windows环境下编译OpenJDK12

环境:Windows11

目录:

1、下载OpenJDK12源码

下载地址:

https://hg.openjdk.org/jdk/jdk12

点击zip下载到本地。

解压到本地。

Tip:注意本地路径中最好不要包含中文或空格。

2、阅读一遍doc/building.html

如果只是想构建JDK,又没耐心看完那么多内容,只要看 TL;DR (Instructions for the Impatient) 部分的内容就可以了

构建步骤主要为以下5步:

1、获取源码(http://hg.openjdk.java.net/jdk/jdk)

2、运行配置(bash configure)

3、运行make(make images)

4、验证是否构建成功(./build/*/images/jdk/bin/java -version)

5、运行基本测试(make run-test-tier1)

3、安装CYGWIN

CYGWIN是一个用于在windows上模拟UNIX或LINUX环境的软件,在其上可使用GNU工具集在Windows上进行嵌入式系统开发。

之所以要下载这个软件,是因为后面编译OpenJDK的时候,需要用GNU Make来执行Makefile文件。

下载地址:
Cygwin

安装教程:

4、安装Visual Studio 2022(C++编译器)

官网下载地址:https://visualstudio.microsoft.com/zh-hans/vs/

5、配置依赖

打开控制台,输入 bash ,进入Bourne Again Shell环境:

进入OpenJDK12源码解压后的路径,输入 bash configure:

编译FastDebug版、仅含Server模式的HotSpot虚拟机:

bash configure --enable-debug --with-jvm-variants=server

Tip:如果之前执行过配置命令,需要先清除一下目录:make dist-clean

配置踩坑合集

报错1:

Untitled 4.png

configure: Your path contains Windows tools (C:\Windows\system32) before your unix (cygwin or msys) tools. configure: This will not work. Please correct and make sure /usr/bin (or similar) is first in path. configure: error: Cannot continue configure exiting with result code 1

解决方案1:

bash --login -i 进入shell环境

报错2:

configure: Could not find a valid Boot JDK.
configure: error: Cannot continue
configure: This might be fixed by explicitly setting --with-boot-jdk
configure exiting with result code 1

解决方案2:

下载JDK11:https://www.oracle.com/java/technologies/downloads/#java11

安装完成后,执行:

bash configure --enable-debug --with-jvm-variants=server --with-boot-jdk=/cygdrive/d/jdk11

指定boot jdk路径:-with-boot-jdk=/cygdrive/d/jdk11

报错3:

configure: Cannot locate a valid Visual Studio installation, checking current environment
checking for Visual Studio variables... not found
configure: Cannot locate a valid Visual Studio or Windows SDK installation on disk,
configure: nor is this script run from a Visual Studio command prompt.
configure: Try setting --with-tools-dir to the VC/bin directory within the VS installation
configure: or run "bash.exe -l" from a VS command prompt and then run configure from there.
configure: error: Cannot continue
configure exiting with result code 1

解决方案3:

bash configure --enable-debug --with-jvm-variants=server --with-boot-jdk=/cygdrive/d/jdk11 --with-tools-dir=/cygdrive/d/software/vs2019/VC/Auxiliary/Build

指定:-with-tools-dir=/cygdrive/d/software/vs2019/VC/Auxiliary/Build

同时注释掉OpenJDK12源码中make/autoconf/toolchain_windows.m4文件中的这句:

#VS_ENV_CMD=""

以及make/autoconf/toolchain.m4中的:

#AC_MSG_ERROR([A $TOOLCHAIN_TYPE compiler is required. Try setting --with-tools-dir.])

报错4:

configure: Rewriting OBJDUMP to "/usr/bin/objdump"
configure: error: Target CPU mismatch. We are building for x86_64 but CL is for "□□"; expected "x64".
configure exiting with result code 1

解决方案4:

在make/autoconf/toolchain.m4中找到Target CPU mismatch对应的AC_MSG_ERROR,改成AC_MSG_NOTICE。

报错5:

configure: Rewriting CYGWIN_VC_INSTALL_DIR to "/cygdrive/d/software/vs2019/VC"
ls: cannot access '/cygdrive/d/software/vs2019/VC/Redist/MSVC/*/x64/Microsoft.VC141.CRT/vcruntime140.dll': No such file or directory

no
configure: error: Could not find any dlls in /cygdrive/c/progra~2/wi3cf2~1/10/Redist/ucrt/DLLs/x64
configure exiting with result code 1

解决方案5:

toolchain_window.m4文件中的

UCRT_DLL_DIR="$CYGWIN_WINDOWSSDKDIR/Redist/ucrt/DLLs/$dll_subdir"

中间加上对应的版本号:

UCRT_DLL_DIR="$CYGWIN_WINDOWSSDKDIR/Redist/10.0.19041.0(版本号,在c/progra~2/wi3cf2~1/10/Redist下)/ucrt/DLLs/$dll_subdir"

再次执行:

bash configure --enable-debug --with-jvm-variants=server --with-boot-jdk=/cygdrive/d/jdk11 --with-tools-dir=/cygdrive/d/software/vs2019/VC/Auxiliary/Build

终于配置成功:

6、编译

先执行make clean清除旧配置

执行make images编译:

编译踩坑合集

报错1:

windows环境下编译OpenJDK12_第6张图片

解决1:

摸进e/jdk12-06222165c35f/build/windows-x86_64-server-fastdebug/make-support/failure-logs的错误日志里看看:

windows环境下编译OpenJDK12_第7张图片

这个test_json.cpp文件里有语法错误,是文件编码的问题,把文件编码改为utf-8-bom格式。

再次执行make clean和make images:

报错2:

Untitled 9.png

解决2:

看到test_json.cpp的357和363等行里都有一个小雪人字符:

把所有雪人字符都替换成普通字母,再次执行make clean和make images:

报错3:

windows环境下编译OpenJDK12_第9张图片

解决3:

找到methodMatcher.cpp,在240行后加上这三句:

Untitled 12.png

    #pragma warning(disable: 4819)
    #pragma warning(disable: 4778)
    #pragma warning(disable: 4474)

报错4:

error C2873: “Do_Not_Use_realloc_Use_safe_Realloc_Instead”: 符号不能用在 using 声明中

解决4:

找到src\java.desktop\windows\native\libawt\windows\alloc.h,将文件格式改为utf-8-bom。

并将87行开始的下面这三句注释掉:

#define malloc Do_Not_Use_malloc_Use_safe_Malloc_Instead
#define calloc Do_Not_Use_calloc_Use_safe_Calloc_Instead
#define realloc Do_Not_Use_realloc_Use_safe_Realloc_Instead

解决5:

参见 windows 平台编译openjdk12 - 乐途 - 博客园

make -v,检查一下Cygwin里make的版本,我的版本不知道什么时候改成了4.4,在Cygwin里卸载掉就可以了。

解决完所有报错后,执行 make images

编译成功
