glibc & me

[justwes]

I'm looking to install Mersenne Prime Search and in their download section they state:

Download mprime235.tar.gz(417K), or the staticly linked sprime235.tar.gz(607K) for systems that do not have the glibc 2.1 runtime libraries.

I'm not sure what glibc is or why I need it, but in my searching I have found it's important to some of the programs.

What I need to know is how to I verify my version?

I tired one command and got the following

[wes@localhost wes]$ rpm -qa | grep glibc
glibc-utils-2.3.2-101
glibc-2.3.2-101
glibc-devel-2.3.2-101
glibc-profile-2.3.2-101
glibc-common-2.3.2-101
glibc-headers-2.3.2-101
glibc-debug-2.3.2-101
glibc-kernheaders-2.4-8.36
[wes@localhost wes]$

I'm assuming that since all the version numbers are higher than the version in the above quote I'm safe, but I'm wanting to make sure that I'm thinking in the right direction.

Yes, you are thinking correctly.

And glibc is the GNU C library collection.
