2021-09-28—MacOS编译openjdk9

MacOS编译openjdk9

下载JDK源码文件：

方式一，Git clone：https://github.com/campolake/openjdk9.git

方式二，官方下载jdk源码zip包：http://jdk.java.net/

各个版本JDK下载地址汇总：https://blog.csdn.net/qq_23091073/article/details/83178848

以下命令均在openjdk9的路径下执行：

1、首先安装必要依赖：

brew install ccache
brew install freetype
brew install ant
brew install autoconf
brew install llvm
brew install binutils

2、配置configure权限：

chmod u+x configure

3、进行检查配置：

注意：参数--with-freetype=/usr/local/Cellar/freetype/2.11.0中的路径一定是你自己的安装路径。

sudo bash ./configure --with-target-bits=64 --with-freetype=/usr/local/Cellar/freetype/2.11.0 --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

配置xcode丢失的文件（Xcode 10以后删除了libstdc++库，转而使用libc++），
解决方法就是从github上下载库，然后设置环境变量后解决，此方法我编译过两次都通过。
克隆仓库：git clone https://github.com/imkiwa/xcode-missing-libstdc-.git，
执行仓库下的install.sh进行安装。
接下来进行环境变量的配置：

export CFLAGS="-I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/4.2.1"
export CXXFLAGS="-I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/4.2.1"
export LDFLAGS=-L/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/lib/
export LIBRARY_PATH=$LIBRARY_PATH:/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/lib/

4、执行make进行编译

sudo make all JOBS=8 ZIP_DEBUGINFO_FILES=0 COMPILER_WARNINGS_FATAL=false  CC=clang USE_CLANG=true LP64=1 LOG=debug  2>&1 | tee make_mac_x64.log

5、错误汇总

参考博客，这里有些常见的错误对应的解决方法：https://blog.csdn.net/lizhengjava/article/details/105629780

此博客也有一些需要更改cpp代码的错误的解决方法：https://blog.csdn.net/qq_25905629/article/details/107485000

其他错误2—-解决方法：

注释文件hotspot/src/share/vm/runtime/perfMemory.cpp第75~77行：

// if (SafepointSynchronize::is_at_safepoint() && !StatSampler::is_active()) {
//     PerfDataManager::destroy();
// }

解决方案：https://stackoverflow.com/questions/50678467/building-openjdk-9-on-mac-os/54954805

但是这样处理后，使用jstat监控JVM时可能会导致 内存泄露

6、编译成功结果

测试验证

ellisonpei@peimacbookpro bin % cd build/macosx-x86_64-normal-serverANDclient-slowdebug/jdk/bin
ellisonpei@peimacbookpro bin % ./java -version

控制台输出：

openjdk version "9-internal"
OpenJDK Runtime Environment (slowdebug build 9-internal+0-2021-09-28-085320.root.openjdk9-master)
OpenJDK 64-Bit Server VM (slowdebug build 9-internal+0-2021-09-28-085320.root.openjdk9-master, mixed mode)

7、使用Clion编译器进行断点调试

先去Jetbrains官网下载Clion下载软件。

下载链接：https://www.jetbrains.com/clion/

使用Clion打开openjdk9-master项目，添加Custom Build Application，然后配置target和Executable。

配置步骤具体参考博客：https://segmentfault.com/a/1190000040305260

最后断点启动，总是会断点到<unknown> 0x000000010ff59513,这时候

可以在点击 LLDB，输入
process handle SIGSEGV --stop=false
即可，这里告诉编译器忽略错误

然后跳过就会走到你的自定义断点处，就可以一步步调试了。
