I want to use profiling tools in linux. I see some information say Oprofile is not support in Ubuntu 12.04 and the alternate is perf. So I try to install perf.
Then I type
perf in the terminal and it returns:
perf not found for kernel 3.12.6 You may need to install linux-tools-3.12.6-3.12.6
But I could not install either
linux-tools-3.12.6-3.12.6 (I think it's a wrong name) or
Is it a wrong way to install and use perf in that way, or is it the kernel problem(the kernel is compiled by myself)?
