I am completely noob at this. I don't know what the make file is, and I don't know what
But I do know where to download source code and use source somebash.sh then make file (as was told by someone to run those commands).
I did some research and found out ccache can speed up sequential build speed, but I have no idea what am I supposed to do when reading those online instructions (include ccache in path, what path, where and how, and gcc, colorgcc, and bashrc. What are these?)
What is a step-by-step instruction?
