運行程序時遇到找不到libstdc++.so.6問題原因： 
系統(tǒng)是64bit，該庫是32bit的，在64bit系統(tǒng)上安裝32bit庫

解決辦法：

1. 查看哪個安裝包包含該庫：yum provides libstdc++.so.6

libstdc++-4.4.7-4.el6.i686

2. 安裝 libstdc++-4.4.7-4.el6.i686

yum install  libstdc++-4.4.7-4.el6.i686

報錯： 
–> Finished Dependency Resolution 
Error: Protected multilib versions: libstdc++-4.4.7-4.el6.i686 != libstdc++-4.4.7-3.el6.x86_64 
You could try using –skip-broken to work around the problem 
You could try running: rpm -Va –nofiles –nodigest 
…. 
解決辦法： 
yum update libstdc++-4.4.7-3.el6.x86_64 
然后再執(zhí)行yum install libstdc++-4.4.7-4.el6.i686
