在XUbuntu 10.10上以JRL源码构建Oracle JDK 6 update 23
上周末在JavaEye问答频道看到这样一个问题：JVM源码编译
sudo aptitude build-dep openjdk-6sudo aptitude install openjdk-6-jdk gcc-4.2 g++-4.2sudo aptitude install libmotif-dev
In addition, it's necessary to set a few environment variables for the build:
export LANG=C ALT_BOOTDIR=/usr/lib/jvm/java-6-openjdk
Then, calling make in the top level OpenJDK source code directory with the following parameters results in a working build:
make all CC=gcc-4.2 CPP=g++-4.2
（注：没有aptitude的话把上面的代码改为用apt-get就行
另外，实际build的时候发觉如果JAXP和JAXWS出问题的话只要再多来个export ALLOW_DOWNLOADS=true就好了。
OpenJDK6 build 20及之前的版本的CORBA要build起来可能有点麻烦，没用到的话直接BUILD_CORBA=false吧。另外现在java.net迁移了之后，这些版本里jaxp.properties和jaxwa.properties里的下载地址不对了，要修正）
在OpenJDK之外，Sun确实也有以别的许可证形式提供JDK的源码。
其中一种是Sun Community Source License (SCSL)。这与微软在公布其.NET的虚拟机CLR的部分实现——SSCLI所使用的许可证有相似之处。Sun从1998年12月开始就通过SCSL许可证公布了许多产品的源码，包括全线JDK源码，一直到JDK 5.0。
SCSL的可操作性一直受到社区的诟病，所以从JDK 5.0开始，Sun开始使用一种新的许可证，Java Research License (JRL)来公布其源码，主要用于面向研究人员提供JDK源码。
由于这两种许可证的使用限制都比较大，并不是真正意义上的“开源”（大写的Open Source），所以在OpenJDK出来之后，以这两种许可证公布的源码已经越来越不受关注。
根据上个月的一则新闻，Retiring JDK Source Code Bundles Under JRL，以后Oracle JDK将不会再以JRL许可证发布源码，只保留以GPLv2+CE许可证发布OpenJDK源码。
更新（2011-02-04）：几天前刚出的JDK6u25 build 01的源码果然就没有继续以JRL许可证
公开发布了。
但既然写了这一帖，肯定还是有人想直接拿JRL许可证公布的Sun JDK源码来build的。就让我们来看看要build出其中的大部分需要怎样的环境，要做哪些事情吧。
参考文档·README: JDK Builds (JDK v6u23 fcs)
·Kelly O'Hair: JDK6 Build Cheat Sheet
·Noniko's Weblog: Solaris - maybe the easiest environment to build JDK （重点在帖后Kelly O'Hair的回复中）
有篇老文虽然没参考上不过还是把链接记下来吧：
Cay Horstmann: Honey, I built the JDK! (on Ubuntu)
另外，同事大仁先前也询问过build JDK的事。他build的是OpenJDK 7，笔记在这里：
Ubuntu10.04下build OpenJDK7 的过程
构建的目标本帖要build出来的内容主要为研究、开发目的服务，而不用于再发布。因此不把整个Sun JDK里的所有源码都build掉，可以避开一下非常麻烦的东西。
要build出来的部分包括：
·功能完整的HotSpot VM（libjvm.so等）
·功能完整的Java核心类库（rt.jar等）
·功能完整的JDK内建工具及其启动程序（j2sdk-image/bin目录里的）
appletviewer javac jhat jstat rmic unpack200apt javadoc jinfo jstatd rmid wsgenextcheck javah jmap keytool rmiregistry wsimportidlj javap jps native2ascii schemagen xjcjar java-rmi.cgi jrunscript orbd serialverjarsigner jconsole jsadebugd pack200 servertooljava jdb jstack policytool tnameserv
·由上述组件构成的JRE、JDK映像
·上述项目的product build及fastdebug build
不包括：
·JAXP
·JAXWS
·浏览器Java插件
·VisualVM
·JDK或JRE的安装包
获取源码要获取Oracle JDK的最新源码，可以在官网Java SE Downloads页面找到“Java SE 6 JDK Source Code”的一栏，点击“Downlaod”链接即可跳转到当前JDK版本的源码下载页。
2012-06更新：这个链接已经无法下载到JRL许可证的JDK 6源码。下面也是。本帖需要下载的包是这两个：
·JDK 6u23 Source under the JRL license
jdk-6u23-fcs-src-b05-jrl-12_nov_2010.jar
·JDK Binaries for Source Build 6u23
jdk-6u23-fcs-bin-b05-jrl-12_nov_2010.jar
（顺带一提，FCS的意思是Final Customer Shipment
build-essentialgawkm4openjdk-6-jdklibasound2-devlibcups2-devlibxrender-devxorg-devxutils-devx11proto-print-dev
一口气用apt-get把它们都装上就好了：
