A little python script help me to figure out what difference between two similar project.
I tried to compile linux kernel with compiler flag -O0. This is tough for me because I'm a newbie of linux kernel and I can't solve most of error complain by compiler.
As a GOP(google oriented programming) believer, I googled this question to find some useful suggestion. Most of them said that I can't compile kernel with O0 flag cause it should be compiled with O2 flags!
Fortunately, I found a book called runninglinuxkernel, the author modified linux kernel and compiled it with O0! He also shared this project in github. Since I want to know how to solved the error complained by compiler not just take other project and run it. After I emailed to author, the author replied me but he told me all I need to do is solved every error I met when compile kernel. And it is hard to be explained in a few words.
So I came an idea, why not just compare two project: the original 5.0 kernel and the modifed one? So I make this project to compare the files of two projects intersectin and calulate files hash then compare it.
(poor english, feel free to correct it :D)
