构建 JVM(HotSpot) 源码调试环境(OpenJDK8)

原本想在 Windows 下编译调试,但过程中遇到了诸多错误(老是报路径错误。。。),最后只好放弃。

此次记录调试的方法为 CentOS7 上编译,Windows 上使用 Clion 远程调试(也可直接在 CentOS7 桌面环境直接调试,速度快)。

 

一、下载源码(OpenJDK8)

yum 源使用的是阿里的 https://opsx.alibaba.com/mirror?lang=zh-CN

这里使用 mercurial(类似 Git 的版本控制系统) 下载源码,方便更新。

下面网址可以下载 mercurial 较新的版本。

https://mercurial.selenic.com/wiki/ChineseDownload

https://www.mercurial-scm.org/wiki/Download

# 或者 yum install hg -y
yum install mercurial -y

# 下载源码,目标目录需要为空
hg clone http://hg.openjdk.java.net/jdk8u/jdk8u /opt/jdk8u

# 更新代码,操作和 Git 类似
hg pull

# 获取完整源码(需要在源码目录下执行,下载时间较长,一次可能下载不成功,多试几次)
cd /opt/jdk8u/
sh get_source.sh


# 完全下载成功的打印信息。若输出中出现回滚字样,即代表下载过程中出错了,需重新执行下载脚本

这里手动执行多次比较麻烦,自己写了个小脚本,循环执行。

#!/bin/bash

for i in {1..28}
do
cd /opt/jdk8u/;
sh ./get_source.sh;
done

 

二、编译源码

Linux 下编译比 Windows 下简单太多。

https://hg.openjdk.java.net/jdk8u/jdk8u/raw-file/945f4ae40e43/README-builds.html

构建 JDK 8 需要使用 Update 7 或更高版本的 JDK 7 版本。JDK 8 开发人员不应使用 JDK 8 作为引导 JDK,以确保 JDK 8 依赖关系不会引入使用 JDK 7 构建的系统部分。 

# 查询
yum list installed | grep jdk
rpm -qa | grep jdk

# 卸载
yum remove -y xxxxxxx

# 验证
java -version

# -bash: java: 未找到命令

# 安装 JDK7
# https://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html
tar -zxf jdk-7u80-linux-x64.tar.gz -C /opt/

配置

cd /opt/jdk8u/
chmod +x configure

# 直接执行配置,看看缺少什么工具或参数,按照错误提示安装和添加参数即可
./configure

# 安装编译所需工具包
yum install -y unzip zip libXtst-devel libXt-devel libXrender-devel cups-devel freetype-devel alsa-lib-devel fontconfig-devel
yum groupinstall -y "Development Tools"

# 配置编译环境
./configure --with-boot-jdk=/opt/jdk1.7.0_80/

configure 帮助文档

Running generated-configure.sh
`configure' configures OpenJDK jdk8 to adapt to many kinds of systems.

Usage: /opt/jdk8u/configure [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print `checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for `--cache-file=config.cache'
  -n, --no-create         do not create output files

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX [/usr/local]

By default, `make install' will install all the files in `/usr/local/bin', `/usr/local/lib' etc.  You can specify an installation prefix other than `/usr/local' using `--prefix', for instance `--prefix=$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]

Please be aware that, when cross-compiling, the OpenJDK configure script will
generally use 'target' where autoconf traditionally uses 'host'.

Also note that variables must be passed on the command line. Variables in the
environment will generally be ignored, unlike traditional autoconf scripts.

编译

# ZIP_DEBUGINFO_FILES=0 生成调试信息文件 libjvm.debuginfo,否则会被压缩成 libjvm.diz,debug 时只能看到汇编代码,不能跟进源码
# ENABLE_FULL_DEBUG_SYMBOLS=1 生成调试符号,可不加,不影响调试
# 编译
make all ZIP_DEBUGINFO_FILES=0 ENABLE_FULL_DEBUG_SYMBOLS=1

make 帮助文档

OpenJDK Makefile help
=====================

Common make targets
.  make [default]         # Compile all product in langtools, hotspot, jaxp, jaxws, corba and jdk
.  make all               # Compile everything, all repos and images
.  make images            # Create complete j2sdk and j2re images
.  make docs              # Create javadocs
.  make overlay-images    # Create limited images for sparc 64 bit platforms
.  make profiles          # Create complete j2re compact profile images
.  make bootcycle-images  # Build images twice, second time with newly build JDK
.  make install           # Install the generated images locally
.  make clean             # Remove all files generated by make, but not those generated by configure
.  make dist-clean        # Remove all files, including configuration
.  make help              # Give some help on using make
.  make test              # Run tests, default is all tests (see TEST below)

