在Windows11下编译openjdk 21

下载openjdk 20作为boot jdk，假设我下载解压后的路径如下

D:\Downloads\jdk-20.0.2_windows-x64_bin\jdk-20.0.2

首先下载Cygwin，因为这是在Windows中模拟UNIX，在安装程序界面选择要安装的包

autoconf make zip unzip perl bash awk grep sed diffutils git

第二安装Visual Studio 2022，要安装desktop C++，要包括msvc 143和Windows 11 SDK，或者Windows 10 SDK

第三将Windows的设置中，把语言改为英文

时间和语言->把使用Unicode UTF-8这个选项打开

如果不行就把Windows显示语言改为英语（美国）

在Windows菜单中选择x64 Native Tools Command Prompt for VS进入命令行，这是因为要使用VC++的编译器进行编译

C:\Program Files\Microsoft Visual Studio\2022\Professional>cd c:\cygwin64 c:\cygwin64>cd bin c:\cygwin64\bin>bash.exe --login

上述是在命令行中调用cywin

测试cl和link是否好用，一定要显示英文才可以

firew@JINGXIN-HONOR /cygdrive/d/openjdk $ cl Microsoft (R) C/C++ Optimizing Compiler Version 19.44.35222 for x64 Copyright (C) Microsoft Corporation. All rights reserved. usage: cl [ option... ] filename... [ /link linkoption... ] $ link link: missing operand Try 'link --help' for more information.

然后进入openjdk源码目录，切到jdk-17+30分支，创建debug编译脚本

#!/usr/bin/env bash# 设置环境变量exportBOOT_JDK="/d/Downloads/jdk-20.0.2_windows-x64_bin/jdk-20.0.2"exportFREETYPE_HOME="/c/msys64/mingw64"# 转换为Windows路径格式（如果需要）BOOT_JDK_WIN="D:\\Downloads\\jdk-20.0.2_windows-x64_bin\\jdk-20.0.2"FREETYPE_HOME_WIN="C:\\msys64\\mingw64"echo"Configuring OpenJDK 21..."# 配置命令bashconfigure\MAKE=/usr/bin/make\--with-debug-level=slowdebug\--with-native-debug-symbols=external\--with-toolchain-type=microsoft\--with-toolchain-path="/cygdrive/c/Program Files/Microsoft Visual Studio/2022/Professional/VC/Tools/MSVC/14.44.35207/bin/HostX64/x64"\--with-boot-jdk="$BOOT_JDK_WIN"\--disable-warnings-as-errors# 检查配置结果if[$?-eq0];thenecho"Configuration successful, starting build..."makeimagesJOBS=8#make CONF=windows-x86_64-server-slowdebug all JOBS=8elseecho"Configuration failed!"read-p"Press enter to continue..."exit1fi

如果要编译release版本，则采用以下脚本

#!/usr/bin/env bash# 设置环境变量exportBOOT_JDK="/d/Downloads/jdk-20.0.2_windows-x64_bin/jdk-20.0.2"exportFREETYPE_HOME="/c/msys64/mingw64"# 转换为Windows路径格式（如果需要）BOOT_JDK_WIN="D:\\Downloads\\jdk-20.0.2_windows-x64_bin\\jdk-20.0.2"FREETYPE_HOME_WIN="C:\\msys64\\mingw64"echo"Configuring OpenJDK 21..."#--with-freetype=bundled \#--with-freetype-include="$FREETYPE_HOME_WIN/include/freetype2" \#--with-freetype-lib="$FREETYPE_HOME_WIN/lib" \# 配置命令bashconfigure\MAKE=/usr/bin/make\--with-debug-level=release\--with-toolchain-type=microsoft\--with-toolchain-path="/cygdrive/c/Program Files/Microsoft Visual Studio/2022/Professional/VC/Tools/MSVC/14.44.35207/bin/HostX64/x64"\--with-boot-jdk="$BOOT_JDK_WIN"\--disable-warnings-as-errors# 检查配置结果if[$?-eq0];thenecho"Configuration successful, starting build..."makeimagesJOBS=8elseecho"Configuration failed!"read-p"Press enter to continue..."exit1fi
