MAC编译OpenJDK8

当前环境

1. mac 10.12.5
2. 系统已经安装了JDK1.8.121

编译OpenJDK8大致流程

1. 下载OpenJDK8源码
2. 安装依赖软件
3. 进行编译
4. 编译中遇到的问题及解决方案

下载OpenJDK8源码

• 源码可以在官网上直接下载源码地址：OpenJdk8主页，
• 本文是直接在版本控制软件中直接牵出：OpenJDK8 Mercurial地址
• OpenJDK使用的Mercurial版本控制软件，所以需要安装Mercurial
• 安装Mercurial可视化软件SourceTree【可选】
• 通过SourceTree将OpenJDK8牵出到本地目录
• 命令行方式：

hg clone http://hg.openjdk.java.net/jdk8/jdk8 jdk8cd jkd8bash ./get_source.sh

安装依赖软件

• Xcode：直接在APP Store中搜索Xcode安装文件比较大
• Xcode-select：安装命令：xcode-select –install
• 进行x11链接

    sudo ln -s /usr/X11/include/X11 /usr/include/X11     or    sudo ln -s /usr/local/X11/include/X11 /usr/include/X11 

• XQuartz：下载地址
• 安装brew：命令行安装，安装完后先进行更新，更新命令：brew update

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

• 安装llvm，安装命令：brew install llvm
• 安装freetype，安装命令：brew freetype
• link llvm-gcc和llvm-g++，由于xcode目录下已经没有llvm-gcc和llvm-g++程序，而build jdk的时候会用到，所以需要link过去

sudo ln -s /usr/bin/llvm-g++ /Applications/Xcode.app/Contents/Developer/usr/bin/llvm-g++  sudo ln -s /usr/bin/llvm-gcc /Applications/Xcode.app/Contents/Developer/usr/bin/llvm-gcc 

进行编译

1. cd到源码根目录系jdk8
2. ./configure 如果找不freetype可以加上–with-freetype-include=/usr/local/include/freetype2 –with-freetype-lib=/usr/local/lib/

    ydcun-prodeMBP:jdk8 ydcun-pro$ ./configure --with-freetype-include=/usr/local/include/freetype2 --with-freetype-lib=/usr/local/lib/    Configure source code has been updated, checking time stamps    Running generated-configure.sh    configure: Configuration created at Tue May 30 08:08:13 CST 2017.    configure: configure script generated at timestamp 1389186094.    checking for basename... /usr/bin/basename    checking for bash... /bin/bash    checking for cat... /bin/cat    checking for chmod... /bin/chmod    checking for cmp... /usr/bin/cmp    checking for comm... /usr/bin/comm    省略……    ====================================================    A new configuration has been successfully created in    /Users/ydcun-pro/workspace/openjdk/jdk8/build/macosx-x86_64-normal-server-release    using configure arguments '--with-freetype-include=/usr/local/include/freetype2 --with-freetype-lib=/usr/local/lib/'.

1. 设置环境变量：./bash_profile
   中文注释删掉会有乱码，修改后重新加载： source ~/.bash_profile

    # 设定语言选项，必须设置    export LANG=C    # Mac平台，C编译器不再是GCC，是clang    export CC=clang    # 跳过clang的一些严格的语法检查，不然会将N多的警告作为Error    export COMPILER_WARNINGS_FATAL=false    # 链接时使用的参数    export LFLAGS='-Xlinker -lstdc++'    # 是否使用clang    export USE_CLANG=true    # 使用64位数据模型    export LP64=1    # 告诉编译平台是64位，不然会按32位来编译    export ARCH_DATA_MODEL=64    # 允许自动下载依赖    export ALLOW_DOWNLOADS=true    # 并行编译的线程数，编译时间长，为了不影响其他工作，我选择为2    export HOTSPOT_BUILD_JOBS=2    export ALT_PARALLEL_COMPILE_JOBS=2    # 是否跳过与先前版本的比较    export SKIP_COMPARE_IMAGES=true    # 是否使用预编译头文件，加快编译速度    export USE_PRECOMPILED_HEADER=true    # 是否使用增量编译    export INCREMENTAL_BUILD=true    # 编译内容    export BUILD_LANGTOOLS=true    export BUILD_JAXP=true    export BUILD_JAXWS=true    export BUILD_CORBA=true    export BUILD_HOTSPOT=true    export BUILD_JDK=true    # 编译版本    export SKIP_DEBUG_BUILD=true    export SKIP_FASTDEBUG_BUILD=false    export DEBUG_NAME=debug    # 避开javaws和浏览器Java插件之类的部分的build    export BUILD_DEPLOY=false    export BUILD_INSTALL=false

1. make all

   • 问题1

问题1：configure: error: GCC compiler is required解决方法：jdk8/common/autoconf/generated-configure.sh文件中注释两处代码：第20061，21640行#as_fn_error $? "GCC compiler is required. Try setting --with-tools-dir." "$LINENO" 5
