Error with image compilation of openwrt

Hi everyone i'm new with openwrt
I'm facing some problems during the compilation of openwrt image

can someone help me, I don't know what is wrong

the error, and solution, is staring you right it the face ?

sorry, what do you mean?

Do you mean the part that i shouldn't compile it with root privilegis?
Now i'm trying as normal user but it says "permissione denied"

because you already tried to compile as root ...

this isn't openwrt related, but *nix permissions 101.

ok thanks!
