Regarding installation of linux tool "perf" on raspbian

[sarusukh]

I am really struggling with installing linux tool "perf"; (I'm using raspberry pi zero and operating it via my laptop which has windows 10 installed)
My issue is as follows:

When i try to install perf using the following command, it says that its already installed.

sudo apt-get install linux-perf
linux-perf is already the newest version (4.9+80+deb9u4+rpi2).
linux-perf-4.9 set to manually installed.
0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded.


but when i try to run that command, it gives the error as mentioned below:
perf
/usr/bin/perf: line 13: exec: perf_4.19: not found
E: linux-perf-4.19 is not installed.

What version, by name and date, of the Raspbian Operating System are you running on your RPi Zero board?

You need a kernel version specific package for the perf tools to work but it isn't packaged for the Raspberry Pi Trading modified kernel. The repo does have packages for 4.18_4.18.20-2+rpi1_armhf and 5.2_5.2.17-1+rpi1+b2_armhf which are the upstream kernels but they're not used normally in Raspbian.

You need to build it yourself or see if you can appeal to one of the Raspberry Pi engineers to build the missing package for 4.19.
