IIRC, you need to tell oprofile that you are going to use 2.4.x kernel. Check "./configure --help" output of oprofile and see if you can find one. Another thing is, since oprofile is not included by default on 2.4.x kernel, maybe you need to download a kernel patch to create the driver interface for your 2.4.x kernel. Check on OProfile web site for this patch regards Mulyadi -- Kernelnewbies: Help each other learn about the Linux kernel.
