I need to install below packages:

gcc: gcc-c++-4.4.7-3.el6.x86_64
Flex: flex-2.5.35-8.el6.x86_64
Bison: bison-2.4.1-5.el6.x86_64
Glib: glib2-devel-2.22.5-7.el6.x86_64 & glibc-devel-2.12-1.107.el6_4.2.x86_64
Pcre: pcre-7.8-6.el6.x86_64 & pcre-devel-7.8-6.el6.x86_64
logrotate: logrotate-3.7.8-16.el6.x86_64
sendmail: sendmail-8.14.4-8.el6.x86_64 & sendmail-cf-8.14.4-8.el6.noarch

using yum from below repositories.

# yum repolist

But, I get below error:

# yum install gcc-c++-4.4.7-3.el6.x86_64

No package gcc-c++-4.4.7-3.el6.x86_64 available.
Error: Nothing to do

How to resolve this error? Do I need to add some more repositories? if yes, how?

If you are looking to install GCC, all you need to do is yum install gcc-c++ it will get its dependencies if you have access to them, or it will error out. For the rest of your packages, just put in the text name before <name>-<version number>. yum install flex bison sendmail just see if the other packages get installed as dependencies, if not go back and install them too using yum install <name>.

If you need more help to understand yum, just type man yum for more references and details about yum.
