Hi,
I'm struggling to get sprof to run, starting to believe there's a bug
somewhere. I'm posting this here because I didn't find any mention
searching the web and checking two other computers, sprof works under
SUSE 10.0 but fails on another openSUSE 10.2.
I'm running openSUSE 10.2, the output of uname -a:
Linux psi 2.6.18.8-0.5-default #1 SMP Fri Jun 22 12:17:53 UTC 2007 i686
i686 i386 GNU/Linux
When collecting profile info with
LD_PROFILE=libc.so.6 LD_PROFILE_OUTPUT=. ls
and afterwards trying to display the profile with
sprof libc.so.6
returns
sprof: failed to load shared object `libc.so.6': No such file or directory
Investigating with ltrace turns up the following:
ltrace sprof libc.so.6

exit(1
+++ exited (status 1) +++
So somehow, somewhere it seems to destroy the name of the so.
Is this a bug in openSUSE's libc? Shall I post this to the glibc
mailinglist?
Cheers,
Christian
