如何优雅的编译OpenJDK(Mac 版)

悠悠 2022-04-11 10:14 765阅读 0赞

### 前言 ###

最近拜读`《深入理解Java虚拟机》`一书。书中第一章要求，自己编译Java虚拟机。我尝试的编译了一下，发现随着`Mac和Code`版本的不断更新，要做到编译书中提及的`OpenJDK1.7`已经非常的困难。至此，将编译过程纪录于此，以慰后继来者。

PS: 编译的整个流程花费了2天多的时间，准备周日晚上编译完就睡的，结果编译到第二天白天还没完成。编译期间失败大概有100多次，最后还是将问题一一解决了。不要放弃，有可能解决了这个问题，下一步就是成功!  
另外，听说Mac当前版本编译`OpenJDK1.9`较为容易，大家未开始前可以转编译`OpenJDK1.9`过程会容易一下。

--------------------

### 环境准备 ###

*  Mac 10.14
 *  XCode 10.1
 *  Command\_Line\_Tools\_macOS\_10.14\_for\_Xcode\_10.1.dmg
 *  Cups 2.2.9
 *  Ant 1.7.1
 *  Bootstrap JDK 1.7.0\_75/1.8.0\_102

各文件下载地址:  
[OpenJDK源码][OpenJDK]  
[Mac阵营(XCode & Command\_Line\_Tools)][Mac_XCode _ Command_Line_Tools]  
[Cups][]  
[Cups Github][]  
[Ant][]  
[JDK][]

注: 1.Oracle JDK 1.6没有Mac版本的官方版，linux版本的我没装上。  
2. OpenJDK没使用hg这样的管理工具，直接下载的现成的包。我下载的版本为`openjdk-7u75-src-b13-18_dec_2014.zip`。

--------------------

### 环境变量设置 ###

> 之前没有用javac编译，直接随便创建一个文件导致的这个问题。困扰好久。javac编译即可。做法见上。

PS: 一共经历快20多个问题，才折磨结束。勇士们，还是编译`OpenJDK1.9`去吧。环境和类库的地址的变化导致了这样一系列的问题。后续就是如何调试OpenJDK和使用Hostpot虚拟机了。

### Tips ###

*  `javac`与`javap`

> javac 用来编译 ABC.java 文件，将之转换为ABC.class文件；javap是反编译工具，用来读取ABC.class文件内内容工具。两者都是`JDK的bin目录`自带的工具。  
> 参考: [反编译class文件并重新编译的方法][class]  
> [怎样加Java文件编译成class文件][Java_class]

*  Makefile missing separator. Stop.怎么解决

> 遇到这个问题，一般是Makefile文件被改错了。因为Makefile文件要求每个命令前是需要以`TAB`作为分隔符号。好好检查报错的Makefile文件。

### Others ###

一路下来，本地编译OpenJDK实属不易。有很多人通过虚拟机安装和Docker版本安装会轻松很多。

参考文章:  
[修改，编译，GDB调试openjdk8源码(docker环境下)][GDB_openjdk8_docker]

> 为什么要编译OpenJDK？  
> 之前突然想到这个问题。编译好处在于可以定制化调试参数，定制化查看源码研究。而别人编译好的JDK二进制文件是无法修改的。这就是编译的好处。当然，运维，还是直接安装，类如`rpm`、`yum install`、`apt-get`省事的多。
