# Mac10.15.7上编译OpenJDK8u ## 机器环境及依赖 操作系统：`macOs 10.15.7` BootJDK: `/Library/Java/JavaVirtualMachines/jdk1.8.0_221.jdk/Contents/Home` XCode：`Version 11.3.1 (11C505)` hg命令(mercurial): `brew install mercurial` freetype: `brew install freetype` **注意：笔者先前打算编译jdk8，一番折腾后各种报错，最后选择jdk8u的版本。** ## 1.进入本机目录并下载源码 如果有代理请设置代理，不然可能会超时或者慢。 ``` export http_proxys=http://127.0.0.1:9999 export http_proxy=http://127.0.0.1:9999 ``` ``` cd ~/git mango@mangodeMacBook-Pro git % hg clone https://hg.openjdk.java.net/jdk8u/jdk8u/ openjdk8u requesting all changes adding changesets adding manifests
