[CentOS]安装软件:/lib/ld-linux.so.2: bad ELF interpreter解决
环境:
[orangle@localhost Downloads]$ uname -m&&uname -r
x86_64
2.6.32-220.el6.x86_64
[orangle@localhost Downloads]$ cat /etc/redhat-release
CentOS release 6.2 (Final)
****************************************************************************************
使用的时候出现一个错误
bash: /usr/local/bin/rar: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory
是因为64位系统中安装了32位程序
解决方法:yum install glibc.i686
重新安装以后还有如下类系错误 再继续安装包
error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
再执行命令 yum install libstdc++.so.6

安装libstdc++.so.6时有时候还会缺少依赖,如下

当在CentOS 6.2下执行某些命令时,有缺少共享库的报错:
error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
解决办法:
1、执行命令: yum whatprovides libstdc++.so.6, 然后会提示哪个安装包有这个库文件如下:
[root@localhost ~]# yum whatprovides libstdc++.so.6
Loaded plugins: aliases, changelog, downloadonly, fastestmirror, kabi, presto, refresh-packagekit, security, tmprepo, verify,
              : versionlock
Loading support for CentOS kernel ABI
Loading mirror speeds from cached hostfile
