#安装文档中描述的外部库要求（External Library Requirements）

yum install -y freetype-devel cups-devel libXtst-devel libXt-devel libXrender-devel libXi-devel alsa-lib-devel libffi-devel

#安装Build Tools Requirements

yum install -y autoconf

#提示缺少unzip，安装之

yum install -y unzip zip

#再次执行./configure提示configure: Could not find a valid Boot JDK. You might be able to fix this by running 'sudo yum install java-1.8.0-openjdk-devel'.

#尝试 yum install -y java-1.8.0-openjdk-devel

#但发现依然各种错误，提示需要10或者11，yum search openjdk-devel只有11

#详细原因参见Boot JDK Requirements

yum install -y java-11-openjdk-devel

#再次执行提示缺少gcc，建议安装开发工具包

yum groupinstall "Development Tools"

#再次执行提示缺少fontconfig

yum install -y fontconfig-devel

 

 

chmod 777 configure

./configure

make

 

编译成功提示：

Stopping sjavac server

Finished building target 'default (exploded-image)' in configuration 'linux-x86_64-normal-server-release'

 

 

此时，在jdk11/build/linux-x86_64-normal-server-release目录下，有个jdk目录，这里面就是最新构建的OpenJDK，进入里面的bin目录，再执行命令./java -version
