A:
From the emails found here and here, I've extracted the following notes:
Given an application my_app', which links against a shared object my_sobj', and has been compiled with the '-g' compile flag:
#set the environment variable LD_PROFILE to the name of the shared obj
export LD_PROFILE=my_obj
#run your application
my_app
#this should create a file /var/tmp/my_sobj.profile
#now run sprof
sprof my_sobj my_sobj.profile
This gives profile information for the shared library, not for my_app

does this only work for libc stuff? Or can I use it on my own compiled shared libraries?

"no PLTREL found in object" is the error I get when trying to profile my own library. What do I need to do at compile/link time to include the required information?
