CentOS 6.9 Minimal 编译OpenJDK 7

今天学习《深入理解Java虚拟机：JVM高级特性与最佳实践》一书，并动手在Linux系统上编译OpenJDK 7，初次搞不太顺利，特记录下编译操作细节。

一、前期准备

约定：工具默认安装目录是/usr/local/，若有源码，则源码存放在/usr/local/src/目录下。

1、OpenJDK

下载OpenJDK 7，地址：http://download.java.net/openjdk/jdk7/promoted/b147/openjdk-7-fcs-src-b147-27_jun_2011.zip，文件校验码：http://download.java.net/openjdk/jdk7/promoted/b147/openjdk-7-fcs-src-b147-27_jun_2011.md5

wget http://download.java.net/openjdk/jdk7/promoted/b147/openjdk-7-fcs-src-b147-27_jun_2011.zip 　　# 下载

unzip openjdk-7-fcs-src-b147-27_jun_2011.zip 　　# 解压

mv openjdk openjdk7　　# 更改目录名

2、FreeType

笔者使用的是freetype-2.4.0.tar.gz，下载地址：https://sourceforge.net/projects/freetype/files/freetype2/2.4.0/

tar -zxvf freetype-2.4.0.tar.gz  　　# 解压

cd freetype-2.4.0

./configure && make && make install  　　# 编译安装

3、Apache Ant

笔者使用的是apache-ant-1.9.7-bin.tar.gz，下载地址：https://archive.apache.org/dist/ant/binaries/

tar -zxvf apache-ant-1.9.7-bin.tar.gz　　# 解压

mv apache-ant-1.9.7 /usr/local/

ln -s /usr/local/apache-ant-1.9.7/bin/ant  /usr/bin/ant　　# 软链接到bin

4、BootstrapJDK

笔者使用的是jdk-6u45-linux-x64，因为源码更多是使用Java写的，因此需要使用一个可用的JDK去编译（详见深入理解Java虚拟机第一章），OpenJDK解压目录下有个README-builds.html<OpenJDK Build README>，建议详看一遍，文档说使用JDK 6

下载jdk-6u45-linux-x64.bin，下载地址：http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase6-419409.html

./jdk-6u45-linux-x64.bin  　　# 解压

mv jdk1.6.0_45 /usr/local/　　# 移动目录

5、编译需要的相关工具

yum -y install gcc gcc-c++ alsa-lib alsa-lib-devel libXrender libXrender-devel libXi-devel libXt-devel libXtst-devel cups cups-devel

二、配置环境变量

vim /etc/profile　　# 在末尾加入以下内容注意各个目录Path

# openjdk 7 build
export ANT_HOME=/usr/local/apache-ant-1.9.7
export ALT_FREETYPE_HEADERS_PATH=/usr/local/include/freetype2
export ALT_FREETYPE_LIB_PATH=/usr/local/lib
export ALT_DROPS_DIR=/usr/local/src/openjdk7/drop
export ALT_BOOTDIR=/usr/local/jdk1.6.0_45
export ALT_JDK_IMPORT_PATH=/usr/local/jdk1.6.0_45
export ALT_OUTPUTDIR=/usr/local/openjdk7
export LANG=C
export HOTSPOT_BUILD_JOBS=8
export ALT_PARALLEL_COMPILE_JOBS=8
export SKIP_COMPARE_IMAGES=true
export USE_PRECOMPILED_HEADER=true
export ALLOW_DOWNLOADS=true
export SKIP_DEBUG_BUILD=false
export SKIP_FASTDEBUG_BUILD=true
export DEBUG_NAME=debug
unset JAVA_HOME
unset CLASSPATH

　　:wq　　# 写入磁盘

　　source /etc/profile　　# 刷新环境变量配置使之生效，建议echo下几个配置项确认生效，例：echo $LANG

　　cd openjdk7　　# 进入OpenJDK解压目录

　　make sanity　　　# 检查之前的配置是否正确，若无错误（Sanity check passed.）则OK，下面是笔者的执行结果宫参考

[root@dsp-centos-3-6_9 openjdk7]# make sanity

三、编译操作

 　　make 2>&1 | tee $ALT_OUTPUTDIR/build.log　　# 编译，标准错误输出stderr重定向到标准输出stdout，将编译过程数据重定向到文件保存。

　　若编译失败，重新编译前先执行：make clean

　　若编译成功，提示信息如下：

-- Build times ----------
Target debug_build
Start 2018-04-30 23:30:30
End 2018-04-30 23:45:05
00:01:45 corba
00:03:32 hotspot
00:00:18 jaxp
00:00:24 jaxws
00:08:05 jdk
00:00:31 langtools
00:14:35 TOTAL
-------------------------

四、验证

　　进入/usr/local/openjdk7/bin（即$ALT_OUTPUTDIR/bin）目录，执行：./java -version

[root@dsp-centos-2-6_9 bin]# ./java -version
openjdk version "1.7.0-internal-debug"
OpenJDK Runtime Environment (build 1.7.0-internal-debug-root_2018_04_30_20_26-b00)
OpenJDK 64-Bit Server VM (build 21.0-b17-jvmg, mixed mode)

五、笔者碰到的问题

　　1、java.lang.RuntimeException: time is more than 10 years from present

　　　　修改jdk/src/share/classes/java/util/CurrencyData.properties，将日期改为十年以内，JDK的Bug。

　　108行改为： AZ=AZM;2009-12-31-20-00-00;AZN，接下来的377、439、529、555行类似修改保存，重新编译。

2、/usr/local/openjdk7-debug/jaxws/build/xml_generated/build-drop-jaf_src.xml:96: Redirection detected from https to http. Protocol switch unsafe, not allowed.

　　原因是jdk7-jaf-2010_08_19.zip这个包下载不了导致的，解决方案：

将以下三个文件下载后置于OpenJDK解压后根目录下的drop目录下，并在环境变量中加入配置：export ALT_DROPS_DIR=/usr/local/src/openjdk7/drop # 注意目录Path
