sudo apt install mercurial
hg clone http://hg.openjdk.java.net/jdk8/jdk8 jdk8u
cd jdk8u
chmod 777 ./*
wget https://download.java.net/openjdk/jdk7u75/ri/jdk_ri-7u75-b13-linux-x64-18_dec_2014.tar.gz
tar xvf jdk_ri-7u75-b13-linux-x64-18_dec_2014.tar.gz
./configure –with-target-bits=64 –with-jvm-variants=server –with-debug-level=slowdebug –disable-zip-debug-info –with-boot-jdk=/your-pwd/soft/java-se-7u75-ri/ –with-memory-size=1024
参数解释:

–with-target-bits=64: 构建64的JDK

–with-jvm-variants=server :构建server模式的JDK

–with-debug-level=slowdebug: slowdebug带有更多的调试信息

–disable-zip-debug-info：禁止压缩调试信息，可以方便调试

–with-boot-jdk=/export/soft/java-se-7u75-ri/ ：表示boot jdk的路径，就是刚才下载的jdk7的路径
--with-memory-size=1024 表示1GB

sudo apt-get install libx11-dev libxext-dev libxrender-dev libxtst-dev libxt-dev

./get_source.sh

等待几分钟，时间可能需要很久
在运行 ./configure ，运行的过程需要的依赖很多，依次安装就好了。

vi hotspot/make/linux/makefiles/adjust-mflags.sh

gcc的版本过高

安装gcc和g++ 4.9版本

修改apt源：

sudo vi /etc/apt/sources.list

添加以下内容到文件末尾：

#install gcc 4.9

deb http://dk.archive.ubuntu.com/ubuntu/ xenial main

deb http://dk.archive.ubuntu.com/ubuntu/ xenial universe

更新源：

sudo apt-get update

安装4.9版本：

sudo apt install gcc-4.9

sudo apt install g++-4.9

管理多版本gcc：

sudo update-alternatives –install /usr/bin/gcc gcc /usr/bin/gcc-7 50
sudo update-alternatives –install /usr/bin/g++ g++ /usr/bin/g++-7 50
sudo update-alternatives –install /usr/bin/gcc gcc /usr/bin/gcc-4.9 20
sudo update-alternatives –install /usr/bin/g++ g++ /usr/bin/g++-4.9 20

切换到4.9版本：

sudo update-alternatives –config gcc

sudo update-alternatives –config g++

注意：切换完gcc的版本后需要重新运行之前命令

sh ./configure –with-target-bits=64 –with-jvm-variants=server –with-debug-level=slowdebug –disable-zip-debug-info –with-boot-jdk=/export/soft/java-se-7u75-ri/

再执行
vi hotspot/make/linux/makefiles/gcc.make
注释掉如下这行

./configure –with-target-bits=64 –with-jvm-variants=server –with-debug-level=slowdebug –disable-zip-debug-info –with-boot-jdk=/your-pwd/soft/java-se-7u75-ri/
最后 make images

1	codeql database create jdk_src --language=java --command="make images"

如果运行过程中下面错误，就是系统内存不够

CompileJavaClasses.gmk:316: recipe for target '/data/github/jdk-jdk8-b120/build/linux-x86_64-normal-server-release/jdk/classes/_the.BUILD_JDK_batch' failed
