Mac编译OpenJdk源码

本文最后更新于：2023-05-12 22:53 星期五

MacOs编译OpenJDK

  • 未强调目录，即本地仓库根目录
  • 编译Git Tag：jdk-21+21 # 本想编译jdk17，奈何17版本报错太多，无法解决，怀疑是xcode或系统版本问题，索性目前最新。

bash configure \
--with-debug-level=slowdebug  \
--with-jvm-variants=server  \
--with-target-bits=64 \
--with-boot-jdk=$JAVA_20_HOME

  • –with-debug-level=slowdebug #可选：release、fastdebug、slowdebug，越靠后debug信息越多，优化越少。

  • –with-jvm-variants=server #jvm模式：server、client、minimal、core、zero、custom

  • –with-target-bits=64 #指定编译32位还是64位的JVM

  • –with-boot-jdk=$JAVA_20_HOME # 系统export 配置的环境变量，我使用的是jdk20

补充

  • –with-conf-name=jdk-21+22-slowdebug 自定义名字，执行make指令，增加CONF=jdk-21+22-slowdebug 参数。例如make CONF=jdk-21+22-slowdebug images

导入Clion

生成 compile-commands.json ，Compile Commands参考Clion[彩蛋]文档[jetbrains]

Updating compile_commands.json
Finished building target 'compile-commands' in configuration 'macosx-x86_64-server-slowdebug'

#  make compile-commands 再 make all 生成的compile_commands.json  也可以

导入

  1. 使用Clion打开目录 ./build/macosx-x86_64-server-slowdebug/compile_commands.json 文件。

  2. 使用项目打开，等待Clion完成项目索引扫描

  3. 更改项目根目录为OpenJDK根目录，等待重新扫描索引。如下图

根据compile_commands.json导入项目
项目打开方式
更改根目录

配置

配置外部工具

ExtendedTools

  • make all

    #Program 和 Arguments 共同构成了所要执行的命令 “make all”

    Name: make
    Program: make
    Arguments: all
    Working directory: {项目的根目录/本地openjdk位置}

  • make clean 配置同 make all

  • make images 配置 同 make all

  • make 配置同 make all

运行/调试配置 （Run/Debug configuration）

RunDebugConfiguration

  • Run/Debug configuration

    Configuration

  • 编译jdk，修改jdk源码后编译源码使用。

    make-images

运行Debug

IDEA 引用 Native OpenJDK

  1. IDEA 新建工程，并修改JDK为编译好的jdk（build/macosx-x86_64-server-slowdebug/images/），将源码修改为OpenJdk根目录下的src目录。

    SDK1
    SDK2

  2. 修改jdk代码

    MAIN

  3. 执行 make images 编译jdk

    源码更目录执行make images 或在CLion执行预先配置好的make images即可。

    run-make-images1
    run-make-images1

  4. 运行测试代码看修改效果

解决方式 : 将 graphviz[graphviz官网]的 lib目录下 .dylib 文件映射到 /usr/local/lib/ 目录下

解决方式：执行以下命令即可。

# 执行 chown 根据实际情况更改

寻找到的变相解决方式，反正是意外的解决了make all 报错的问题。

感觉不是最终解决方式，但有没有更好的方式，如看到此贴的人知道，麻烦请告知一下更好的解决方案。

lldb报错：SIGSEGV (signal SIGSEGV) （涉及到C/C++相关内容，不明所以，完全是照猫画虎）

iShot_2023-05-10_01.10.55

解决办法是，在用户家目录创建.lldbinit，内容如下：

  • 第一种方法[lldbinit1]

    1
    2
    # 在compile_commands.json 同级目录添加经过测试无效，需要在系统 	`~/.lldbinit`目录下新建，原因未知。
    br set -n main -o true -G true -C "pro hand -p true -s false SIGSEGV SIGBUS"

  • 第二种方法[lldbinit2]

    1
    2
    #main.c是本地绝对路径
    breakpoint set --file /Users/../openjdk/src/java.base/share/native/launcher/main.c --line 98 -C "pro hand -p true -s false SIGSEGV SIGBUS" --auto-continue true

  • 第三种方法[lldbinit3]

    1
    break set -n main -C "process handle --pass true --stop false SIGSEGV" -C "process handle --pass true --stop false SIGBUS"

其他

关于在网上看到如下命令

3
bash configure --with-debug-level=slowdebug --with-jvm-variants=server
make CONF=macosx-x86_64-server-slowdebug compile-commands
make CONF=macosx-x86_64-server-slowdebug

关于CONF参数的作用，如果build目录下面只有一个配置信息，则可以省略。

补充说明 CONF=<config pattern>

点击查看CONF官方文档

出自文件：./make/InitSupport.gmk 第245行

CONF=
