openjdk6在linux上的编译手顺
openjdk6在linux上的编译手顺
我在xubuntu上编译openjdk6是按照http://rednaxelafx.iteye.com/blog/875957撒加这篇文章编译的，可是仔细琢磨才知道这篇文章是编译sun以jrl许可证发放出来的jdk源码的，不过大体思路差不多，有少许差别(就是这少许区别搞了很久。。。)。
环境：在virtual4.2.4装上xubuntu10.04.2
一开始是按照OpenJDK6 Build README
http://hg.openjdk.java.net/jdk6/jdk6/raw-file/tip/README-builds.html里面的步骤来的，下载并安装gcc，openjdk等。。。这里我的gcc版本为4.3，openjdk版本为6
hg clonehttps://bitbucket.org/pmezard/hgforest-crew/overview/ MyHgForest
默认下载到/etc/MyHgForest目录
然后将命令添加到Mercurial (/etc/mrcurial)的hgrc文件中
[extensions]
forest = YourHgForest/forest.py
用hg命令下载openjdk6
hg fclone http://hg.openjdk.java.net/jdk6/jdk6openjdk6 (openjdk6会下载到当前目录)
然后执行命令(暂时不知道这个有什么作用。。。)
cd openjdk6
sh./make/scripts/hgforest.sh pull –u
然后安装jdk6相关的依赖和用来编译c的gcc等工具
sudo aptitude build-dep openjdk-6
sudo aptitude install openjdk-6-jdk gcc-4.3 g++-4.3 (我这里gcc-4.2安装失败)
sudo aptitude installlibmotif-dev
配置环境变量
export LANG=CALT_BOOTDIR=/usr/lib/jvm/java-1.6.0-openjdk(启动级的jdk，我这里装系统时已自动安装好)
export ALLOW_DOWNLOADS=true(JAXP和JAXWS部分的源码要动态下载)
unset JAVA_HOME
当时是按照撒加那篇文章的编译的，所以也把撒加安装过的相关工具也一并安装了。。。
sudo apt-get install build-essential gawk m4 libasound2-dev libcups2-dev libxrender-dev xorg-dev xutils-dev x11proto-print-dev
sudo apt-get install binutils
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。
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
相关工具和环境变量已经配置好，可以开始编译了
先进行编译检查，在openjdk6目录下，
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
尽量把出现的errors和warning是都解决掉。
最后开始编译
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
一开始编译JAXP部分出现URLConnection异常，应该是下载JAXP的url地址无效了，索性吧jaxp、jaxws、corba部分都删掉，只剩下langtools,hotspot和JDK。
再次编译。。。
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
编译了几十分钟后，又出现了errors，查看日志，hotspot应该编译成功，问题出现的jdk/make/java/redist 文件夹，can’t cd to/NOT-SET/re/openjdk/6/promoted/latest/binaries/linux-i586(好像是这个)，我了个去，就是因为这个问题，搞了几天，不知道是哪个环境变量没设置。。。
google了N多把。。。没有找到相关的信息。。。
终于有一篇文章有提到相关错误。。。
cd 到jdk/make 下，检查编译变量
make-sanity
这时候出现几个warnings和errors，大概是说没有设置ALT_JDK_IMPORT_PATH、ALT_HOTSPOT_IMPORT_PATH、ALT_HOTSPOT_CLIENT_PATH、ALT_HOTSPOT_SERVER_PATH，没有找到相关的.h文件和libjvm.so文件
于是在jdk/make再次make检查
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
ALT_JDK_IMPORT_PATH=/usr/lib/jvm/ java-6-openjdk
ALT_HOTSPOT_IMPORT_PATH==/usr/lib/jvm/ java-6-openjdk
ALT_HOTSPOT_CLIENT_PATH=/usr/lib/jvm/java-6-openjdk/jre/lib/i386/client
ALT_HOTSPOT_SERVER_PATH=/usr/lib/jvm/java-6-openjdk/jre/lib/i386/server
这次warnings和error是都消失了。。。
最后再次编译
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
ALT_JDK_IMPORT_PATH=/usr/lib/jvm/ java-6-openjdk
ALT_HOTSPOT_IMPORT_PATH==/usr/lib/jvm/ java-6-openjdk
ALT_HOTSPOT_CLIENT_PATH=/usr/lib/jvm/java-6-openjdk/jre/lib/i386/client
ALT_HOTSPOT_SERVER_PATH=/usr/lib/jvm/java-6-openjdk/jre/lib/i386/server
过了几十分钟后，jdk目录编译通过了，在cd到openjdk6路径下再整体编译检查一次
make 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
ALT_JDK_IMPORT_PATH=/usr/lib/jvm/ java-6-openjdk
ALT_HOTSPOT_IMPORT_PATH ==/usr/lib/jvm/ java-6-openjdk
ALT_HOTSPOT_CLIENT_PATH=/usr/lib/jvm/java-6-openjdk/jre/lib/i386/client
ALT_HOTSPOT_SERVER_PATH=/usr/lib/jvm/java-6-openjdk/jre/lib/i386/server
又出现了warnings和errors，好像说不用设置ALT_HOTSPOT_IMPORT_PATH。。。这真奇葩，不管了，就把ALT_HOTSPOT_IMPORT_PATH去掉。。。
make 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
ALT_JDK_IMPORT_PATH=/usr/lib/jvm/ java-6-openjdk
ALT_HOTSPOT_CLIENT_PATH=/usr/lib/jvm/java-6-openjdk/jre/lib/i386/client
ALT_HOTSPOT_SERVER_PATH=/usr/lib/jvm/java-6-openjdk/jre/lib/i386/server
这次编译检查通过了，于是开始编译。。。
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
ALT_JDK_IMPORT_PATH=/usr/lib/jvm/ java-6-openjdk
ALT_HOTSPOT_CLIENT_PATH=/usr/lib/jvm/java-6-openjdk/jre/lib/i386/client
ALT_HOTSPOT_SERVER_PATH=/usr/lib/jvm/java-6-openjdk/jre/lib/i386/server
最后编译成功。
build出的hotspot,langtools和jdk都在build/linux-i586/j2sdk-image下
将PATH中的/usr/bin(因为里面有java命令)去掉，将/home/nature/workplace/openjdk6/build/linux-i586/j2sdk-image/bin添加到PATH中
然后测试下 java –version
确定编译成功。。。
最后在openjdk6下make-sanity再看下