$ sudo apt-get install build-essential gawk m4 openjdk-6-jdk libasound2-dev libcups2-dev libxrender-dev xorg-dev xutils-dev x11proto-print-dev
虽然我没通过apt-get显式安装binutils，但确认了这系统实际上有装过，如果build过程中有意外的错误的话请安装binutils：
$ sudo apt-get install binutils
其中，
build-essential gawk m4 binutils：
这些是Linux上的一些基本工具，build许多东西都需要它们。build-essential主要用来装g++（GNU C++编译器）及C++标准库；gawk是GNU版awk，用来做文本操作；m4是一种模板语言，AWT的DebugHelper依赖它来生成部分源码；binutils主要是链接器、汇编器、反汇编器之类的。
openjdk-6-jdk：
要build JDK，需要先安装一个启动用的JDK（“Bootstrap JDK”）。apt-get默认将它安装在/usr/lib/jvm/java-6-openjdk。build的时候要把ALT_BOOTDIR设置到它的安装目录上。这里装Sun JDK来做Bootstrap JDK也行。
libasound2-dev：
这是Advanced Linux Sound Architecture (ALSA)相关的依赖。
libcups2-dev：
这是Common UNIX Printing System (CUPS)相关的依赖。
libxrender-dev xorg-dev xutils-dev x11proto-print-dev：
这些全部都是X相关的依赖，主要是为了build出AWT的部分才会需要的。这部分依赖非常非常蛋疼。在安装完依赖后，还得造个符号链接，把/usr/lib映射为/usr/X11R6的别名，这样build过程才能正确找到X11的头文件：
$ sudo mkdir /usr/X11R6$ cd /usr/X11R6/$ sudo ln -s -T /usr/lib lib
开始build准备源码在真正开始build之前，先把先前下载到的两个包，jdk-6u23-fcs-src-b05-jrl-12_nov_2010.jar 与 jdk-6u23-fcs-bin-b05-jrl-12_nov_2010.jar 解压到同一目录下，确保该目录有读写权限，并确认该目录有4G以上的剩余空间可用。
本帖中源码包是解压到/media/JDK6_build_area/jdk6u23目录中的。
为了解决一个缺少符号的问题，要在解压出来的源码目录里，找到j2se/src/solaris/native/sun/awt/awt_GraphicsEnv.c，第965行：
if (xerr->minor_code == X_ShmAttach) {将X_ShmAttach改为1，变成：
if (xerr->minor_code == 1) {设置环境变量本帖描述的build过程中需要设置的环境变量只有一个，
$ export LANG=C
如果环境中已经设置了JAVA_HOME的话，要将该环境变量去掉，否做build过程中会有诡异的事情发生：
$ unset JAVA_HOME
检查编译环境的正确性进入到解压后源码包的control/make目录中，用make dev-sanity命令即可。该命令后面要带上一些环境参数，完整如下
$ make dev-sanity BUILD_DEPLOY=false SKIP_COMPARE_IMAGES=true ALT_BOOTDIR=/usr/lib/jvm/java-6-openjdk ALT_DEVTOOLS_PATH=/usr/bin HOTSPOT_BUILD_JOBS=2
检查过程中输出的日志请见本帖附录。简单介绍其中几个参数的含义：
dev（或者DEV_ONLY）：
把它设置为true可以让另外三个变量也变为true：SKIP_COMPARE_IMAGES、BUILD_INSTALL、NO_DOCS。
BUILD_DEPLOY：
把它设置为false可以避开javaws和浏览器Java插件之类的部分的build。
BUILD_INSTALL：
把它设置为false就不会build出安装包。因为安装包里有些奇怪的依赖，但即便不build出它也已经能得到完整的JDK映像，所以还是别build它好了。
SKIP_COMPARE_IMAGES：
比较本次build出来的映像与先前版本的差异。这个对我们来说没有意义，必须设置为false，否则sanity检查会报缺少先前版本JDK的映像。如果有设置dev或者DEV_ONLY=true的话这个不显式设置也行。
ALT_BOOTDIR：
Bootstrap JDK的安装路径。必须设置。
ALT_DEVTOOLS_PATH：
zip和unzip工具所在的路径。必须设置。
HOTSPOT_BUILD_JOBS：
这个变量主要是设置build HotSpot的过程的并发程度。基本上设到跟CPU的核数一样多没什么问题吧。这个参数不设也没关系。
ALT_JDK_IMPORT_PATH：
这个变量不用设置。因为要build的JDK足够完整，缺少的部分我们都不需要。
正式开始build环境设置好之后，剩下就没啥问题了。在解压出来的源码包的control/make目录里连续执行两次下述命令即可。后一次时间会比较长，中间做点什么别的事吧，别傻等哦
$ make dev BUILD_DEPLOY=false SKIP_COMPARE_IMAGES=true ALT_BOOTDIR=/usr/lib/jvm/java-6-openjdk ALT_DEVTOOLS_PATH=/usr/bin HOTSPOT_BUILD_JOBS=2
为什么要连续执行两次呢？反正在本帖的环境里，源码包中所包含的Motif是没办法一次过顺利build出来的。第一执行上面的命令后，会看到类似这样的错误：
