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：

In Linux64/x86-64 environments:

[b]安装[/b]
[code="java"]# tar jxf gcc-4.2.0.tar.bz2
# mkdir /usr/gcc4
# cd /gcc-4.2.0
#./configure --prefix=/usr/gcc4
# make //so long a time
# make install
# which gcc //查看旧版本gcc安装路径
/usr/bin/gcc[/code]
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
[code="java"]# cd /usr/lib
# mv gcc gcc_bak
# mv g++ g++_bak
# mv gcj gcj_bak
# ln -sv /usr/gcc4/bin/gcc gcc
# ln -sv /usr/gcc4/bin/g++ g++
# ln -sv /usr/gcc4/bin/gcj gcj[/code]
此时已经安装成功
[code="java"]# gcc -v
gcc 版本 4.2.0[/code]

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
