Installing gcc on rhel 6.1

Question

GCC doesnt seem to be installed on my Rhel 6.1 machine. Also, when i did:

sudo yum install gcc 

It barfed:

Updating Red Hat repositories.
Setting up Install Process
No package gcc available.
Error: Nothing to do

The same command works fine on rhel 5.5. What could be the problem?

sudo yum search gcc

Returns:

libgcc.x86_64 : GCC version 4.4 shared support library
libgomp.x86_64 : GCC OpenMP v3.0 shared support library

sudo yum grouplist

Returns:

Loaded plugins: product-id, subscription-manager
Updating Red Hat repositories.
Setting up Group Process
Error: No group data available for configured repositories


sudo yum repolist

Returns:

Loaded plugins: product-id, subscription-manager
Updating Red Hat repositories.
repolist: 0

Update:

ls -l /etc/yum.repos.d/

Returns:

-rw-r--r--. 1 root root  67 Nov 28 06:28 redhat.repo
-rw-r--r--. 1 root root 529 Apr 27  2011 rhel-source.repo

Answer 1

yum install gcc should work, as you suspect. Maybe you need to subscribe to a specific channel in RHN but this gcc advisory seems to indicate that gcc should be available on all of these channels, and I assume you're already subscribe to at least one of them:

• Red Hat Enterprise Linux Desktop (v. 6)
• Red Hat Enterprise Linux HPC Node (v. 6)
• Red Hat Enterprise Linux Server (v. 6)
• Red Hat Enterprise Linux Workstation (v. 6)
