CentOS 6.5上編譯安裝OpenJDK7源碼

日期：2017/2/28 14:01:44 编辑：Linux教程

采用開源的OpenJDK版本，獲取其源碼的方式有兩種：

通Mercurial代碼版本管理工具從Repository中直接取得源碼，但是速度太慢，需要花費數小時
直接下載官方打包好的源碼包（推薦）

下載源碼openjdk-7u6-fcs-src-b24-28_aug_2012.zip，解壓，下載地址如下:

http://www.java.net/download/openjdk/jdk7u6/promoted/b24/openjdk-7u6-fcs-src-b24-28_aug_2012.zip

本次編譯采用的是64位的OS，編譯也是64位的JDK，內存至少需要512MB

1.基本流程

（閱讀README和README-builds.html）

README-builds.html中包含有詳細的安裝信息，最好能完整的閱讀一下。

2.安裝基礎軟件包

我的CentOS6.5安裝在vmware10上，安裝時使用最小化(Minimal)安裝

[root@localhost ~]# cat /etc/RedHat-release
CentOS release 6.5 (Final)
[root@localhost ~]# uname -m
x86_64
[root@localhost ~]# uname -r
2.6.32-431.el6.x86_64

配置更新源

cd /etc/yum.repos.d/
curl http://mirrors.163.com/.help/CentOS6-Base-163.repo > CentOS6-Base-163.repo

當前wget還不能用

#wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
mv CentOS-Base.repo CentOS-Base.repo.bak
mv CentOS6-Base-163.repo CentOS-Base.repo
yum makecache

yum -y groupinstall 'base'
yum -y install make

安裝jdk必備軟件包:

yum -y install alsa-lib-devel
yum -y install cups-devel
yum -y install libXi-devel
yum -y install gcc gcc-c++
yum -y install libX*

上傳或下載相關文件到/application/tools

mkdir -p /application/tools
cd /application/tools

上傳或下載下列相關文件到/application/tools

freetype-2.3.12.tar.gz 下載地址：http://sourceforge.net/projects/freetype/files/freetype2/

openjdk-7u6-fcs-src-b24-28_aug_2012.zip 下載地址前文

apache-ant-1.7.1-bin.zip 下載地址：http://archive.apache.org/dist/ant/binaries/　　

jdk-6u26-linux-x64.bin 下載地址：http://www.Oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase6-419409.html#jdk-6u26-oth-JPR

編譯安裝freetype：

tar -xzf freetype-2.3.12.tar.gz
cd freetype-2.3.12
./configure 
make
make install

安裝JDK：

解壓縮jdk-6u26-linux-i586.bin到application/java/目錄下

設置環境變量如下：

#set java environment
JAVA_HOME=/application/java/jdk
export JRE_HOME=/application/java/jdk/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

安裝ant：

cd /application/tools/
unzip apache-ant-1.7.1-bin.zip 
ln -s /application/tools/apache-ant-1.7.1/bin/ant /usr/bin/ant

檢查java與ant：

[root@localhost ~]# java -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)
[root@localhost ~]# ant
Buildfile: build.xml does not exist!
Build failed

3.配置變量

nset CLASSPATH
unset JAVA_HOME
export LANG=C
export ALT_BOOTDIR=/application/java/jdk
export ANT_HOME=/application/tools/apache-ant-1.8.1/
export ALT_FREETYPE_LIB_PATH=/usr/local/lib
export SKIP_DEBUG_BUILD=false
export SKIP_FASTDEBUG_BUILD=true
export DEBUG_NAME=debug
export ALT_FREETYPE_HEADERS_PATH=/usr/local/include/freetype2

4.檢查環境是否配置OK與編譯jdk源碼

[root@localhost tools]# cd openjdk
[root@localhost openjdk]# pwd
/application/tools/openjdk
[root@localhost openjdk]# make sanity

……

OpenJDK-specific settings:
FREETYPE_HEADERS_PATH = /usr/local/include/freetype2
ALT_FREETYPE_HEADERS_PATH = /usr/local/include/freetype2
FREETYPE_LIB_PATH = /usr/local/lib
ALT_FREETYPE_LIB_PATH = /usr/local/lib

Previous JDK Settings:
PREVIOUS_RELEASE_PATH = USING-PREVIOUS_RELEASE_IMAGE
ALT_PREVIOUS_RELEASE_PATH =
PREVIOUS_JDK_VERSION = 1.6.0
ALT_PREVIOUS_JDK_VERSION =
PREVIOUS_JDK_FILE =
ALT_PREVIOUS_JDK_FILE =
PREVIOUS_JRE_FILE =
ALT_PREVIOUS_JRE_FILE =
PREVIOUS_RELEASE_IMAGE = /application/java/jdk
ALT_PREVIOUS_RELEASE_IMAGE =

Sanity check passed.

執行下列命令：

[root@localhost openjdk]# make all
