备注：已将以上资源打包上传到CSDN:https://download.csdn.net/download/szstudy/10712108

四、编译安装配置环境

1.编译安装freetype：

[root@localhost tools]#tar -xzf freetype-2.3.12.tar.gz
[root@localhost tools]# cd freetype-2.3.12
[root@localhost freetype-2.3.12]#./configure 
[root@localhost freetype-2.3.12]#make
[root@localhost freetype-2.3.12]#make install

2.安装JDK：

[root@localhost java]#chmod a+x jdk-6u45-linux-x64.bin

[root@localhost java]#./jdk-6u45-linux-x64.bin

配置环境变量（配置文件/etc/profile）

JAVA_HOME=/mnt/application/java/jdk1.6.0_45
export JRE_HOME=mnt/application/java/jdk1.6.0_45/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

使环境变量生效：

 [root@localhost etc]#source profile

验证：

[root@localhost openjdk]# java -version
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)

3.安装ant:

[root@localhost tools]#unzip apache-ant-1.9.13-bin.zip 
[root@localhost tools]#ln -s /mnt/application/tools/apache-ant-1.9.13/bin/ant /usr/bin/ant

验证：

[root@localhost tools]#ant
Buildfile: build.xml does not exist!
Build failed

4.配置环境变量（配置文件/etc/profile）

nset CLASSPATH
unset JAVA_HOME
export LANG=C
export ALT_BOOTDIR=/mnt/application/java/jdk1.6.0_45
export ANT_HOME=/mnt/application/tools/apache-ant-1.9.13/
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

使环境变量生效：

 [root@localhost etc]#source profile

5.修改/mnt/application/tool/openjdk/jdk/src/share/classes/java/util/CurrencyData.properties

修改108行
AZ=AZM;2009-12-31-20-00-00;AZN
修改381行
MZ=MZM;2009-06-30-22-00-00;MZN
修改443行
RO=ROL;2009-06-30-21-00-00;RON
修改535行
TR=TRL;2009-12-31-22-00-00;TRY
修改561行
VE=VEB;2009-01-01-04-00-00;VEF

6.检查环境

[root@localhost openjdk]# make sanity
....
....
....
....
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 = /mnt/application/java/jdk1.6.0_45
    ALT_PREVIOUS_RELEASE_IMAGE = 


Sanity check passed.

7.编译

[root@localhost openjdk]# make all
Build times ----------
Target debug_build
Start 2015-05-05 09:34:37
End 2015-05-05 10:24:33
00:05:23 corba
00:10:49 hotspot
00:00:55 jaxp
00:01:07 jaxws
00:30:05 jdk
00:01:36 langtools
00:49:56 TOTAL
-------------------------
make[1]: Leaving directory `/application/tools/openjdk'

8.查看是否编译成功

[root@localhost openjdk]#  ./build/linux-amd64/bin/java -version
openjdk version "1.7.0-internal-debug"
OpenJDK Runtime Environment (build 1.7.0-internal-debug-root_2018_10_10_18_56-b00)
OpenJDK 64-Bit Server VM (build 23.2-b09-jvmg, mixed mode)
