I am on laptop with Intel CPU, maybe AMD-something if disabled on my system.

Gentoo Linux.

Why many compilations are done again and again ?

First make sure everything works ok with the provided source code. Your Port has to do the followings.

1. Pull or download CoreFreq source code
2. Build the project simply as below:

   make clean all

3. Install the binaries and start CoreFreq:

   ## as root
   make install
   depmod
   modprobe corefreqk
   systemctl daemon-reload
   systemctl start corefreqd

   ## as a user
   corefreq-cli

Compilation outside of ebuild is ok, so, looks like something with the ebuild, I will investigate...
