MacOS 编译OpenJDK13

不念不忘少年蓝@ 2023-02-23 12:10 25阅读 0赞

官方说明 :

1.  Get the complete source code:  
    `hg clone http://hg.openjdk.java.net/jdk/jdk`
2.  Run configure:  
    `bash configure`
    
    If `configure` fails due to missing dependencies (to either the toolchain, build tools, external libraries or the boot JDK), most of the time it prints a suggestion on how to resolve the situation on your platform. Follow the instructions, and try running `bash configure` again.
3.  Run make:  
    `make images`
4.  Verify your newly built JDK:  
    `./build/*/images/jdk/bin/java -version`
5.  Run basic tests:  
    `make run-test-tier1`
6.

如何构建,可以查看里面的文档说明: doc/building.html

============  以下为操作实例 ==============================================

# 1. 准备安装环境: #

**1.首先需要准备一个Xcode**

我用的是Xcode9.4.1 版本 .  \[如果用其他高版本尚未测试.我编译OpenJDK10的时候是报错的.\]

官方下载地址:   [https://developer.apple.com/download/more/][https_developer.apple.com_download_more]

**2.JDK版本要求 12 或者13**

**3. brew 这个命令我就不说了, 去查一下,怎么安装.**

> **brew install freetype ccache**
> 
> **brew install mercurial**

在命令行输入 hg 命令有如下输出:

# 2.拉取源码包: #

> **git clone  git@github.com:openjdk/jdk13u.git**

注: 这个超级难下载,易炸毛.   不过比 hg 下载容易多了...

下载完的目录:

# 3.配置参数 #

接下来配置编译参数，以下是相关选项说明

*  `--with-debug-level=slowdebug` 启用slowdebug级别调试
 *  `--enable-dtrace` 启用dtrace
 *  `--with-jvm-variants=server` 编译server类型JVM
 *  `--with-target-bits=64` 指定JVM为64位
 *  `--enable-ccache` 启用ccache，加快编译
 *  `--with-num-cores=8` 编译使用CPU核心数
 *  `--with-memory-size=8000` 编译使用内存
 *  `--disable-warnings-as-errors` 忽略警告  , mac 使用 xcode 编译, 官方要求加上这个参数.
 *  **--with-freetype  设置freetype的路径, 这个路径必须为你机器上的路径,记得修改 !!!! **

> **$ bash configure --with-debug-level=slowdebug --enable-dtrace --with-jvm-variants=server --with-target-bits=64 --enable-ccache --with-num-cores=4 --with-memory-size=8000 --disable-warnings-as-errors**

编译完输出:

    /workspace/openjdk-13/build/macosx-x86_64-server-slowdebug
