Re: Help in removing Oprofile

Hi Will,

I am using Oprofile 0.9.9.  I tried with Oprofile-1.0.0 but later I found
kernel CPU counters were not supported. Shall I try with Oprofile-0.9.7?. I
did following to build Oprofile

Oprofile-0.9.9>./configure --enable-static  --with-kernel-support
 --prefix=/home/shiva/usr
    sudo make
    make install
    DESTDIR="/home/shiva/user"


Thanks,
Shiva
