警告??:本文耗时很长,先做好心理准备;编译openjdk源码需要很大的耐心,因为要踩很多坑,解决很多问题,本人从编译开始到结束用了两天时间,按照本篇教程踩坑会少许;谢谢观看

 

一、获取openjdk源码:

官网地址: http://jdk.java.net/

二、准备环境

安装 homwbrew:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”

 安装依赖:

brew install ccache  //加速编译
brew install freetype //字体引擎,编译过程中会被依赖到

 

三:环境编译(此处需要注意,mac系统版本与xcode版本及openjdk版本要相对应,否则会出现很多问题!!!

Mac os: 10.14.4
 
xcode:9.2
  下载xcode的官方链接:Sign In - Apple ( 直接搜索9.2版本, 然后下载安装)
 
编译:
./configure --with-target-bits=64 --with-freetype=/usr/local/Cellar/freetype/2.10.1 --enable-ccache --with-jvm-variants=server,client --with-boot-jdk-jvmargs="-Xlint:deprecation -Xlint:unchecked" 
--disable-warnings-as-errors --with-debug-level=slowdebug 2>&1 | tee configure_mac_x64.log

 注意: 将--with-freetype指向你自己的freetype安装路径, 可能会出现权限不足情况: 请在./config加上 -bash  (或者自行查找解决方案)

 

输出如下内容,基本就说明你的环境没问题了:

A new configuration has been successfully created in
/Users/yourname/jdk9/build/macosx-x86_64-normal-serverANDclient-slowdebug
using configure arguments --with-target-bits=64 --with-freetype=/usr/local/Cellar/freetype/2.9.1 --enable-ccache --with-jvm-variants=server,client --with-boot-jdk-jvmargs=-Xlint:deprecation -Xlint:unchecked --disable-warnings-as-errors --with-debug-level=slowdebug.

Configuration summary:
* Debug level:    slowdebug
* HS debug level: debug
* JDK variant:    normal
* JVM variants:   server client
* OpenJDK target: OS: macosx, CPU architecture: x86, address length: 64
* Version string: 9-internal+0-adhoc.daiyongzhi.jdk9 (9-internal)

Tools summary:
* Boot JDK:       java version "1.8.0_101" Java(TM) SE Runtime Environment (build 1.8.0_101-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode)  (at /Library/Java/JavaVirtualMachines/jdk1.8.0_101.jdk/Contents/Home)
* Toolchain:      clang (clang/LLVM from Xcode 9.2)
* C Compiler:     Version 9.0.0 (at /usr/bin/clang)
* C++ Compiler:   Version 9.0.0 (at /usr/bin/clang++)

Build performance summary:
* Cores to use:   8
* Memory limit:   16384 MB
* ccache status:  Active (3.5)

NOTE: You have requested to build more than one version of the JVM, which
will result in longer build times.

 

进行编译 openjdk1.9:

export LANG=C

make all LOG=debug  2>&1 | tee make_mac_x64.log

如果一切顺利,看到此结果就算编译成功了:

最后,验证一下:

cd openjdk/build/macosx-x86_64-normal-serverANDclient-slowdebug/jdk/bin
执行: ./java -version

警告??:编译过程中遇到的问题(此处列举几次常见错误,如若出现其他错误请自行查找解决方案):

总结一下编译过程中遇到的问题:

vi src/share/vm/memory/virtualspace.cpp (char *):

技术图片

vi src/share/vm/opto/loopPredicate.cpp (const TypeInt *):

技术图片

vi src/share/vm/opto/loopPredicate.cpp (const TypeInt *):

修改报错信息( 错误解决方案):

#1\. src/hotspot/share/memory/virtualspace.cpp # l585
if (base() != NULL) {
#
2\. src/hotspot/share/opto/lcm.cpp # l42 if (Universe::narrow_oop_base() != NULL) { // Implies UseCompressedOops.

#3\. src/hotspot/share/opto/loopPredicate.cpp # l915 assert(rng->Opcode() == Op_LoadRange || iff->is_RangeCheck() || _igvn.type(rng)->is_int()->_lo >= 0, "must be");

 

四、编译成功之后进行调试:

1.编写Java程序并使用自己编译的openjdk版本
 
修改idea编译器的jdk: 改为build/macosx-x86_64-normal-serverANDclient-slowdebug/images/jdk
 

 java代码:

public class Main {
    public static int size_1m = 1024*1024;
    public static List<byte[]> list = new ArrayList<>();
    public static void main(String[] args) throws Exception {
        System.out.println("Hello World!");
        for(int i=0;i<10;i++){
            System.out.println(i+1);
            list.add(new byte[size_1m]);
            Thread.sleep(1000L);
        }
    }
}

