I get a build error on Ubuntu22.04
configure: error: libtracefs is required but was not found

apt install -y libtracefs1
returns already installed

You are right. But it is already installed as well.

apt install -y libtracefs-dev

This fix for me

git clone https://git.kernel.org/pub/scm/libs/libtrace/libtraceevent.git/
cd libtraceevent; make; sudo make install; cd ..;

git clone https://git.kernel.org/pub/scm/libs/libtrace/libtracefs.git/
cd libtracefs; make; sudo make install; cd ..;

Same problem

configure: error: libtracefs is required but was not found

I have installed libtracefs-dev and libtracefs1 in my system

I had to install libtracefs1, libtracefs-dev, libtraceevent1 and libtraceevent-dev. The former two were insufficient on their own.

However, this still resulted in a built error:

devices/i915-gpu.cpp: In function ‘void create_i915_gpu()’:
devices/i915-gpu.cpp:83:14: error: ‘tracefs_event_file_exists’ was not declared in this scope; did you mean ‘tracefs_file_exists’?
   83 |         if (!tracefs_event_file_exists(NULL, "i915", "i915_gem_ring_dispatch", "format")) {
      |              ^~~~~~~~~~~~~~~~~~~~~~~~~
      |              tracefs_file_exists
make[3]: *** [Makefile:1404: devices/powertop-i915-gpu.o] Error 1

In order to build powertop - I had to build and install the above libraries as per comment by @yeongjoshua

FYI resolved with installing libtracefs-dev and libtraceevent-dev on Debian Unstable.

Same issue on ubuntu 24.04, fixed by installing libtraceevent-dev.
