CentOS编译OpenJDK

编译

1. 在编译JDK7之前，安装一个JDK6版本，因为有一些JAVA文件需要编译；
2. 配置更新源，yum -y groupinstall 'base'，yum -y install make；
3. 安装软件包，yum -y install alsa-lib-devel cups-devel libXi-devel gcc gcc-c++ freetype ld-linux.so.2 ant* libX* freetype*
4. 配置环境变量，

   unset CLASSPATH
   unset JAVA_HOME
   export LANG=C
   export SKIP_DEBUG_BUILD=false 
   export SKIP_FASTDEBUG_BUILD=true 
   export DEBUG_NAME=debug 
   export ALT_BOOTDIR=/usr/java/jdk1.6.0_45
   

5. 下载源码、减压缩、验证配置，显示Sanity check passed.  #表示ok了

   wget http://download.java.net/openjdk/jdk7u40/promoted/b43/openjdk-7u40-fcs-src-b43-26_aug_2013.zip?q=download/openjdk/jdk7u40/promoted/b43/openjdk-7u40-fcs-src-b43-26_aug_2013.zip
   unzip openjdk-7u40-fcs-src-b43-26_aug_2013.zip
   cd openjdk
   make sanity

6. 执行编译命令

   make all ARCH_DATA_MODEL=64 ALLOW_DOWNLOADS=tru

7. 检查编译结果

    ./build/linux-amd64/bin/java -version
