编译环境
- 操作系统： macOS Big Sur 11.4 20F71 x86_64
- CPU架构： x86
- BootStrap: zulu17.28.13-ca-jdk17.0.0-macosx_x64
编译版本： https://github.com/openjdk/jdk
下载jdk源码
git clone https://git.openjdk.java.net/jdk/
根据发布版本记录切换到 jdk17-ga版本
git checkout jdk-17-ga
运行配置
构建之前彻底清空上一次编译结果
make dist-clean
配置 BootStrap JDK。编译jdk17需要jdk17，下载已经编译好的jdk作为BootStrap JDK
同一个终端下配置JAVA_HOME
export JAVA_HOME=${jdk17 home}
最后执行bash configure， 处理WARN等日志
成功结果
