在一Linux服务器上检查是否安装了一些包时，遇到老是提示”package compat-libstdc++ is not installed”

但是使用上面命令发现这个这些包其实是已经安装了的，那么为什么老是提示compat-libstdc++没有安装呢？这个是因为使用rpm查询时，包名不正确所致。它真正的报名为 compat-libstdc++-33 而不是compat-libstdc++ 。如果包名正确，那么查询结果就会不一样，如下所示：
[[email protected] ~]# rpm -q --qf '%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})/n' compat-libstdc++-33
compat-libstdc++-33-3.2.3-61 (x86_64)
compat-libstdc++-33-3.2.3-61 (i386)
