Linux Install Gcc

Question

I am new to linux and I am setting up a Linux-64 bit for programming in C++ and I want to install the gcc.x86_64 and gcc-C++.x86_64. I use command yum install the two packages. However, half way through the installation, I got no mirror found for the packages. What should I do to install it?

It shows

Error Downloading Packages:
 glibc-common-2.12.1-4.x86_64: failure: glibc-common-2.12.1-4.x86_64.rpm 
 from updates:[Errno 256] No more mirrors to try.
