OpenJDK9源码编译

完全参考http://www.jianshu.com/p/26bd050610a4这篇文章

1. 本机环境

• 系统版本：macOS Sierra (10.12)

• Boot JDK:

  • java -version

    ⋊> ~/study java -version                                                                                                                                                                          21:41:25
    java version "1.8.0_45"
    Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
    Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)

• XCode:

• xcodebuild -version

  ⋊> ~/study xcodebuild -version                                                                                                                                                                    22:00:15
  Xcode 8.0
  Build version 8A218a

  2. 安装必要软件

brew install ccache
brew install freetype

3. 下载源码

$ hg clone http://hg.openjdk.java.net/jdk9/jdk9 YourOpenJDK
$cd YourOpenJDK
$ bash ./get_source.sh

如果出现如下错误则重试

abort: stream ended unexpectedly (got 638305 bytes, expected 689947)

4. 编译

bash ./configure --with-freetype=/usr/local/opt/freetype --disable-zip-debug-info --disable-warnings-as-errors --with-debug-level=slowdebug 2>&1 | tee configure_mac_x64.log