Targets for specific components
(Component is any of langtools, corba, jaxp, jaxws, hotspot, jdk, nashorn, images, overlay-images, docs or test)
.  make        # Build  and everything it depends on.
.  make -only  # Build  only, without dependencies. This is faster but can result in incorrect build results!
.  make clean- # Remove files generated by make for 

Useful make variables
.  make CONF=             # Build all configurations (note, assignment is empty)
.  make CONF=  # Build the configuration(s) with a name matching 
.  make LOG=    # Change the log level from warn to  Available log levels are: 'warn' (default), 'info', 'debug' and 'trace' To see executed command lines, use LOG=debug
.  make JOBS=          # Run  parallel make jobs Note that -jN does not work as expected!
.  make test TEST=  # Only run the given test or tests, e.g. make test TEST="jdk_lang jdk_net"

三、Windows 远程调试

CentOS7 端

yum remove -y cmake gdb
yum install -y gcc gcc-c++ make wget

# 安装 cmake,yum 源安装的版本较低
cd /opt/
wget https://cmake.org/files/v3.14/cmake-3.14.5.tar.gz
tar -zxf cmake-3.14.5.tar.gz
cd cmake-3.14.5
# 默认安装在 /usr/local/share/,可执行文件在 /usr/local/bin/
./bootstrap && make && make install
ln -s /usr/local/bin/cmake /usr/bin/cmake
cmake -version

# 安装 gdb
# 这里可以找到 gdb 镜像站点 https://www.gnu.org/software/gdb/download/
# 这里下载 texinfo 新版本 http://ftp.gnu.org/gnu/texinfo/
yum install -y texinfo
cd /opt/
wget https://mirrors.ustc.edu.cn/gnu/gdb/gdb-8.2.1.tar.gz
tar -zxf gdb-8.2.1.tar.gz
cd gdb-8.2.1
# 之前若出现过编译错误需要删掉(有缓存),重新解压编译
# 默认安装在 /usr/local/share/,可执行文件在 /usr/local/bin/
./configure && make && make install
ln -s /usr/local/bin/gdb /usr/bin/gdb
gdb -ver

 

Windows 端

首先用 Clion 新建一个空项目

远程调试

构建 JVM(HotSpot) 源码调试环境(OpenJDK8)_第1张图片

同步代码(windows 上的代码需要和 CentOS 上的代码一样)

连接信息

构建 JVM(HotSpot) 源码调试环境(OpenJDK8)_第2张图片

对应目录,本地目录为新建的 Hello World 项目路径

构建 JVM(HotSpot) 源码调试环境(OpenJDK8)_第3张图片

同步时要排除的本地目录

构建 JVM(HotSpot) 源码调试环境(OpenJDK8)_第4张图片

 下载远程代码

构建 JVM(HotSpot) 源码调试环境(OpenJDK8)_第5张图片

构建 JVM(HotSpot) 源码调试环境(OpenJDK8)_第6张图片

关闭项目,用载入的方式重新打开项目

构建 JVM(HotSpot) 源码调试环境(OpenJDK8)_第7张图片

设置远程调试,地址为 CentOS 地址,端口随意

构建 JVM(HotSpot) 源码调试环境(OpenJDK8)_第8张图片

 在 CentOS 上启动 GDB,端口与上面对应

yum install gdb-gdbserver -y

gdbserver :1234 /opt/jdk8u/build/linux-x86_64-normal-server-release/jdk/bin/java -version

打上断点,启动的 DeBug(比较慢,载入 libjvm.debuginfo 的时候)

四、CentOS 桌面本地调试

只调试 JVM 可以直接导入 hotspot 项目,速度快点

配置调试
