a6eef545f1a2#l4.1" target="_blank" rel="noopener">http://hg.openjdk.java.net/hsx/hsx23/hotspot/rev/a6eef545f1a2#l4.1</a> 进行修改，一共有六个文件，修改的时候注意有些代码行最后会有一个 <strong>‘\’</strong> 注意一起拷贝下来。</p>
<blockquote>
<p>编译jaxws和jaxp的时候发生错误</p>
</blockquote>
<p>openjdk这些组件的托管已经改变位置，所以下载的时候会发生错误。我的解决办法是下载这些源码，并且放到 <strong>path/openjdk/jdk7-drops/</strong> 目录下。然后设置</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">export ALT_DROPS_DIR = path/openjdk/jdk7-drops</span><br></pre></td></tr></table></figure>
<blockquote>

<p>找到这一行，两种修改方法：</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br></pre></td><td class="code"><pre><span class="line">1. return (methodOop)false;</span><br><span class="line">2. return NULL;</span><br></pre></td></tr></table></figure>

<p>需要修改openjdk/jdk/make/javax/sound/jsoundalsa目录下的Makefile文件，找到 LDFLAGS += -lasound 修改为 OTHER_LDLIBS += -lasound</p>
<h1 id="总结"><a href="#总结" class="headerlink" title="总结"></a>总结</h1><p>坑非常多，所以笔者给大家准备了我经过修改之后的openjdk，应该是会少很多的Bug，希望给读者带来帮助。<br><a href="https://github.com/wssgyyg/OpenjdkBugfree" target="_blank" rel="noopener">https://github.com/wssgyyg/OpenjdkBugfree</a></p>
