centos 7.2 下编译 openjdk

系统环境:centos 7.2 web 服务器版

1. 安装必备依赖

        yum -y groupinstall 'base'

        yum -y install make

        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*

        yum install libstdc++-static 

2.下载软件

    apache-ant-1.9.2-bin.tar.gz 

    freetype-2.4.12.tar.gz  

    jdk-7u79-linux-x64.gz 

    openjdk-7u40-fcs-src-b43-26_aug_2013.zip

3.编译freetype

     解压 tar -zxvf freetype-2.4.12.tar.gz 

     cd freetype-2.4.12

     ./configure

     make 

     make install

4.解压jdk(bootstrap jdk ，编译java文件使用)

    解压 tar -zxvf jdk-7u79-linux-x64.gz  /mnt/jdk7u79

   vim /etc/profile 在文件结尾加入以下四项:

    export JAVA_HOME= /mnt/jdk7u79

    export JRE_HOME /mnt/jdk7u79/jre

    export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH

    export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin

  执行  source /etc/profile 生效

5.安装ant 

    unzip apache-ant-1.9.2 

    ln -s  ./apache-ant-1.9.2/bin/ant /usr/bin/ant

6.处理openjdk源码

解压至openjdk     unzip openjdk-7u40-fcs-src-b43-26_aug_2013.zip

更改时间:

   vim ./openjdk/jdk/src/share/classes/java/util/CurrencyData.properties更改所有时间为十年内时间

   否则编译时会报异常

去除test_gamma

  vim ./openjdk/hotspot/make/linux/MakeFile

  删除其中所有的test_gamma,不然编译会因为这个通不过

7.设置当前环境变量

    unset CLASSPATH

    unset JAVA_HOME

    export

    export ALT_BOOTDIR=/mnt/jdk7u79

    export ANT_HOME=/applications/tools/apache-ant-1.9.2

    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

8.检查编译环境(切换至openjdk目录)

    make sanity

----------

------

Sanity check passed.----

 8.   执行编译

    make all

大功告成

cd  ./openjdk/build/linux-amd64/bin

./java -version
