1-CentOS7.3编译Jdk7.0

63 阅读 0 评论
我是靠谱客的博主 强健白羊，最近开发中收集的这篇文章主要介绍1-CentOS7.3编译Jdk7.0，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

1-CentOS7.3编译Jdk7.0

JDK源码下载 http://openjdk.java.net/install/
一、系统环境
	cat /etc/redhat-release  #查询发行版本
	uname -m
	uname -r

在这里插入图片描述

二、编译环境配置
2.1安装Apache Ant (版本要求1.7.1以上)

下载apache-ant-1.9.9-bin.tar.gz安装包上传到 /usr/local目录下，
在这里插入图片描述

执行命令，设置ant环境

	tar -xvf apache-ant-1.9.9-bin.tar.gz #解压ant安装包
	ln -s /usr/local/apache-ant-1.9.9/bin/ant /usr/bin/ant #安装ant到本地
	ant #查询ant是否可用

在这里插入图片描述

2.2安装Bootstrap JDK (尽量不要使用跟目标版本相同的版本或者更高版本)

这里要进行编译的jdk版本为openjdk-7u40，所以我选择的Bootstrap JDK的版本为jdk-6u45-linux-x64.bin
从oracle官网下载jdkjdk-6u45-linux-x64.bin
然后上传到/usr/local目录下
在这里插入图片描述

解压安装到local中

	chmod a+x jdk-6u45-linux-x64.bin  
	./jdk-6u45-linux-x64.bin

注：检查系统是否默认安装了openJDK环境

2.3 安装GCC依赖包
#安装alsa包
yum -y install alsa-lib-devel
安装cups-devel
yum -y install cups-devel
安装X相关的库 
yum -y install libX*
yum -y install libXi-devel
安装gcc
yum -y install gcc gcc-c++
安装freetype 
yum -y install freetype
安装stdc库，(不安装会报cannot access 'libjvm.so': No such file or directory错误)
yum install libstdc++-static
2.4 配置要编译的环境变量
2.4.1 取消java环境变量

如果之前设定了JAVA_HOME和CLASSPATH两个环境变量，在编译前必须取消，否则在Makefile脚本中检查到有这两个变量存在，会有警告提示

	unset JAVA_HOME
	unset CLASSPATH
2.4.2 语言选项，必须设置
	export LANG=C
2.4.3 Bootstrap JDK的安装路径，必须设置
	export ALT_BOOTDIR=/usr/local/jdk1.6.0_45
2.4.4 Ant的安装路径
	export ANT_HOME=/usr/local/apache-ant-1.9.9
2.4.5 允许自动下载依赖
	export ALLOW_DOWNLOADS=true
2.4.6 使用预编译头文件，不加这个编译会更慢一些
	export USE_PRECOMPILED_HEADER=true
2.4.7 并行编译的线程数，设置为和CPU内核数量一致即可
	export HOTSPOT_BUILD_JOB=4 
	export ALT_PARALLEL_COMPILE_JOBS=4
2.4.8 64位jdk
	export ARCH_DATA_MODEL=64
2.4.9 比较本次build出来的映像与先前版本的差异(这对我们来说没有意思)

必须设置为false，否则sanity检查会报缺少先前版本JDK的映像的错误提示
如果已经设置dev或者DEV_ONLY=true 这个不显式设置也行

	export SKIP_COMPARE_IMAGES=false
2.4.10 编译内容
	export BUILD_LANGTOOLS=true
	# export BUILD_JAXP=false
	# export BUILD_JAXWS=false
	# export BUILD_CORBA=false
	# export BUILD_HOTSPOT=true
	export BUILD_JDK=true
2.4.11 编译的版本
	export SKIP_DEBUG_BUILD=false 
	export SKIP_FASTDEBUG_BUILD=true 
	export DEBUG_NAME=debug
2.4.12 把它设置为false可以避开javaws和浏览器java插件之类的部分的build
	export BUILD_DEPLOY=false
2.4.13 把它设置为false就不会build出安装包，因为安装包里有些奇怪的依赖

但即便不build出它也已经能得到完整的JDK映像，所以还是别build它好了

	export BUILD_INSTALL=false
2.4.14 编译结果所存放的路径
	export ALT_OUTPUTDIR=/home/jdkbuild

三、开始编译
3.1 上传jdk源码，解压到本地

3.2 编译检查
	make sanity

在这里插入图片描述

Sanity check passed.

若输出结果为：Sanity check passed，表示设置正确

3.3 编译前修改源码
3.3.1 日期修改 (所有设计到时间的修改为10年以内的时间)
错误提示：＃　time is more than 10 years from present
jdk/src/share/classes/java/util/CurrencyData.properties

修改108行
AZ=AZM;2009-12-31-20-00-00;AZN
修改381行
MZ=MZM;2009-06-30-22-00-00;MZN
修改443行
RO=ROL;2009-06-30-21-00-00;RON
修改535行
TR=TRL;2009-12-31-22-00-00;TRY
修改561行
VE=VEB;2009-01-01-04-00-00;VEF
3.3.2 修改虚拟机make文件hotspot/make/linux/Makefile
这个会导致编译jvm失败，报Err 2，不支持的操作系统，原因是不支持当前linux内核版本
hotspot/make/linux/Makefile  234行
SUPPORTED_OS_VERSION = 2.4% 2.5% 2.6% 3%
改为
SUPPORTED_OS_VERSION = 2.4% 2.5% 2.6% 3% 4%
3.3 执行编译
	make 2>&1 | tee $ALT_OUTPUTDIR/build.log

说明：当检查过程看到"Sanity check passed",说明检查过程通过，可以输入"make"执行整个OpenJDK编译，(make不加参数，默认make all)
在这里插入图片描述

配置debug版jdk
/root/openjdk/build-debug/j2sdk-image下内容为debug版jdk，将其复制到%JAVA_HOME%下，替换Oracle JDK。
查看jdk版本信息

	java -version
