How to install perf on a custom build kernel?
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.
I installed linux-tools-common, linux-base and linux-tools.
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 linux-tools-3.12.6.
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)?
apt kernel

@Braiam This is a very late comment, but would you mind adding some detail about where to find the source for linux-tools (eg. in the kernel source) and how to compile it? (eg. run make in linux/tools/perf) etc? I'd make for a more complete answer.

You appear to have installed a custom kernel. 3.12 is not in Ubuntu official repositories. This means you'll have to install the tools yourself or to revert the custom kernel installation.
