GCC 下载地址与编译安装

安装Oracle webgate11g时需要gcc，在OTN上没有相应的下载，需要自己下载，从这儿知道需要的版本为：

安装

[root@localhost ~]# tar jxf gcc-4.2.0.tar.bz2
[root@localhost ~]# mkdir /usr/gcc4
[root@localhost ~]# cd /gcc-4.2.0
[root@localhost gcc-4.2.0]#./configure --prefix=/usr/gcc4
[root@localhost gcc-4.2.0]# make //so long a time
[root@localhost gcc-4.2.0]# make install
[root@localhost bin]# which gcc  //查看旧版本gcc安装路径
/usr/bin/gcc

分别用新安装的/usr/gcc4/lib/下的gcc、g++、gcj指向替换相应旧的文件夹/usr/lib文件

[root@localhost ~]# cd /usr/lib
[root@localhost bin]# mv gcc gcc_bak
[root@localhost bin]# mv g++ g++_bak
[root@localhost bin]# mv gcj gcj_bak
[root@localhost bin]# ln -sv /usr/gcc4/bin/gcc gcc
[root@localhost bin]# ln -sv /usr/gcc4/bin/g++ g++
[root@localhost bin]# ln -sv /usr/gcc4/bin/gcj gcj

此时已经安装成功

[root@localhost bin]# gcc -v
gcc 版本 4.2.0

问题
1.java/parse-scan.h 找不到此文件
解决办法，安装biso,建议最好是rpm即可.
附件是2.3-2.1版本
