CentOS 6.5上编译安装OpenJDK7源码

采用开源的OpenJDK版本，获取其源码的方式有两种：

通Mercurial代码版本管理工具从Repository中直接取得源码，但是速度太慢，需要花费数小时
直接下载官方打包好的源码包（推荐）

下载源码openjdk-7u6-fcs-src-b24-28_aug_2012.zip，解压，下载地址如下:http://www.java.net/download/openjdk/jdk7u6/promoted/b24/openjdk-7u6-fcs-src-b24-28_aug_2012.zip本次编译采用的是64位的OS，编译也是64位的JDK，内存至少需要512MB

1.基本流程

（阅读README和README-builds.html）README-builds.html中包含有详细的安装信息，最好能完整的阅读一下。

2.安装基础软件包

我的CentOS6.5安装在vmware10上，安装时使用最小化（Minimal）安装[root@localhost ~]# cat /etc/RedHat-releaseCentOS release 6.5 （Final）[root@localhost ~]# uname -mx86_64[root@localhost ~]# uname -r2.6.32-431.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 当前wget还不能用#wget http://mirrors.163.com/.help/CentOS6-Base-163.repomv CentOS-Base.repo CentOS-Base.repo.bakmv CentOS6-Base-163.repo CentOS-Base.repoyum makecacheyum -y groupinstall "base"yum -y install make安装jdk必备软件包:yum -y install alsa-lib-develyum -y install cups-develyum -y install libXi-develyum -y install gcc gcc-c++yum -y install libX*上传或下载相关文件到/application/toolsmkdir -p /application/toolscd /application/tools上传或下载下列相关文件到/application/toolsfreetype-2.3.12.tar.gz 下载地址：http://sourceforge.net/projects/freetype/files/freetype2/openjdk-7u6-fcs-src-b24-28_aug_2012.zip 下载地址前文apache-ant-1.7.1-bin.zip 下载地址：http://archive.apache.org/dist/ant/binaries/ jdk-6u26-linux-x64.bin 下载地址：http://www.Oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase6-419409.html#jdk-6u26-oth-JPR编译安装freetype：tar -xzf freetype-2.3.12.tar.gzcd freetype-2.3.12./configure makemake install安装JDK：解压缩jdk-6u26-linux-i586.bin到application/java/目录下设置环境变量如下：#set java environmentJAVA_HOME=/application/java/jdkexport JRE_HOME=/application/java/jdk/jreexport CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATHexport PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH安装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检查java与ant：[root@localhost ~]# java -versionjava 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 ~]# antBuildfile: build.xml does not exist！Build failed

3.配置变量

nset CLASSPATHunset JAVA_HOMEexport LANG=Cexport ALT_BOOTDIR=/application/java/jdkexport ANT_HOME=/application/tools/apache-ant-1.8.1/export ALT_FREETYPE_LIB_PATH=/usr/local/libexport SKIP_DEBUG_BUILD=falseexport SKIP_FASTDEBUG_BUILD=trueexport DEBUG_NAME=debugexport ALT_FREETYPE_HEADERS_PATH=/usr/local/include/freetype2

4.检查环境是否配置OK与编译jdk源码

[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:
