I need these 2 packages installed on RHEL 6 linux system. They are required by several other programs. When I do: sudo yum install glibc-devel this is output: Loaded plugins: product-id, security Setting up Install Process Package glibc-devel-2.12-1.166.el6_7.1.x86_64 already installed and latest version Nothing to do Is there some EPEL with GLIBC_2.15 for RHEL? If not - what is a workaround here?
