有关SUN jdk编译，欢迎大家讨论

资料1： http://download.java.net/jdk6/6u3/pr...ME-builds.html
以上是 sun官方的编译指南。

我之前的一个讨论帖子：
资料2： http://www.linuxsir.org/bbs/thread337713.html

资料1中提到：
All JDK builds require access to the previously released JDK 5.0, this is often called a bootstrap JDK. The JDK 5.0 binaries can be downloaded from Sun's JDK 5.0 download site. For build performance reasons is very important that this JDK be made available on the local disk of the machine doing the build. You should always set ALT_BOOTDIR to point to the location of the bootstrap JDK installation, this is the directory pathname that contains a bin, lib, and include It's also a good idea to also place its bin directory in the PATH environment variable, although it's not required.

即对jdk6的编译需要用到 jdk5, 我从http://java.sun.com/j2se/1.5.0/download.html
下载了java_ee_sdk-5_01-linux.bin，
但是安装不了。。。
出错信息如下所示:
[root@~]#./java_ee_sdk-5_01-linux.bin
./java_ee_sdk-5_01-linux.bin: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

我知道是共享库的问题。
我机上的是libstdc++.so.6，版本太高的。。。
如下可知，我机上的版本是libstdc++.so.6
ls /usr/lib/libstdc++.*
/usr/lib/libstdc++.a /usr/lib/libstdc++.so /usr/lib/libstdc++.so.6.0.8
/usr/lib/libstdc++.la /usr/lib/libstdc++.so.6

这样的话，java_ee_sdk-5_01-linux.bin用啥办法能装到我机子上呢？

做个连接，让 so.6 与so.5 相同，试一下看看。

编译gcc3

ln -s libstdc++.so.6.0.8 libstdc++.so.5
[root@/usr/lib]#ls libstdc++.* -l
-rw-r--r-- 1 root root 7737944 2008-11-07 09:41 libstdc++.a
-rwxr-xr-x 1 root root 944 2008-11-07 09:41 libstdc++.la

安装失败，这样做不行

gcc --version

关键我机子上现在整套工具链都是 用4.1.2 gcc编译的啊，
你的意思是，我把整个工具链改为 用gcc3.0编译？

no 编译gcc3再把libstdc++.so.5复制过去

这方面 BLFS 手册里有说明的，可是楼主已脱离了 BLFS

你的意思是，系统同时存在两套库吗?
一套3.0的，一套4.1的？

gcc 可以多版共存，俺系统里就有 gcc-4.2.4，gcc-4.3.2，gcc-4.4-20081114 等，呵呵

如果是 openjdk 自己编译一下还好，但 sun jdk 直接用二进制版本好了。
