**1.安装编译所需依赖包**

sudo apt-get install libx11-dev libxext-dev libxrender-dev libxtst-dev libxt-dev
    sudo apt-get install libcups2-dev
    sudo apt-get install libfreetype6-dev
    sudo apt-get install libasound2-dev

如果报错，更新Ubuntu源(更新过程要成功，如果报错，自行百度)

apt-get update

**2.安装OpenJdk1.7**  
由于我们编译的是OpenJDK 8，所以，**Bootstrap JDK**最好采用OpenJDK 1.7版本的  
直接运行如下命令：

sudo apt-get install openjdk-7-jre
    sudo apt-get install openjdk-7-jdk

安装完成后，输入 java -version

java version "1.7.0_121"
    OpenJDK Runtime Environment (IcedTea 2.6.8) (7u121-2.6.8-1ubuntu0.12.04.3)
    OpenJDK 64-Bit Server VM (build 24.121-b00, mixed mode)

3.下载OpenJdk8源码包  
地址：[https://download.csdn.net/download/tiglle/10810465][https_download.csdn.net_download_tiglle_10810465]  
将包上传至Ubuntu，解压  
①进入OpenJdk8根目录：

cd /tiglle/openjdk/openjdk-8u40-src-b25-10_feb_2015/openjdk

②输入命令 `bash configure`

如果出现

configure: error: Could not find a C++ compiler. You might be able to fix this by running 'sudo apt-get install build-essential'

输入命令`sudo apt-get install build-essential`

如果出现

Build performance summary:
    * Cores to use:   2
    * Memory limit:   2627 MB
    * ccache status:  not installed (consider installing)

输入命令`sudo apt-get install ccache`

检查成功

    WARNING: The result of this configuration has overridden an older
    configuration. You *should* run 'make clean' to make sure you get a
    proper build. Failure to do so might result in strange build problems.

③开始编译 `sudo make`  
编译时间比较久。。。
