Re: Error cross compiling oprofile

Thanks Andrew,

That allowed me to compile.  When I try to run operf or ocount on my target
I got an error:

root@dm816x-evm:~# operf
Unexpected error running operf: Invalid argument
root@dm816x-evm:~#

I need to go back and do some cleaning.  I may have some libraries left
over from installing oprofile 0.9.8, although I think I would have seen
some sort of library version mismatch error.

For the moment, my boss is looking for me to find out where all our cycles
have gone missing, and oprofile 0.9.8 using opcontrol seems to be working,
so I will come back to this issue in a few days after the fire is out.

Thanks for your help.
