I am making the android kernel for the first time and after few errors(which I have overcome) I am getting below error log:

(sry for bad code blocks) So, I have found similar questions, but I didn't understand the answer: android kernel build (first time)

when i make it throw 

`LC_ALL=C make O=../out`

it gives me(spoiler - LC_ALL=C don't work how i thought, so i translated it(as #) by myself):

  • On Stack Overflow we prefer **editing** the question instead of *deleting* it and asking a new one about the same problem. I am about [the question](https://stackoverflow.com/questions/52074745/make-error-when-building-android-kernel) you asked 2 days before and deleted it. No worries for the first time, but take it into account for the future questions. – Tsyvarev Sep 01 '18 at 12:05
  • okey... sorry... – Casual Sep 01 '18 at 12:25
