本机环境如下:

[henry@henry-ubuntu:~/program/java/oracle_jdk/jdk1.7.0_51]$ java -version
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) Client VM (build 24.51-b03, mixed mode)

[henry@henry-ubuntu:~/workspace/openjdk/openjdk-7u40-fcs-src-b43-26_aug_2013/openjdk]$ uname -a
Linux henry-ubuntu 3.2.0-29-generic-pae #46-Ubuntu SMP Fri Jul 27 17:25:43 UTC 2012 i686 i686 i386 GNU/Linux

默认全部编译

主要参考文档:README-builds.html,在源代码目录就有。

过程:

  1. 安装mercurial

  2. 下载某个repository(repository与project的区别,参见http://openjdk.java.net/guide/repositories.html

  3. 执行脚本get_source.sh以获取源代码。

  4. 设置基本环境变量。

    export LANG=C 
    export ALT_BOOTDIR=$JAVA_HOME 
    export JAVA_HOME= 
    export CLASSPATH=
    
  5. 相关依赖库

    5.1 安装CUPs,如果安装的时候制定了自定义目录,则还需要配置环境变量ALT_CUPS_HEADERS_PATH

    sudo apt-get install cups-common
    sudo apt-get install libcups2-dev
    

    5.2 安装FreeType,需要2.3以上的版本。如果安装的时候制定了自定义目录,则还需要配置环境变量ALT_FREETYPE_LIB_PATHALT_FREETYPE_HEADERS_PATH

    sudo apt-get install libfreetype6
    sudo apt-get install libfreetype6-dev
    

    5.3 安装ALSA,这个就不要自定义安装了

    sudo apt-get alsa-base
    sudo apt-get alsa-utils
    sudo apt-get install libclalsadrv2
    sudo apt-get install libclalsadrv-dev
    
  6. 至此make sanity应该可以通过了,然后make。

  7. make时的错误

    • 找不到gawk

        sudo apt-get install gawk
      
    • 找不到X11库,执行

        sudo apt-get install libx11-dev 
      
    • fatal error: X11/extensions/shape.h: No such file or directory,执行

        sudo apt-get install libxext-dev
      
    • fatal error: X11/extensions/Xrender.h: No such file or directory,执行

        sudo apt-get install libxrender-dev
      
    • fatal error: X11/extensions/XTest.h: No such file or directory,执行

        sudo apt-get install libxtst-dev
      
    • fatal error: X11/Intrinsic.h: No such file or directory,执行

        sudo apt-get install libxt-dev
      

    如果还有缺少库的情况,可以到这里http://packages.ubuntu.com/搜索。

  8. 继续make时的错误

    • 权限错误

        /home/henry/program/java/oracle_jdk/jdk1.7.0_51/bin/javac -g -encoding ascii -source 6 -target 6 -classpath /home/henry/program/java/oracle_jdk/jdk1.7.0_51/lib/tools.jar -sourcepath /media/sf_win7_e_drive/workspace/openjdk/openjdk-7u6-fcs-src-b24-28_aug_2012/openjdk/hotspot/agent/src/share/classes -d /media/sf_win7_e_drive/workspace/openjdk/openjdk-7u6-fcs-src-b24-28_aug_2012/openjdk/build/linux-i586/hotspot/outputdir/linux_i486_compiler2/product/../generated/saclasses @/media/sf_win7_e_drive/workspace/openjdk/openjdk-7u6-fcs-src-b24-28_aug_2012/openjdk/build/linux-i586/hotspot/outputdir/linux_i486_compiler2/product/../generated/agent.classes.list
              
        warning: [options] bootstrap class path not set in conjunction with -source 1.6
        /media/sf_win7_e_drive/workspace/openjdk/openjdk-7u6-fcs-src-b24-28_aug_2012/openjdk/hotspot/agent/src/share/classes/sun/jvm/hotspot/debugger/win32/coff/COFFFileParser.java:333: error: error while writing COFFFileParser.COFFFileImpl.COFFHeaderImpl.OptionalHeaderWindowsSpecificFieldsImpl: /media/sf_win7_e_drive/workspace/openjdk/openjdk-7u6-fcs-src-b24-28_aug_2012/openjdk/build/linux-i586/hotspot/outputdir/linux_i486_compiler2/product/../generated/saclasses/sun/jvm/hotspot/debugger/win32/coff/COFFFileParser$COFFFileImpl$COFFHeaderImpl$OptionalHeaderWindowsSpecificFieldsImpl.class (Operation not permitted)

        Note: Some input files use unchecked or unsafe operations.
        Note: Recompile with -Xlint:unchecked for details.
      

      没找到具体原因,猜测是与使用了virtualbox,并将编译编译结果输出到windows的共享目录相关。

      变通方法,设置ALT_OUTPUTDIR变量,将编译结果输出到virtualbox的虚拟硬盘中,重新make。

    • 找不到类

        cd linux_i486_compiler2/product && ./test_gamma
        Using java runtime at: /home/henry/program/java/oracle_jdk/jdk1.7.0_51/jre
        Error occurred during initialization of VM
        java/lang/NoClassDefFoundError: java/lang/invoke/AdapterMethodHandle
      

      在classpath中确实没找到AdapterMethodHandle这个类,从下面两个邮件列表中的问题看,应该是新旧两个虚拟机不兼容,所以重新下载源码(openjdk-7u40-fcs-src-b43-26_aug_2013)再编译

  9. make成功

    32bit

    电脑矬真是苦逼,时间长的令人发指。

  10. 运行一下
