今天需要在一台干净的RedHat上快速安装gcc，好能编译一些lib库。登录https://idp.redhat.com/idp/，下载了能找到的最高版本的安装包：cpp-3.2.3-60.x86_64.rpm和gcc-3.2.3-60.x86_64.rpm，安装一气呵成：
[root@localhost nan]# rpm -ivh cpp-3.2.3-60.x86_64.rpm
warning: cpp-3.2.3-60.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID db42a60e: NOKEY

[root@localhost nan]# rpm -ivh gcc-3.2.3-60.x86_64.rpm
warning: gcc-3.2.3-60.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID db42a60e: NOKEY

验证一下：
[root@localhost nan]# gcc -v

gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-60)
尽管版本有点低，最起码现在有个能用的gcc了。如果需要高版本，再用这个gcc编译吧。
