Linux RedHat 安装Oracle11gR2的时候出现以下报错：
RHEL 6.1默认是没有gcc和gcc-c++环境的，总结本地安装方法如下：
上传安装镜像rhel-server-6.1-x86_64-dvd.iso，
然后将镜像文件挂，如/mnt
# mount -o loop rhel-server-6.1-x86_64-dvd.iso /mnt
# cd /mnt/Packages
# rpm -ivh glibc-common-2.12-1.25.el6.x86_64.rpm
# rpm -ivh kernel-headers-2.6.32-131.0.15.el6.x86_64.rpm
# rpm -ivh libgcc-4.4.5-6.el6.x86_64.rpm
# rpm -ivh glibc-2.12-1.25.el6.x86_64.rpm
# rpm -ivh libgomp-4.4.5-6.el6.x86_64.rpm
# rpm -ivh nscd-2.12-1.25.el6.x86_64.rpm
# rpm -ivh glibc-headers-2.12-1.25.el6.x86_64.rpm
# rpm -ivh glibc-devel-2.12-1.25.el6.x86_64.rpm
# rpm -ivh mpfr-2.4.1-6.el6.x86_64.rpm
# rpm -ivh ppl-0.10.2-11.el6.x86_64.rpm
# rpm -ivh cloog-ppl-0.15.7-1.2.el6.x86_64.rpm
# rpm -ivh cpp-4.4.5-6.el6.x86_64.rpm
# rpm -ivh gcc-4.4.5-6.el6.x86_64.rpm
注：以上是安装gcc，软件安装顺序不能错。
******************************************
# rpm -ivh libstdc++-4.4.5-6.el6.x86_64.rpm
# rpm -ivh libstdc++-devel-4.4.5-6.el6.x86_64.rpm
# rpm -ivh gcc-c++-4.4.5-6.el6.x86_64.rpm
注：以上是安装gcc-c++
非常感谢原作者（已经找不到原作者了0.0），尽管我是RedHat5.9的版本，挂载后的rpm包在/mnt/Server目录下，由于rpm包版本不一样，包的名字也要模糊查询下才行，但是根据这个方法还是解决了我的问题。
