Yum Install Issue - g++

Question

I am trying to install g++ 4.1.2 (seems gcc 4.1.2 is already installed) in a Redhat Linux 6 machine. When I first tried running gcc-c++-4.1.2 rpm through yum, I get the following dependency issues,
[root#Cham1WS Desktop]# yum install gcc-c++-4.1.2-55.el5.x86_64.rpm

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
So, it seems I need to install libstdc++-devel-4.1.2-55.el5.x86_64.rpm. So I tried installing it and I get the follwoing dependencies,
[root#Cham1WS Desktop]# yum install libstdc++-devel-4.1.2-55.el5.x86_64.rpm

It seems an earlier version of libstdc++ is already installed. Anyways, I tried installing libstdc++-4.1.2-55.el5.x86_64.rpm (not the "devel"), and it says it's already installed.
[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
But if I try to install the "libstdc++-devel-4.1.2-55.el5.x86_64.rpm" I get the ealier dependencies again. It seems the issue is that I have a newer version of libstdc++ is already installed
1) How do I fix this issue?
2) Do I need to uninstall the later version of libstdc++?

It seems like you are using yum the wrong way: You should let yum connect to some repositories, and let him figure out the dependencies.
By the way you are installing el5 packages, that means packages for centos5, not centos6. Try finding similar packages but for centos6, that would be better; try using the epel repository which might help you (take a look here on how to enable it: https://www.tecmint.com/how-to-enable-epel-repository-for-rhel-centos-6-5/)
