build sun jdk1.6 源代码

最近为了研究jvm, 尝试build java 源代码。

网上有一些openjdk build教程，但是为了后期测试与应用方便，还是选定sun jdk.

感谢RednaxelaFX 同学的帮助，最终结果如下：

http://hllvm.group.iteye.com/group/topic/27149

1. 虽然jdk1.6 README-builds.html 里说要jdk1.5作为Bootstrap, 其实是要求1.6， 所以要先下载安装sun jdk-6u26-linux-x64.bin
注意这里用opensdk 是不行的，没有javap

2. 环境变量设置如下:
ALT_BOOTDIR=/tmp/jdk1.6.0_26
ALT_DEVTOOLS_PATH=/usr/bin
DEVTOOLS_PATH=/usr/bin
LANG=C

3. 安装cups, 下载并build cups-1.5.0-source.tar.bz2

4. 不知道为什么，下载的jdk1.6源码中少了字体文件，ERROR: Missing ./../src/share/lib/fonts/LucidaTypewriterRegular.ttf. 
       Verify you have downloaded and overlayed on the source area all the binary files. 
不管它了，从现有的jre 里拷过来。

5. make dev-sanity 有一些warning, 先不管。

6. 执行make dev-sanity BUILD_DEPLOY=false SKIP_COMPARE_IMAGES=true ALT_BOOTDIR=/tmp/jdk1.6.0_26 ALT_DEVTOOLS_PATH=/usr/bin HOTSPOT_BUILD_JOBS=2

等着......明天来看结果

偶的新机器真快，20分钟不到就结束了，
和这里一样报错，看来还得来一次：http://rednaxelafx.iteye.com/blog/875957

估计是x11库的问题，检查jdk6_src\motif\lib\Xm\util\Makefile，用到了/usr/X11R6/lib

我的本机是没有这个目录的，从/usr/share 下找到了X11, 拷到/usr/X11R6/lib这里。

再build,还有错：

估计还是X11问题，都怪俺装Centos时以为不会做X11 开发，安装省了许多相关库

经过多次折腾，今天张全部搞定了。
不知道什么原因，下载的src 包里总是少了各样的gif, wav等资源文件。
(需要的同学可以联系我，我都在网上找全的)

另外在amd64位下要改下\jdk6_src\j2se\make\sun\jdbc\Makefile 里$(TEMPDIR)/libodbcinst.so: dummyodbc.c  $(TEMPDIR)
$(CC) -shared -fPIC -o $@ $<
$(TEMPDIR)/libodbc.so: dummyodbc.c $(TEMPDIR) 
$(CC) -shared -fPIC -o $@ $<