  

配置idea虚拟机参数:

-XX:NewSize=6m
-XX:SurvivorRatio=4
-XX:MaxNewSize=6m
-Xlog:gc*:stdout:time,level,tags
-XX:+UseParallelGC

位置如下图所示:

然后运行:

2.通过运行Java程序调试openjdk: 

将openjdk目录下的hotspot倒入到CLion

配置参数并运行:

技术图片

 

 

 

Executable是你编译生成的java命令,如我的目录是 build/macosx-x86_64-normal-serverANDclient-slowdebug/images/jdk/bin/java 
Program arguments就是你启动Java程序的参数,用IDEA运行上边编写的Java程序时,IDEA会打印运行指令如下:
/Users/yourname/jvm/openjdk/build/macosx-x86_64-normal-serverANDclient-slowdebug/images/jdk/bin/java -XX:NewSize=6m -XX:SurvivorRatio=4 -XX:MaxNewSize=6m -Xlog:gc*:stdout:time,level,tags -XX:+UseParallelGC -Dfile.encoding=UTF-8 -classpath /Users/yourname/IdeaProjects/mytest_projects/test_myjdk9/out/production/test_myjdk9 Main

与java联调:

Compile java:

Build Jvm:

  参数:

COMPILER_WARNINGS_FATAL=false
LFLAGS="‘-Xlinker -lstdc++‘"
CC=clang
USE_CLANG=true
LP64=1

 

随便修改源码方法,并在java源码调用(此处修改了openjdk源码的获取时间方法),展现效果如下:

如上所示:整个编译了及联调完毕,可以进行对源码为所欲为了;


 

附赠:centOs下编译openjdk:(该方法由好友提供,本人未真正测试,仅供参考):

1、安装代码管理工具mercurial/获取自己获取代码包
2、安装插件:
yum install alsa-lib-devel cups-devel libX* gcc gcc-c++ freetype-devel libstdc++-static ant make
3、查看当前路径
[***@VM_0_3_centos openjdk-jdk8u-jdk8u]$ pwd
/home/liangding/openjdk-jdk8u-jdk8u
[***@VM_0_3_centos openjdk-jdk8u-jdk8u]$ 
4、修改参数配置
[***@VM_0_3_centos openjdk-jdk8u-jdk8u]$ chmod +x configure
[***@VM_0_3_centos openjdk-jdk8u-jdk8u]$  ./configure —prefix=/home/liangding/jdk8u —enable-debug
5、编译
[***@VM_0_3_centos openjdk-jdk8u-jdk8u]$ make 
看到以下信息表示编译成功
## Finished jdk (build time 00:06:20)
—— Build times ———
Start 2019-07-08 22:07:16
End   2019-07-08 22:36:47
00:00:52 corba
00:20:13 hotspot
00:00:33 jaxp
00:00:42 jaxws
00:06:20 jdk
00:00:51 langtools
00:29:31 TOTAL
————————————
6、测试编译后生成jdk的路径
[***@VM_0_3_centos build]$ pwd
/home/liangding/openjdk-jdk8u-jdk8u/build
[***@VM_0_3_centos build]$ ls -lrt
total 4
drwxrwxr-x 9 liangding liangding 4096 Jul  8 22:30 linux-x86_64-normal-server-fastdebug
7、写一个测试程序
[***@VM_0_3_centos ~]$ ls -lrt
total 127804
-rw-rw-r————————————  1 liangding liangding 130719042 Jul  8 21:09 jdk8u.zip
drwxrwxr-x  2 liangding liangding      4096 Jul  8 21:48 jdk8u
drwxrwxr-x 14 liangding liangding      4096 Jul  8 21:53 openjdk-jdk8u-jdk8u
-rw-rw-r————————————  1 liangding liangding       147 Jul  8 22:41 HelloWorld.java
-rw-rw-r————————————  1 liangding liangding       432 Jul  8 22:45 HelloWorld.class
[***@VM_0_3_centos ~]$ cat HelloWorld.java
public class HelloWorld {
        public static void main(String[] args) {
                System.out.println(“HelloWorld openJDK”);
        }
}
8、测试
[***@VM_0_3_centos ~]$ ./openjdk-jdk8u-jdk8u/build/linux-x86_64-normal-server-fastdebug/jdk/bin/javac HelloWorld.java
9、运行
 [***@VM_0_3_centos ~]$ ./openjdk-jdk8u-jdk8u/build/linux-x86_64-normal-server-fastdebug/jdk/bin/java HelloWorld 
HelloWorld openJDK
[***@VM_0_3_centos ~]$
