No samples

[Martin M. <ma...@si...>]

Hi,

I've compiled oprofile 0.9.7 from source and tried to run it, but get the
dreaded:

error: no sample files found: profile specification too strict ?

Here's how I start it:

    sudo opcontrol --reset
    sudo opcontrol --shutdown
    sudo opcontrol --deinit
    sudo opcontorl --init
    sudo opcontrol --no-vmlinux
    sudo opcontrol --start-daemon
    sudo opcontrol --start

Then I run my command, a CPU intensive task that takes 1 second.

Then I do:

sudo opcontrol --stop
sudo opcontrol --dump
opreport --symbols

ls -l /var/lib/oprofile/samples/
total 12
drwxr-xr-x 3 root root 4096 Jul 10 13:31 current
-rw-r--r-- 1 root root 5244 Jul 10 13:32 oprofiled.log

Note: I'm doing this on a virtual machine running Ubuntu 12.04.

What should I try next?

Thanks,
Martin
