No matter how I try, I can't seem to get a library profile from sprof on
CentOS5.
Does anyone know if sprof actually works on CentOS5? I'd be very
interested to hear if anyone is using it successfully.
At the moment I'm trying something like this to get the dump:
LD_LIBRARY_PATH=. LD_PROFILE=libmy.so ./mymain
where libmy.so is the library I want to profile, and mymain is the
executable which links to it.
This appears to create the profile dump successfully (which appears at
/var/tmp/libmy.so.profile), but when I try to get a readable profile
using sprof it fails:
$ sprof libmy.so /var/tmp/libmy.so.profile
sprof: failed to load shared object `libmy.so'
I have a CentOS4 machine here, and doing the above on that works fine,
but I've had no luck at all on CentOS5 (all currently up-to-date).
Can anyone help? (Please!)
