百胜安装问题

Question

我正在尝试在 Redhat Linux 6 机器上安装 g++ 4.1.2（似乎已经安装了 gcc 4.1.2）。当我第一次尝试通过 yum 运行 gcc-c++-4.1.2 rpm 时，出现以下依赖问题，

[root@Cham1WS Desktop]# yum install gcc-c++-4.1.2-55.el5.x86_64.rpm 
Setting up Install Process

Error: Package: gcc-c++-4.1.2-55.el5.x86_64 (/gcc-c++-4.1.2-55.el5.x86_64)

           libstdc++ = 4.4.7-16.el6 
 You could try using --skip-broken to work around the problem 
 You could try running: rpm -Va --nofiles --nodigest 

所以，看来我需要安装 libstdc++-devel-4.1.2-55.el5.x86_64.rpm。所以我尝试安装它，我得到了以下依赖项，

[root@Cham1WS Desktop]# yum install libstdc++-devel-4.1.2-55.el5.x86_64.rpm

           libstdc++ = 4.4.4-15.el6 
           libstdc++ = 4.4.7-16.el6

似乎已经安装了较早版本的 libstdc++。无论如何，我尝试安装 libstdc++-4.1.2-55.el5.x86_64.rpm （不是“devel”），它说它已经安装了。

[root@Cham1WS Desktop]# yum install libstdc++-4.1.2-55.el5.x86_64.rpm 
Setting up Install Process 
Examining libstdc++-4.1.2-55.el5.x86_64.rpm: libstdc++-4.1.2-55.el5.x86_64 
libstdc++-4.1.2-55.el5.x86_64.rpm: does not update installed package. 
Error: Nothing to do

但如果我尝试安装“libstdc++-devel-4.1.2-55.el5.x86_64.rpm”，我会再次获得更早的依赖项。看来问题是我已经安装了更新版本的 libstdc++

1) 我该如何解决这个问题？ 2) 是否需要卸载更高版本的libstdc++？

看来你用错了yum：你应该让yum连接到一些仓库，让他找出依赖关系。

顺便说一下，您安装的是 el5 软件包，这意味着 centos5 的软件包，而不是 centos6 的软件包。尝试寻找类似的软件包，但对于 centos6，那会更好；尝试使用可能对您有所帮助的 epel 存储库（查看如何启用它：https://www.tecmint.com/how-to-enable-epel-repository-for-rhel-centos-6-5/）
