Re: profile system API performance

[Lin George <george4academic at yahoo dot com>]

Sorry for typo of your name, Nick!


Actually, I have read through the web site (http://www.gnu.org/software/libc) for major items before asking this question, but there are no document for how to rebuild a libc and no related mail list. Have you found them from the web site?

I have found many useful information from "glibc-profile" search, for example,

http://rpmfind.net/linux/rpm2html/search.php?query=glibc-profile

My challenge is, I need to profile application on various Linux machines, and for some Linux machine, I do not know the distribution name and I only know the architecture, for example, x86-32, Power PC, etc. Any ideas of which glibc-profile should I try? Why the glibc-profile are vendor dependent?


regards,
George

Hi George

Oh yes, this is not for the faint-hearted.

Have you checked out the glibc web site ?

   http://www.gnu.org/software/libc

> BTW: are there any libc which is already enabled with gprof functions (with -pg profile capability) to steal?

That depends upon the Linux distribution that you are using.  I would 
suggest that you check with their web sites.  You could also google for 
"glibc-profile".

Cheers
