Re: Help in removing Oprofile

Hi William,

Also, I have built Oprofile as part of rootfs. My linux version is 2.6.38,
but Oprofile is not running on my target machine.

I see the following :
modprobe: chdir(/lib/modules): No such file or directory
Kernel doesn't support oprofile

I have enabled CONFIG_OPROFILE as part of .config, downloaded and built
popt/, binutils/ and Oprofile. Built went successfully but opcontrol is not
working. Can you please help what I am doing wrong.

Thanks,
Shiva
