CentOS7下编译openjdk

CentOS7下编译openjdk

编译环境：

操作系统: CentOS7 64位

BootStrap JDK: 1.7.0_76

1. 下载openjdk源码

下载openjdk1.7源码 openjdk-7u40-fcs-src-b43-26_aug_2013.zip

2. 安装编译环境

安装alsa包

yum install alsa-lib-devel

安装cups-devel

yum install cups-devel

安装X相关的库

yum install libX*

安装g++

yum install gcc gcc-c++

安装freetype

rpm -ivh freetype-2.4.11-9.el7.x86_64.rpm 下载地址

安装ant

tar -zvxf apache-ant-1.9.6-bin.tar.gz 下载地址

设置环境变量

unset CLASSPATH

unset JAVA_HOME

// 语言选项，必须设置

export LANG=C

// Bootstrap JDK的安装路径，必须设置

export ALT_BOOTDIR=/usr/java/jdk1.7.0_76

// Ant的安装路径

export ANT_HOME=/opt/apache-ant-1.9.6

// 允许自动下载依赖

export ALLOW_DOWNLOADS=true

// 预编译

export USE_PRECOMPILED_HEADER=true

// 64位jdk

export ARCH_DATA_MODEL=64

// 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

// 编译内容

export SKIP_DEBUG_BUILD=false

export SKIP_FASTDEBUG_BUILD=true

export DEBUG_NAME=debug

// 输出路径

export ALT_OUTPUTDIR=/root/openjdk/build

编译检查

make sanity

若输出结果为：

Sanity check passed

，表示设置正确

执行编译

make

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

[root@localhost ~]# java -version

openjdk version “1.7.0-internal-debug”

OpenJDK Runtime Environment (build 1.7.0-internal-debug-root_2015_12_02_11_03-b00)

OpenJDK 64-Bit Server VM (build 24.0-b56-jvmg, mixed mode)