gcc: /media/JDK6_build_area/jdk6u23/control/build/linux-i586/motif-i586/lib/libXm.a: No such file or directorymake[4]: *** [/media/JDK6_build_area/jdk6u23/control/build/linux-i586/lib/i386/motif21/libmawt.so] Error 1make[4]: Leaving directory `/media/JDK6_build_area/jdk6u23/j2se/make/sun/motif21'make[3]: *** [all] Error 1make[3]: Leaving directory `/media/JDK6_build_area/jdk6u23/j2se/make/sun'make[2]: *** [all] Error 1make[2]: Leaving directory `/media/JDK6_build_area/jdk6u23/j2se/make'make[1]: *** [j2se-build] Error 2make[1]: Leaving directory `/media/JDK6_build_area/jdk6u23/control/make'make: *** [dev-build] Error 2
但其实没关系，无视它，再执行一次同样的命令，就build过去了。
Build正确完成后，最后应该可以看到类似下面的提示信息：
generic_debug_build build finished: 11-01-16 03:11make[2]: Leaving directory `/media/JDK6_build_area/jdk6u23/control/make'Control workspace build finished: 11-01-16 03:11make[1]: Leaving directory `/media/JDK6_build_area/jdk6u23/control/make'
然后到build出来的JDK映像的bin目录里去看看的话，
rednaxelafx@vbox:/media/JDK6_build_area/jdk6u23/control/make$ cd ../build/linux-i586/j2sdk-image/bin/rednaxelafx@vbox:/media/JDK6_build_area/jdk6u23/control/build/linux-i586/j2sdk-image/bin$ ./java -versionjava version "1.6.0-internal"Java(TM) SE Runtime Environment (build 1.6.0-internal-rednaxelafx_16_jan_2011_02_10-b00)Java HotSpot(TM) Server VM (build 19.0-b09, mixed mode)rednaxelafx@vbox:/media/JDK6_build_area/jdk6u23/control/build/linux-i586/j2sdk-image/bin$ cd ../../j2sdk-debug-image/fastdebug/bin/rednaxelafx@vbox:/media/JDK6_build_area/jdk6u23/control/build/linux-i586/j2sdk-debug-image/fastdebug/bin$ ./java -versionjava version "1.6.0-internal-fastdebug"Java(TM) SE Runtime Environment (build 1.6.0-internal-fastdebug-rednaxelafx_16_jan_2011_02_38-b00)Java HotSpot(TM) Server VM (build 19.0-b09-fastdebug, mixed mode)
到此，我们自己build出来的Sun（-> Oracle） JDK就到手了。然后随便改改代码、调试来玩玩吧
看，build出来的JDK里的JConsole运行也是正常的哦，前面libXm.a的那个错误不是大问题：

2011-08-07追记
刚build了一个最新的hotspot-comp出来，顺便加到这帖里。
源码地址：
要先装上Mercurial来抓源码。然后build之前要确定装了Ant。
下好源码后
chmod +x get_source.sh./get_source.shmake LANG=C ALT_BOOTDIR=/usr/lib/jvm/java-6-openjdk ALT_DEVTOOLS_PATH=/usr/bin SKIP_FASTDEBUG_BUILD=false HOTSPOT_BUILD_JOBS=2
如果jaxp和jaxwa的build出错的话在它们各自的build.properties文件里加上allow.downloads=true
jdk目录build的时候在javadoc上出了点问题，所以把jdk/make/Makefile里的docs整个注释掉了
64-bit: ARCH_DATA_MODEL=64
Charles Nutter's build script: https://gist.github.com/1148321
make -C make ALT_BOOTDIR=~/sdk/jdk1.8.0b49 ALT_SLASH_JAVA=$HOME/java LANG=C HOTSPOT_BUILD_JOBS=4 ARCH_DATA_MODEL=64 all_fastdebug
make sure this symlink is live: ~/java/re/j2se/1.8.0/promoted/latest/binaries/linux-amd64 -> some valid JDK8 installation

你在解压源码JAR的时候一定要有X支持的图形界面，否则它就无法解压。例如说如果你简单的通告ssh连接到远程服务器去做这个解压就会失败，因为那样连接只要字符界面而没有图形界面。No X11 DISPLAY variable was set, but this program performed an operation which requires it.java.awt.HeadlessException: No X11 DISPLAY variable was set, but this program performed an operation which requires it.

貌似有个设置display的，设置了ssh就可以做这样的事了。
看起来像是ad文件里有问题。但实际是什么问题我看不出来…

呵呵 高端装备折磨死我了，谢谢啦O(∩_∩)O~
