• 安装各种工具

需要什么安装什么，不需要可以不安装。有些安装跟老版本的xcode可能有冲突。

sudo xcode-select --install

brew install freetype

brew install mercurial
brew install ant
brew install ccache
brew install autoconf

brew install binutils

 gcc、g++

• 安装xcode

在应用商业中安装。

• 下载源码

# 经常失败
hg clone http://hg.openjdk.java.net/jdk8u/jdk8u-dev/

建议早上下载github，非常快： 

GitHub - AdoptOpenJDK/openjdk-jdk8u: JDK8u mirror from mercurial

• 修改脚本hotspot/make/bsd/makefiles/gcc.make

（无必要？）hotspot/make/bsd/makefiles/gcc.make注释：

# Compiler warnings are treated as errors
# ifneq ($(COMPILER_WARNINGS_FATAL),false)
#   WARNINGS_ARE_ERRORS = -Werror
# endif

clang: error: unknown argument: ‘-fpch-deps‘_柳鲲鹏-CSDN博客

修改脚本generate-configigure.sh
