getting symbols for libc

[George N. <gn...@cm...>]

Hi all,

I successfully ran oprofile on a piece of code I'm trying to profile, 
and the libc is eating up a lot of cycles and I'd like to know why, but 
it just groups it together and says "(no symbols)"

How is it that I can get symbols for libc?

Thanks!
George
