老大哥:编译JDK好难呀,我要放弃Java了,我:别呀,看我的

一次又一次的编译JDK;

一次又一次的失败.

最终

冲破层层难关,来总结一下在Centos7环境下编译OpenJDK的过程.

你可能会问了:我看其他文章里都是要求的一下子装很多很多的软件的呀,在这里怎么一个也不安装了.

你也许翻了10篇文章有9篇文章都写了一堆下面这个玩意:

当然了,并不是不对,是根本不知道怎么来的.

这里我是故意放的一个图片,就是不让你直接复制,哈哈,复制不出来吧,那就对了,跟着我来!!!!!!!

我只想问你,你是不是有一头问号.

没关系,这篇文章让你彻底清醒

这篇文章就是来做你编译jdk的翻的最后的一个博客.

我想教会的你的是如何解决问题,并不是一下子帮你解决好.

这样子才能学到东西

一,创建放置源码的文件夹

因为咱们要编译的是jdk12,所以这里创建一个jdk12的文件夹,可以随意起名字

[root@TrueDei ~]# mkdir jdk12
[root@TrueDei ~]# cd jdk12/
[root@TrueDei jdk12]#

二,测试是否已经包含了jdk

如果已经存在,请删除或者卸载掉

[root@TrueDei ~]# java 
bash: java: 未找到命令
[root@TrueDei ~]#

三,如何获取Openjdk的源码

可以通过这个网站获取OpenJDK的源码:http://hg.openjdk.java.net/jdk/

你可以选择任意一个你喜欢的

在这里插入图片描述

你也可以根据自己的喜好,来选择要下载的压缩包的格式

在这里插入图片描述

这个地址就是咱们需要的,或者直接右击上面的格式复制链接地址:http://hg.openjdk.java.net/jdk/jdk12/archive/tip.tar.gz

在这里插入图片描述

四,下载jdk源码,并解压

首先你要确定你的Linux是否可以上网

在这里插入图片描述

下载源码我们使用的是wget,如果没有,可以安装一下

[root@TrueDei jdk12]# wget http://hg.openjdk.java.net/jdk/jdk12/archive/tip.tar.gz
bash: wget: 未找到命令
[root@TrueDei jdk12]# yum -y install wget

下载jdk的源码

[root@TrueDei jdk12]# wget http://hg.openjdk.java.net/jdk/jdk12/archive/tip.tar.gz

在这里插入图片描述

如果出现下面这个,则是没下载完全:

[root@TrueDei jdk12]# tar -zxf tip.tar.gz 

gzip: stdin: unexpected end of file
tar: 归档文件中异常的 EOF
tar: 归档文件中异常的 EOF
tar: Error is not recoverable: exiting now
[root@TrueDei jdk12]#

可以使用windows,或者使用其他物理机下载好,然后想办法传过去

我的物理机是Deepin,所以我可以使用scp命令拷贝过去

truedei@truedei:Downloads$ ll jdk12-06222165c35f.zip 
-rw-r--r-- 1 truedei truedei 180327483 5月  20 23:36 jdk12-06222165c35f.zip
truedei@truedei:Downloads$ 
truedei@truedei:Downloads$ scp jdk12-06222165c35f.zip  [email protected]:/root/jdk12/
[email protected]'s password: 
jdk12-06222165c35f.zip                                         100%  172MB  82.4MB/s   00:02    
truedei@truedei:Downloads$

因为需要使用unzip来解压,所以没有的同学先要安装一下

[root@TrueDei jdk12]# yum -y install unzip

解压

[root@TrueDei jdk12]# unzip jdk12-06222165c35f.zip

再次解压就没问题了

[root@TrueDei jdk12]# ll

drwxr-xr-x. 14 root root   217 5月   9 11:21 test
[root@TrueDei jdk12]#

进入到解压后的文件夹里

[root@TrueDei jdk12]# 
[root@TrueDei jdk12]# cd jdk12-06222165c35f
[root@TrueDei jdk12-06222165c35f]#

五,安装编译的此OpenJDK之前的版本

安装要编译的JDK的上一个版本JDK（因为编译JDK时要有一个编译期可使用的JDK，官方称作这个JDK叫Bootstrap JDK）

安装上一版本JDK，这里安装JDK11

可以使用一下命令来查看一下yum源的仓库里有哪些版本的

可以看到,只有6,7,8,11版本的java

[root@TrueDei jdk12-06222165c35f]# 
[root@TrueDei jdk12-06222165c35f]# yum search java | grep jdk

[root@TrueDei jdk12-06222165c35f]#

我们选择jdk11的安装

[root@TrueDei jdk12-06222165c35f]# 
[root@TrueDei jdk12-06222165c35f]# yum -y install java-11-openjdk-devel

安装好就会可以查看版本信息

[root@TrueDei jdk12-06222165c35f]# 
[root@TrueDei jdk12-06222165c35f]# java -version
openjdk version "11.0.7" 2020-04-14 LTS
OpenJDK Runtime Environment 18.9 (build 11.0.7+10-LTS)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.7+10-LTS, mixed mode, sharing)
[root@TrueDei jdk12-06222165c35f]#

六,安装必要的依赖

安装GCC 版本至少4.8以上，官方推荐版本7.8 或 CLang 3.2 以上

SCL（Software Collections）是为了给RHEL/CentOS 用户提供一种以方便、安全地安装和使用应用程序和运行时环境的多个（而且可能是更新的）版本的方式，同时避免把系统搞乱。与之相对的是第三方源，它们可能会在已安装的包之间引起冲突

[root@TrueDei jdk12-06222165c35f]# yum install -y centos-release-scl
[root@TrueDei jdk12-06222165c35f]# yum install -y devtoolset-7
[root@TrueDei jdk12-06222165c35f]# scl enable devtoolset-7 bash

下载的速度决定于自己的网速

七,编译

你可能会问了:我看其他文章里都是要求的一下子装很多很多的软件的呀,在这里怎么一个也不安装了.

我想教会的你的是如何解决问题,并不是一下子帮你解决好.

这样子才能学到东西

这里就安装额这些,咱们直接编译,边编译,边发现问题,边解决问题:

再来看一下当前的目录

[root@TrueDei jdk12-06222165c35f]# pwd

[root@TrueDei jdk12-06222165c35f]#

编译:

在Linux中以后的路还长,遇到这种问题一定是不可避免的,所以要好好看了,一定要学到.

一直到不报错为止

在这里插入图片描述

八,继续make

开始编译，编译完后，进入到jdk目录下的 ./build/配置名称/jdk 可以看到编译后的文件 (配置名称没有设置的话，会是编译的机器名)

这个时间可能会特别慢,等待吧,可以去刷一道算法题再回来

[root@TrueDei jdk12-06222165c35f]# make images

make完成之后是下面这个样子

在这里插入图片描述

九,测试成果

进入到编译后的jdk目录

[root@TrueDei jdk12-06222165c35f]# pwd
