1.安装gcc
首先到http://vault.centos.org/6.3/os/x86_64/Packages/下载用到的rpm包，包括：ppl-0.10.2-11.el6.x86_64.rpm 、cloog-ppl-0.15.7-1.2.el6.x86_64.rpm 、mpfr-2.4.1-6.el6.x86_64.rpm 、cpp-4.4.6-4.el6.x86_64.rpm 、kernel-headers-2.6.32-279.el6.x86_64.rpm 、glibc-headers-2.12-1.80.el6.x86_64.rpm 、glibc-devel-2.12-1.80.el6.x86_64.rpm 、libstdc++-devel-4.4.6-4.el6.x86_64.rpm 、gcc-4.4.6-4.el6.x86_64.rpm 、gcc-c++-4.4.6-4.el6.x86_64.rpm

即使该包安装成功，后续还是会出现同样的软件依赖包问题
软件包依赖性的问题，用nodeps属性一定能装上
rpm -Uvh *.rpm --nodeps --force
安装完成gcc后可以使用gcc -v查看是否安装成功
同样可以参考：

2.安装expect之前，还需要安装tcl
a.下载源码包
wget http://nchc.dl.sourceforge.net/sourceforge/tcl/tcl8.4.11-src.tar.gz
b.解压缩源码包
tar xfvz tcl8.4.11-src.tar.gz
c.进入/soft/tcl8.4.11/unix 目录
a.执行sed -i "s/relid'/relid/" configure
b.执行./configure --prefix=/expect
c.执行make
d.执行make install
e.执行mkdir -p /tools/lib
f.执行cp tclConfig.sh /tools/lib/
g. 将/tools/bin目录export到环境变量
tclpath=/tools/bin
export tclpath
d.安装expect
进入/soft/expect-5.43目录
执行./configure --prefix=/tools --with-tcl=/tools/lib --with-x=no
如果最后一行提示：
configure: error: Can't find Tcl private headers
需要添加一个头文件目录参数
--with-tclinclude=../tcl8.4.11/generic,即
./configure --prefix=/tools --with-tcl=/tools/lib --with-x=no --with-tclinclude=../tcl8.4.11/generic
../tcl8.4.11/generic 就是tcl解压安装后的路径，一定确保该路径存在
执行make
执行make install
编译完成后会生在/tools/bin内生成expect命令
执行/tools/bin/expect出现expect1.1>提示符说明expect安装成功.
e.创建一个符号链接
ln -s /tools/bin/expect /usr/bin/expect
查看符号连接
ls -l /usr/bin/expect
lrwxrwxrwx 1 root root 17 06-09 11:38 /usr/bin/expect -> /tools/bin/expect
这个符号链接将在编写expect脚本文件时用到，例如在expect文件头部会指定用于执行该脚本的shell
#!/usr/bin/expect
创建符号链接后，可以使用which expect查出expect
